EA PANEL
1.- PAGING AMP 100 V INPUT: 100 V signal input coming from an optional paging amplifier. This amplifier
is used to be able to maintain the background music in the zones in which the microphone
announcement is not going to be made. The power of this amplifier must be at least the same as that
of the total load of the connected loudspeakers.
2.- ZONES 100 V OUTPUTS: terminals to connect the zone 1 to 6 loudspeaker lines. In order to
activate/deactivate the zones, use the switches on the front. Only loudspeakers with a 100 V line
transformer must be used with the zone selection terminals. Connect the positive of each zone to the
corresponding terminal Z1 to Z6 and the one common to all the zones to a COM terminal. 120 W
maximum in each one of the zones. The total connected power in loudspeakers must not exceed the
power of the amplifier, 480 W.
3.- ALL ZONES: 4 Ω low impedance loudspeaker output.
4.- NIGHT INGE : paging signal input to be used as a precedent to the TEL PA IN signal. The volume
of this tone can be regulated with the RIN ER knob on the front panel.
5.- PAGING: telephone input terminals. Allow the connection of a telephone switchboard to make
announcements from the switchboard with priority over the rest of the inputs. Consult the switchboard
characteristics in order to adjust the amplifier input level. The signal level can be adjusted with the
PA IN control on the front panel.
6.- MESSAGE FI ST P IO ITY: contact closure that gives maximum priority to the messages stored in
the MZ-648 microphone. When activated, the messages played by the microphone MZ-648 will not be
attenuated even if audio is played from an input with greater priority.
7.- P E OUT AMP IN INSE T: direct signal input to the amplifier. When connecting an audio input in this
input, the amplifier inputs are cancelled out.
8.- PAGING OUTPUT-: paging signal output to the external warning amplifier if you wish to use dual mode.
This amplifier can be used for paging and the internal amplifier to be able to maintain the background
music in the zones in which the announcement is not going to be made. The power of this amplifier
must be at least the same as the total load of the connected loudspeakers.
9.- EC: signal output for recording, mixer, amplifier, etc.
10.- AUX INPUT: line level inputs. Allow the connection of audio sources, 2 x RCA connectors.
11.- MIC/LINE INPUTS: microphone/line inputs which use a combined XLR and 6.3 mm jack connector,
accepting balanced and unbalanced microphone signals and balanced electret condenser microphones
that require 24 V phantom power supply, present in the pins 2 and 3 of the XLR connector. They accept
high level line signals, balanced or unbalanced, coming from mixers, CD, tape, tuner, etc.
Select the appropriate gain using the AIN control, being careful to set the volume controls to minimum
to avoid damage.
