Receiver IR: the built-in IR receiver gives general volume control of the CA120 and
its MUTE ON / OFF function from the REVO-IR remote control included with the
unit.

4. OPERATION AND USAGE

4.1. Start up and default mode
Start up the CA120 by connecting the equipment to an external power source to which
the DC 24V connector of the CA120 has already been connected. The LED indicator ON/STBY
immediately lights up on the front panel. We recommend you turn on all the devices in the
following order: sound sources, mixer, equalisers, active filters and processors and, finally power
amplifiers. Powering off should be done by following the exact reverse sequence. Following this
order, the introduced noise due to turning on or switching off the devices will not affect those
further on in the chain and will be inaudible.
The system defaults to volume adjustment mode. In this mode, the VOL/MUTE knob on
the front panel acts on the general output volume of the CA120. This controller has a maximum of
64 steps between the unit's minimum and maximum volume. When turned, it will adjust the
volume while the LED LEVEL light is flashing. When the controller is turned to the left or to the
right, this flashes while the output volume increases or decreases. The light stops flashing when it
reaches either end of the scale and it is no longer possible to increase or decrease the volume of
the unit.
Quickly press the VOL/MUTE controller to activate/deactivate the mute function of the
unit (MUTE ON/OFF). The MUTE LED lits when the mute function is activated.
If you adjust the volume using the infrared remote control, the LED LEVEL y MUTE
visual indicators are exactly the same as those seen when adjusting these with the knobs on the
front panel.
