Details

The BUFEX Buffer-Expander Volume Controller Attenuator for Self-Amplified Speakers (-1CU) by Bogen Communications is a continuously variable Attenuator, Buffer, and Speaker Expander for Self-Amplified Speakers that can remotely control the volume of a network of speakers.

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. The BUFEX includes a bypass function that can override the volume control knob setting when activated by a contact closure or open collector output.

This 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.
