Hardware Setup
CONNECTING AUDIO INPUTS
JBL recommends using pre-built or professionally wired unbalanced cables (single-ended plus shield). The
DA series amplifiers accept line-level audio connections at the RCA input connectors.
When the amplifier is used as a multi-zone amplifier, each channel can be provided with a dedicated input
signal. The signal from this input will be available on the corresponding speaker-level output.
Alternatively, each zone can be linked individually to the GLOBAL IN/ZONE INPUT 1.
Local inputs are grouped and identified in pairs, with a shared output level control.
Note that for BRIDGE/MONO operation, a stereo input will be appropriately summed to mono and outputs
can be used in either Bridge outputs or single channel pairs.
WIRING OUTPUT CONNNECTORS
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 "Specifications" on page 13 and 14
for supported load specifications.
JBL recommends using two-conductor or four-conductor, heavy gauge speaker wire up to 12 AWG.
For low-impedance loads, refer to the table below and select the appropriate size of wire based on the
distance from amplifier to speaker.

Up to 25 ft. (7.6m)
16 AWG
26-40 ft. (7.9-12.2m)
