2.2 Input Stereo
Since most features – AUX faders, 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.
16 - MIC
Different from the products of many other manufacturers, the stereo input channels of the PowerMa-
te, like their monaural counterparts, incorporate extensive circuitry and electronically balanced XLR-
type connectors for the connection of low impedance microphones. No matter if your setup is more
microphone-oriented or you have more line level sound sources to connect, you can always use the
full amount of input channels, provided by your PowerMate. Dependable on its setting, the high-quality
MIC input in the stereo channel is capable of handling levels between -60 dBu and +11 dBu. Low-level
circuitry architecture and phantom power (+48 V) ability of this XLR-type input are mainly aimed at the
connection of microphones, making it not necessarily suitable for connecting Line level appliances,
like mixers, effects units, etc. Please use the provided LINE inputs to connect those sound sources.
General functions and usage of MIC inputs were already discussed in detail for monaural channels.
17 - 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 you can use monaural or stereo phone plugs, which are in ac-
cordance to the diagram below. If the external appliance is equipped with a balanced output stage,
using balanced cables and plugs is preferable, since this type of connection provides improved shield-
ing 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.
