c. Application Examples

  - LINE INSTRUMENT 

When the MONO ON/OFF switch is set to OFF position, the

INPUT 1 

and 

β

VERB works in fully stereo configuration and MUST have stereo input signals for a proper functioning of 

the process algorithm.
When the input signal is mono, it has to be connected to the 

 and the MONO ON/OFF switch MUST be 

INPUT 2

set to ON.

4.2 Analog

a. Levels Setting 

Proper setting of the input and output levels is crucial in order to achieve the maximum signal-to-noise ratio. It 
is possible to say that it is usually best to set both input and output level controls at 3/4 or 75% of full. This will 
decrease the possibility of overload distortion and keep the amount of background noise to a minimum.

If the VU-Meters or the Digital Saturation LED on the 

β

VERB begin to clip (turn red), turn down the Input level 

or decrease the volume of the source (instrument, mixer send, etc.). If the output level is causing the mixer or 

amp to distort, turn the Output Level down. 

4.3 Installation

a. Mono Use of 

β

VERB

The 

β

VERB's INPUT 2 can be used as MONO input when necessary setting in the proper way the switch 

MONO ON/OFF on the back panel of 

β

VERB itself.

When the MONO ON/OFF switch is manually set to ON position, physically the INPUT 2 will be routed also 
on the internal INPUT 1 line.

b. Power Up Setting 

After making your connections, turn on the system power using this procedure:
Before turning on the 

β

VERB power, check if:

˙

All connections been have made correctly.

˙

The volume controls of the amplifier or mixer are turned down.

Insert the Power plug into the POWER input on the rear panel of the 

β

VERB and plug the power cord into an

 AC outlet. 
Turn on the power of the 

β

VERB, pushing the ON/OFF button on the front panel. 

Turn on the power of the amplifier/mixer, and adjust the volume. 

The 

β

VERB may be placed almost anywhere: on a table, on top of an amp, next to a mixing console. If it will 

be on furniture, check the rubber feet provided to the bottom of the unit. Make sure to place the 

β

VERB away 

from other audio equipment that may induce fields, and away from the signal wiring. It is possible that 

β

VERB 

may pick up noise fields generated by other equipment such as large power amplifiers; in this case, move the 

β

VERB until the noise goes away.

When connecting audio cables and/or turning power on and off, make sure that all devices in your system have 
their volume controls turned down.

outputs and two XLR balanced outputs) allowing the 

β

VERB to be used in a classical Stereo in and Stereo Out 

connection or in Mono configu

ration as described above. 

β

VERB has four inputs (two 1/4" TRS inputs and two XLR balanced inputs) and four outputs (two 1/4" TRS
