Preparing Your Instrument
Before you begin using your PowerMix, you need to have the magnetic and Powerbridge pickups in place on your guitar.
Wire the guitar to a stereo output jack as follows:
1-Route the magnetic pickup's signal to the TIP terminal. 2-Route the magnetic pickup's ground to the SLEEVE terminal. 3-Route the Powerbridge signal to the RING terminal. 4-Route the Powerbridge ground to the SLEEVE terminal.

NOTE: If you decide to wire the Powerbridge directly to the output jack (no instrument-mounted volume control for Powerbridge) you must wire a 5 Megohm resistor between the Ring and Sleeve terminals on the instrument's output jack.

Functions
BATTERY POWER
Make note of the following when using the PowerMix under battery power. The PowerMix has no on/off switch. Under battery power, the PowerMix is
turned on when the Mix Output jack is plugged in. To avoid excessive battery drain, unplug the Mix Output jack when the unit
is not in use (battery life is an estimated 150 hours, continuous use).
BATTERY COMPARTMENT
To install the battery, move the latch on the battery compartment in the direction of the printed arrow and pull the latch toward you. Once the compartment pivots out, pop open the little hinged door at the end of the compartment and insert a fresh 9V alkaline batter y. Note that the door will not close unless the correct battery polarity has been observed.
AC ADAPTER INPUT
USE ONLY a FISHMAN model 910-R or a Roland PSA series Regulated AC Adapter. Using an unregulated power supply will void the warranty and may damage the unit.
INPUT JACKS
The two Input jacks are designed to accept separate magnetic and piezo signals via a single stereo cable or a stereo “Y” cable.
The Mag / Stereo Input jack is a dual function input that will operate in either stereo TRS, or mono TS modes. The Tip connection of this jack receives the magnetic pickup signal from your guitar. The Ring connection of this jack can receive the piezo signal from your Powerbridge.
The Piezo Input jack is a mono input that receives the piezo signal from your Powerbridge.

PowerMix
NOTE: If you route two signals through the Mag / Stereo Input jack and plug a third signal into the Piezo Input jack, the signal that normally appears at the Ring of the Mag / Stereo Input jack will be replaced (overridden) by the signal appearing at the Piezo Input jack.
MIX OUTPUT JACK
A combination of buffered magnetic pickup and Powerbridge signals appear at this instrument level output.
PHASE SWITCH
If you experience a volume loss when combining the Powerbridge with the guitar's magnetic pickups, flip this switch to correct the phase relationship between the two.
LOW BATTERY INDICATOR
When plugging into the Mix Output jack, the Low battery LED will flash momentarily, indicating that the power is on. When the Low Battery LED stays on with the jack plugged in, it's time to change the battery.
VOLUME CONTROL
This affects the piezo volume only.
BASS AND TREBLE CONTROLS
These are shelving style boost/cut tone controls. These affect only the piezo pickup.
MIDRANGE CONTROL
This is a resonance style boost/cut tone control. It affects only the piezo signal.

Suggested Signal Routing Options
STEREO CABLE OPERATION
Magnetic and piezo signals from your instrument are routed through a stereo instrument cable to the Mag/Stereo Input jack on the PowerMix. The Tip signal (magnetic) goes to the magnetic input stage.The Ring signal (piezo) goes to the piezo input stage. In this case, the Piezo Input jack is unused.
9
PowerMix
STEREO Y CABLE OPERATION
Magnetic and piezo signals from your instrument are routed through a stereo Y cable. The magnetic pickup signal goes to the Mag/Stereo Input on the PowerMix. The piezo pickup signal goes to the Piezo Input on the PowerMix.
