EFFECTS LOOP – The Shenandoah™ Acoustic Pro LT is equipped with an effects loop insert point into the main

amplifier signal path. This loop is useful for inserting compressors and dedicated digital effects processors. The

signal is line level and unbalanced.

EFFECTS JACK – A ¼” TRS effects cancel jack is provided on the back panel to mute the internal effects via

footswitch. Any standard 2-button latching footswitch may be used. The effects signal is muted when the switch

is closed, shorting tip (or ring) to sleeve.

DIRECT OUTPUTS – The Shenandoah™ Acoustic Pro LT contains the most comprehensive direct output section

available on any acoustic instrument amplifier. The XLR balanced and ¼” unbalanced outputs make “real world

sense” when connecting with other equipment. The ¼” unbalanced outputs are true professional line level (+4

dbv) with an output impedance of 1k ohm, and can drive virtually any line level input, including power amplifiers.

The XLR balanced output is “hot” Mic level, rated at –30 dBv. This configuration allows the Shenandoah™ Acous-

tic Pro LT to drive very long cable lengths (250+ feet) without problems or added noise and is compatible with all

commonly encountered mixing consoles. The XLR balanced direct outputs can be “ground lifted” with the global

ground lift switch. This switch lifts pin 1 on all of the XLR balanced outputs to break any ground loops between

the Shenandoah™ Acoustic Pro LT and a PA system (or recording) console. Direct outputs are provided for each

channel, pre eq, pre effects, post channel volume (to take advantage of the dual summing inputs on each chan-

nel), and for the mixed output, post channel eq, post effects, and pre master volume (to aid in sending a “finished”

mixed signal to a PA system, power amplifier or powered speaker).

POWER AMPLIFIER – The Shenandoah™ Acoustic Pro LT uses a state of the art, class D power amplifier

design and a high frequency switch-mode power supply to achieve unprecedented high performance and light-

weight packaging. The switch-mode power supply utilizes high frequency switching to reduce the size and weight

of the magnetic and filter components while increasing the performance by recharging the power supply rails

about 120,000 times each second! The class D amplifier uses digital PWM (pulse width modulation) techniques

similar to those in more familiar digital to analog converters to reduce the size and weight by a factor of 10 times

that of a comparably rated conventional class AB amplifier. Additionally, we developed our own, proprietary limit-

ing and signal processing techniques to give a distinctly analog feel and sound to the class D platform.

POWER INPUT – The Shenandoah™ Acoustic Pro LT utilizes an auto-selecting, self-configuring universal power

supply that operates from 100V to 240 volts, 50 to 60 Hz for worldwide use. Simply utilize the proper IEC cord-set

appropriate for the country the product is being used in. There is an AC mains (line) fuse located in a slide-out

tray at the bottom of the IEC power inlet socket. This is a Slo-Blo 3.5A fuse for all input voltages.

TWEETER LEVEL CONTROL – A Tweeter Level Control is provided for maximum tone flexibility. The “rocker-

switch” control offers FULL tweeter output, - 6db level or tweeter OFF position. Experiment with the different set-

tings to find the best position for your personal taste.

SPEAKER CABINET CONFIGURATION – This high-powered professional product is constructed from birch

and sustainable plywood’s, resulting in an extremely lightweight enclosure with excellent projection and tone.

A bottom-mounted, tilt-back stand is provided so that the speaker can be tilted up towards the performer. The

loudspeaker is our custom designed GBE 12300 cast-frame 12” neodymium magnet structure with a precision

edge-wound voice coil and Kapton bobbin, which is extremely efficient and lightweight compared to conventional

speaker motor structures. A compression tweeter is utilized for the high frequency reproduction and delivers ar-

ticulate, pristine, clarity and texture.
