1) INTERNAL MICROPHONE AND PICKUP

Pickup goes to Tip, microphone goes to Ring. 

Pickup and microphone signals are sent through a stereo 
instrument cable to the STEREO IN jack. 

Pickup signal is controlled by TRANSDUCER Channel.

Microphone signal is controlled by MICROPHONE Channel.

The Phantom Power should be turned ON (switch pushed OUT).

NOTE: If your instrument has an onboard battery, and you want to route microphone
and pickup signals through a stereo instrument cable, you may need to install a
Fishman SMART SWITCH for the system to operate. 

(See Page 22)

2) PICKUP ALONE

Single pickup is sent through a mono instrument cable to the 
STEREO IN jack.  

The signal is controlled by the TRANSDUCER Channel. 

Under battery power, turn the Phantom Power OFF (switch pushed IN)
to save battery life. 

3) MINI-MIC ALONE

Microphone signal is sent through a mono instrument cable to the 
AUX / MIC IN jack. 

The signal is controlled by the MICROPHONE Channel.

The Phantom Power is ON (switch is OUT).

NOTE: Under battery power, the STEREO IN jack must be plugged in 
to turn on the BLENDER.
