M500 OPERATORS MANUAL Ch 6 - 5
SIDE CHAIN INSERT JACK
The side chain insert jack, (called S/C jack), on the rear panel of the M500 has several positions
in the control circuit dependent on the Effect assignment.
EFFECT MODULE SIDE CHAIN JACK USE
None assigned S/C Jack has no use, although input signal is present at the 'send'
contact.
GATE (direct S/C Jack has input signal for GATE detection.
source) Breaking the jack will stop the GATE operating.
GATE (internal S/C Jack has input signal post filter for GATE detection.
filter) Breaking the jack stops the GATE operating.
GATE (external S/C Jack has key input signal post filter for GATE detection.
filter) Breaking the jack stops the GATE operating.
EXPAND S/C Jack has input signal for EXPANDER detection.
Breaking the jack will stop the EXPANDER operating.
COMPRESS S/C Jack has input signal for COMPRESS detection.
Breaking the jack will stop the COMPRESSOR operating.
LIMIT S/C Jack has input signal for LIMIT detection.
Breaking the jack will stop the LIMITER operating.
De-Ess S/C Jack has no use, although input signal is present at the 'send'
contact. Breaking the jack has no effect.
Pan S/C Jack is in signal path of the PAN audio trigger and the PAN output
display meters.
Fader S/C Jack is in signal path of the FADE timer trigger and FADE output
display meters. Either side chain will trigger the FADE timer.
For other combinations of Effects the S/C jack signal route description can be assumed to be
similar to the following examples:-
GATE & De-Ess
S/C Jack is used for the GATE only. Of course if the side-chain-jack is
broken then no signal will be output. So it could be said that the S/C jack
does effect both the assigned modules.
EXPAND, All modules are routed through the side chain.
COMPRESS &
LIMIT
When LINK INs is set to On the De-Ess, Comp, EXPAND, LIMIT Fx signals passing
through the S/C jack are averaged. Hence, when a side chain insert is necessary
both S/C jack insert points must be used, otherwise only a maximum change of
6dB signal level will be noticed.
INTERNAL BATTERY
Inside the M500 is a Nickel-Cadmium battery. This is kept charged whenever power is applied to
the unit. It is expected to last a minimum of five years, but extreme power conditions can shorten
this period. Symptoms of the battery failing are varied but will manifest itself as incorrect meter
level displays, 'ERROR 4' messages and irregular threshold response, especially on the GATE
Effect. Battery failure can aslo corrupt the USER PATCH titles and RECORDED ENVELOPES
preventing them from loading.
The battery is NOT a user-serviceable component and no attempt should be made to change this.
Furthermore, any tampering with the battery will destroy the internal calibrations and User Patch
memories. If the battery is suspected of failing please return the M500 to your DRAWMER dealer
for service.
