Flush-mount Microphone Socket

AT8657/LED
  • Flush-mount microphone socket for any phantom-powered gooseneck with a 3-pin XLRM-type output and a base diameter no greater than 21mm
  • Mounts unobtrusively in tabletops
  • Switch logic output permits control of remote devices from builtin capacitance switch
  • Integral, phantom-powered, Red/Green LED indicator ring
  • Operates on 24-48V DC phantom power
  • 3-pin XLRF-type connector for microphone, 5-pin XLRM-type connector for output
  • Lock tab in socket case automatically locks microphone in place, holding it there until tab is manually released by user
  • Isolators provide mechanical dampening of mounting-surface vibration
  • Low-profile design with low-reflectance black finish for minimum visibility

    The AT8657/LED flush-mount microphone socket features a capacitive-type touch-sensitive switch, Red/Green LED indicator ring, switch logic output for controlling remote devices and a lock tab to hold microphone in place. The socket is equipped with a three-pin XLRF-type in, and a five-pin XLRM-type output connector.

    The AT8657/LED requires 24-48V DC phantom power for operation. The electronics in the socket take up to 30 seconds to stabilize after power is applied; during this start-up period, some sonic disturbances may be heard upon switching if the system is "live."

    The touch-sensitive switch can be used to trigger an external device.

    The lock tab, located in the socket case, automatically engages when microphone is inserted, securely holding it in place until tab is manually released by user. The output of the socket is a 5-pin XLRM-type connector.

    Isolators are included with the unit for mechanical isolation from the mounting surface. A retaining ring is also included for use with gooseneck microphones. The socket is enclosed in a heavy-duty die-cast case. The low-profile housing has a low-reflectance black finish.
