Proel exaverb Quick Start Guide
To connect this unit you need unbalanced (TS) ¼” cables carrying line level signals from your
mixer or other line level source to be connected to ¼” jacks of this unit rear panel.
If your sound source is monophonic please connect the cable to “LEFT/MONO” input jack only.
For stereo sound sources use both “LEFT/MONO” and “RIGHT” jacks by connecting two discrete
cables to each of the two inputs.
Set the output level of your sound source (mixer or other line level source) and the input gain
(“INPUT LEVEL”) so that “CLIP” LED will never turn on.
Connect unit outputs (“OUTUPT LEFT” and “OUTPUT RIGHT”) to your mixer effects return or
stereo line level input.
Please make sure “FX/BYPASS” LED is turned off.
Rotate the “OUTPUT LEVEL” knob until reaching the desired output signal level.
Now you can choose the effect you want to use by rotating the selection knob (7).
Using “MIX” knob set the quantity of direct signal (DRY) versus effect signal (WET) to be sent to
outputs.
In order to obtain the best possible results please refer to page 14 connections examples.

Front Panel
1) INPUT LEVEL Knob
This knob allows you to set input signal gain.
2) Mix Knob
This knob is useful to balance original sound versus effect sound to zetaverb output. Rotating the
knob counter clockwise (towards “DRY”) you’ll listen more of the original signal. Rotating the knob
clockwise (towards “WET”) you’ll listen more effect.
3) OUTPUT LEVEL Knob
This knob sets the output level of overall signal from the processor.
4) CLIP LED
This LED turns on when the processor input signal level is too high. In this case you should reduce
the input level by “INPUT LEVEL” knob.
) VARIATION Knob
This knob allows you to modify the value of the parameter associated to each effect.
Each effect parameters editable using the “VARIATION” knob are listed in TABLE 1 (page 11).
At each effect change the last selected parameter value is stored. When an effect is recalled the
stored parameter value is recalled regardless of current position of VARIATION knob. Thus in this
condition by rotating the knob there could be no value exchange unless the VARIATION knob
passes thru stored VARIATION value point. Once the VARIATION knob passes thru the stored
point it’s possible to modify the effect value. In order to verify that VARAITION knob has passed
the stored value point you can see the FX/BYPASS LED (8) in this case the LED will briefly flash.
