Thank you for purchasing this product. Before using the product, read through the user manual to ensure that you will use the product correctly. Please keep this manual for future reference.

Features

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 the 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 the 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, a switch logic output for controlling remote devices, and a lock tab to hold the 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 the microphone is inserted, securely holding it in place until tab is manually released by the 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.

Connection procedure

Connect the output terminals of AT8657/LED-S to a device that has a microphone input (balanced input) compatible with a phantom power supply, 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.

audio-technica Flush-mount Microphone Description

AT8657/LED-S requires 24-48 V DC phantom power.

Speciﬁcations

Output impedance	360 Ohms
Switch logic	High (+5V DC) when pressed;

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). The 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).
