Preset Mode, Stompbox Mode, Direct 7 Mode

Preset Mode lets you switch the sound settings configured and stored on the amp. There are 128 memory slots arranged in 32 banks of 4 presets each. Stompbox Mode is tailored to Hughes & Kettner amps. It lets you switch channels directly as you would on a conventional amp. Please check your amp’s manual to see if it is set up to handle this function. Direct 7 Mode lets you store and select the seven most popular presets directly.

Press and hold TAP in combination with A for three seconds to select modes via BANK UP/DOWN rather than with the sliding switch on the connector panel.
Switching with a combination of buttons lets you access a fourth option called Bank Direct Mode. Think of it as an alternate Preset Mode that activates the target preset immediately when you switch between banks. In other words, you do not have to select and confirm the preset first with one of the A-to-D buttons on the FSM 432-MK IV.
The following will then appear in the display:

Bank Direct Mode

Connecting additional switches and expression pedals

Control 1: Press TAP and D until 07 appears in the display (7 = Volume preset). The dot behind the second digit starts flashing. Then simultaneously release the buttons and set the controller number with the Up/Down buttons. Confirm your selection by pressing TAP.
Control 2: Press TAP and C until 64 appears in the display (64 = Volume preset). The dot behind the first digit starts flashing. Then follow the same procedure as for Control 1.
You can find a list of controller numbers in the operating manuals of Hughes & Kettner amps that support these functions.

Global and Preset Mode

You can assign a function to an expression pedal or switch globally or individually for each preset.
Press TAP and B to change the mode, holding the B button down for three seconds. The following will then appear in the display:

Troubleshooting

If your amp fails to respond when you engage a connected expression pedal, proceed as follows:
Press TAP and Down when connecting the power supply or MIDI Out to the power supply. The FSM 432-MK IV display will then show the positions of pedals connected to controller inputs. Values are given as a percentage (099%) of the pedal’s total control range. The LEDs run from left to right as the value increases. Press TAP to exit the menu.

Power supply

The FSM-432 MK IV can run on phantom power provided via the 7-pin MIDI port from amps such as the Black Spirit and Grandmaster. Please see the manual of your amp to learn more. In this case, you will not need a dedicated power supply. You can also plug a 5-pin MIDI cable into the FSM-432 MK IV’s MIDI Out port to connect it to any MIDI-enabled device. In this case, you have to operate the FSM-432 MK IV with a standard DC or AC power supply providing at least 250 mA at a voltage between 9 and 15 volts.
*7-pin MIDI Cable is included.

MIDI

The MIDI In port serves to connect outboard MIDI devices that send controller commands. The FSM-432 MK IV then operates as a true MIDI merger, routing incoming commands from the MIDI In port through to the MIDI Out port.To change the MIDI channel press A while connecting the 7-pin MIDI cable or power supply to the FSM- 432 MK IV. Switch the MIDI channel with Bank Up/Down. Press Tap to exit.
