The Bogen Volume Controller Attenuator for Self-Amplified Speakers BUFEX Buffer-Expander is designed to remotely control the volume of a network of speakers. Attenuator, Buffer, and Speaker Expander for Self-Amplified Speakers in one single device.
This system allows emergency announcements to be heard through all speakers in a system even if the volume control knob setting is set low or off. A PCB-mounted bypass trim control adjusts the volume when in bypass mode with a maximum of 12 dB of attenuation. The BUFEX fits into a single gang electrical box.
The BUFEX also provides output buffering for up to 150 self-amplified speaker inputs and allows speaker system expansion of existing 100V, 70V, or 25V central amplifier systems.
