4.3. Installation
a. Mono Use of CONTROL30
The CONTROL30's Input2 can be used as MONO input when necessary setting in the proper way the switch
MONO ON/OFF on the back panel of CONTROL30 itself. When the MONO ON/OFF switch is manually set
to ON position, physically the Input2 will be routed also on the internal Input1 line.
If the VU-meter or the Digital Saturation LED on the CONTROL30 begin to clip (turn red), turn down the Input
level or decrease the volume of the source (instrument, mixer, etc.). If the output level is causing the mixer or
amp to distort, turn the Output Level down.

Outputs
When the MONO ON/OFF switch is set to OFF position, the Input2 is no more routed on the Input1 line and
CONTROL30 works in full stereo configuration.
When the input signal is mono, it has to be connected to the Input2 and the MONO ON/OFF switch must be
set to ON.
b. Standard Use
The CONTROL30 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 CONTROL30
away from other audio equipment that may induce fields and away from the signal wiring.
It is possible that CONTROL30 may pick up noise fields generated by other equipment such as large power
amplifiers; in this case, move the CONTROL30 until the noise goes away.
c. Application Examples
- line Instrument
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.
CONTROL30 has four inputs (two
XLR balanced inputs) and four outputs (two
1/4" TRS inputs and two
1/4" TRS
outputs and two XLR balanced outputs) allowing the CONTROL30 to be used in a classical Stereo In and Stereo
Out connection or in Mono configuration as described above.
MONO. Set manually the MONO ON/OFF switch to position ON. Connect one audio cable to the
of
Input2
the CONTROL30 from a mono source, and one or two other audio cables from the Output1 and Output2 of the
CONTROL30 to a mono/stereo amplification system or one/two mixer inputs.
STEREO. Set manually the MONO ON/OFF switch to position OFF. Connect two audio cables to the Input1
and Input2 of the CONTROL30 from a stereo source, and two other audio cables from the Output1 and Output2
of the CONTROL30 to a stereo amplification system or two mixer inputs.
This connection scheme is suitable also for processing Hi-Fi stereo sources like CD players or recording decks.
To process the signal coming from low signal voltage devices such as Hi-Fi turntable cartridges or microphones,
please insert before CONTROL30 a suitable pre-amplifier (i.e. a RIAA stage for turntables, our
MicTube for
microphones).

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.
Turn on the power of the CONTROL30, pushing the ON/OFF button on the front panel.
Turn on the power of the amplifier/mixer, and adjust the volume.
