Description

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.

Features:

  • Continuously variable attenuator
  • Drive up to 150 self-amplified speaker inputs
  • 100V, 70V, 25V, and page port level selectable input
  • Bypass trim control for emergency paging (12 dB of preset control over level of bypass announcements)
  • Mounts in a single gang electrical box
  • Rugged and attractive stainless steel plate with engraved lettering
  • Easy and secure terminal strip connections
  • Two-Year Warranty
