For the transport and protective packaging, environmentally friendly materials
have been chosen that can be supplied to normal recycling. Ensure that plastic
bags, packaging, etc. are properly disposed of. Do not just dispose of these ma-
terials with your normal household waste, but make sure that they are collected for recy-
cling. Please follow the notes and markings on the packaging.
This product is subject to the European Waste Electrical and Electronic Equip-
ment Directive (WEEE) in its currently valid version. Do not dispose of your old
device with your normal household waste. Dispose of this product through an
approved waste disposal firm or through your local waste facility. Comply with
the rules and regulations that apply in your country. If in doubt, consult your local waste
disposal facility.
Using the product
1. To power the device, connect the mains socket of the device to a properly wired
mains socket which provides the voltage specified in the technical specifications
via the supplied mains cable.
2. Connect the line level output of the guitar preamp or effects unit to be used to
the INPUT jack with a 1/4" jack cable.
3. Connect a guitar speaker cabinet that corresponds to the impedance and load
capacity specified in the technical specifications to the OUTPUT jack using a 1/4"
speaker cable.
4. Set the power switch to the ON position to turn on the power. The PWR / PRO LED
will light up green.
5. Play the instrument. The SIGNAL LED indicates a present signal. If the PEAK LED
is lit, the input signal is too high and there is an unpleasant distortion due to
overload. In this case, reduce the output signal of the device connected to the
input to such an extent that the PEAK LED no longer lights up.
6. To adjust the volume, turn the VOLUME control to the desired position.
7. Use the BASS control to adjust the desired low frequency portion of the overall
signal. The MID knob controls the mids and the TREBLE knob controls the high
frequencies.
8. A built-in protection circuit works to protect the device and components
connected to it. When it triggers, the PWR / PRO LED turns red and the output
turns off. In this case, switch off the device via the on / off switch and switch it
on again a minute later. If the PWR / PRO LED still lights red, please contact our
service.
9. After use, turn the power switch to the OFF position to turn off the power. If
the unit will not be used for a long time, unplug the power cord from the wall
outlet.
Possible hearing damage
Making music for a prolonged period and at high volume can
