Bogen - BUFEX BUFFER EXPANDER UPC 765368450941

The BUFEX is a continuously variable speaker attenuator 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.
