WIRING OUTPUT CONNECTORS
Before making any output connections, ensure the power cord is disconnected from the amplifier and carefully review the total impedance for loudspeakers
connected to each amplifier output. If multiple loudspeakers are connected to an output (i.e., in series, parallel, or series-parallel), be certain the total system
impedance is within the allowed specification for the output. See the “Specifications" table below for supported load specifications.
JBL recommends using two-conductor or four-conductor, heavy gauge speaker wire up to 12 AWG.
Speaker outputs provide connection for up to four pair of stereo speakers (eight speakers total) to the
DA850 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 from 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.
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.
