REAR PANEL CONTROLS

POWER

– On/off switch for main power. For your safety remember to connect power cord to the amplifier

first,  then  to  the  AC  outlet  and  then  turn  this  switch  on.  It  works  backwards  when  you  want

disconnect  unit  –  firstly  turn  switch  off,  then  disconnect  cord  from  the  AC  outlet  and  finally

disconnect cord from amplifier.

MAINS IN AC

– AC terminal with integrated fuse compartment for connection to the mains power supply. To

exchange the fuse you have to disconnect power cord first and use small screwdriver to remove

fuse carrier. Use only the same size and type for replacement. Using a fuse with a different rating

than specified can cause damage to your amplifier.

TUNER OUT

– Dedicated output for tuners. Signal remains active in this output even when amplifier is muted

which allows for “silent tuning”.

SEND & RETURN

– Insert point for external effects unit. To use effects loop connect the send socket to the input

of the effects unit and the output of the effects unit to the RETURN socket. The effects loop is of

the serial type.

LINE OUT

– Unbalanced output to external devises (auxiliary power amplifier, mixing console etc.).

DI OUT

– Balanced XLR output to external devices such as PA and studio mixing consoles.

PRE-POST

– switch to control the DI OUT. In PRE position the signal at DI OUT is the signal without any

compression  or  equalization. In  POST  position  signal  at  DI  OUT  is  fed  after  the  compressor,

tone controls and effects loop.

GROUND LIFT

– Switch to lift the chassis ground connection from the DI output. Helps to prevent hum caused

by ground loops.

SPEAKER OUT

– Output combo connectors (¼” jack and lockable coaxial) for connecting speakers. These are

connected in parallel. Connect only speaker combinations with a summary load equal or greater

than 4
