Congratulations on purchasing a high quality SOUNDMASTER Mixing desk
The Soundmaster range of P.A. Mixers are available in three sizes:
PAM 8-2 Eight input channels and one output / monitor module
PAM 12-2 Twelve input channels and one output / monitor module
PAM 16-2 Sixteen input channels and one output / monitor module
The mains lead supplied with this equipment should be wired as follows:
The BROWN wire should be connected to the LIVE terminal
The BLUE wire should be connected to the NEUTRAL terminal
The GREEN / YELLOW wire must be connected to the EARTH terminal
THIS UNIT MUST BE CONNECTED TO EARTH AT ALL TIMES -- FAILURE TO DO SO COULD
BE FATAL.
Input Channel Facilities
Input Connectors
Each channel has two input connectors. The XLR type connector is for a low
impedance balanced microphone, the 1/4" jack socket is for high level or line
inputs such as the output of a guitar, keyboard or tape recorder.
Gain Control
The gain control adjusts the input sensitivity of the channel to match the
output of the microphone. Adjust this control so that loudest peaks of signal
make the peak LED light briefly.
Peak LED
The Peak LED indicates when the input is approaching distortion. In normal use
the LED should not be illuminated, occasional peaks indicate that the signal
is 10 dB above its normal operating level, but it is not distorted. If the LED
is continuously illuminated the input is overloaded and the Gain control
should be reduced.
EQ. (Equalisation)
The Treble, Bass and middle controls (usually known as EQ) are provided to
adjust the sound or to correct for deficiencies in the microphone performance.
The centre position of these controls allows the signal to pass through this
section without adding or subtracting to the sound. Rotating these controls
will add or subtract from the signal at the respective band of frequencies.
Care needs to be exercised when using these controls because excessive amounts
of boost may exceed the mixer headroom (+20dB) so the gain control may need
to be reduced accordingly.
AUX 1 & AUX 2
The Auxiliary send controls set the amount of signal which is sent to the
foldback or the effects. These send signals are mixed and then sent to the Aux
outputs. Aux 1 is pre fade and is usually used for foldback, Aux 2 is post
fade and is usually used for the effects send.
Pan
The Pan control sets the stereo image (it pans between left and right
speaker).
PFL
The signal can be monitored on headphones before it is fed to the outputs by
the fader (Pre Fade Listen) Press the PFL switch and the LED will be
illuminated to indicate that the channel PFL has been selected. This operation
does not affect the signal output. This facility can also be used to monitor
or set the correct output level from the channel. The PFL is a full mix buss
so several channels can be monitored at the same time without interaction.
Fader
The level that the signal is fed to the main mixing buss is set by the fader.
During a performance the faders will be adjusted to alter the sound,
increasing or reducing differing parts of the show. The Fader is calibrated
in 5dB divisions and the line indicates the 20dB headroom. If the output of
the mixer is above 0dB when the fader is set to the start of the 20dB line
then distortion will be present at the output.
Output Facilities
Master Output
The two Faders control the signal level which is fed to the power amplifiers,
the output level is indicated by the two bargraph meters. The yellow LED is
0dB, the most common input for power amplifiers and tape recorders. The stereo
outputs are available on two 1/4" jack sockets.
Aux Sends and Return
The output from the Aux mixing busses is available via the two 1/4" jack
sockets. The level is 0dB and is the same as the stereo outputs. The aux
return is fed into the 1/4" jack socket. This input is similar in facilities
provided by the input channels, gain, Eq, Pan and the channel fader being used
in the same way.
Monitoring
The stereo output from the mixer can be monitored on the headphone amplifier,
the monitor level is set with the volume control. The PFL is fed to the
headphone amplifier when the PFL switch is operated and this is indicated by
the PFL LED being illuminated. When the monitoring is fed from the PFL buss
the right hand bargraph displays the level on the PFL while the left hand
bargraph displays the output signal. This facility is used to set or monitor
the level of the signal on each channel.
Power supply
The built in power supply has a 20mm 1A quick blow fuse. In the event of the
fuse blowing it should be replaced by one of the same type. The unit requires
a mains supply of 220v to 240v, 50 or 60Hz.
THIS UNIT MUST BE CONNECTED TO EARTH AT ALL TIMES -- FAILURE TO DO SO COULD
BE FATAL.
