• 1‒4: RCA jacks for audio units with live level (e.g. CD player, tuner); the
signal of input 1/PA can be switched to all PA zones via the PA trigger
connector (12)
• 5: 3.5 mm jack input (stereo) for audio units with live level (e.g. MP3
player)
• 6: 3.5 mm jack input (stereo) for audio units with live level or optical
Toslink input for digital audio signals
Input and output for linking up to three MCS-1250 amplifiers for operation
with 18 PA zones; one amplifier can be used as master unit with six signal
inputs and the others as slave units without further signal inputs
Enables two-way communication with a home automation system
Adjusts the input voltage to 115 V or 230 V
3.5 mm jacks (mono) with 12 V control voltage to switch external amplifiers
via a relay
3.5 mm jacks (mono) for connecting IR emitters (accessory) in order to
extend the IR signals from the remote controls of the signal sources. The
IR emitters give you the opportunity to control the signal sources even
when they are placed out of sight or in other rooms. Use the SOURCE 1‒6
jacks to individually control each signal source with an IR emitter or the
ALL jack to control all signal sources with a single IR emitter.
a) Place the extension cable in such a way that the IR emitter is close to
the IR sensor of the signal source (max. 20 distance).
b) The IR sensor on the wall controller receives the signal from the remote
control. From there it is transferred and passed on the IR emitter through
the amplifier. Then the signal is passed on by the IR emitter to the signal
source.
3.5 mm jack (mono) to be able to switch the signal of input 1/PA to all PA
zones via a relay
3.5 mm jacks (mono) for relay operation with parallel systems such as
telephone or home automation systems. Via the MUTE IN jack, the
amplifier can be muted and via the CONTROL OUT jack other devices can
be switched.
• YES (automatic gain control): The volume level of the input sources is
constantly adjusted to 540 mV so that they are played equally loud
• NO: no volume adjustment
• MASTER: when linking several amplifiers, the unit serves as master unit
with connection possibilities for six input sources
• SLAVE 1,2: when linking several amplifiers, the unit serves as slave unit;
is uses the output signal of the main unit
RJ-45 port for connecting the hub for the wall controllers (keypads) via a
network cable (max. 200 m)
Used to plug in the supplied power cable
Only use fuses of the same rating and power. The correct fuse value is
specified on the rear panel. Only replace the fuse when the unit is
disconnected from the mains.
