Jumper Options
Changing Jumper Settings
To change a jumper setting, remove the ten screws secured to the top of the mixer. After
removing the top of the mixer, locate the jumper to be changed by referring to the drawing
on page 17. Jumpers are included from the factory in positions: JP1: 1-3, JP2: 2-4,
JP3: 1-3, JP4: 1-3, 2-4..
Warning: Disconnect AC Power before opening case.
Bar Graph Options
The mixerʼs meter can be configured to meter the output of either the main or auxiliary
bus. In addition, the bar graph can be configured to register either the peak or average
level of the audio signal.
JP2
The LED Bar Graph Output Meter can be set to register either the main or auxiliary
bus output audio signal. The choices are:
MAIN installed: The Bar Graph meters the main bus output. This is the factory default.
AUX installed: The Bar Graph meters the auxiliary bus output.
Note: The meter will operate only when a jumper is in one of these two positions.
JP3
The LED Bar Graph Output Meter can be set to register either the peak or average
level of the output audio signal. The choices are:
PEAK installed: The Bar Graph meter registers the peak level of the audio output.
AVG installed: The Bar Graph registers the average level of the audio output.
This is the factory default.
Note: The meter will operate only when a jumper is in one of these two positions.
Bus Routing Options
AUX In Jumpers: JP4
These jumpers determine the destination of the Auxiliary Input. The choices are:
MAIN installed: Auxiliary Input is routed to Main Output.
AUX installed: Auxiliary Input is routed to Auxiliary Output.
MAIN and AUX both installed: Auxiliary Input is routed to both Main and AUX outputs.
This is the factory default setting.
AUX Source Jumpers: JP1
These jumpers determine which of two gain controls are used to control the level of the
AUX output. The choices are:
INT installed: AUX output gain is controlled by the internal pot, “AUX Pregain Pot” R342
(see page 17 for location). The front panel AUX output volume knob continues to
independently control the gain of the headphone amplifier jack on the front panel. This
setting is typically used in a linking situation where the output from a mixer must remain
fixed, since JP1 makes the output of that mixer tamperproof (from the front panel).
With INT installed, the front panel AUX volume knob controls only the headphone level.
EXT installed: AUX output gain is controlled by AUX volume knob on front panel.
The 1/4-inch Headphone amp is also controlled by the AUX volume knob, but not
independently of the AUX output.
This is the Factory Default.
Note: Never install jumpers in both positions INT and EXT.
