ELECTRICAL CONNECTIONS AND SUPPLY
WARNING: This appliance must be earthed. Please check that the supply voltage
details given on the rating label (located on the rear panel) are in accordance with
your electricity supply.
FITTED PLUG. This appliance is fitted with a moulded-on plug. If the socket outlets
in the home are not suitable for the plug supplied with this appliance (or the plug
becomes damaged and requires replacement), it should be cut off and an appropriate
three-pin plug fitted as detailed later this section.
IMPORTANT: A moulded plug severed from the mains lead must be destroyed
immediately. Such a plug with a bared flexible cord is hazardous if engaged in a live
socket outlet.
If the fuse of the moulded-on plug is to be replaced, remove the coloured fuse cover
on the underside of the plug, and use a suitably certified 3A fuse approved by ASTA
to BS1362, i.e., the fuse carries the ASTA mark. The fuse cover must always be
replaced. Never use the plug with the fuse cover omitted. Replacement fuse covers
are available from your local Authorised Service Agent.
INSTRUCTIONS FOR USE. Plug the mains lead into a suitable power socket and
connect your instrument to the input socket of the amplifier with a suitable guitar
lead (this lead is not supplied with the amplifier, but is normally supplied with the
electric guitar). Finally, press the Power Switch to the ON position, the power LED
will glow and your amplifier is ready for use.
WARNING: If, after you have followed the instructions outlined above, your
Amplifier fails to function, please contact your local distributor. Under no
circumstances remove the rear panel of the Amplifier whilst it is connected to
the mains supply.
Electrical appliances must never be used where there is a danger of water splashing
onto the unit.
Your attention is drawn to the instructions printed on the notice attached to the back
of the Amplifier.
Exposure to extremely high noise levels may cause a permanent hearing loss.
Individuals vary considerably to noise induced hearing loss but nearly everyone will
lose some hearing if exposed to sufficiently intense noise for a prolonged time.
CAUTION: CHASSIS SURFACE HOT.
WARNING: TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT EXPOSE THIS EQUIPMENT
TO RAIN OR MOISTURE.
AVIS: RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR.
ATTENTION: SUPERFICIE DE CHASSIS CHAUDE.

INPUT SECTION FEATURES:
MASTER SECTION:
(1) 1/4 Line/High Impedance Input: This may be used as either a high impedance microphone input
or a line level device such as: tape players, CD player, effects returns or radios. It will also allow
connection from an electric guitar, bass, or keyboard. It is a 2-conductor input with an impedance of
10K ohms. Both the high and low impedance inputs may be used simultaneously.
(6) Master Volume: This controls the overall volume level of the entire amplifier. Typical operation is
between 4 and 8.
(7) Master Reverb: This controls the level of internal reverberation added back to the mix.
(8) Tape Volume: This controls the level of the playback inputs (RCA jacks on rear panel).
(9) Master Low: This controls the overall amount of bass frequencies (100 Hz). This control allows
+/- 15dB of boost or cut.
(10) Master Middle: This controls the overall amount of middle frequencies (1K Hz). This control
allows +/- 15dB of boost or cut.
(11) Master High: This controls the overall amount of high frequencies (10K Hz). This control allows
+/- 15dB of boost or cut.
(12) Main Output: A 1/4 2 conductor line output. The impedance is 1K ohm. @ -10dbv. It is used to
allow the combined signals of the entire mix to be sent out to additional amplifier (for more overall
power or to create a mirror image for a monitor amp), or for patching in external equalizers or effects
such as delays or digital processors.
(2) 3 Pin Low Impedance Microphone Input: This input is for balanced low impedance microphones.
Phantom power (15 volts) for condenser microphones is always on and available. It has an input
impedance of 1K ohm. The connector is wired as: Pin 1 = shied; Pin 2 = positive (hot); Pin 3 = negative
(cold).
(3) Volume Control: This is the volume control for each channel. It sends the signal to the master mix
buss. Typical operation is between 4 and 8, dependent upon the device(s) on that channel, Please
remember that it acts like a pre-amp, so if you are using a device that has a volume output control (i.e.: a
tape or CD player) you will need to do some level matching by adjusting the level controls on each unit.
(5) Reverb Control: This is a send control to the reverb buss. It controls the amount of reverberation
added to the input signals.
(4) Tone Control: This is the adjust the overall tone of the individual inputs. It is set at 5Khz. Since it
is a cut or boost control, (+/- 15dB) it will add or diminish presence frequencies in the sound.

BACK PANEL:
(1) Power: This switches the unit on or off. When the unit is powered up, a red LED will come on also.
(14) Aux Input: A 1/4 2 conductor line level output. output from the effects buss. This jack is used
primarily to connect to and external effects device such as a chorus, delay, or echo.
(13) Reverb Output: A 1/4 2 conductor line output. It is used to allow the processed signals controlled
by Reverb volume to be sent out to additional amplifier (for more overall power or to create a mirror
image for a monitor amp.)
(15) Reverb Footswitch: A 1/4 2 conductor foot switch jack. It is used to plug in a push on push offtype
footswitch to turn the internal reverb buss on or off.
(3) External Output: These are 2 conductor 1/4 speaker outputs. You may connect 1-8
ohm speaker cabinets. Do not go below rated minimum impedance.
(4) Tape Play (L/R): These RAC jacks are for brining in a tape deck, CD player or other line level
source. The impedance is 10K ohms @ -10 dBv.
(5) Tape Record (L/R): These RC jacks are for hooking up a tape deck to record from the mixer. Both
channels are summed into mono for compatibility. The signals are taken pre-master section, meaning
that they are without reverb or the master tone section, and does not include the Tape In signal. The
impedance is 1K ohms @ -10 dBv.
