Tone controls (7-8) provide a gain/attenuation of ±15 dB for each one of the LOW and TREBLE bands.
6.5. Output volume adjustments
Output volume can be adjusted for each zone by two controls:
The VOL rotary knob on the front panel when the associated REM/LOC switch is in Local position (released)
The Volume rotary knob on the remote wall panel (if installed) when the associated REM/LOC switch is in
Remote position (engaged)
The active source can be selected for each zone by two controls:
The SOURCE rotary selector on the front panel to select one equipment input (1 to 4) or none (OFF)
The INPUT rotary selector on the wall remote panel (if installed) when the front panel associated rotary
selector (SOURCE) is on Remote position. Available options are also input sources 1 to 4, or none (OFF)
6.6. Wall remote control connection
The wall remote controls are connected to the MZ54 by means of a standard CAT5 cable terminated on both ends
with RJ-45 connectors: insert one of them in a REMOTE port on the back panel (ZONE 1, ZONE 2, ZONE 3 or
ZONE 4) and the other in the RJ-45 port of the remote control.
