DSP mixer

The Stingray is an all-in-one rack-mountable DSP device that serves as an easy to install solution for integrated rooms. It utilizes Phoenix Audio’s proprietary distributed array technology, supporting multiple interfaces, inputs, and offers a built-in amplifier.

Daisy Chaining

The ability to connect multiple units together to work as a single system. This enables larger coverage and scalability.

Dual Connectivity

Offering multiple interfaces in a single product. This feature allows the use of one product in a room that requires multiple connectivity options (audio and video conferencing).


The ability to connect two calls from different interfaces simultaneously, making your video conferencing participants able to speak with your audio conferencing participants as well as yourself through your device.

Direction Finding

The ability to recognize the direction of the person speaking in the room.


The ability to steer the directionality of the device’s microphones. Beamforming improves noise and echo cancelling as well as the overall quality of the device’s pickup.  This feature works in conjunction with direction finding.

Wall Mountable

This product supports a mounting system that allows you to mount it directly to the wall (most commonly behind the monitor).

Noise Cancelling

Filters out ambient room noise such as air conditioning and background office or traffic noise

Acoustic Echo Cancellation

Prevents your microphone from transmitting the voice picked up from your speaker

Automatic Gain Control

Automatically adjusts your microphone sensitivity so that you are heard loud and clear regardless of your tone and distance from the device


Improves audio pick up quality in reverberant rooms with hard reflective surfaces such as exposed, concrete, marble, or glass walls and ceilings


Steering or directing an audio beam to pick up audio only from the direction of the person speaking, while canceling noise from all other directs
