CAUTION

Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

The Fixed connector outputs audio at a fixed level and is unaffected by changes made via the front panel Volume/Adjust knob. The Variable connector outputs audio that can be attenuated by turning the Volume knob. These preamp outputs can be set for mono or stereo output via the front panel menu or the control software.

9Effects connectors (Send, Return) — These two 3.5 mm, 3-pole captive screw connectors allow the selected audio signal to be looped through an optional recording device or equalizer before being sent to the main Audio Output ( 11 ) (preamp outputs) or the amplified audio output ( 7 or 8 ).

We recommend using shielded cables no longer than 10 feet (3 meters). These connectors should be wired as shown at right.
