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 and nuts are not included).
Installing a DA series amplifier in a rack:
1. Attach the rack ear brackets to the sides of the amplifier using the provided
machine screw fasteners into the threaded holes.
2. 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.
