O perating I nstructio ns
This is to carry the signal to the P.A. system for larger gigs. It is balanced and low impedance to ensure that
no noise is added to the signal on the way to the mixer.The level of this signal has been set to be similar
to that from a microphone so that it will work without overloading the input on a desk that has no input
Pad switch.
The signal connections are as follows: Pin 1 = Ground, Pin 2 = Signal +, Pin 3 = Signal -.
The DI signal can be switched to be PRE or POST EQ. PRE EQ is before any of the amplifier's facilities or
EQ but after the INPUT GAIN control. POST EQ is after all internal facilities and includes the external
effects loop.
MUTE/TUNE
The front panel MUTE switch provides a mute facility that can be used to silence all outputs from the
amplifier except that from the TUNER output socket.This enables silent tuning to be carried out whilst the
amplifier speaker outputs, the DI the Effects Send and the Line Output are all muted. Once in tune the
amplifier can be un-muted and playing resumed.This switch can also be used as a STANDBY switch for
silencing the amplifier during pauses in its use. A blue LED below this switch will illuminate to indicate
when the amplifier is Muted.
To make use of the Tuning facility plug the output from the TUNER socket into the INSTRUMENT input on
your tuner.
OUTPUT LEVEL
The OUTPUT LEVEL control is used to set the stage volume of the amplifier. Use this control to adjust for
increases or decreases in your playing volume and not the INPUT GAIN control, this should always be left
set to the optimum for your instrument.
LINE OUTPUT
The LINE output is for connection to external power amplifiers and speakers to allow you to build a larger
more powerful system.This output is situated after the OUTPUT LEVEL control to allow the entire
connected system to be turned up and down with a single control.
If you require a line output that is not affected by the OUTPUT LEVEL control you may use the EFFECTS
SEND jack socket, this will obviously not include any effects loop signal.
REAR PANEL FACILITIES
EFFECTS SEND/RETURN
A serial effects loop is provided at a level of 0dB.
The EFFECTS SEND socket can also be used as a
Line Out socket if required as the signal path
through the preamp is only broken when a jack plug
is inserted into the EFFECTS RETURN socket.
The EFFECTS SEND is situated after the EQ.
SPEAKER OUTPUT
The Speaker Output sockets are also situated on the rear panel of the unit and are provided on both Jack
& Speakon connectors.
