Please keep this manual for future reference.
Connect e a the output terminals of to a dAT8657/LED-S vice that hava
microphone input (balanced input) compatible with a phantom p er supplow y,
a switch logic control output and a LED logic input . The input / output connectors are
XLRM-type with polarity as shown in the figure below.
• Flush-mount microphone socket for the AT846C / AT846O or any phantom-powered
gooseneck microphone with a 3-pin XLRM-type output and a base diameter no
greater than 21 mm
• Mounts unobtrusively in tabletops
• Switch logic output permits control of remote devices from built-in capacitance switch
• Integral, phantom-powered, Green/Red 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

■Description
The AT8657/LED-S 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-S 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.

■Installation and Operation
The AT8657/LED-S requires 24-48V DC phantom power for operation.
Output is low impedance (Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin
1 is ground (shield). Output phase is "Pin 2 hot" - positive acoustic pressure produces
positive voltage at Pin 2. Switch logic output appears between pins 1 and 4. LED logic
input appears between pins 1 and 5.
The microphone socket should be installed on a flat, unobstructed mounting surface.
The AT8657/LED-S should be mounted to a tabletop using the included isolators in
order to dampen surface vibration. To mount the socket with the isolators, a 35 mm
hole is recommended. Place the isolators on either side of the hole to achieve
mechanical isolation from the mounting surface.
The AT8657/LED-S's capacitive-type touch-sensitive switch allows the user to trigger
a function on an external device: Switch logic output is High (+5V DC) when pressed.
Low (0V DC) when not pressed.
The LED indicator ring lights red when logic high (+5V DC) and green when logic low
(0V DC).
