SONOSAX SX-PR - Manual (Page 5)

Level meter selections
The slide switch to select VU or Peak metering is accessible after dismantling the left side pannel. Factory setting is always Peak metering.
Also accessible from the left side is the slide switch where you select whether or not the meter follows the headphone output (MONO/STEREO and L/R). Factory setting is always
master output metering.
Limiter level adjustment
The trimmers alowing the adjustment of the limiter action level are also on the left hand side available. Factory setting is +6dBu (corresponding to 0dB on the level meter).
Sensitivity of the Tape return input
The sensitivity of this input can be adjusted by the trimmers available on the right hand side of the module (it is necessary to dismantle the input modules). Factory setting is +6dBu.
Balance of the master outputs
The trimmers T3 (left channel) and T4 (right channel) alow a perfect adjustment of the balance. First dismantle the input modules. Switch on the internal oscillator and on a double
beam oscilloscope, with its inputs set on sumation, observe the signals on pin 2 and pin 3 (against ground) and adjust the balance.
CHARGING SWITCH
NiCd batteries can be charged providing the switch is set for it (ON). Some mixers may have a jumper instead of the switch which must be taken off to cancel the charging.
Attention: Do not charge dry cells. This may be dangerous and will damage your mixer in case the cells leak out
or explode. When using external power supply with this switch in charging mode always take out the
dry cells.
This slide switch (or jumper) is on the board below the battery housing. Unscrew the 4 cross slot screws on the bottom plate of the master module and very carefully pull out the battery
housing with the DC/DC converters. For security reasons, the factory setting is always " OFF ".
Very important:
These adjustments must be executed by a SONOSAX appointed Distributor or Dealer. Damage due to manipulations inside the unit cancels the
SONOSAX garantee liability.
