1. Introduction

Welcome to AER!

Thank you for choosing the Compact 60
sional, powerful and compact amplier system for acoustic instru­ments in superb quality with AER‘s typical authentic, transparent and
self-asserting sound performance. Two channels make it possible
to operate a microphone and an instrument independently of each
other. The dynamically controlled power amplier and the broad­sprectrum loudspeaker system guarantee distortion-free repro­duction even at high volumes.

We wish you hours of happy playing with your Compact 60

The following guidelines shall help minimize the risk of injury through
re or electric shock.

1. Carefully read these safety notes before you use the device!

2. Keep these safety notes in a safe place.

3. Pay attention to all warnings, instructions and additional texts on
the unit.

4. Do not install or use your amp in close proximity to water or if you
are wet yourself.

5. Use your amp in a safe place where nobody can step on cables or
trip over and damage them.

6. Pay attention to an unhindered air circulation around the amp, ne­ver obstruct the air vents or grilles.

7. Always pull the mains plug before cleaning your amp. Use only a
dry cloth for cleaning. Avoid the use of detergents and do not let
any liquids seep into the unit.

3. Controls and Connections

8. Use only the right fuses with the same current rating and trigger
characteristic as replacements. Never mend fuses! Pull the mains
plug before replacing a fuse. Should a fuse blow again after a
short while, the device needs to be checked.

9. Never install your amp close to devices with strong elec­tromagnetic elds such as large mains transformers, revolving
machines, neon illumination etc. Do not lay signal cables parallel
to power current cables.

10. There are no user-servicable components inside the unit. To avo­id the risk of an electric shock, the unit must not be opened. All
maintenance, adjustment and repair works should be carried out
by qualied sta only. Any unauthorized tampering will void the
2-year warranty.

11. In keeping with the EMV regulations screened cables with cor­rectly tted connectors must be used for all signal connections.

12. Always use an earthed power supply with the correct mains volta­ge. If you are in doubt about the power outlet‘s ground, have it
checked by a qualied technician.

13. Cable up your amp only when it is powered o.

4. Operation Summary

• Cabling and startup

Check if your local mains voltage (e.g. 120 V in the USA, 230 V in Euro­pe) complies with the required operating voltage for your amplier.
The proper mains voltage is printed on the rating plate on the rear
panel of the unit, e.g. AC 230V (AC means alternating current).

Please take care that the master, return and all gain controls are
set to zero (left stop) and all other controls to their center positions.
The pushbuttons should be switched o (not pressed).

Then make all the necessary cable connections
(mains, instrument etc.).

Now you may turn on your amplier with the power on switch loca­ted on the rear. The green power control LED will indicate operational
readiness.

• Level adjustment

Using the gain controls, high/low and line/mic switches you can ad­apt the amplier to your signal sources (guitar pickups, microphone
etc.) to achieve the best possible signal-to-noise ratio (SNR).

First adjust the line/mic switch according to your signal source: mic is
suitable for microphones, line for pickups and other signal sources.

Turn the gain control clockwise until the red clip indicator ashes
momentarily when playing with a strong attack. Now lower the gain
control (and also the instrument‘s volume control) again slightly to
get some headroom for an undistorted reproduction. The clip control
LED should now only rarely ash. In case you nd the level setting
dicult because the input signal is too strong, press the high/low
switch as well. If the input signal is too weak, the gain control must be
increased accordingly. With signal sources with a sucient input si­gnal strength the gain control should be adjusted between the ‘ 9:00
and 11:00 o‘clock‘ position. Finally set the desired overall volume level
with the master control.

• Equalization

control of your Compact 60
both complies with the special requirements of acoustic instruments

has been designed in such a way that it

and also with the more general demands of other sources. The colour
switch activates a midrange contour lter which is especially useful
for picking techniques.

One more note: Adjusting the EQ controls can also aect the level
setting. Whenever you see the clip indicator ashing frequently, you
should slighty correct your gain setting (see ‚Level adjustment‘).

• Eects

2

The Compact 60
return control determines the intensity of the internal eects (left

has a built-in (internal) digital eect processor. The

stop = no eect). Furthermore an additional eects unit (external ef­fect) may be connected. For this purpose please use the send and
return sockets located on the back of the amplier (send goes to In­put, return is connected to the output of the external eects device).
The intensity is then adjusted at the external eects unit. The external
eects loop works in ‚parallel‘ mode, i.e. the eect signal is blended
with the original signal.

A standard double footswitch can be connected to the footswitch
socket on the rear of the amp with a stereo cable. This switch can be
used to turn the internal and external eects on and o.

We wish you hours of happy playing with your Compact 60
