SR Series EQ’s
ATTENTION: DO NOT USE BOTH THE BALANCED AND UNBALANCED
INPUT/OUTPUT JACKS TO A CHANNEL AT THE SAME TIME. Using more
than one connector at a time for the input/output pair can unbalance balanced
lines,cause phase cancellation,short a conductor to ground,or cause damage to
other equipment connected to the equalizer.
Maintenance and service
Other than keeping the unit clean and occasionally checking the connectors and
cables to the unit for integrity, there is no maintenance necessary for DOD
equalizers.
There are NO user serviceable parts inside the units. Opening the chassis will
void the warranty. All service and repair must be performed by the factory or
an authorized service center for the warranty to remain in service.
Should a problem arise with the equalizer,please contact your authorized DOD
Electronics dealer for return/repair procedures.
