INPUT MONO
3. INSERT
Stereo phone jack with breaker function. The low impedance output is assigned to the tip
(send) and the high impedance input (return) is assigned to the ring (body). This jack allows
the connection of external compressors, limiters, EQs, de-noisers, etc. into the correspond-
ing channel's signal path. The insertion point is post gain controls, Lo-Cut fi lters, and voic-
ing stage and pre sound shaping section and faders. You have to use a stereo phone plug
– according to the following diagram – in case you intend to use this jack as a true insert bus.
If you want to use this socket as a DIRECT OUT (Pre EQ), the stereo phone plug's tip and ring
have to be short circuited, so that the audio signal is not interrupted. If you are using a mon-
aural phone plug instead, you will get a DIRECT OUT with breaker function – the signal fl ow
within the channel is interrupted.
4. GAIN
Rotary control to adjust the MIC/LINE inputs' sensitivity. These controls let you optimally adjust
the incoming signals to the mixer's internal operation level. Cautious adjusting offers the ben-
efi ts of an improved S/N-ration and provides you with the full bandwidth of the PowerMate's out-
standing sound capabilities. On the XLR-type connectors an amplifi cation of +10dB is achieved
when the control is set all the way to the left and +60dB when the control is set all the way to the
right. Especially when dealing with very low input levels, like they occur during vocal recordings
or when the sound source is located in a distance, the high gain is extremely profi table. Using
the LINE-input, the signal is generally attenuated by –20 dB. The total adjustment range of 50dB
stays the same. The LINE-input's unity gain – no amplifi cation (0 dB) – is achieved at the 20dB
mark.The following is meant as a short note for your assistance on how to determine the right
input level:
Note on how to adjust the input level:
1. Set the gain control and the corresponding channel fader to their lowest setting.
2. Connect the desired sound source (microphone, musical instrument, etc.) to the MIC or
LINE input.
3. Play the sound source at its highest volume – respectively sing or speak as loud as
possible directly into the microphone.
4. While you are playing the sound source or singing into the microphone, adjust the input
level using the gain control, so that during the loudest passages the PEAK LED is just
not lit, but the SIGNAL - LED lights constantly.
This is the basic channel setting, leaving you with at least 6dB of headroom. Which means,
you have at least a range of 6dB before signal clipping. In case you intend to make further
adjustments to the channel's EQ setting, you should perform the steps 3. and 4. again
afterwards, since changes in the sound shaping section also infl uence the channel's overall
level.
5. LO CUT 80 Hz
When the LO CUT switch is engaged, frequen-
cies below 80 Hz are attenuated (18dB octave).
In most cases using the LO CUT fi lter with mi-
crophone channels is a good advice, since it ef-
fi ciently surpresses popping sounds and rumbling
noise. The only exceptions are kick drum and
acoustic bass.
