Audio Technica ES947LED touch-sensitive capacitive switch and LED status ring

Introducing the ES947LED, the new LED-equipped version of the Engineered Sound ES947 table-mount boundary microphone. The ES947LED features a touch-sensitive capacitive switch and LED status ring.

The cardioid condenser ES947/LED increases usability with a new toggle switch and LED status ring - which displays red when muted and green when switched on. The new LED-equipped version of the highly respected ES947 also features improved sensitivity and sound-to-noise ratio, perfectly suited to todayʼs digital matrix mixers.

The ES947/LED is available in black and white.

• Heavy die-cast case and non-slip silicone foam bottom padsminimize coupling of surface vibration to the microphone

Description

The ATND8677 is a Dante-enabled microphone desk stand for use with any gooseneck microphone with a three-pin XLRM-type output connector. The desk stand is designed for surface-mount applications such as high-quality sound reinforcement, conferencing, distance learning and other demanding sound pickup applications.

The desk stand features a touch-sensitive capacitive-type user switch with integral red/green LED status indicator. In Local mode the user switch mutes and unmutes the microphone. It can be set to toggle between live and muted audio (toggle on/off), to permit live audio only while the switch is pressed (press to talk), or to mute the audio while the switch is pressed (press to mute). In Remote mode the user switch can be used to trigger functions on compatible Dante-enabled devices, such as a video cameraʼs pan/tilt or a roomʼs lighting preset. While in Remote mode the desk standʼs audio output is controlled remotely. An integral 80 Hz low-cut UniSteep® filter provides easy switching from a flat frequency response to a low-end roll-off. The roll-off position reduces the pickup of low-frequency ambient noise (such as traffic, air-handling systems, etc.), room reverberation and mechanically coupled vibrations. A three-position input gain level selector permits trim adjustment to accommodate louder and softer voices. The desk stand provides 12V DC phantom power by default, which can be switched off and on.

The gain, low-cut UniSteep® filter, red/green LED status indicator and phantom power can all be controlled locally or remotely via third-party software.* Recessed buttons on the bottom of the desk stand allow user to configure the desk stand settings locally. Audio, low-cut, gain and phantom power settings can be locked in Local mode by pressing and holding the lock button. This lock will prevent end users from adjusting the settings. Default settings for the stand are as follows: audio toggle on/off (with audio muted at power up), low-cut filter off, +30 dB input gain, phantom power on.
