Acoustic Guitar Amplifiers

Model: Alpha (40W)

A single channel, 40 Watt acoustic guitar amp - stunning AER sound quality at the lowest possible price. Small and lightweight in design, the Alpha is easily powerful enough for standalone use in smaller venues, and the DI and line outputs enable connection to a P.A. system for larger stages.

Separate outputs are provided for headphones and a tuner, and a built in digital reverb / delay unit with 4 preset sounds complements the standard 3-band eq, adding more flexibility to the sound.

Includes soft cover.

Inputs	Channel 1: combined XLR / 1/4" jack socket, mic / line level with 24V phantom power Channel 2: 1/4" jack socket, piezo / line level
Outputs	DI-out, line-out, headphones-out, tuner-out, effects loop
Controls	Channel 1: mic / line input selector, gain Channel 2: piezo / line input selector, gain, 'colour' Overall: 3 band eq, effects return*, master volume

Model: Compact 60 (60W)

A 60 Watt, 2 channel amp for guitar and voice. Tiny (13" x 10" x 9") and lightweight (only 9kg), but don't be fooled - this amp has plenty of power, and the sound quality, like all other AER products, is superb.

The compact 60 is ideal for use in the home and small / medium size venues as a standalone unit; alternatively the DI and line outputs enable it to be connected up to a larger P.A. system, without the potential feedback problems and general inconvenience associated with using microphones.

Explanation of Technical Terms

Unsure about some of the technical terms used on this page?  We've explained a few of them below, but if there's anything you still don't understand, please contact us and we will be happy to help!

Obscure knobs and switches:

• Colour control - switches on a special pre-set eq that gives piezo-electric (under-saddle) acoustic guitar pickups a more natural sound. Cuts the mid-range and boosts the treble.
• Contour control - adjusts the frequency that's being cut or boosted by the 'bass' control on the eq
• Mid-sweep control - adjusts the frequency that is being cut or boosted by the 'mid' control on the eq
• Notch filter - a narrow-band filter enables a particular frequency to be removed (e.g. if it is causing feedback) without radically altering the overall sound
• Q control - adjusts the width of the frequency band affected by the 'mid' control on the eq, i.e. the number of frequencies either side of the frequency on the 'mid-sweep' control that will be cut or boosted. Higher Q values mean that a narrower frequency range is affected.

Input and output issues:

• Phantom power - because of the way they work, most condenser microphones need an external voltage source to power them (those that don't use batteries). Dynamic microphones (e.g. ordinary vocal mics) don't need this phantom power, although it won't harm them if it's accidentally left on (N.B. some other types of microphone e.g. ribbon mics can be damaged by phantom power, so be careful)
• Line level signals - includes most instruments and other audio equipment eg. active (undersaddle) acoustic guitar pickups, magnetic (soundhole) acoustic guitar pickups, electric guitars, keyboards, effects units, CD and tape players.
• Piezo level signals - instruments with a low output level such as passive acoustic guitar pickups, that need special input settings with extra signal boost
• Effects loop - allows an external effects unit to be used with the amp / P.A. system, the effects signal can be mixed into the overall sound using the 'effect return' control.

Speaker jargon...

• Bi-radial - speakers that point in two different directions, spreading out the sound they produce over a wider area.
• Co-axial - speakers that point in the same direction as each other, projecting sound over a longer distance.
• Crossover - a device that splits the incoming sound, sending bass frequencies to the bass speakers and mid / high frequencies to the mid / high frequency speakers. The frequency at which they are split is known as the crossover frequency.
