PLEASE READ IMPORTANT INSTRUCTIONS
BEFORE USING THE AMPLIFIERS! SAFETY
INSTRUCTIONS
To reduce the risk of electric shock the user should not
remove the cover. All operating and safety instructions
should be fillowed. The unit should be kept clear of water,
fluids and moisture and not be operated in damp
conditions. The unit should be operated in a well ventilated
environment. The unit should be kept away from excessive
heat sources such as radiators and if racked with other
power amplifiers there should be a free air flow to vent out
the heat produced check with (dealer). The unit must only
be connected to a power supply as shown on the rear of
the unit with the IEC cable (or similar) provided with
precaution taken to make sure that the grounding (earthing)
or prolarisation is in place and not in defeat mode (ie.
earth disconnected). The power cord must be situated or
routed so as not to be walked upon or pinched or objects
placed upon it with special attention to the area where the
power cable enters the unit. the power cable should be
disconnected during prolonged non usage. The user
should not attempt to service the unit or do anything to the
unit except those things described in this manual. For
service and repair your dealer should be contacted. This
unit complies with the relevant safety regulations.
POWER NOTICE FOR SAFETY
All british and european countries have a nominal 230v
mains power supply which in practice is between 220V
and 240V. In the USA the main power supply is
nominally 115V and in Japan 100V. This unit is factory
set to the correct voltage and this can be checked by
looking at the label on the rear panel near the power
cable. If the unit is to be used in a country other than that
it was shipped to consult your dealer. The unit is suitable
for use with mains frequencies of 50-60Hz. As there are
no user serviceable components inside the amplifier, and
high voltages are present, DO NOT remove the covers!
Be sure to make all audio connections to the amplifier
before connecting to the mains supply. Do not disconnect
the amplifier from the grounded equipment with the
mains connector still plugged into the mains supply.
Important warning! This Unit Must Be Grounded, Do not
Disconnect the Ground Connection! Any sound system
should be connected to ground at one point only. If there
is more than one connection to earth, a GROUND LOOP
can be formed, which allows mains hum to enter the
circuitry, sometimes at a high level. If hum occurs in the
system consult your dealer.

DESCRIPTION
The MP series consists of two models, the Mp1200,
Mp1800. These power amplifiers are designed for
standard 19" (482mm) rack mounting. They have power
supplies with substantial heavy high current transformers
threrefore each model requires rear rack support to prevent
stress on the front panel. These amplifiers are housed in
steel casing suitable for racking in professional flight cases.
OPERATING
Before switching on the power amplifier ensure that ALL
audio inputs are connected, ALL speaker cables are
securely connected, ALL volume controls on the front panel
are fully off and that the mains connections are safely and
fully off and that the mains connections are safely and
securely connected at the supply and amplifier unit.
CLASS 2 WIRING
Class 2 wiring for all terminals provided the audio output
power exceeds 10W per channel under normal operating
conditions or the apparatus is intended to be installed or
interconnected in the field by a skilled person.
