Functions
1. Mic gain control
The input sensitivityof the Mic (2) input is determined by the gain
control. With the gain control you are able to adjust the input-
sensitivity for an optimal match with the mixer’s internal operation
level. The high gain of this mixer is ideal when dealing with very low
input levels.
2. Mic input combo connector
Electronically balanced combo-type input for connecting low
impedance microphones. The input has extremely low noise and low
hum. When connecting a microphone make sure that the pin
assignment is correct. Always make sure to read the manual of the
microphone you want to connect. The combo- input is not suitable
for connecting an additional mixing console, FX- unit, etc. You have
to use the
line (17,20,37-40) inputs, when connecting this kind of
equipment.
Note: When connecting signal sources, please make sure the corresponding channel faders and the
master faders are at their minimum settings. Otherwise unpleasant plug-in noise can occur.
3/4/6. Equalizer section (hi/mid/low)
The microphone channel’s equalizer section allows shaping of the incoming audio signal. All input
channels are fitted with 3-band EQ. The
high (2) and low (1) shelving controls have their frequencies fixed
at 10 KHz and 100 Hz respectively. The mid (3) range control has a peaking response frequency at 1 KHz.
All 3 bands have up to 12dB cut and boost, with a centre detent. Turning an equalizer control to the right
amplifies the frequency range; turning to the left attenuates the signal. Minor changes to an equalizer
control usually produce the best results. Try to avoid excessive enhancement of the mid band.
5. Mic level control (Mic 1/2)
Controls the volume of the corresponding microphone channel.
7. PFL button
The PFL button (pre fade listening) is designed to route the
corresponding channel’s input to the headphone section,
independent of the individual channel’s volume fader setting. It is
possible to assign more than one channel simultaneous to the PFL
bus.
8. Channel gain control
Channel input level is determined by the gain control. With the gain
control you are able to adjust the line input-sensitivity for an optimal
match with the mixer’s internal operation level. The high gain of this
mixer is ideal when dealing with very low input levels.
9. Input selection switch (channel 1/2)
With this you are able to assign the line inputs or the phono inputs to
the according channel.
10. Peak LED
The peak LED shows peak levels in a channel’s incoming signal level. If the red peak LED frequently blinks
or constantly lights, the corresponding channel is likely to enter clipping and you have to reduce the
input’s amplification using the
gain (8) control. The peak LED lights at a level of 8 dB below clipping.
Make sure that the peak LED lights only briefly during dynamic peaks.
11. Input selection switch (channel 3/4)
With this you are able to assign two sets of line inputs to the according channel.
