9-Volt Battery
Lift the lid on top of the Pocket Blender and insert a fresh 9-Volt alkaline battery. Observe the correct
polarity. Battery life is an estimated 60 hours of continuous use.
9-Volt AC Adapter Input
Use only a well filtered and regulated 9-Volt AC adapter. We recommend a Fishman Model-910 or
Roland PSA series regulated AC Adapter. Use of an unregulated adapter will not only void the warranty,
but may damage the unit.
Input Jack
Plug in a TRS stereo cable here. The input will accept two separate signals via a stereo instrument cable.
(Tip = Transducer Channel, Ring = Microphone Channel)
input to avoid a loud pop through the speakers. When you plug in here the battery turns on. To save the
battery remember to unplug the input when you're not using the Pocket Blender.

HANNEL
Use the Microphone Channel for a mini-electret microphone (switch 9-Volt phantom on rear panel on) or
with a second pickup (9-Volt phantom off).
Volume Control
Normally set the volume for the microphone at around 12:00 (see Trim instructions below).
Bass And Treble
These shelving style tone controls provide basic equalization for the Microphone Channel. Set them at
12:00 for no cut or boost (flat).
Phase Switches
Prevent feedback and match up the pickup and microphone signals for a stronger amplified sound.
How to kill feedback in the Microphone Channel:
Adjust the Master volume level to 3:00 and turn the Transducer volume off (7:00).
Adjust the Microphone Channel volume to just below the threshold of feedback. Play your instrument and
toggle the Microphone Channel phase switch. Leave the switch where it feeds-back the least.
How to get the pickup in phase with the microphone:
After you perform the above step, raise the Transducer Channel volume until it is about the same level as
the Microphone. Play a sustained note or chord on your instrument and toggle the Transducer Channel
Phase switch. Leave the switch in the position that sounds strongest and feeds-back the least.
Once the pickup and Microphone are in Phase, make note of the relative position of the two switches.
They will be either in the same position, or one in and one out. To keep pickup/mic in phase, push both
switches anytime you adjust the overall polarity.
Engage the Mute switch before you plug into the
