SYSTEm AppLICATIONS
Home Theater Plus Second Zone
The multizone system shown in
Diagram 22
features the M8 when used to add multiple rooms of amplified audio to the Zone 2
OUT on an A/V Receiver, (in this case a Proficient M80). This system is a two zone system, meaning two different sources can be
played at the same time. The home theater is Zone 1 and can select any source connected to the M80. The M80 features a Zone 2
OUT that can output line level audio and composite or S-Video. (For purpose of example only the Zone 2 audio connections will
be detailed here. Please refer to the
M80 Installation and User Guide
for additional information.)
Note:
The M80 allows connection of 5.1 or 7.1 surround speaker configurations. Those speakers are not shown in
Diagram 22
.
Please refer to the Owners Manual if using another brand receiver for information on connections/limitations.
M80 Source Connections
Audio/Video sources are connected to the M80 Receiver in a normal manner. In the theater zone, they are selected and played in
a normal manner using the front panel controls or a remote control. Sources are typically selected and controlled in Zone 2 using
an IR Remote via an IR repeater system. The selected sources can be the same in both zones or a different source in each zone. The
source selected by Zone 2 will play to all rooms in Zone 2.
The M80 features analog and digital audio and video inputs. Any of these inputs can be selected by the home theater. Zone 2 can
only select analog audio inputs, therefor any source that is to be played in Zone 2, must have analog audio connections to the
M80.
Bus In
The M8 is connected to the M80 Receiver Zone 2 OUT. The Zone 2 OUT is a fixed line level audio output that is connected to the
M8 BUS IN. The M8 BUS IN audio signal will output through any channel(s) that are set to BUS L (left) or BUS R (right).
1.
Connect the M80 Zone 2 OUT to the M8 BUS IN.
2.
Set the Channel Input switches for all channels that are to output the BUS IN to BUS L (left) or BUS R (right).
Bus Loop
Source selection and audio processing for the home theater zone and Zone 2 are completely independent. The M80 Zone 2 OUT is
a dedicated line level audio output. It is not necessary to feed the BUS LOOP back to the M80.
The BUS LOOP can be used to add additional M8 amplifiers for additional rooms of amplified audio to Zone 2. Up to five M8s can
be connected in this manner.
1.
Connect the M8 BUS LOOP to the next M8 BUS IN. Repeat to connect up to five M8s (20 amplified rooms).
Power Mode Switch
For convenience, the M8 can be setup to turn ON/OFF automatically when the M80 is turned ON/OFF. There are two automatic
power modes: Audio Sensing (Auto ON) and Voltage Sensing (Trigger).
Audio Sensing
Requires no additional connections. When the M8 detects audio on any input it will automatically turn all channels ON.
1.
Set the Power Mode Switch to Auto ON.
2.
Set the Front Panel ON/OFF switch to the ON (in) position.
Voltage Sensing
Requires connection of a 3-30 V AC/DC control voltage. For the example shown, the M80 Trigger OUT (if not used for M80 sub-
woofer trigger) or a 12V power supply, connected to the switched outlet on the M80, can be connected to the M8 Trigger jack.
1.
Connect a power supply to the M80 switched outlet. Connect the power supply to the M8 Trigger jack, (maintain
proper polarity); or connect the M80 Trigger OUT to the M8 Trigger jack with a mono mini-mini cable.
2.
Set the Power Mode Switch to Trigger. Set the Front Panel ON/OFF switch to the ON (in) position.
Channel Mode/Speaker Connections
Set the Bridged switches to OFF for normal mode. Connect speakers using the normal mode/multiroom configuration.
