Speaker outputs provide connection for:
Up to four pair of stereo speakers (eight speakers total) to the DA850
Up to eight pair of stereo speakers (sixteen speakers total) to the DA1650
Connection to speakers is provided via phoenix-type connectors that accept bare wire terminations. The
connectors are grouped in pairs with one connector each for pair. Each pair consists of four wire
terminations: positive (+) and negative (–) for the Left channel and positive (+) and negative (–) for the
Right channel. To attach speaker cables to the phoenix connector, strip approximately ¼” of insulation off of
the end of the positive and negative leads of the cable and insert the bare ends into the corresponding
position of the phoenix connector, tightening the screw terminals on top to secure the termination. Repeat
this procedure for each speaker.
Do not connect the L – and R – (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 prior to connecting to the amplifier.
CONNECTING BRIDGED OUTPUTS
1. Set BRIDGE/MONO as needed for each zone by moving the switch to the UP position for that zone.
2. Connect the + terminal from the speaker to the + terminal of the left channel on the amplifier.
3. Connect the – terminal from the speaker to the – terminal of the right channel on the amplifier.
The two terminals for a bridged pair of speakers are marked by + BRIDGED –
In Bridge mode, the pair of amplifier channels in a zone combine to make a mono output of double the
power. When in bridge mode the left and right channel RCA inputs to the zone are active so you can
connect one mono source (Left) or a stereo source (Left and Right) which will sum-to-mono
appropriately.
