1.- M
ONITOR (1 W, 8 Ω)
: output for connection of a low impedance loudspeaker 8 Ω to monitor the output.
2.-
PRIORITY
: when closing the contacts of these two terminals, the order of priority of the inputs changes.
The order of priority without closing the contacts is as follows:
TEL.PAGING > MIC 1 >
M-46
Microphone > MIC 2, MIC 3, LINE 4, LINE 5, MP3 Module.
The order of priority when closing the contacts is as follows:
MIC 1 > TEL.PAGING >
M-46
Microphone > MIC 2, MIC 3, LINE 4, LINE 5, MP3 Module.
3.-
TEL. PAGING
: telephone input connection terminals. These allow you to connect to a telephone
switchboard to prioritize paging over other inputs. Make the connection between terminals T and G.
Consult the characteristics of the control unit to adjust to the input level of the amplifier.
4.-
FM ANT
: FM antenna input.
5.-
REC OUT
: balanced or unbalanced line output. Signal output for recording, mixer, power stage, etc.,
screw terminal connections. general speaker output. For connection of low impedance 4 Ω and high
impedance 100 or 70 V lines, connect the speaker line between the COM terminal and the desired
impedance or V line.
6.-
OUTPUT
: loudspeaker general output. For the connection of low impedance loudspeakers 4 Ω and in
high impedance lines of 100 or 70 V, connect the loudspeaker line between the COM terminal and the
impedance or line in V required.
7.-
GND LIFT
: this switch is normally in the GND position. If there are grounding noises, switch to the LIFT
position, disconnecting the device from the ground.
8.- AC power socket.
9.-
ZONE
: microswitches to select in which zone or zones the TEL PAGING input will be heard.
10.-
VOLUME
: a rotating dial that regulates the volume of the TEL PAGING input.
11.-
CH 4, CH 5
: line level inputs. Allow for the connection of audio sources, 2 x RCA connectors.
