Your JBL SYNTHESIS SDA-1700 amplifier is equipped with a thermal protection circuit, which will shut the amplifier off when it gets too hot. If you
experience thermal issues, several factors may be contributing to the problem, including load impedance, air flow and ambient temperature.
To avoid impedance related heating, DO nOt Use any subwoofer other than the recommended JBL SYNTHESIS
Air flow restrictions could be another factor. Always install the amplifier allowing sufficient air flow around the unit, favoring natural convection.
The SDA-1700 works fine in a rack-mounted environment of conventional design. You may have to experiment with positioning, as hotter equipment
below it will raise its ambient temperature. If you experience it thermally cycling, then you may need to move it lower in your rack.
Ambient temperature can also be a factor as a higher room temperature will start the SDA-1700 closer to its thermal limit than a lower room
temperature. If the room is excessively hot, either cool the room or use the amplifier/subwoofer system at a cooler time.

1. Connect a dual-channel RCA patch cable between Left & Right main outputs of the receiver/preamplifier and to the respective INPUT connectors
on the SDA-1700 rear panel, as shown in Figure 5.
NOTE: This configuration applies to receivers with preamplifier outputs or to preamplifier/subwoofer amplifier configurations in which there are two
sets of Main outputs. If the receiver has jumpers from the Pre- or Main-Out to the Amp-in connectors or if the preamplifier has only one set of Main-
Out connectors, a Y-adapter should be used to send the same signal to both the main power amplifier and the subwoofer(s). Tape Out or Record
Out connectors cannot be used.
