AC POWER switch
Turns the AC power unit on and off, which suppresses any interference
noise in emergency power operation.
20
CH1-4 / COM terminals
Terminals for zones 1 to 4 for connecting 70 V / 100 V speakers and
common ground connection. Always use the protective cover during
operation to avoid short-circuits.
21
Antenna connection
Connection for the included cable areal or your analog cable connection.
When using the cable areal, uncoil its entire length and place it e.g. along
the wall.
22
Power input with fuse holder
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.
23
SPEAKER OUTPUT terminals
• 70V/100V: for connecting 70 V and 100 V speakers
• 4Ω/8Ω/16Ω: for connecting 4-16 Ω speakers
• COM: common ground connection for all speakers
Always use the protective cover during operation to avoid short-circuits.
24
DC24V IN terminals
Screw terminals for a 24 V emergency power. Always use the protective
cover during operation to avoid short-circuits.
25
LINE output
RCA jacks for the mixed signal to connect, e.g. an additional amplifier.
26
LINE 4 input
RCA jacks for connecting audio units with line level (e.g. CD player).
27
LINE 3 input
RCA jacks for connecting audio units with line level (e.g. CD player)
28
MIC 3/LINE 2 input
Unbalanced 6.3 mm jack for connecting a dynamic microphone or a line
level audio device.
29
MIC 2/LINE 1 input
Unbalanced 6.3 mm jack for connecting a dynamic microphone or a line
level audio device.

CONTROL DIP switches
• 1 and 2: line level (upper position) or microphone level (lower position) at
inputs MIC 3/LINE 2 or MIC 2/LINE 1
• 3: phantom power on (upper position) or off (lower position) at input MIC 1
• 4: priority circuit on (upper position) or off (lower position) at input MIC 1
31
MIC 1 input
Balanced XLR jack for connecting a microphone. For a phantom-powered
microphone set DIP switch 3 to the upper position. To enable the priority
circuit for this input, set DIP switch 4 to the upper position. Then the level of
the other inputs is attenuated when an announcement is made via this input.
