4.2 Connecting to speakers
CDA-4D can power two stereo output of audio
and has phoenix-style terminal blocks for speaker
connections. Speakers can also be wired to bridge
channels to increase the power available to
the speakers.
To connect stereo speakers:
1. Connect speaker cable to the phoenix
connector and reinsert into the amplifier,
see Diagram 9.
The common signal of these speaker outputs
must not be connected together or to any
other common signal. Do not connect the 1
– and 2 – (negative) terminals together. Doing so will
result in a fault condition and the amplifier will either
shut down or not work properly.
Check the polarity of the speakers and
wires before connecting to the amplifier.
To connect bridged-tied load speakers,
see Diagram 10:
1. Select BRIDGE-TIED LOAD in the Product
Configuration Page.
2. C terminal from the speaker to
the + terminal of the right channel (R).
3. Connect the - terminal from the speaker to
the - terminal of the left channel (L) on
the amplifier.
The two terminals for a bridged pair of speakers
area marked by + BRIDGE –.
In bridge mode both amplifiers in the zone combine
to make a mono output of double the power.
The minimum load impedance in bridge
mode is 8Ω. Connecting 4Ω loads may
result in lower output power, distortion
and overheating.
