LINE IN

Each mono input also features a balanced line input on a ¼" connector.
Unbalanced devices (mono connectors) can also be connected to these inputs.
◊ Please remember that you can only use either the microphone
or the line input of a channel at any one time. You can never use
both simultaneously!
INSERT
The INSERT connector is input and output at the same time. This allows you
to insert external signal processors (compressors, gate, etc.) in the channel.
The signal retrieval occurs after the TRIM and is practically a diversion of
the signal. The input signal of the connected signal processor is diverted,
processed and led back to the channel for further processing.

TRIM

Use the TRIM control to adjust the input gain. This control should always be
turned fully counterclockwise whenever you connect or disconnect a signal
source to one of the inputs.
The scale has 2 different value ranges: the first value range (+10 to +60 dB)
refers to the MIC input and shows the amplification for the signals fed in there.
The second value range (+10 to -40 dBu) refers to the line input and shows
its sensitivity. The settings for equipment with standard line-level signals
(-10 dBV or +4 dBu) look like this: While the TRIM control is turned all the way
down, connect your equipment. Set the TRIM control to the external devices'
standard output level. If that unit has an output signal level display, it should
show 0 dB during signal peaks. For +4 dBu, turn up TRIM slightly, for -10 dBV a
bit more. Tweaking is done using the CLIP LED.
HIGH/LOW
All mono input channels include a 3-band equalizer. All bands provide boost
or cut of up to 15 dB. In the central position, the equalizer is inactive.
The upper (HIGH) and the lower band (LOW) are shelving filters that increase
or decrease all frequencies above or below their cut-off frequency. The cut-off
frequencies of the upper and lower band are 12 kHz and 80 Hz respectively.
MON/FX
FX send buses (or AUX send buses) enable you to extract signals from one or
more channels and collect these on a bus. You can retrieve the signal at the send
connector to direct it to an external effects device, for example. The AUX return
input is used as the return path. The send buses of the RX1202FX are mono buses.
As the name suggests, the FX sends of the EURORACK mixing consoles are
intended to drive effects devices (reverb, delay, etc.) and are therefore configured
post-fader. This means that the mix between dry signal and effect remains at
the level determined by the channel's aux send, irrespective of the channel fader
setting. If this were not the case, the effects signal of the channel would remain
audible even when the fader is lowered to zero.
In the RX1202FX, the FX send is routed directly to the built-in effects processor.
To make sure that the effects processor receives an input signal, you shouldn't
turn this control all the way to the left (-∞).
The MON path—as the name already implies—is meant to be used as monitor
signal path. For this application, it is important that the controller works as
pre-fader, which means it does not rely on the fader position. For this reason the
AUX send path is unsuitable for the connection to effects devices. By using the
MON controller, you can produce a mono mix of individual signals that can be
routed over the MON plug, located on the backside, to a headphones amplifier
(e.g. MINIAMP AMP800) or a power amplifier for monitoring.
PAN
The PAN control determines the position of the channel signal within the
stereo image. This control features a constant-power characteristic, which means
the signal is always maintained at a constant level, irrespective of position in
the stereo panorama.
CLIP
The CLIP LEDs of the mono channels illuminate when the input signal is driven
too high, which could cause distortion. If this happens, use the TRIM control to
reduce the preamp level until the LED does not light anymore.
Channel fader
The channel fader determines the level of the channel signal in the Main Mix.
Caution: The channel fader needs to be open so that the effects
◊
processor receives a signal from this channel because the FX bus
to the effects processor is switched to post-fader!

2.2 Stereo channels

Fig. 2.2: Connectors and controls on the stereo channels
LINE IN
Each stereo channel has two balanced line level inputs on ¼" connectors
for left and right channels. If only the connector marked "L" (left) is used,
the channel operates in mono. The stereo channels are designed to handle
typical line level signals. Both inputs will also accept unbalanced connectors.
