Sound Performance Lab 9629 Manuel D’Utilisation

Switch off power of all units to be connected before you connect the Auto
Dynamic De-Esser.

The Auto Dynamic De-Esser is fitted with both XLR-connectors and TRS

stereo jacks for balanced operation, though the jacks may be used with
unbalanced connections simply by plugging in mono jack-plugs. The level
difference that normally occurs when a balanced input or output is used
unbalanced is automatically compensated for.

Should the need arise to use the XLR connectors in an unbalanced system,
pin 3 of the XLRs should be grounded. Inserting a mono jack also unbalances
the XLRs.

Both output stages operate in parallel, so it is possible to connect two diffe-
rent destination units simultaneously, for example to record to two different
media at the same time or split the output between a mixer and effects
processor. However, only one type of input (jack or XLR) should be
connected at a time – the Auto Dynamic De-Esser is not intended to be used
as a mixer!

To ensure optimal signal quality, SPL has developed a new hybrid-compo-
nent balanced input/output stage using all laser-trimmed resistors with a
tolerance of 0.01%. This approach has resulted in an exceptionally high
CCMR (common mode rejection): 100dB at 1kHz and 80dB at 10kHz. As a
precaution, before connecting the Auto Dynamic De-Esser switch off power
of the unit and of all units to be connected.
