2. Audio Inputs
2.1 Mic Inputs / Priority
The input sensitivity of these MIC inputs (35, 37, 39, 41) can be adjusted by the
separate GAIN controls (36, 38, 40, 42) in the range of 5
– 300mV.
Every input has separate HI and LO tone controls (12, 14, 16, 18) at the front, that
allow for tone adjustment if necessary.
The input impedance is 600 ohms.
The PHANTOM switch (30) allows activation of a 48V phantom power in case of
using an electret mic. An activated phantom power is indicated by the red LED next
to the PHANTOM switch (30).
The dip switches (27) allow to activate a VOX controlled priority for the particular MIC
input and results in an automatic muting of the AUX inputs (43, 33, 45, 1).

2.2 Aux Inputs
Connect AUX sources here (43, 44, 45, 1).
The input sensitivity is 775mV at 47kohms.
The inputs can be selected by the AUX selector buttons (7) at the front of the unit.
The input has HI and LO tone controls (20) at the front that allow for tone adjustment
if necessary.
2.3 Connector for Paging Station
At this input (34) you can connect a paging station UPM 8001.
The volume of the announcement can be adjusted with the MIC 1 control (11).
A 2-tone pre chime can be activated by switch (26).
Attention:
The connector always supplies 24V phantom power.
A
simultaneous
use of the PAGING STATION input (34) and the MIC 1 input
(35) is not possible.
PRE CHIME
2.4 Gong, Alarm, Mute All & Priority Out
By shorting MUTE ALL and GND all signals at the speaker output
will be muted.
By shorting the contacts 4T CHIME START and GND the internal 4-tone
chime will be triggered. The chime volume can be adjusted by the
CHIME VOLUME control (28).
By shorting the contacts DIN ALARM START and GND you can trigger the internal
DIN alarm. The alarm is activated as long as these contacts are shorted.
The alarm volume can be adjusted by the DIN ALARM CONTROL (29).
