Attenuator for DC lines RCF AT 40T

The RCF AT 40T is a universal volume control for 100 V line array systems that provides precise sound level control for a group of loudspeakers with a total power output of up to 40 W. With its 6-position selector (5 levels + off) and built-in isolation transformer, the AT 40T makes it easy to control the sound in sound systems.

The device is equipped with a 24 VDC relay that allows you to bypass the volume control for paging calls or switch to a second 100 V line that is not adjustable. For emergency announcements, it is possible to work with 3-wire lines, which provides additional functionality.

The RCF AT 40T can be mounted on any support frame for home or office electrical systems. The set includes three interchangeable handles in different colors (white, silver and anthracite), which allows you to choose the optimal look to match the interior.

For installation, the transformer can be placed inside a wall or flush-mounted box, if the available space allows it. Thanks to its reliability, ease of use and stylish design, the RCF AT 40T will be an excellent solution for adjusting the volume in audio systems of any complexity.
