INPUT PRIORITY MODIFICATION
The priority function automatically attenuates the level of the inputs with less priority so that the input with
greater priority can be clearly heard.
The system has 4 priority levels (1 maximum priority, 4 minimum priority) for any of the inputs. These can
be set from the front panel recorder/player module. The inputs with the same level of priority will be played
simultaneously.
To access the priority change menu:
-
Press and hold the MODE button for 2 seconds
-
Select the entry you want to modify using the buttons
Change the priority level using the VOL+/VOL- buttons
-
NOTE: the M-64 microphone has a PRIORITY switch located on the rear panel. If this control is activated
it automatically assigns maximum priority (priority 1) to that microphone in the system. Otherwise, it will
maintain the priority assigned in this MP3 module.
NOTE: shortcircuiting the MZ-648 MSG PRIORITY terminals on the rear panel of the amplifier, maximum
priority is assigned to playback messages on the MZ-648 microphone.
CONNECTION
Make the connections with the amplifier and all the components of the system switched off and disconnected
from the power supply.
Connect the microphone level or line level audio sources using INPUT 1 to INPUT 4, regulating the gain in the
inputs. If connecting condenser microphones, select the phantom power supply (24 V) on the corresponding
input.
If your system is composed of MZ-648 microphones (maximum 3), connect them using the port MZ-648
PAGING MIC INPUT 2.
If your system is composed of M-64 microphones (maximum 3), connect them using the port M-64 PAGING
MIC INPUT 1. And switch on the PHANTOM +24V power supply of INPUT 1.
Connect the line level audio sources using the AUX 1 and AUX 2 inputs.
Connect the 100 V line speakers to the Z1-Z6 zone outputs. For this connection, please note that you must
make parallel connections.
NOTE: the maximum power of each of the zones is 120 W RMS and the total sum of the power of all the
loudspeakers must not exceed the maximum power supplied by the amplifier, 480 W RMS.
A recording device can be connected using the REC output on the rear panel of the amplifier. The recording
volume depends on the volume of each input.
The amplifier can operate in dual mode, for which it must be connected to an external amplifier which will
playback the microphone paging and not interrupt the background music in the rest of the zones. To do this,
you must connect the PAGING OUTPUT output of the MPZ-6480RGU amplifier to the input of the external
amplifier. Then connect the 100 V line output of the external amplifier to the PAGING AMP 100 V INPUT input
of the MPZ-6480RGU amplifier.
Once the connections have been made according to your needs, connect the devices to the power supply
and switch them on.
