The GDS® Audio™ amplified audio breakout and speaker can be hardwired into the cab of your vehicle – with no batteries required for power. The audio breakout feature also allows for the inclusion of a PTT (push to talk) microphone (not included) or headset (not included) to enable half or full duplex conversation depending on the device and call solution being used. An adjustable knob allows for up to 99dB of amplified audio feedback from your device, and the speaker includes built-in overcurrent, short circuit, and overvoltage protection. As part of the GDS® Ecosystem™, the speaker can be mounted to any GDS® vehicle dock using the RAM® short bracket adapter or RAM® standard bracket adapter. Each bracket includes hardware to mount the speaker to the bracket, as well as the bracket to your GDS® vehicle dock.
