Installation
RACK MOUNTING
CAUTION: Before you begin, make sure your amplifier is disconnected from
the power source.
The DA series amplifiers are intended to be installed in a standard 19-inch
equipment rack with the supplied with rack mount ears in a 1U rack space (rack
mount bolts are not included).
Installing a DA series amplifier in a rack:
- Attach the rack ear brackets to the sides of the amplifier using the provided machine screw fasteners into the threaded holes.
- Install into rack and connect cabling.
PROPER COOLING
Air flow is side-to-side.
When using an equipment rack, mount units directly on top of each other. Close
any spaces in the rack with blank panels. (Open spaces will reduce cooling
efficiency.)
Once mounted in the rack, ensure the sides of the amplifier are well
ventilated and fan openings are not obstructed. The rack should be a minimum
of 2 inches (5.1cm) away from the sides of the amplifier .
SURFACE MOUNTING
You can also place a single amp on a solid, stable surface utilizing the
provided feet and fasteners.
Once positioned, ensure the sides of the amplifier are well ventilated and
that the fan openings are not obstructed.
If the system is taken out of use for a long period, disconnect the amplifier
from the mains power supply.
Wiring and Connections
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 by moving the dip switch up for that zone to the ON position.
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 eight pair of
stereo speakers (sixteen speakers total) to the DA1650 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
- Set BRIDGE/MONO as needed for each zone by moving the switch to the UP position for that zone.
- Connect the + terminal from the speaker to the + terminal of the left channel on the amplifier.
- 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
Controls and Adjustments
A AC power inlet and switch
B Bridge/Mono mode – Set the switch to the UP position per zone to enable
Bridge/Mono Mode.
C Link to global input – Set the switch to the UP position to link a zone
to the ZONE 1 INPUT/ GLOBAL INPUT
D Power mode –
ON: Always On
12V: Controlled by 12VDC trigger.
AUTO: Turn on when an audio signal is sensed on the audio input
E Output level control – Provides output level attenuation per Zone pair
