FEATURES - MONO CHANNELS
1. GAIN
- The GAIN control is used to match the incoming signal level to the internal operating
level of the
MX 1822
. This ensures the best performance, reduces noise and avoids distortion. The
MIC GAIN range is 10 to 60dB.
2. Hi
- The HI control cuts or boosts the high frequenc (12kHz). In the centre (12 o’clock) position,
the sound is unaffected.
3. MID
- MID consists of two controls: the upper one adsust the frequency (250Hz ÷ 6kHz); the
lower one cuts on boosts the selected frequency.
4. LO
- The LO control operates in the same way as the HI control except that it affects the low
frequencies (60Hz).
5. AUX A
- The AUX A control is assigned POST-FADER for use with external effects units such as
delays or reverbs. First the effects unit has to be connected to the
MX 1822
. The socket marked
AUX A POST on the
MX 1822
connects to the input of the effects unit. The output of the effects
unit is then connected to the AUX input 39 or an unused channel. As the AUX control is turned
clockwise, the sound from that channel is routed, via the AUX A POST control 23 , through to the
AUX A POST socket and out to the effects unit The effected or treated sound comes out of the
effects unit and back to the
MX 1822
.
Increasing the level of Aux Input or the channel FADER will now MIX the treated sound with the
original. This is called an effects loop as the sound has been taken out to an effect, returned and
joined with the original sound.
(To change the signal source - see Options section, page 23).
6. AUX B
- The AUX B control can be used when an additional or different MIX of sound is required
(such as using stage monitor speakers).
As the AUX B control is turned clockwise more of the sound in the channel is routed, via the AUX
B PRE control 24 , to the AUX B PRE socket on the rear panel. This would then be connected to an
amplifier to power the stage monitor speakers (or a headphone system).
AUX 1 and AUX 2 controls are very similar except that adjusting the channel FADER does not
affect the sound at the AUX 2. Musicians listening to the sound from the AUX 2 do not want it
changing when a channel FADER is adjusted. The opposite is required when an effects loop is
used, the effect needs to change with the position of the channel FADER. This keeps the blend of
original and treated signal constant. (To change the signal source - see Options section, page)
7. PAN
- Adjusts the position of the channel signal between the left or right output channel.
8. PEAK
- The PEAK LED Indicates that the channel signal is approaching its maximum level. If the
Peak LED remains lit, reduce the channel GAIN control setting until the LED sometimes flashes
on signal peaks only.
9. PFL
- Depressing the PFL button allows the selected channel (or channels) to be monitored
via the headphone output. When the PFL button is activated the PEAK LED stays fully illuminated
and the level is also shown on the the MAIN MIX bargraph meters.
10. FADER
- The FADER adjusts the level from the channel to the MAIN output. The FADER
acts as a volume control for each channel. They join all the various sounds together creating
a blend or ‘MIX’ of sounds. The Faders make small adjustments easy as well as giving a visual
representation of sound levels. In use, aim to set the FADER at the 0dB position. It can then be
raised or lowered to adjust the sound (MIX).
