4. Operation Summary
•
Cabling and startup
Check if your local mains voltage (e.g. 120 V in the USA, 230 V in Euro-
pe) complies with the required operating voltage for your amplifier.
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 off (not pressed).
Then make all the necessary cable connections
(mains, instrument etc.).
Now you may turn on your amplifier with the
power on
switch loca-
ted 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 ad-
apt the amplifier 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 flashes
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 flash. In case you find the level setting
difficult 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 sufficient input si-
gnal 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
The three-band equalizer with individual
bass
,
middle
and
treble
control of your
Compact
60
2
has been designed in such a way that it
both complies with the special requirements of acoustic instruments
and also with the more general demands of other sources. The
colour
switch activates a midrange contour filter which is especially useful
for picking techniques.
One more note: Adjusting the EQ controls can also affect the level
setting. Whenever you see the
clip
indicator flashing frequently, you
should slighty correct your
gain
setting (see ‚Level adjustment‘).
• Effects
The
Compact
60
2
has a built-in (internal) digital effect processor. The
return
control determines the intensity of the internal effects (left
stop = no effect). Furthermore an additional effects unit (external ef-
fect) may be connected. For this purpose please use the send and
return sockets located on the back of the amplifier (
send
goes to In-
put,
return
is connected to the output of the external effects device).
The intensity is then adjusted at the external effects unit. The external
effects loop works in ‚parallel‘ mode, i.e. the effect 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 effects on and off.
We wish you hours of happy playing with your Compact
60
2
