1. Bus 12VDC Trigger In/Out
The trigger input is a handy feature when
connecting the amplifier to an automated audio
system, The 3.5mm mini- plug jack will accept a
3-30V AC/DC output from another device, or
from a separate power supply.
The Bus 12VDC Trigger In is used to activate all
zones that are using the Bus Input and disables
other zone triggers or signal sensing on those
zones when it is used. When the Bus 12VDC
Trigger is used, all Bus-controlled zone LEDs will
be blue and active.
If the Bus Trigger In has 12V applied to it, only
the 12V Bus Trigger Out will have 12V and the
Zone Trigger Outputs will not.
2. Bus Inputs/Outputs
The MZ-series amplifier has two common or BUS
inputs that receives audio signals from standard
line-level audio sources that can be used to
connect a single source to multiple zones. The
BUS line outputs are passive pass through the
corresponding of the Bus Inputs and can be
used to daisy chain the source to other
amplifiers in the system. Be sure to use high
quality RCA cables that feature low impedance,
shielding and high quality connectors.
3. Input Selection Switch
Each channel is capable of delivering the source
from many inputs, select the BUS IN (1 or 2),
OPTICAL IN, and Local LINE IN for the output.
The selection for these inputs is done via the
Input Selection switch associated with each
channel. Select the desired source input. Set the
Input Selection switch to BUS IN (will play source
connected to the BUS 1 or BUS 2 input),
OPTICAL IN (will play source connected to the
OPTICAL input) or LINE IN (will play source
connected to that channel’s LINE IN).
CAUTION: Only change switch positions when
the amplifier is turned off.
4. Optical Input
For components with Digital Optical Outputs sending
digital audio signals to each zone
5. Line Input
Local input for zone (plays only on that zone’s outputs).
Use for instances where the zone will always play a
different source than other zones. Set the Channel Input
Selector switch to “Line In” to use this input.
6.12VDC Trigger In/Out (Each Zone)
The Zone 12V Trigger In is used to activate a specific zone.
The Zone Trigger Out can be used to trigger other 12V
devices. The delay and audio sensing are bypassed when
the 12V Zone Trigger Input is used. When a Zone Trigger
is active, the zone LED will be blue. If no voltage is present
in the Zone Trigger, the Zone LED will be off.
7. Speaker Outputs
The MZ-Series amplifier uses high quality Phoenix style
connectors for the speaker connections. Use 14-18 gauge
stranded two-conductor loudspeaker wire. Ensure that at
least 2 inches of each conductor are separated. Strip
away 1⁄4 inch of insulation from each conductor. Connect
the appropriate conductor to each screw terminal,
observing correct polarity. Also, please observe proper
speaker wiring when bridging channels.
The minimum speaker impedance is 4 ohms for Stereo
Mode and 8 ohms for Bridge Mode.
8.Stereo/Bridge Switch
Select whether a pair of left and right output channels are
individual or bridged together for a more powerful mono
channel, the Bridge Output mode is ideal for powering
larger speakers or speakers on long cable runs.
