ENGL Z-9 Custom Footswitch User Manual

ENGL Z-9 Custom Footswitch

Introduction

Congratulations on your choice – the Z-9 Custom Footswitch is sure to serve you well as the switching center for your rig! With this custom-designed foot controller, you own a general-purpose tool well-suited for operating specific ENGL amps via
S.A.C. (Serial Amp Control; ENGL’s proprietary data protocol). As alternative to this, the Z-9 can be configured to control MIDI-enabled amps and effect devices. The ENGL Z-9 features an unique auto configuration function that – according to the type of connected cord configures it as an ENGL S.A.C. system switching center or as a basic MIDI foot controller offering 10 MIDI patches. Carrying on the ENGL tradition of turning out foot controllers boasting rugged design and striking visuals, the ENGL Custom Z-9 Footswitch is a very robust device housed in an elegant stainless steel chassis.

A quick rundown of its features and functionality follows.

When configured in S.A.C. mode to remote control specific ENGL amps and 19″ rack devices, theZ-9:

1. selects channels directly via reciprocal triggering (that is, A/B switching. See page 15 to learn more.).
2. offers two freely programmable buttons that serve to control programmable sound-shaping and special functions on ENGL amps. These two special function buttons may also be integrated into the chain of four reciprocal trigger (A/B) switching functions. This affords you direct access to the switchable Tube Driver and T.D.EQ on the ENGL Special Edition amp, as well as to Preamp Defeat on the ENGL 570 Tube Preamp.
3. provides access to the switchable Master A/B, for example, on the Special Edition Amp (via the four channel selector buttons; the function is activated by pressing the button twice).
4. connects to your ENGL amp, power amp or preamp’s S.A.C. port via a conventional stereo cord with 1 /4”jack plugs. In this case, the stereo cord delivers the current required to power the Z-9!

When configured in MIDI foot controller mode, the Z-9:

1. selects 10 MIDI patches numbered 1 to 10 (MIDI program numbers or MPN for short) in two banks comprising five MPNs each.
2. is supplied with power via a 5-pin MIDI cord connected to ENGL amps, power amps or preamps equipped with a MIDI interface (MIDI IN), and a phantom power option that is enabled via the ENGL MIDI Foot Controller switch. An outboard power unit is not required for this type of configuration.

A tremendous advantage of the ENGL Z-9 Custom Footswitch is that it offers two remote control options – MIDI and Serial Amp Control. In the event of a damaged cord, you can immediately change over to the other option. What’s more, cords equipped with stereo 1/ 4″jack plugs are readily available, so S.A.C. is always a viable option.

Power Supply

This socket accepts an external power unit for the Z-9, When connecting a power unit, ensure voltage and current comply with the foot controller’s specifications. You may connect an AC (alternating current) power unit as well as a 100-mA DC (direct current) power unit. The AC voltage range is 7 to 14 volts; the DC voltage range is 9 to 20 volts. The polarity at the plug plays no role.
IMPORTANT NOTE: This type of power supply is not required if the foot controller is connected to an ENGL amp that features an S.A.C. Port or a MIDI In port that provides phantom power for the foot controller.

Serial Amp Control Out
This stereo jack routes out S.A.C. commands. Connect it to the S.A.C. port (stereo jack plug) on an ENGL amp using a cord equipped with stereo 1/4″ jack plugs. When connected to an ENGL amp’s S.A.C port, this stereo cord also provides powertotheZ-9.
Heads up critical info: Connect the Z-9 Foot Controller’s S.A.C. Out stereo jack to an ENGL amp’s S.A.C. port (stereo jack) only! Connecting it to any other jack may damage the Z-9 and amp!

MIDI OUT
This 5-pin DIN port serves to route out MIDI data. Connection the MIDI In of an ENGL amp or a MIDI-enabled device using a suitable MIDI cord. A 5-pin cord connected to the MIDI IN port of an ENGL amp can provide power to the foot controller. To this end, you must set the ENGL amp’s phantom power selector accordingly, that is, to the ENGL MIDI Foot Controller position.

Detailed descriptions of functions with examples and tips follow:

1. Selecting channels and sound-shaping and special functions on ENGL amps in Seria I Amp Control mode
   This mode is only active when the Z-9 Foot Controller is connected to the S.A.C. port on an ENGL amp using a cord with stereo 1 / 4″jack plugs. As soon as the foot controller is powered up, LEDs 1 to 4 act as a light chain flashes to indicate S.A.C. mode is active, illuminating successively from right to left while LEDs 5 and 6 flashes. In this mode, you can switch four channels on ENG Lamps directly by pressing the Channel 1 to Channel 4 buttons, and control two sound-shaping or special functions using the Function 1 and Function 2 buttons. If required, the two Function buttons can also be configured as reciprocal triggers (or A/B switches, if you prefer) for selecting auxiliary channels (for instance, the E670’s Tube Driver or the ES 70’s Preamp Defeat).
   Examples: To select the Clean channel (Channel 1 ) on the Special Edition Amp E670: -> Press Channel 1 briefly; LED 1 above the button lights up; Z-9 sends the corresponding S.A.C. command to S.A.C. Out; To select the Lead I channel (Channel 3 ) and Master B on the ENGL Special Edition Amp E670:
   -> Press Channel button 3 twice; LED 3 above the button flashes;
   Z-9 sends the corresponding S.A.C. command to S.A.C. Out.
   Note: To this end, Function 1 must be configured accordingly in the Function 1 Setup routine; that is, Function 1 ‘s configuration may not be equal to Fl-1 .
   To select the Crunch channel (Channel 2) and Master A on the ENGL Special Edition Amp E670:
   -> Press Channel 2; LED 2 above the button lights up.
   Z-9 sends the corresponding S.A.C. command to S.A.C. Out.
   Note: To this end, Function 1 must be configured accordingly in the Function 1 Setup routine; that is, Function 1 ‘s configuration is not equal to F1-1 .
   To activate Hi Gain and Gain Boost on the Special Edition Amp E670 or the Preamp E570:
   -> Press Function 1; LED 5 above the button lights up;
   Z-9 sends the corresponding S.A.C. command to S.A.C. Out.
   Note: To this end, Function 1 must be configured accordingly in the Function 1
   Setup routine; that is, Function 1’s configuration is equal to F1-6.
   Mega Lo Punch (M.L.P.) on the Special Edition Amp or Preamp E570 activates:
   -> Press Function 2; LED 6 above the button lights up;
   Z-9 sends the corresponding S.A.C. command t0 S.A.C. Out.
   Note: To this end, Function 2 must be configured accordingly in the Function 2 Setup routine; that is, Function 2’s configuration is equal to F2-3.

• See Comments on page 13 and 14 to learn what this designation means.
  A tip from the designer:
  Serial Amp Control is a convenient remote control option for your ENGL amps. It comes highly recommended if you do not work with a MIDI system or hands- free selection of channels and control of two sound-shaping or special functions of the amp (for example, Hi Gain and Mega Lo Punch via the two Function buttons) suffices for your musical purposes.
  If you want or need a greater range of remote control options for manipulating your amp’s sound-shaping and special functions on the fly, your best bet is to program the desired settings for these functions to the 10 MIDI patches and access the presets in MIDI mode.

  2. Configuring the Function 1 and Function 2 buttons:
     To assign a sound-shaping and special function to Function 1 via the Function 1 Setup routine:
     -> Press and hold Channel 1 and Function 1 simultaneously until LED 5 above the Function 1 button flashes.
     Note: If the Function 1 button is programmed for A/8 switching (F1-5, “reciprocal triggered” with the four channels) and the B function is currently active, LED 5 above the button will flash before you activate the Function 1 Setup routine. In this event, switch to the A function first and watch the LED to ensure it indicates you have activated Function 1 Setup. -> Press the Function 1 button to confirm the Function 1 Setup routine.

  3. LED 5 above the Function 1 button lights up and the amp function(s) currently assigned to this button is/are activated. If the Function 1 button is programmed for A/B switching (F1-5, “reciprocal triggered” with the four channels), the amp will switch to the corresponding channel (for example, Tube Driver or Preamp Defeat). One of the LEDs 1 to 4 located above the Channel 1 to Channel 4 buttons will light up or flash to indicate the amp’s sound- shaping or special function that is currently assigned to the Z-9’s Function 1 button.
     Here’s how to select the desired sound-shaping or special function on your amp via the Z-9’s Function 1 using one of the four Channel 1, Channel 2, Channel 3 and Channel 4 buttons: Press the appropriate button once or twice for the given configuration. The table on page 13 lists the assignments of sound- shaping and special functions to Function 1.
     Example: Say you want Function 1 to control the sound-shaping functions Modern/Classic (S.A.C. command F1-2) on the Special Edition Amp E670 or Preamp E570. Note that for purposes of this example, the sound-shaping functions Gain Boost and Hi Gain (via the common S.A.C. command F1-6) are currently assigned to Function 1.
     -> Press and hold Channel 1 and Function 1 simultaneously until the LED 5 above the Function 1 button flashes.
     -> Press the Function 1 button to confirm the Function 1 Setup routine.
     LED 5 above the Function 1 button lights up and LED 2 above the Channel 2 button flashes to indicate the current configuration F1-6.
     -> Press Channel 2 once or twice until LED 2 lights up to indicate the new Function 1 configuration, which is F1-2.
     -> Store it by pressing and holding the Function 2 button until LED 6 lights up once briefly.
     To assign a sound-shaping and special function to Function 2 via the Function 2 Setup routine:
     -> Press and hold Channel 1 and Function 2 simultaneously until LED 6 above the Function 2 button flashes.
     Note: If the Function 2 button is programmed for A/B switching (F2-5, “reciprocal triggered” with the four channels and Function 1 configurations other than Fl-1 ) and the B function is currently active, LED 6 above the button will flash before you activate the Function 2 Setup routine. In this event, switch to the A function first and watch the LED to ensure it indicates you have activated Function 2 Setup.
     -> Press the Function 2 button to confirm the Function 2 Setup routine.
     LED 6 above the Function 2 button lights up and the amp function(s) currently assigned to this button is/are activated. If the Function 1 button is programmed for A/B switching (F2-5, means “reciprocal triggered” with the four channel buttons), the amp will switch to the corresponding channel (for example, Tube Driver EQ on the E670). One of the LEDs above the Channel 1 to Channel 4 buttons will light up or flash to indicate the amp; s sound-shaping or special function that is currently assigned to the Z-9’s Function 2 button.
     Here’s how to select the desired sound-shaping or special function on your amp via the Z-9’s Function Z using one of the four Channel 1, Channel 2, Channel 3 or
     Channel 4 buttons: Press the appropriate button once or twice for the given configuration. The table on page 13 lists the assignments of sound- shaping and special functions to Function 2.
     Example: Say you want Function 2 to control the sound-shaping function Mega Lo
     Punch (S.A.C. command F2-3) on the Special Edition Amp E670 or the Preamp
     E570. Note that for purposes of this example, the sound-shaping functions Ultra
     Bright & Mid Edge (via the common S.A.C. command F2-6) are currently assigned to Function 2.
     -> Press and hold Channel 1 and Function 2 simultaneously until LED 6 above the Function 2 button flashes.
     -> Press the Function 2 button to confirm the Function 2 Setup routine. LED 6 above the Function 2 button lights up and LED 2 above the Channel 2 button flashes to indicate the current configuration F2-6.
     -> Press Channel 3 once or twice until LED 3 lights up to indicate the new Function 2 configuration, which is F2-3.
     -> Store it by pressing and holding the Function 1 button until LED 5 lights up once briefly.
     A tip from the designer:
     Consult the configuration table on page 13 for the Function 1 and Function 2 buttons’ assignments to sound-shaping or special functions on your ENGL amp. There is an alternative method that is very helpful when you don’t have the configuration table at hand. Use the two Function 1 Setup and Function 2 Setup routines to run a quick configuration check:
     -> Press Channel 1 and Function 1 simultaneously to access Function 1 Setup; confirm by pressing Function 1 as soon as the LED 5 above the button flashes.
     -> Press Channel 1; the LED 1 above the button lights up or flashes, depending on its prior status.
     -> Press Function 1 several times; LED 5 above the button lights up and extinguishes while the LED for the given sound-shaping or special function on your ENGL amp does the same. Watch the amp and note which amp function responds when you press Function 1.
     -> Press the Channel 2, Channel 3 and Channel 4 buttons and follow the same procedure.
     ->Goto the second configuration level (F1-5) by pressing Channel 1 once or twice; press Function 1 and note which sound-shaping or special function on the amp responds.
     -> Goto the second configuration level (F1-6 to F1-8) of the Channel 2, Channel 3 and Channel 4 buttons and proceed as described above.
     -> Once you have found the desired sound-shaping or special function for Function 1 (for example, Modern/Classic, which is accessed via the configuration F1-2 ), you can store it by pressing the Function 2 button.
     -> Press and hold the Function 2 button until LED 6 lights up once briefly.
     Proceed in the same manner for Function 2:
     -> Press Channel 1 and Function 2 simultaneously to access Function 2 Setup.
     -> Confirm by pressing Function 2 as soon as the LED 6 above the button flashes.
     -> Once you have found the desired sound-shaping or special function for Function 2 (for example, Mega Lo Punch/M.L.P., which is accessed via the configuration F2-3), you can store it by pressing the Function 1 button.
     -> Press and hold the Function 1 button until LED 5 lights up once briefly.

  4. the LED above the respective Channel button light to indicate the given configuration. The second level comprises F1-5 to F1-8 and F2-5 to F2-8, the LED above the respective Channel button flashes to indicate the given configuration. With the four Channel buttons and these two configuration levels, you have up to eight different configuration options for Function 1 and eight options for Function 2. The actual number of possible assignments depends on the model of ENGL amp. Some of the sound-shaping and special functions of ENGL amps are assigned to the same SAC. command, e.g. Gain Boost & Hi Gain to F1-6. This has the advantage that you can control two sound-shaping functions in different main channels of the amp using one of the two Function buttons.

Selecting MIDI patches in MlDI mode

MIDI mode is active as soon as the Z-9 Foot Controller is powered externally via the mains socket (power supply) or by an ENGL amp via a 5-pin DIN cord. LEDs 1 to 5 act as a light chain to indicate MIDI mode is active, illuminating successively from left to right while LED 6 flashes. In this mode, you can access 10 MIDI patches in two banks using the Patch 1 /6 to Patch 5/10 buttons. Press the Bank A/B button to switch between Banks A and B.

Examples:

To select MIDI patch 3:

-> Press Patch 3/8 briefly; the LED 3 above the button lights up; MIDI Out sends MPN 3.

To select MIDI patch 7:

-> Press Bank A/B; LED 3 and LED 6 flash.
-> Press Patch 2/7 briefly; the two LEDs 2 and 6 light up; MIDI Out sends MPN 7.

A tip from the designer:

If feasible, store your most frequently used MIDI presets on amps or effect devices in a single bank, that is, in MPNs 1 to 5. This lets you access your fave sounds swiftly without having to change banks.

Handling and Care

Keep the foot controller safe from hard knocks and shocks.

Avoid storing the foot controller in damp or dusty rooms to spare jacks and switches.

Never use caustic or scouring detergents to clean the foot controller’s housing. Use a soft, damp cloth or sponge with diluted soapsuds or a standard brand of mild d dishwashing liquid instead. Never use solvents they can dissolve the top panel labels.

Keep liquids well away from the foot controller, particularly the interior of the housing. Glossary

MIDI Programs:
In this manual, MIDI programs are called MPNs (MIDI program numbers) as well as
MIDI patches. The terms are used interchangeably.
Though the MIDI standard defines program numbers 000 to 127 (0hex to 7Fhex), almost all MIDI devices indicate these programs using· a 1-to-128 numbering scheme.
The Z-9 Foot Controller selects the first 10 patches thereof (patch 1 to 1 0; that is, 000 to 009 or 0hexto 9hexaccording to the MIDI protocol).

MIDI Channel:
The MIDI standard defines 16 channels for sending and receiving MIDI data. The Z-9 Foot Controller sends MIDI program change commands via MIDI channel 1 (channel 00 or 0hex, according to the MI DI protocol).

MIDI Bank A and B:
The Z-9 offers two banks of five MIDI patches each for a total of 10 MPNs. The five
MPNs in the active bank can be accessed directly at the push of a button

S.A.C.:
Short for Serial Amp Control, a proprietary ENGL data protocol that is understood by ENGL amps with an integrated S.A.C. interface. The great advantage of this remote control option is that a standard cord with stereo 1 / 4″jacks provides the link between the amp and Z-9.

Reciprocal trigger:
A/B switching by any other name: “Reciprocal trigger” means that pressing a button activates the newly selected function and simultaneously deactivates the previously active function. In other words, the button is configured as an A/B rather than an on/off switch.
In S.A.C. mode, the Z-9’s first four buttons are configured as A/B switches to select channels (for example, Clean, Crunch or Lead) on ENGL amps. You can also configure
Function 1 and Function 2 as A/B switches (“reciprocal triggered” with the four channel buttons) to extend your remote control options beyond mere channel switching.
Note: do not confuse A/B switching with Master A/B switching that can also be executed via the four channel buttons if the configuration in Function 1 Setup is set accordingly: in this case the switching process is a typical on/ off function between Master A and Master Band it is executed by pressing the same button twice.

Function 1 Setup and Function 2 Setup:
These two configuration routines serve to assign an ENGL amp’s sound-shaping or special functions to the two Function 1 and Function 2 buttons. They let you configure Function 1 and Function 2 to remote control amp features such as Bright, Presence A/ B, and so forth.

Troubleshooting

None of the LEDs on the Z-9 light up after plugging in the power supply cord and the MIDI cable or stereo cord equipped with 1/4″ jacks.

When powering the Z-9 via the MIDI cord:

• Is your MIDI cord equipped with the required 5-pin connector?

• Does it have the correct pin assignments (refer to page 18 for pin connections)?

• Is the MIDI cord defective (say, a short circuit or broken wire)?

• Is the power supply selector (phantom power) for the ENGL foot controller set properly on the ENGL amp (that is, to the ENGL MIDI Foot Controller position)?

• Check cable connections: Is the foot controller’s MIDI Out connected to the MIDI In on the ENGL amp?

• When the Z-9 is powered via a MIDI cord, a 1/ 4″ plug may not be inserted in the Serial Amp Control Out port, nor may a connector be plugged into the external power socket.
  When powering the Z-9 via a stereo cord plugged into the S.A.C. Out:

• Is the cord a stereo cord equipped with the required 3-terminal plugs?

• Is the stereo cord defective (say, a short circuit or broken wire)?
  Are its plugs’ terminal assignments correct?
  When powering the Z-9 via an external power unit:

• Does the external power unit supply the required current and voltage? (refer to Technical Data on page 17).

• Is the external power unit or cord defective?

• Is there a loose connection in the cord’s plug?
  Does the plug fit snugly in the foot controller’s socket?

• When the Z-9 is powered via an external power unit, a 1/ 4″ plug may not be inserted in the Serial Amp Control Out port.

The connected amp or effect device fails to respond to MIDI program change commands when you select an MPN on the Z-9.

• Is the MIDI cord defective (say, a short circuit or broken wire) and does it have the correct pin assignments (refer to page 18 for pin connections)?

• Check cable connections: Is the foot controller’s MIDI Out connected to the
  MIDI In on the ENGL amp or effect device?

• Is the amp or MIDI effect device set to MIDI channel 1?
  To check this, you can set the amp (or effect device) to OMNI Receive mode.
  In this mode, MIDI data are received via all 16 channels.

• Is the connected MIDI device able to switch to the selected MIDI patch?
  The number of MIDI patches on the MIDI device may be limited (look this up in the MIDI device’s operating manual).

• Is your ENGL amp or ENGL MIDI peripheral device equipped with a display providing visual confirmation?
  If not (as is the case with the E670 and Z-7), perhaps you have not programmed different settings (presets) to the MIDI patches. This may explain why there is no response when you select presets. Program presets with different settings and try again.

• Is a plug inserted into the two-way foot switchback of the ENGL device?
  When you plug in a two-way footswitch, the channel switching option on the amp/ preamp/ power amp is disabled, as are the S.A.C. and MIDI remote control options.
  Choose one remote control option – S.A.C., MIDI or two-way footswitch. Do not combine these operating modes!

When operating the Z-9 in S.A.C mode, the connected ENGL amp does not respond when you press buttons to select channels or switch special functions.

• Check the cord connecting the amp and Z-9 for a short circuit or broken wire.
• Is the cord leading from the amp inserted in the fightback (S.A.C. Port)?
• Try switching functions manually on the amp to see if it responds.
• Is a plug inserted in the two-way foot switchback at the amp?
  Connecting a two-way footswitch disables the channel switching option, as well as the S.A.C. and MIDI remote control options.
  Do not combine remote control options! Opt for S.A.C., MIDI or the two-way footswitch.
