Safety instructions
The wires of the main power line have the following
colours:
GREEN and YELLOW: (E)
BLUE: (N)
BROWN : (L)
!
!
!
!
!
DO NOT run microphone cables near mains,
data, telephone or 100V line cables.
DO NOT run 100V line cables near data,
telephone or other low voltage cables.
DO NOT exceed 90% of the amplifiers output
power when using 100V line (speech only).
DO NOT exceed 70% of the amplifiers output
power when using 100V line (high level
background music).
DO NOT use re-entrant horn loudspeakers for
background music unless the loudspeaker has
been specifically designed for this purpose.
!
!
!
!
!
AVOID jointing the microphone cable, when
this is unavoidable make sure a good screened
connector is used, e.g. XLR.
ALWAYS use a balanced or floating low
impedance microphone terminating into a
balanced input on long microphone cable runs.
ALWAYS use a mains grade double insulated
cable for the loudspeaker cable runs.
ENSURE that all loudspeakers are in-phase.
ENSURE that there are no short circuits on the
loudspeaker line before connecting to the
amplifier.
As the colours of the wires in the mains lead of this
apparatus may not correspond with the coloured
markings identifying the terminals in your plug
proceed as follows:
The wire which is coloured green and yellow must
be connected to the terminal which is marked by
the letter E or by the safety earth symbol or
coloured green and yellow. The wire which is
coloured blue must be connected to the terminal
which is marked with the letter N or coloured
black. The wire which is coloured brown must be
connected to the terminal which is marked with the
letter L or coloured red.
If a 13 Amp (B.S.1363) plug or any other type of
plug is used,a 5 Amp fuse must be fitted either in
the plug or at the distribution board.

Put the Mixer Amplifier in a position with enough
space enough fresh air to minimise the heat in the
system.
Do not place the Mixer Amplifier close to of heat
sources or a heater.
Do not expose the Mixer Amplifier sunlight or
heavy dust.
If you use the Mixer Amplifier as a tabletop unit
please make sure that the 4 feet are mounted on
the bottom side.

EJECT
The housing of the Mixer-Amplifier is a 19 inch
rack standard construction. Please check if you
have enough space for cooling the amplifier. For
the optimum mounting in the 19” rack you should
fix the mixer - amplifier in the rack-frame with 4
screws.

Positioning Mixer Amplifier
The mixer amplifer pulls fresh air through the small
holes in the bottom sheet and pushes the exhaust
air through the long holes in the top sheet. Please
make sure that the internal space of the rack
system is cooling and you have a room maximum
temperature of 40°C..
We recommend to install a cooling system at the
rear site of the racksystem to support the transport
the exhaust air in the racksystem.

The LED-Display shows the recording level of the
Mixer-Amplifier. The green LEDs show the range in
which the MX-AMP could be operated
permanently. The red LED shines only when
running in full conduction. This zone is not
advisable for long-term usage.
LED - Display
With this switch you turn on the apparat.
Position I = apparat is on
Position 0 = apparat is off
After turning the machine on, the LED is shining
blue. Before turning the machine on, the Master
controller should be set to a low volume.

The amplifier provides two different Loudspeaker
zones.
The - Output gives an output
with 70V and 100V. In Europe use normal 100V
and in USA 70V.

100V Speaker Output 8ohm Speaker Output
This output allows connection of standard low
impedance loudspeakers. The minimum load
impedance must be 8ohm When two or more
loudspeakers are connected, ensure that they are
wired in such a way, that the load impedance is
between 8ohm and 16ohm.
