INDICATION
ThesegreenLEDsindicateaudiosignalintheinput.
VOLUME COMBO XLR
These rotary knobs are for adjusting volume level of the universal mono inputs.
First six inputs can be use as balanced line level as well as microphone level
inputs. The phantom power can be activated for these inputs separately in rear
panel. The input gain selector is located in the rear panel too.
VOLUME STEREO RCA
These rotary knobs are for adjusting volume level of the line level RCA inputs.
Input 7, 8 and 9 are line level, unbalanced, stereo inputs.
MONITOR
This is volume control for adjusting audio level in the balanced monitor output.
In this output can be linked audio from the combo inputs.
MONITOR ON/OFF BUTTON
If this button is in the “ON”position, all combo inputs are linked in to monitor
output. At this moment only input 7, 8 and 9 are available in the master, mono
and rec. outputs. When the button is off, all inputs are linked in to main, mono
and rec. output, at this moment monitor output is inactive.

DC 24V CONECTOR
This connector is designed to power up preamplifier when the main power is
unavailable. Use only 24V power supply or batteries and take attention to polar-
ity during the wiring. If both, AC and DC power are connected; preamplifier will
use main AC power.

This is line level, balanced output, 6.3mm TRS connector.
MONITOR OUTPUT
This is line level, balanced output, 6.3mm TRS connector. Signal in this
output is available when MONITOR BUTTON is in the ON position. In this output
only signal from combo
connectors (input 1 - 6 ) is available.
REC OUTPUT
This is line level, unbalanced stereo output, RCA connector. Signal in this output
is independent from master, mono or monitor knobs. The signal level in this
output depends from input volume controls only.

PRIORITY
Input 1 can be set as priority input. To set priority, please turn priority potenti-
ometer to the right until the end. To deactivate priority turn to the left until the
end.
