Description:
Digital audio mixer in 1U metal housing with 6 micro/line inputs and switchable input for CD/AUX/USB with treble and bass controls as well as 6 outputs.
Each input provides many features: analog and digital gain, anti-hum filter, lowpass/highpass Butterwoth filter, 5 biquads parametric equalizer, mute, volume, noise gate, automix.
A matrix within the audio mixer, provides the capability to route each input signal to specific outputs and adjust their node levels as needed.
Automix employs a sophisticated algorithm, carefully engineered within this digital mixer, to seamlessly manage input selection. This intelligent system dynamically adjusts threshold levels to ensure optimal performance, even in challenging acoustic environments with fluctuating background noise.
Each of the 6 outputs are equipped with 8-biquads parametric and a 31 Band graphic-equalizer, level adjustment, noise gate, compressor and limiter.
Additionally, the DMX 66 features two outputs with independent anti-feedback functionality, each employing five notch filters for precise feedback suppression.
By using the AVE Mixer User Control PC-Software all function adjustments of the parameters can be made as well as creating and storing the 20 presets via Ethernet connection.
Remote control by Ethernet interface.
In addition to the basic functions, the DMX 66 offers the possibility of a built-in web interface for LAN remote control via browser as well as the possibility to stream the audio signal over the internet via integrated Icecast streaming media server. Additionally, DMX 66 embeds a web player allowing users to listen to audio streams directly within the browser.
The digital audio mixer DMX 66 features a built-in USB MP3 player and a Bluetooth receiver, allowing for seamless music playback from various devices.
6 potentiometers on the front panel for the volume control of micro/line, a potentiometer and a treble and bass control for CD/AUX/USB (with display) offer a wide range of settings to the user. With two encoders the user can choose the presets and control the master volume. The settings are shown on a clear display (2 lines with 20 characters).
Digital Audio Mixer DMX 66 is officially licensed to use the Powered by Raspberry Pi Logo and featured in the Powered by Raspberry Pi Catalog.
