To use, set the on/off switch to "on" and plug in a stereo Y cable with the two legs of the Y plugged into two muted channels of any sort
of outboard gear. Plugging in a stereo cable automatically routes a live pickup signal to the top and a live mic signal to the ring contacts
of the stereo strapjack while disabling all onboard controls. Any blending, contouring and controlling of each output must now be done
outboard.
Note: The stereo sensing circuit may not work properly if the mic (ring) output of the Duet II is plugged into any outboard gear, such as
compressors or EQs, that have DC-coupled inputs and an input impedance lower than 47k. This type of input is uncommon in musical
instrument and recording studio gear, but low Z, DC-coupled inputs do exist. The symptom of this condition will be distortion in the
pickup (tip) channel. If you hear distortion in the pickup channel, try unplugging the mic from its channel. If the distortion on the pickup
channel disappears, the mic is plugged into a low Z, DC-coupled input. The remedy for this is to not use this piece of outboard
equipment.
