General Description

Dedicated to the needs of the acoustic musician, the
AP 13 Acoustic Preamplifier is a full-featured package specifical-
ly suited for instruments with two pickups. The AP 13 provides
two signal processing paths: one optimized for piezo pickups and
one for microphone pickups. The piezo path features very high
input impedance for extended low bass response; while the mic
processing channel offers two choices of phantom power voltages
satisfing most electret condenser mic pickups. Additionally, ei-
ther channel accepts dynamic pickups or line-level outputs from
outboard preamps. A convenient front panel slide switch allows
choice of which pickup is wired to the tip or the sleeve of the
stereo ¼" input jack. Handy Pickup Gain Trim controls feature
large openings for quick changes using guitar picks, fingernails
or coins. And separate pickup Overload indicators make gain
set-up easy.
Each pickup signal path contains an Invert switch, an adjust-
able Low Cut filter, a 7-band graphic equalizer, a Pan control and
a separate Level amplifier, all logically arranged along the front
panel using smooth-acting oil-damped sliders for the ultimate in
convenience and graphical feedback. The Invert switch solves the

annoying (and too common) problem of what to do with pickups
wired out-of-phase. The sliding Low Cut filter helps eliminate
troublesome thumping, rumbling, rubbing and other unwanted
infrasonic frequencies. The graphic equalizers give you separate
timbre control over each individual pickup. The Pan and Level
controls mix both pickups into one smooth stereo signal ready to
drive the Send/Return Effects Loop, or the in-line Inserts. Two
pair of high-current cross-coupled balanced stereo line drivers,
with Mono switch, complete the processing chain. Choose be-
tween the stereo ¼" line-level outs for amplifier feed or the stereo
XLR mic-level outs for direct console patching, or use them both.
A powerful Headphone amplifier and Master Mute switch
allow private auditioning and practice. The Tuner Output lets
you leave your tuner attached for quick checks or changes during
performance. When an auxiliary output is necessary, the separate
Piezo Output with Level control perfectly satisfies the need.
The AP 13 Acoustic Preamplifer is all you ever dreamed of
for perfect control of your acoustic instrument (years of practice
not included).
