DANGER!
Electric shock caused by high voltages inside
Within the device there are areas where high voltages may be present. Never
remove any covers.
There are no user-serviceable parts inside.
DANGER!
Electric shock caused by short-circuit
Always use proper ready-made insulated mains cabling (power cord) with a pro‐
tective contact plug. Do not modify the mains cable or the plug. Failure to do so
could result in electric shock/death or fire. If in doubt, seek advice from a regis‐
tered electrician.

CAUTION!
Possible hearing damage
The device can produce volume levels that may cause temporary or permanent
hearing impairment. Over an extended period of time, even levels that seem to
be uncritical can cause hearing damage.
Decrease the volume level immediately if you experience ringing in your ears or
hearing impairment. If this is not possible, keep a greater distance or use suffi‐
cient ear protectors.
CAUTION!
Risk of injury due to heavy weight
Due to the heavy weight of the device, at least two persons are required for trans‐
port and installation.

NOTICE!
Power supply
Before connecting the device, ensure that the input voltage (AC outlet) matches
the voltage rating of the device and that the AC outlet is protected by a residual
current circuit breaker. Failure to do so could result in damage to the device and
possibly injure the user.
Unplug the device before electrical storms occur and when it is unused for long
periods of time to reduce the risk of electric shock or fire.

4 Installation and starting up
Unpack and carefully check that there is no transportation damage before using the unit. Keep
the equipment packaging. To fully protect the device against vibration, dust and moisture
during transportation or storage use the original packaging or your own packaging material
suitable for transport or storage, respectively.
Establish all connections as long as the unit is switched off. Use the shortest possible high-
quality cables for all connections.
CAUTION!
Risk of injury due to heavy weight
Due to the heavy weight of the device, at least two persons are required for trans‐
port and installation.

1[INPUT]
1/4" phone socket to connect your instrument.
You can also connect other active signal sources like CD or MP3 players, keyboards, mixers etc. to this input.
2[GAIN]
Control to adjust the preamp gain of the signal (volume) in channel 1.
3[VOICE]
Control to adjust the tone colour of the signal in channel 1.
4[CHANNEL SELECT]
Channel 1 / 2 select switch. The LED of the active channel lights permanently during operation.
5[GAIN]
Control to adjust the preamp gain of the signal (volume) in channel 2.
6[VOICE]
Control to adjust the tone colour of the signal in channel 2.

7[COMPRESSOR]
Pushbutton for enabling the built-in compressor.
The LED [ACTIVE] lights permanently during operation, when the compressor is enabled. The LED [ON] indicates that
the compressor circuit is active and processes the signal. The signal level at which the compressor processes the
signal is affected by the gain controls (the higher the gain, the more the signal is compressed).
8[7-BAND EQUALIZER]
Use the sliders of the equalizer to shape the sound of the amplifier depending on the frequency. In the zero position,
the signal is reproduced unchanged.
9[LIMIT OFF]
Pushbutton for enabling or disabling the built-in limiter.
The limiter monitors the signal level of the amplifier and detects the impedance of a connected speaker automati‐
cally. The protection circuit is automatically activated when the unit is turned on and attenuates an excessive output
level to an uncritical level to avoid distortion.
10 [VOLUME]
Overall volume control.
Connections and operating elements

11 [CD / LINE IN]
RCA input for connecting a CD player, cassette deck or the like.
12 [D.I. OUT]
Balanced XLR output for connecting the amplifier to a mixer.
The amplifier signal is supplied unchanged to the connected mixer.
13 [TUNER OUT]
Output for connecting a tuner (6.35 mm phone socket).
14 [FOOTSWITCH]
Connection for an optional footswitch (6.35 mm phone socket).
Use a foot switch to toggle between the channels of the amplifier.
15 [POWER]
Mains switch. Turns the device on and off.
If there is no signal input at the [INPUT] jack for 30 minutes, the device will automatically enter standby mode. As
soon as the [INPUT] jack receives a signal again, the device switches back to normal mode.
