6 D.I. OUT: This socket provides a balanced output for direct injection of the amplifier signal into a mixing desk or
additional power amplifier.
7
GROUND LINK: If a hum loop is experienced when other equipment is connected to the D.I. OUT socket, use this
switch to reduce or remove it completely.
8
EFFECTS LOOP: SEND/LINE OUT: Connect the input of your external effect to this socket. All of the signal
leaves the amplifier via the `Send' socket to be processed and comes back from the effects via the `Return` socket.
Some Effects are better suited to being between the guitar and amplifer input - these are foot pedal types / distortion /
wah wah pedals etc. Rack mount effects will work better in the FX loop on the amplifer rear. Stomp boxes are
normally designed for small signals such as a guitar output whereas rack mount FX are designed for the higher signal
level obtained from an FX send. This socket can also be used as a Line Level Out.
9
BY-PASS/LEVEL SWITCH: This switch allows the effects loop to be by-passed if not in use, it also gives you the
option of running the FX loop at 0dB (750mV) or at -10dB (250mV) to suit your processor.
10
EFFECTS LOOP: RETURN: Connect the output from your external effects to this socket. The effects loop allows
you to connect external effects such as tremolo's and delays to your amplifier. All of the signal leaves the amplifier via
the `Send' socket and comes back from the effects via the `Return` socket. Use the output level control on your FX to
control how loud the FX return signal sounds. This is an insert type control, therefore you need to set the Dry/ Wet
mix in your FX processor.
11
FOOTSWITCH SOCKET: Provided for the connection of a Laney FS2 footswitch (optional) .This allows you to
remotely switch the chorus and reverb On/Off.
