■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).

感谢您购买本产品。在使用产品之前，请全文浏览本用户手册以确保您将正确地使用

本产品。请妥善保存本手册，以供将来参考。

AT8657/LED-S 是一套嵌入式，用于桌面安装设计的话筒插座，具有轻触式开关作

外部设备控制，另外整合了一个环型LED状态显示灯，能由外部控制绿色或红色的

灯号显示。该插座还具有自动锁定话筒开关，输入端为3针卡农母座；而输出端为5

针卡农公头。

插座需要直流24V至48V幻象供电工作，插座中的电子电路在通电后需经 30 秒才能

稳定; 在这初段时期，如果在系统上开关按钮，可能会听些声波的干扰。

轻触式的开关功能，配有一个可编程的电容式轻触开关作远程设备的控制，使用户

只需触摸按钮，便可以轻松地控制外部设备。

该插座还具有锁定开关，当话筒完全插入时可以自动锁定话筒，以避免被人拿取，

只有作出手动释放后，方能除下话筒。

插座输出端为5针XLRM卡农插头。

每个插座都配有一对防震橡胶隔离环和一套金属固定环 (配合鹅颈话筒使用)，以减

低安装面上的震动噪声。外壳为金属结构，表面涂上低反光黒色涂层。

将AT8657/LED-S 的输出端子连接到具有兼容幻象电源的话筒输入 (平衡输入) 的设

备，以及把开关逻辑控制输出及LED输入连接到相关设备。输入/输出接口是 XLRM

型接口，其极性如下图所示。

■安装与操作

AT8657/LED-S 内置的控制电路，需使用直流 24V 至 48V 幻象供电工作。

低阻抗的平衡音频输出，音频信号以卡农公头的2号及3号针脚输出，1号针脚则为

地线(屏蔽)连接。输出相位将以正相位电平设于2号针脚上。开关按钮的逻辑输出

连接于1号与4号针脚中，LED 输入控制则应用于1号与5号针脚中。

话筒插座应安装在一个平直及无阻碍物的平面上。

AT8657/LED-S 插座应使用附属的防震胶安装于桌面上，以隔离桌面上震动。在与

防震胶一起安装时，需要开出直径 35mm 的圆孔，而防震胶需要前后两端同时安

装于平面上。

AT8657/LED-S 插座的电容式轻触开关，可容许使用者用于控制外部的其他设备：

当按下时，开关逻辑输出为高电位 (直流+5V)；而无按下时,为低电位 (直流0V) 的

开关逻辑输出。

LED 显示灯在高电位输入时(直流+5V)为红色；低电位输入时(直流0V)为绿色。
