1. Introduction
Congratulations for having chosen the
rx 200
mixer!
To make the best use of the mixer, please read this
manual thoroughly before operating the equipment.

3. Instructions for use and installation
1. Protection and maintenance.
To avoid jeopardizing correct operation, it is best not
to position the mixer for long periods in exposed places
(damp, high temperature, etc.), in dusty environments
or those subject to strong vibrations. Do not force
knobs, switches or faders: they have been designed to
respond to a light touch and could be damaged if
treated with excessive force. In the event of breakdown,
do not open the mixer, but contact the nearest
GENERALMUSIC Service Centre.
2. Prevention of possible interference.
First of all, check that the mixer is installed in a place
free from industrial or RF (radio frequency) interference.
Avoid installing your equipment very near radio or TV
sets, mobile phones, etc., as these can cause noisy
interference.
3. Connections.
Before connecting the mixer to the mains socket, always
make certain that the electric system and mains socket
have an adequate grounding, compatible with the safety
norms. Be sure also that the mains voltage corresponds
to that shown on the rear of the unit (an allowance of
up to ±10% is accepted) and that the power cord is not
damaged and has no bare wires. It is best to lower (or
better still close) the output levels before switching the
mixer on or off: this avoids annoying and sometimes
dangerous (particularly for the speaker cabinets) signal
peaks.
4. Connector cables.
When connecting loudspeaker systems to the mixer’s
power outputs, make certain to always use only power
cables made up of just two wires with the same cross-
section: the use of signal cables could cause an
excessive loss of power. Check periodically that your
cables are in good condition, correctly wired and with
perfectly efficient contacts: in fact many problems and
drawbacks (false contacts, ground hum, crackles, etc.)
are caused by the use of unsuitable or damaged cables.
4. MONO input channel (pic. 1)
1. MIC INPUT
Balanced XLR: this input receives the MICROPHONE
signal on the channel and can accept a wide range of
balanced or unbalanced low impedance signals,
including the signal coming from condenser
microphones with +48V power supply (
see Rear panel
).
2. LINE INPUT
JACK: this input can receive high-impedance signals
from equipment with a LINE output.
3. GAIN
Gain control of the amplification of external signals fed
into the channel.
The range is: MIC = -10/-50 dB, LINE = +10/-30 dB.
4. HIGH
HIGH frequency control: gives a 15dB boost or cut at
12 kHz with a “SHELVING” curve.
5. MID
HI-MID frequency control: gives 15dB boost or cut from
at 2.5 kHz with a “PEAKING” curve.
6. LOW
LOW frequency control: gives 15dB boost or cut at 80Hz
with a “SHELVING” curve.
7. AUX1/DFX pre
The AUX1/DFX send is POST-FADER (this means than the
signal is taken after the control of the channel level) and it feeds
both the built-in DSP and the AUX 1 output. The AUX1/DFX
send can be used to add the channel’s signal some effect
coming from the internal DSP or from an external unit.
8. PAN
Centre-dented pot for controlling the signal’s pan.
9. PEAK
PEAK LED indicator: lights up when the input signal is
near to the CLIPPING point. In this case, reduce the
level of the input signal using the GAIN control.
10. LEVEL
Potentiometer for controlling channel level.
5. STEREO input channel (pic 2)
1. STEREO INPUT
JACK connector that receives the STEREO LINE input
signal on the channel. Inserting a single JACK
connector on the LEFT socket this channel can be used
as a MONO channel.
