ing amplifiers all firmware must be the same on all
amplifiers
3. Zone setting. The units all ship with zones 1,2,3,4
already setup.
To add additional amplifiers to a stack the zones
must be changed on the additional amplifiers. If
there are zone duplications in a stack of amplifiers
the zones with the same number will exactly mirror
each other's operation.
To change an amplifier zone follow the following
steps.
·
Do not connect the expansion bus cable.
·
From the front facia rotate the Knob to select the
appropriate amplifier ­ turn it on, and then select the
"More" menu (right arrow). Scroll through the menu
and select "Set Zone" and change to the required
assignment pushing the Knob to set.

Features
Thank you for purchasing an Integra MZA-4.7 Multi-Zone Amplifier.
Please read this manual thoroughly before making connections and plugging in the unit.
Following the instructions in this manual will enable you to obtain optimum performance and listening
enjoyment from your new Multi-Zone Amplifier.
Please retain this manual for future reference.
Multi-Zone, Multi-Source, Video Switching
The MZA-4.7 has four separate preamplifiers and ampli-
fiers, providing 4 zones of independent yet integrated
control.
There are seven stereo sources (S1 - S7) and an eighth
mono source (S8) typically used for paging applications.
Each zone has an eight-source composite video switcher,
so monitor screen's in four different rooms may display
any of the eight sources (S1 - S8).
Preamplifiers and Outputs
Each zone has bass, treble, balance and loudness control.
These are accessed either from the front panel or IMC
(Integra Music Center) program.
The preamplifier output volume may be independent of
the amplifier volume, or made to track the amplifier with
an adjustable offset (± 20dB). The tracking feature is
ideal for passive subwoofer control, while the indepen-
dent volume feature is useful for limited control in
closecoupled rooms.
A useful protection feature is "Maximum Volume limit-
ing." This limits the maximum volume of either the
amplifier or preamplifier.
Amplifier Power, Protection, and Clipping
Indicators
50 Watts RMS per channel into 8 ohms, capable of driv-
ing into 6 ohms.
The amplifiers are protected against short-term output
shorts.
The front panel zone indicators will flash red when the
zone amplifiers are overdriven into clipping.
Thermal Control
There are three progressive levels of thermal control:
· An internal fan is turned on to aid cooling.
· The amplifier volume is reduced 20dB.
· The amplifiers are shutdown until the temperature
reduces below the first level.
Care should be taken to ensure adequate ventilation ­ see
"Important Safety Instructions" on page 2.
USB, RS232 and IR Control
The MZA-4.7 may be controlled and monitored via
either the front Panel USB or rear panel RS232 serial
interface.
In multi amplifier installations where the amplifiers are
interconnected using an expansion bus cable, only one
USB or RS232 connection is required to control the
stack of amplifiers.
A MZA-4.7 may receive IR directly from the front panel
receiver or via the two "Controller Interface" connec-
tions.
There are zone specific IR commands and also a set of
global IR commands.
The commands are: ON, OFF, Standby (toggling), Mute,
Amp Volume Up, Amp Volume Down, Pre Volume Up,
Pre Volume Down, Source Selects, On with Source Spe-
cific commands.
The Global commands also include PRESET1 - PRE-
SET 6, Alarm Enable, Alarm OFF, and 5 minute Sleep.
Real Time Clock
The MZA-4.7 is equipped with a real time clock.
The amplifier may be set up to function as an alarm
clock, so that at 6.30am in the morning 5 days a week,
the master bedroom zone could be made to turn on,
select tuner, and go to a specific volume. Multiple
Alarms are feasible (max of 6) However the Alarm
Enable & OFF commands act upon all programmed
Alarms.
The clock continues to operate typically > 48 hours with-
out power ­ more than enough to keep the time current
during lengthy power outages.
IR Emitter Ports
There are 4 Buffered IR emitter Ports.
Two IR ports have routing, and are linked to their respec-
tive "Controller Interface" ports. These ports control
zone specific source components. Two IR ports are the
sum of both IR sources; these control the All zone source
components.
Presets and Paging
There are six amplifier presets and a page preset.
Presets 1 - 6 are momentary and cause the amplifier to go
to a predetermined setup, i.e. standby, volume & source
selection.
The presets may also be programmed with event sched-
uling, and are used by the alarm clock.
The "Page Preset" mode is for paging applications and is
invoked by a contact closure between the "0V" and the
"PG" terminals. When the contact closure is released the
amplifier zones return to their previous states.
Zone Linking
A zone may be programmed to link one other zone. Zone
linking ties the source selection together. It may also tie
the volume, and standby.
This is useful for closely coupled audio areas where it is
