Bogen AT35A 35W Attenuator, Mounts in Standard Single or Double Electrical Box

Control speaker output where it matters most — at the point of use. The Bogen AT35A 35W attenuator is a rugged, wall-mountable pro audio controller that lets installers and facility managers set precise volume levels for 25V or 70V speaker networks without altering amplifier output settings. With a 35W power rating and ten attenuation steps (plus Off), the AT35A provides predictable 3 dB level reductions (two lowest settings at 6 dB) so paging, background music and emergency announcements remain intelligible and consistent. Its compact housing mounts in a standard single/double electrical box and uses straightforward hard-wire connections for quick deployment in schools, retail, offices and security installations. Because it controls zones at the wall, the AT35A simplifies surveillance and monitoring audio requirements — perfect for integrated security and public address systems. Backed by Bogen’s reputation and a 2-year limited warranty, this attenuator reduces call-backs and speeds installs. Add the AT35A to your next paging, monitoring or security audio project for reliable, on-site volume control.
