9. AUX 1&2 RETURNS
Pot for controlling the level of the AUX RETURN 1 and
2.
10. SOLO MODE
Allows to select if the listening and the visualization of
the channels selected with the SOLO buttons are PRE-
FADER (PFL) or POST FADER (AFL).
a) PFL : PRE-FADER LEVEL, the input signal, already
controlled by the channel EQ, is shown on the LED
bargraphs and sent to the headphones output. The PFL
mode has to be used for setting the right level for the
input signal (usually around 0dB) and to avoid
distortions.
b) AFL : AFTER-FADER LEVEL, the input signal,
already controlled by the channel EQ and by the
channel fader, is shown on the LED bargraphs and sent
to the headphones output. The AFL mode can be used
to listen the signal sent to the MAIN MIX.
11. SOLO ACTIVE
Indicates when at least one SOLO button is pressed on
the input channels and when the AFL MODE is
selected.
12. LEVEL SET
This LED lights when one or more SOLO button are
pressed and the PFL mode is selected. This is the typical
SOLO mode used to set the input level of the channels.
13. LEVEL
12-LED BARGRAPHS for the visualization of the signal
assigned to the MAIN MIX outputs, the signal of the
channels selected by the SOLO buttons or the signal
selected in the C. ROOM SOURCE section.
The LEDs are of three different colors:
• green = show the normal operative level of the signal
(from -30 to +4 dB);
• yellow = show a high operative level of the signal
(from +7 to +10 dB);
• red (CLIP) = show a too high signal level, near to the
overload of the mixer output stage.
14. MAIN MIX LEVEL
Slider for control of the general volume.
15. ALT 3-4 LEVEL
Slider for control of the volume of the ALT 3-4 mix.
16. PHONES / C. ROOM LEVEL
Slider for controlling the level of the HEADPHONES
outputs and of the CONTROL ROOM outputs.
Using the C. ROOM SOURCE buttons, it’s possible to
assign to these outputs the signal coming from the
MAIN MIX, from the ALT 3-4 mix and from the 2-TRK
input.
When one or more SOLO buttons on the input channels
are pressed, the signal of the selected channels can be
heard from the headphones and control room outputs.
According to the position of the SOLO MODE switch,
this signal can be PRE- (PFL) or POST-FADER (AFL).
17. C. ROOM SOURCE
Buttons for assigning the signal to the headphones and
control room outputs and to the LED bargraph.
18. 2-TRK TO MIX
This button assigns the signal coming from the 2-TRK
input to the MAIN MIX.
19. ALT 3-4 TO MIX
This button assigns the signal coming from the ALT 3-
4 mix to the MAIN MIX. Thanks to this button, the ALT
3-4 mix can be used as a stereo sub-group.
20. ON
LED indicating when the mixer is switched on.
21. +48V
LED indicating when the +48V phantom power is
switched on.
7. REAR panel (pic 5)
1. MAIN MIX XLR OUTPUTS
Two balanced XLR-M connectors (+4 dB). These are
the MAIN MIX balanced outputs.
2. MAIN MIX JACK OUTPUTS
Two unbalanced JACK connectors (+4 dB). These are
the MAIN MIX unbalanced outputs.
3. MAIN MIX INSERTS
STEREO JACK connectors: allow to use an external
device (equalizer, compressor, etc.) to process the
signal of the MAIN MIX. The INSERT connectors are
placed on the rear panel of the mixer and they have
the signal SEND on the JACK TIP and the signal
RETURN on the JACK RING (see CONNECTOR
CABLES).
4. C. ROOM OUTPUTS
Two unbalanced JACK connectors (+4dB): send out the
signal of the channel selected with the SOLO or (when
no SOLO button is pressed) the signals selected in the
C. ROOM SOURCE section. This output can be used
for monitoring or as an auxiliary bus.
5. ALT 3-4 OUTPUTS
Two unbalanced JACK connectors (+4dB): send out the
signal of the channel selected with the ALT 3-4 buttons.
This output can be used as an auxiliary bus.
6. DSP FOOTSWITCH - rd 122 fx only
Allows to connect a footswitch to turn on/off the built-in
Digital Effect Processor.
