Operating elements
Using the product
- 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.
- Connect the line level output (0.775 V) of the guitar preamp or effects unit to be used to the INPUT jack with a 1/4″ jack cable. Connecting an electric guitar directly to the input leads only to a significantly weaker output power signal.
- 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.
- Set the power switch to the ON position to turn on the power. The PWR / PRO LED will light up green.
- 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.
- To adjust the volume, turn the VOLUME control to the desired position.
- 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.
Possible hearing damage
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 is not going to be used for a longer time, unplug the power cord from the wall outlet.
