Signal and Speaker Connection Considerations
When connecting your stereo and speakers to the amplifier, observe the following considerations:
• Each set of zone speaker terminals on the amplifier is paired to the RCA inputs for that zone.
• Each channel supports a nominal 4 Ohm speaker load impedance, and a 2 Ohm minimum speaker load
impedance.
• You can connect two speakers in parallel on a single channel, and the combined impedance must be
greater than the 2 Ohm minimum load impedance (
Connecting Multiple Speakers or Subwoofers In Parallel,
).
• You can connect either a zone line out or a subwoofer line out from the stereo to any of the zone RCA inputs
on the amplifier.
• You should use the proper gauge speaker wire noted in the
Speaker Wire Gauge Guide, page 8
speakers and subwoofers to the amplifier.
• You should observe the zone and polarity markings for each channel when connecting speakers to the
amplifier. For example, Z1L indicates the ZONE 1 left channel, and Z1R indicates the ZONE 1 right channel.
• If you are connecting a combination of speakers and subwoofers to the amplifier, you should connect the
subwoofers to ZONE 2 or ZONE 4 as illustrated below. These zones have dedicated BASS BOOST controls.
• You can connect a subwoofer to a single channel, but you should connect it using bridge mode to get the
best performance (
Connecting a Speaker or Subwoofer in Bridge Mode, page 10
).
In the following example, 4 Ohm subwoofers are connected to the bridged terminals for ZONE 2 and ZONE 4,
and pairs of 4 Ohm speakers are connected to the right and left channels for the other two zones.
In this example, you must connect the subwoofer line out from the stereo to the ZONE 2 and ZONE 4 RCA
connectors on the amplifier (using RCA splitters), you must connect the two zone line out connectors from the
stereo to the other two zone RCA connectors on the amplifier.
