Module Gain and Gain Control

One of the key features of the Z5000 is that is a high-gain module intended to handle signals directly from modules that

generate “large” (high Vpp) signals like filters, VCOs, and other signal generators in a modular synthesizer. The module is also

designed to allow for control of the ratios of the DSP gain, dry/wet mix, and output gain to allow the user to finely craft a

tonal quality for any given sound.

There are two gain control knobs on the module. The IN knob controls the gain of the signal being sent to the DSP and the

OUT knob controls the gain of the signal after is has passed through the MIX knob.

Testing The Z5000

While all Z5000 modules are tested prior to packaging, the following testing procedure will ensure that the module is in full

working order and allow for improved familiarity with the operation of the VU meter.

Before powering the module, set the knobs to the following: CV to MIN, CTRL to MAX, MIX to 50%, and IN to MIN. Select

program 5 on the rotary encoder.

Power the module and send a sawtooth wave to LEFT IN (MONO) and slowly increase the IN knob until the signal is visible on

the VU meter. Then send LEFT OUT (MONO) to a filter or amplifier and slowly increase the OUT knob. You should hear the

signal and effect clearly and equally. Sweep the frequency on the VCO to better hear the effect.

Next, set the MIX knob to DRY to hear the VCO without added effect. Sweep the frequency on the VCO to ensure that the

signal is totally dry. Note, turning the IN knob completely off does not affect the dry signal. Set the MIX knob to WET to hear

only the effect and sweep the VCO frequency to ensure that the signal is totally wet.

Set the CTRL knob to MIN and sweep the VCO frequency. The effect should have minmal effect on the signal.

Program 7: Plate Reverb A

Please note that the Plate Reveb A (7) is a subtle effect. If you do not hear it immediately, simply set the MIX knob to WET and

CTRL to MAX to hear the effect and adjust it to fit the desired effect.

Have fun and we hope that you enjoy your new Z5000 VCDSP!

VU Meter and External Inputs

The VU meter LEDs are set when assembled, however, some vibration during shipping may alter the VU board postion.

Should that occur, gently push the board from the back so the LEDs shift back into place projecting just above the

surface of the front panel.

When handling external (non-modular) inputs the VU meter will not respond significantly to instrument and line level signals

without boosting the gain prior to sending it to the Z5000 as the meter is intended for use at higher signal levels. Do not be

alarmed if the VU meter does not respond to an external input, the module will perform as designed. It should still possible to

hear the signal being passed through the DSP, but in order to make full use of the module it is best to add gain to the signal

Switching and Controlling Effects:

To switch effects on the Z5000, simply alter the position of the Program selector at the top right of the front panel.

An effect parameter (see list on first page) can be controlled by both the CV and CTRL knobs at the top center of

the unit. Applying a control voltage to CV In and adjusting the CV knob allows the user to adjust the degree to

which the control voltage affects the effect parameter. The CTRL knob allows you to directly control the effect

parameter.
