Instructions and installation
✔ ✔
✔ ✔
✔ Connecting the mixer to the mains supply.
Before connecting the amplifier to the mains socket, always make certain that:
- the electric system and mains socket have an adequate grounding, compatible with the safety norms (if you’re
uncertain, consult specialized personnel);
- the mains voltage corresponds to that shown on the rear of the unit (an allowance of up to ±10% is accepted);
- the power cord is not damaged and has no bare wires;
- the on/off switch is in the OFF position.
Make sure the mixer is also off before disconnecting the power cord from the mains socket. It is best to lower (or better still
close) the output levels and switch off any amplifiers connected to the line output of the mixer before switching the mixer on
or off: this avoids annoying and sometimes dangerous (particularly for the speaker cabinets) signal peaks.
✔ ✔
✔ ✔
✔ Connection and prevention or identification of possible disturbances.
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. When connecting the other
components of your sound system, watch out for the so-called “ground loops”, which could cause hum and jeopardize the mixer’s
excellent Signal-to-Noise and low distortion characteristics. The best way (even if not always feasible) to avoid ground loops is to
connect the electric ground of all the equipment to a single central point (the so-called “star” system). In this case, the central point
in sound systems is the mixer.
✔ ✔
✔ ✔
✔ Protection and maintenance.
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. Take care of the connector cables, always holding them by the connectors and avoiding pulling the wire
and avoid knots and twists when coiling them: this gives the advantage of increasing their life and reliability, which is always
to your advantage. Periodically check that your cables are in good condition and are correctly wired and that all their contacts
are perfect: a great number of problems (faulty contacts, ground hum, discharges, etc.) are caused entirely by using unsuitable
or faulty cables.
Avoid exposing the mixer to direct sun, strong heat, intense vibrations, very dusty or damp surroundings, or even worse, rain:
this will avoid eventual malfunction, deterioration or even electric shocks and fires. Any dust on the mixer should be removed
using a soft dry cloth or a brush; never use alcohol, acetone or solvents.
✔ ✔
✔ ✔
✔ In the event of breakdown
All user-adjustable parts are external and easily accessible. Never open the amplifier: you could run the risk of serious electric
shocks. In the event of breakdown, contact the nearest GENERALMUSIC/LEM Assistance Centre
✔ ✔
✔ ✔
✔ Conservation of documents and packing.
Keep this manual for future consultation. On this subject, remember a golden rule: equipment always gets a better price on
the secondhand market if it has all its original documentation and packing as well as being well kept.

MONO input channel
MIC INPUT
Balanced XLR connector: this input is for use with microphones,
but can also accept a wide range of balanced or unbalanced low
impedance signals. Do not connect keyboards, recorders or other
equipment with a line signal, as the signal level would be too high
and probably distorted.
LINE INPUT
Balanced JACK connector: can receive balanced or unbalanced
high-impedance signals from equipment with a high-level output
(all instruments excluding microphones). Do not connect a
microphone to this input: the signal would not be sufficiently
amplified and will probably be poor and disturbed.
CHANNEL INSERT
STEREO JACK connector: allows to use an external device
(equalizer, compressor, etc.) to process the signal of the channels
1, 2 and 4. The INSERT connectors have the signal SEND on
the JACK TIP and the signal RETURN on the JACK RING (see
CONNECTOR CABLES).
LO-CUT
HI-PASS filter: allows to reduce the frequencies below 75 Hz with
a 18 dB / Oct. slope. Thanks to this filter it’s possible to eliminate
unwanted subsonic frequencies, like, for examples the
microphones rumble due to the stage resonance.
GAIN
Gain control: regulates the amplification of external signals
(microphones, instruments, etc.) fed into the channel.
HIGH
HIGH frequency control: gives a 15dB boost or cut at 12 kHz
with a “SHELVING” curve.
MID
MID frequency control: gives 15dB boost or cut from 100 Hz
to 8 kHz (channels 1-3) or at 2.5 kHz (channels 4-6) with a
“PEAKING” curve.
LOW
LOW frequency control: gives 15dB boost or cut at 80Hz with
a “SHELVING” curve.
MONO input channel

4
MONO input channel
MONITOR
Control for the MONITOR send level.
The MONITOR send is PRE-FADER: this means than the signal
sent to the MONITOR is taken before the control of the channel
FADER, allowing a completely independent mix for the monitoring
respect to the main mix.
AUX1 & AUX2/DSP
Control for the EFFECT sends level.
The AUX1 and AUX2/DSP sends are both POST-FADER: this
means than the signal is taken after the control of the channel
FADER and therefore its level is effected by the fader’s setting.
The AUX1 sends the signal to the AUX SEND 1. The AUX2/DSP
sends the signal both to the AUX SEND 2 and to the internal DSP.
PAN
Centre-dented Pan pot for controlling the signal’s pan:
regulates stereo “position” of the signal with respect to the main
L&R outputs. If PAN is turned completely to the LEFT, the signal
will only be sent to MIX LEFT, if it’s turned completely to the
RIGHT, the signal will only be sent to MIX RIGHT. At intermediate
settings, the signal is sent to both MIX LEFT and RIGHT, but in
different proportions.
PEAK
PEAK LED indicator: lights up when the input signal is near to
the CLIPPING point. This control is POST-GAIN, POST-INSERT
and POST-EQ and, therefore, reacts to the signal already
processed by the internal EQ and by external units. Set the GAIN
control in such a way that the PEAK LED do not light up or only
do so occasionally.
SOLO
Button for PRE-LISTENING function: allows the channel signal
to be selected for the listening thru the HEADPHONES outputs
and the visualization on the LED BARGRAPHS. According to the
position of the SOLO MODE button the listening and the
visualization can be PRE or POST-FADER.
LEVEL
Fader for controlling channel level: regulates the level of each
channel sent to the MIX L&R main outputs.

STEREO INPUT
Balanced JACK connectors: receive the STEREO LINE input signal on the channel
(0dB). Inserting a single JACK connector on the LEFT socket this channel can be
used as a MONO channel.
LEVEL
Gain control: regulates the amplification of the signal connected to the L&R inputs.
The selectable values are +4 and -10 dB.
BAL
Centre-dented control of the balance of the signal on the main outputs.
The BAL control has a balancing effect on the levels of the two LEFT & RIGHT parts
of the STEREO signal and works as follows:
• turning to the LEFT lowers the RIGHT signal level on MIX RIGHT;
• turning to the RIGHT lowers the LEFT signal on MIX LEFT.
NOTE: the remaining features of the STEREO channel are the same as in the MONO
channel.

GRAPHIC EQ
Nine mini-slider for the
GRAPHIC EQ control.
The GRAPHIC EQ can be
used to regulate the overall
mixer frequency response, in
order to control the tone of the
main sound system and/or the
recording. The nine mini-
sliders give 12dB boost or cut.

OUTPUT/SOLO LEVEL
12-LED BARGRAPHS.
Allows the visualization of the signal assigned to the HEADPHONES output by the SOLO buttons or by
the selection buttons (see point 28).
The LEDs are of three different colors:
• green = show the normal operative level of the signal (from -30 to +4 dB);
• yellow = show a high operative level of the signal (from +7 to +10 dB);
• red (CLIP) = show a too high signal level, near to the overload of the mixer output stage.
To ensure clean, distortion-free signals and to avoid damaging the components of your sound system,
try to avoid making the red LEDs lighting up repeatedly.
POWER LED
LED indicating when the mixer is switched on.
+48V LED
LED indicating when the +48V phantom power is switched
on: this LED lights up when the buttons on the connector panel
on the rear of the mixer are pressed.
PROTECT LED
Indicates the intervention of the built-in POWER AMP
protection system. The internal protection is activated to protect
the amplifier and the connected loudspeakers from damage due
to an electronic fault or improper usage. In this case, switch off
the mixer and check all the connections.

DSP
DSP
The SWING 14P is fitted with a built-in DSP, including
128 high-quality REVERB and DELAY effects able to
reproduce accurately different kinds of ambients and to
enrich not only the voice, but also any kind of instrument.
The 128 PRESETS can be selected by means of two
16-position encoders. The first encoder selects the
BANK, while the second one selects 8 DIFFERENT
PRESETS for each bank. A PEAK LED, which lights
up when the input signal is near to the CLIPPING point,
and an ON/OFF button are also available.
The following table includes the list and the main
parameters of the 128 PRESETS available in the
internal DSP.

Main fuse holder
In the event of breaking, always replace the fuse with same type and rating.
+48V
+48V Phantom power supply button: this button switches on the +48V power supply for all the MIC inputs
(XLR-F connector) of the MONO input channels and allows condenser microphones to be used on them.
When the PHANTOM power supply is switched on make certain that cables with BALANCED XLR
connectors are ALWAYS used to connect the microphones: this precaution is extremely important for
avoiding damage in the event of both condenser and normal (dynamic) microphones being used
simultaneously. Switch on the phantom power supply only after having connected the condenser
microphone to the input and only with the channel fader closed to avoid output signal peaks.
POWERED OUTPUTS
POWER AMP outputs: connect these outputs to the loudspeaker enclosures.
Be careful that the overall impedance of the speakers connected is not below 4 Ohms, because in this
case the amplifier could protect himself. Only use “power”cables (speaker enclosure cables), not “signal”
cables (screened cables used for instruments and microphones).
