The DR3 Master/Zone Remote Control by Rane is designed for use with their CP66, HAL1, and EXP1 multi-zone audio systems.
It can be used as a zone-specific volume/source control with all three multi-zone systems. However, with the CP66, it can be used as a master remote with individualized level control over each zone.
The intuitive LCD display shows the current level and zone it's connected to. The display has a backlight that turns on when used, then dims when not in use.
The DR3 may be installed in a standard 2-gang electrical box with a minimum depth of 2.25" (5.7 cm). Connects by CAT 5e Ethernet cable up to 1,000 feet.
