PowerPre 500 Module
FEATURE SET
1. GAIN VU - 10 Segment LED bar provides visual peak signal
status by simulating the natural ballistics of a VU meter. Single
fl oating LED with peak hold lowers power demand for greater
effi ciency.
2. -15dB PAD - Expands the PowerPre’s capabilities by allowing
ultra hot signals from devices such as digital keyboards or
electronic drums to be interfaced without distortion.
3. 180º - Polarity reverse used to phase-align two microphones or
as a creative element when recording.
4. FILTER - 100Hz high pass fi lter removes low frequencies to
help eliminate excessive bass that can cause rumble. This
also helps clean up the recorded track by reducing ‘mud’.
Particularly useful when layering acoustic instruments.
5. OUTPUT - Adjustable gain control features dual taper
Accustate™ drive circuit that keeps background noise down at
all levels. Up to 55dB of gain adapts to all types of microphones
including condenser, dynamic and low output ribbon.
6. VOX: 3-position voicing switch lets you change the tonal
character of the preamp to suit. The linear setting delivers ‘true
clinical’ response for classical instruments; the breath position
adds ‘air and clarity’ to help vocals cut through the mix; punch
adds warmth to the bottom end to fatten up a track.
7. 48V - Phantom power for condenser microphone is equipped
with power-on LED and recessed to prevent accidental use that
could damage ribbon microphones.
8. MIC INPUT - XLR female connector is conveniently located on
the front panel and placed at the bottom to keep the cable out
of the way. Wired pin-2 hot following AES standard.
9. OMNIPORT - Rear mounted ¼” connector designated as an
instrument input to allow guitar and bass to be recorded direct.
Available when used with the Workhorse.
10. XLR Output - Equipped with Hammond broadcast transformer
for smooth, warm response while being able to handle extreme
transients without choking.
11. GROUND LIFT (access at rear of module) - Disconnects pin-1
ground on the XLR input to eliminate ground loops. This special
feature should only be used when interfacing the PowerPre
with electrically powered instruments like a keyboard.

Important!:
Phantom power will be interrupted if the ground lift switch is set to the “LIFT” position. If your
condenser mic is not working, check to make sure this switch is in it’s normal “GND” position (see photo).
Note that the front panel LED for 48V phantom power will still illuminate when set to “LIFT”.
