AudioControl AC-BT24 Review: Specifications, Installation and Comparisons
Quick summary: the buying decision
Add the AC-BT24 if you want to tune an AudioControl processor from a phone or tablet (DM Smart DSP app on iOS and Android) or stream aptX HD Bluetooth audio straight to it. It only works with AudioControl products that have an Option Port, so check the compatibility list below before ordering.
AudioControl AC-BT24: what it is
The AudioControl AC-BT24 plugs into the Option Port of AudioControl DSPs and DSP amplifiers to add high-definition Bluetooth streaming with aptX HD and wireless set-up through the DM Smart DSP app. It also gives wireless control of the DM-RTA through the DM-RTA app.
AudioControl lists the AC-BT24 as compatible with the DM-810, DM-608, D-6.1200, D-5.1300, D-4.800 and DM-RTA. It is powered by the Option Port, so it needs no extra wiring.

Streaming and tuning at the same time
With aptX HD devices the AC-BT24 streams 24-bit / 48 kHz audio with low latency. You can stream audio and programme the DSP at the same time, which makes it easy to tune with your own reference tracks from the driver's seat.
Installation
Plug the module into the Option Port on a compatible AudioControl processor or amplifier; it draws power from the port. Mount the host unit where the Bluetooth signal can reach the cabin, because metal panels and long distances reduce range.
