2.2 Input Stereo

Since most features – AUX/MON controls and channel faders – of the STEREO INPUTS are virtually
identical to the ones of the MONO INPUTS we will not discuss their functioning in detail again. Thus,
in the following we only point out the differences and like to ask you to refer to the analogous para-
graphs within this owner's manual describing the mono inputs.
HINT: The stereo inputs 5-6 and 7-8 are designed as so-called Super Channels. This means a MIC
and LINE input is available at this stereo inputs, like in the mono inputs. So, depending on
the application, the Super Channels can be used for a mono signal or a stereo signal of the
DIGITAL AUDIO INTERFACE (USB).
14 - STEREO INPUT L/MONO R
Electronically balanced inputs for the connection of musical instruments with stereo output, like key-
boards, drum machines, E-guitars and E-basses with an active output as well as all other equivalent
sound sources with high level outputs, like additional mixing consoles, FX units, CD players, etc. The
stereo LINE input is meant for balanced or unbalanced sound sources with levels between -20 dBu and
+30 dBu.
Using phone plugs
For the connection of external devices to inputs 9-10 or 11-12 you can use monaural or stereo phone
plugs, which are in accordance to the diagram below. If the external appliance is equipped with a bal-
anced output stage, using balanced cables and plugs is preferable, since this type of connection pro-
vides improved shielding against HF induction and external noise.
In case you want to connect a monaural sound source to a stereo input channel, you just have to plug
it into the L/MONO input. The signal gets internally routed to both channels.
Using RCA plugs
The RCA inputs CD 1-2 and CD 3-4 are connected in parallel to the phone inputs LINE 9-10 or LINE 11-
12. Do not connect signal sources to phone and RCA inputs at the same time.
Using the DIGITAL AUDIO INTERFACE (USB)
When using the DIGITAL AUDIO INTERFACE two stereo signals are available at USB 1-2 (input 5-6) or
USB 3-4 (input 7-8). Do not connect signal sources to the MIC or LINE of this stereo inputs when using
the DIGITAL AUDIO INTERFACE for playback. See page 15 for more details about the DIGITAL AUDIO
INTERFACE.
15 - TRIM LINE CD
These rotary controls are for matching the incoming line level signals (phone or RCA) to the operating
level of the CMS. The total adjustment range is 30 dB. Unity gain – no amplification (0 dB) – is
