Console layout

Each CSP/CSL mixing console has comprehensive input and output sections which can be split further into various stages of processing and routing. All preamps have studio-grade, low-noise architecture for the cleanest possible path throughout the signal chain. The input stages are repeated across each channel of the console, which simplifies operation and enables quick and easy location of various controls. The following pages of this manual are divided up into these stages to explain the details and function of each control.

Mic/Line Input Section

Channel inputs and inserts are provided as XLR and/or 6.3mm jack sockets. The connections for these inputs are assigned as follows.

1. MIC input
   Balanced UnbalancedBalanced| Pin 1 = Ground| Pin 2 = Signal +| Pin 3 = Signal —
   ---|---|---|---
   Unbalanced| Pin 1 = Ground| Pin 2 = Signal +| Pin 3 = Ground

2. LINE input
   Balanced UnbalancedBalanced| Tip = Signal +| Ring = Signal —| Sleeve = Ground
   ---|---|---|---
   Unbalanced| Tip = Signal +| –| Sleeve = Ground

3. L/MONO input

4. RIGHT input
   Balanced| Tip = Signal +| Ring = Signal —| Sleeve = Ground
   ---|---|---|---
   Unbalanced| Tip = Signal +| –| Sleeve = Ground

5. GAIN control
   This control trims the input signal to the optimum level for the channel strip circuitry. Too low a signal level can result in a weak signal-to-noise ratio and too high can result
   in overload and distortion in the signal output.
   The PEAK LED next to the channel fader will give an indication of the signal level. Ideally, the Gain rotary control should be adjusted so that the loudest passages of the
   the input signal (e.g. bass drum beats) will just momentarily trigger the CLIP LED.
   Anything longer than a momentary flicker of the CLIP LED means that the Gain should be reduced. Using the PFL button further down the channel strip gives a more detailed view of the channel level on the main VU LEDs.
   EQ Section

6. HIGH

This control can boost or cut the high frequencies (center 12kHz) by ±15dB (12 o’clock position is zero)

7. MID
   This control can boost or cut the mid frequencies (center 2.5kHz) by ±15dB (12 o’clock position is zero)

8.  LOW
   This control can boost or cut the low frequencies (center 80Hz) by ±15dB (12 o’clock position is zero) ** Channel Routing
   **

9. AUX
   This control governs the amount of signal from the channel routed to the AUX SEND or auxiliary output to external equipment. (This control is post-fader – i.e. the signal routed to AUX SEND is also affected by the channel fader level)

10. . FX
    This control governs the amount of signal from the channel routed to the DSP effects engine. If a jack is connected to the FX SEND connector (see 37 below), this will operate as an extra AUX output (This control is post-fader – i.e. the signal routed to AUX SEND is also affected by the channel fader level)

11. PAN/BAL
    This control adjusts the amount of signal from the channel fed to Left or Right outputs.
    This varies the point in the stereo field that the signal appears. For ST1 and ST2 channels, the PAN control is replaced with a BAL control for the Left/Right balance.

Channel Faders

12.  PEAK LED
    An indicator showing when the signal reaches the maximum level and clipping.

13.  PDF
    Pre-Fader Listen sends the channel signal direct to monitoring. This means that the channel signal is shown on the main VU LEDs. Also, the signal is routed directly to the headphone’s output. This allows the particular channel signal to be checked. If many PFLs or AFLs are selected, all are routed to monitoring.

14. Channel fader 60mm fader to adjust the channel level to the master output. A dB scale is provided to show the level of boost or cut. Graphic Equalizer
    The main EQ is a stereo 7-band graphic equalizer, offering refined audio spectrum sharing and feedback control for live mic situations.

15. EQ sliders.
    Each slider controls a boost or cuts of up to 12dB centered at the specified frequency. DSP Effects Engine
    CSP and CSL series mixers each have an internal 24-bit DSP processor for audio effects, as detailed on the DSP Table (on the following page)

16.  6-segment LED
    Indicates overall input level to DSP

17. Program display
    Indicates selected program (see table on next page)

18. TAP
    Press once to switch the rotary control (27) to PARAMETER 2.

Tap the TAP button rhythmically more than twice to set a tempo for time effects An LED to the left of the Tap switch flashes to indicate time intervals

19. PROGRAM/PARAMETER
    Turn this rotary encoder to select a program.
    The numerical display will flash the selected program number.
    Press the encoder to confirm the selection, the display will stop flashing & the selected program will be active.

Press the encoder again and a dot will appear in the display indicating PARAMETER 1. Turning the encoder will change PARAMETER 1 for the selected program as detailed in the DSP Table on the following page.

Pressing the TAP button (26) will switch to PARAMETER 2 and then turning the encoder will change PARAMETER 2 for the selected program.

These parameter changes are stored for when the program is selected in the future.

41.  IEC mains inlet
    Mains connection. Ensure voltage as indicated. Use IEC lead supplied.

Powering up
Connect the IEC inlet (40) to mains power using the supplied mains lead. In case of the fuse blowing, replace only with the type indicated. If the fuse is repeatedly blowing, refer to qualified service personnel.
The illuminated rocker switch activates the main power to the unit.

Phantom power
In addition to the mains power switch, the rear panel has an additional rocker switch which when switched on, enables +48V phantom power to the XLR input connectors. This is mainly used for condenser microphones that do not have an internal battery or to remotely power D.I. boxes for patching instruments directly into the mixer.
Connecting Speakers (CSP only)
When connecting speakers to the CSP-series mixers, ensure that the combined load for each output (left or right) is no lower than 4 Ohms (4Ω). To make sure of this, check the speaker manufacturer’s information.

If connecting more than one speaker to an output channel, observe the following calculation method.

Note: normally, speakers will be connected in parallel by connecting a speaker lead from one to another.
Most PA and sound reinforcement speakers are 8Ω, so we consider that 1/8 + 1/8 = 1/4.
Therefore, when connecting 2 x 8Ω speakers together in parallel, the resulting total load is 4Ω.

It is also important to ensure that the power delivered to the speakers will not overload them.

When connecting 2 x 8Ω speakers together on one channel, each speaker will equally receive half of the output of that channel.

Troubleshooting

No power “ON” LED on the control panel| Ensure mains outlet voltage is correct for the unit
---|---
Use power lead supplied with the unit and check condition is OK
Check power is switched on at the rear panel
Check IEC fuse — if blowing fuses refer to qualified service personnel
Power LED is on but no other LEDs and no output| Check input signals and condition of connection leads
Check GAIN is not too low on channel input(s)
Check channel fader, GAIN, and EQ controls are not turned fully down
Check MASTER faders are not fully down
When using condenser microphones, use an external phantom power unit
Check that PFL buttons are all switched out
Check that all Graphic EQ sliders are not fully down
Power light and VU LEDs lighting but no main or speaker output| Check that Main L+R outputs are not muted
Check MASTER faders are not fully down
Check speakers are functional, and leads are OK and connected properly
“PROT” indicator is lit and no output (CSP only)| Protect mode — switch off power immediately

Disconnect speakers and switch the power back on to the unit.

If the unit powers up OK and the PROT light is off, refer speakers to qualified service personnel. If PROT is still lit, switch off the power and refer CSP unit and speakers for checking by qualified service personnel.

VU LEDs do not show MAIN output levels| Check that PFL buttons are all switched out
Output is very loud or distorted| Check the level of the input signal is not too high
Reduce channel GAIN and EQ settings
Reduce channel and MAIN faders levels
Ensure Hi-Z line-level input(s) not connected via XLR
Check AUX and EFFECT level controls and reduce if necessary
Output is working but at a very low level| Check input audio source level is not too low
Ensure low impedance mic or line signal is not connected via jack
Increase channel GAIN control and EQ settings if turned down
Increase channel and MAIN faders levels
Feedback (loud squealing or howling from mics)| Face microphone away from speakers and monitors
Reduce channel GAIN level and EQ level(s)
Reduce AUX and/or EFFECT levels
Reduce channel and/or MAIN fader levels
