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.

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. 

The new Mp range of power amplifiers from Wharfedale is 
designed to give musicians, club owners and DJ's the 
performance, reliability and sound quality they require.

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.

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 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.
