PRODUCT DESCRIPTION

 –The Shenandoah™ Acoustic Pro LT is a two channel – 4 input, professional 300 

watt acoustic instrument amplifier with two blendable preamps per channel—FET and 12AX7 Tube. The 12AX7 tube 

design adds warmth and character to the amplified acoustic instrument without distortion. 

This new compact, lightweight combo also features two digital effects processors – one for each channel. The pow

-

erful Class D amplifier is combined with an advanced 300 watt 12” Neodymium loudspeaker, providing full-bodied, 

efficient, articulate acoustic output.

Each channel of the preamp is equipped with both a ¼” unbalanced line input and an XLR balanced microphone input 

(with Phantom power). The two inputs on each channel are summed (mixed) together at a 1:1 ratio. Each channel 

then passes through independent 3 band equalizers with a sweepable midrange frequency band. This powerful equal

ing and feedback control. A Phase Switch is also provided to reduce acoustic feedback and enhance both the feel and 

response.

The advanced design of the FET/TUBE preamp, 300 watt power amp and light-weight cabinet design are further aug

mented by a full-featured rear panel which offers three direct balanced outputs with ground lift switch, 3 unbalanced 

line outputs, effects loop, effects cancel jack, aux. input section and extension speaker jacks.

The Shenandoah™ Acoustic Pro LT has redefined the standard in acoustic amplifiers for years to come.
