Stereo Input L/Mono R; Gain Mic; Line Trim - Dynacord PowerMate 1000 Owner's Manual

INPUT/STEREO
Since most features of the stereo inputs are virtually identical to the ones of the monaural inputs,
we will not discuss their functioning in detail again. Thus, we only point out the differences and
ask you to refer to the analogous paragraphs in the first chapter of this owner's manual.
14. MIC
Like their monaural counterparts the stereo input channels of the PowerMate incorporate extensive
circuitry and electronically balanced XLR-type connectors for the
connection of low impedance microphones. A feature that often
enough is not supported on mixers from other manufacturers. 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. The
functioning principles were already discussed in detail in the
previous chapter.

15. STEREO INPUT L/MONO R

Electronically balanced inputs for the connection of musical instruments with stereo output, like
keyboards, 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
–20dBu and +30dBu. For the connection of external devices you can use monaural or stereo
phone plugs which are in accordance to the diagram below. If the external appliance is equipped
with a balanced output stage, you should preferably use balanced cables and plugs, since this
type of connection provides better 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. For further
information, please refer to the chapter "INPUT/MONO".

16. GAIN MIC

Rotary control to adjust the MIC inputs' sensitivity, providing the possibility to optimally match the
incoming signals with the mixer's internal operation level. The GAIN MIC control is only active for
the XLR-type connections of the stereo input channels.
Adjustment and functioning of these controls are identical to those of the monaural inputs.
CAUTION: The GAIN MIC control of an inactive microphone input should always be set to its
minimal marking. Otherwise the noise of the inactive input is added to the audio signal of the
corresponding LINE input, which could lead to unnecessary extra noise at the main output,
becoming clearly audible in program breaks.

17. LINE TRIM

These rotary controls are used to match the incoming line level signals with the operational level
of the PowerMate. The total adjustment range is 30dB. Unity gain – no amplification (0 dB) – is
achieved at the 0dB mark. The control offers a level reduction of the incoming signal by –20dB
and an amplification of +20dB. This range is wide enough to allow the connection of most
professional, semi professional, and even hi-fi sound sources.
For further details on how to adjust the LINE TRIM control, please refer to paragraph 4. GAIN.
If you use a keyboard as sound source on one of the stereo inputs, make sure that no split zones
or layers with channel separation are activated. Otherwise the stereo channel mapping will appear
like it is set on the keyboard and you will not have the opportunity to re-position the sound in the
overall stereo image, using the controls of the mixer. The better alternative to connect a keyboard
