The ATLASIED C-T4-B is a wall-mounted volume controller designed for 70-volt distributed audio systems. It provides local level adjustment at the zone or room level, allowing installers to balance audio output without returning to the amplifier rack. The C-T4-B ships in a black finish, making it a clean fit for commercial and institutional spaces where aesthetics matter alongside function. Audio-visual integrators, low-voltage electricians, and commercial sound contractors are the primary trades that specify and install this type of controller.
The C-T4-B is suited for commercial, hospitality, retail, and institutional installations that use constant-voltage 70-volt audio distribution. Typical deployments include background music systems in restaurants, lobbies, offices, and multi-zone paging setups where individual room control is required. It mounts in a standard single-gang wall box, keeping the installation straightforward on new construction or retrofit projects.
Designed as an OEM-style volume control for 70-volt distributed audio systems; confirm compatibility with the specific amplifier and transformer tap ratings used in the installation.
Installation is typically performed by a licensed low-voltage contractor or audio-visual integrator familiar with 70-volt audio distribution. De-energize the amplifier and associated circuits before making any wiring connections. Follow local low-voltage wiring codes and the amplifier manufacturer's guidelines for total tap load. Verify the transformer tap setting on any speakers in the zone to ensure the controller operates within the rated load range.
