First of all, thank you for purchasing what we feel is the finest acoustic
guitar pickup system available today. As you use your Amulet M, we're
quite sure you'll feel the same way.

The heart of the Amulet M is the Acoustic Lens™ pickups. Our Acoustic
Lens pickups deliver crispness and accuracy, coupled with incredible
warmth and presence. The Amulet M’s preamp perfectly complements
this incredible transducer. Super-wide dynamic range, low distortion and
low noise were the primary design goals behind the Amulet M preamp.
Dual pickups allow you to adjust the bass and treble balance of your
guitar without using any EQ whatsoever. The Amulet M system lets you
hear your acoustic guitar as you've never heard it before.

The on-board Dual Mono preamp is designed to perfectly complement
the Acoustic Lens' unique requirements and to amplify the low level
signals from the pickups as soon as possible. The signal that leaves your
guitar through the endpin jack is high level, low impedance, and most of
all, high quality. Power is provided by an on-board 9-volt battery with
more than 100 hours of battery life available. The output signal
presented to your mixer or power amp is the true sound of your guitar, in
microscopic wondrous detail. From here, the signal can be routed to a
mixer, effect unit or power amplifier, and then to a high quality speaker
system.

Our goal at Trance Audio is to further state-of-the-art, acoustic guitar
music. The Amulet M series provides the true sound of your acoustic
guitar and is designed to interface easily with any audio device.

The Amulet M™ consists of:

• Acoustic Lens™ Transducers (pair)

• Dual Mono Preamp/Endpin (installed inside the guitar)

• Battery bag with Battery clip

The Amulet M-V™ adds:

• Soundhole-mounted Volume Control and battery indicator

(with cable)

The Amulet M-VT™ adds:

• Soundhole-mounted Volume/Tone control with battery

(with cable)

DUAL MONO PREAMP FEATURES

Amulet M™

The Amulet M utilizes our newly-designed Acoustic Engine™
technology, providing each transducer with its own extremely low noise
preamp, and providing the ability to easily balance between the two
transducers to get the exact response desired from your instrument.
These signals are combined to a monaural signal, and buffered to
produce a hum and noise-free signal at the endpin jack that’s ready to
plug into any system. This allows you to get the maximum dynamic
range and lowest noise possible from the transducers to produce a clear,
defined sound that easily captures the nuances and dynamics of your
performance.

BUILT-IN LOW CUT FILTER

The Amulet M system includes our high quality low cut filter built into its
circuitry. This filter eliminates any subsonic information below 40 Hz that
might cause noise or distortion in your amplification rig. This filter has
been carefully engineered to leave the low end response of your guitar
intact, even when tuned to far below normal pitch.

ENDPIN JACK

The endpin jack serves as the audio output of the system, the power
on/off switch, and also as the strap button where you can secure the
back of the strap for your instrument. A high-quality Switchcraft jack is
used to insure a long and trouble-free performance. The endpin jack
connects your instrument via a standard ¼” MONO guitar cable to your
amplifier, external effects device or mixer. It also serves as the on/off
switch for the system, so be sure to unplug the cable when not in use to
preserve battery life.

NOTE: Use of a STEREO ¼” cable (sometimes called a TRS
connector) will not allow the system to properly power up, and
must be avoided.

TRANSDUCER INPUTS:
INPUT A

This input typically has the Bass side Acoustic Lens™ transducer
plugged into it in most installations. Its gain is variable, and can be set
using the TRIM potentiometer, located between the Input A and Input B
jacks.

INPUT B

This input typically has the Treble side Acoustic Lens transducer plugged
into it in most applications. Its gain is fixed, and is not affected by the
TRIM control.

Note: The frequency response of the INPUT A and INPUT B
preamplifiers is identical, and the Bass and Treble side Acoustic
Lenses can be plugged into either one with no change in
performance, if so desired. Both input jacks have a shorting
design and will not produce hum or buzz if nothing is plugged in.
