The ACR-U is a universal remote level control which can be inserted into any line-level signal path. The ACR-U can be surface or custom-mounted to add subwoofer level control, zone level control, total system volume control, and more to your audio system. Installation is simple and no power is required.

Included is a half meter Cat5e cable. Any Cat5e cable up to 300 feet in length may be used. This means the ACR-U Remote can be mounted far from the ACR-U Hub and all RCA connections can remain short, ensuring low noise and excellent signal integrity.
