Description:
The digital audio mixer Andante 8 offers 8 inputs, 4 outputs, 20 presets and a variety of functions like adaptive automixing, matrix for signal routing, dynamic antifeedback based on notch filters, parametric and graphic equalizer, output delay lines up to 233 m, FFT spectrum analyzer and remote control. All adjustments and parameters can be stored, copied and recalled at any time.
Some functions can be adjusted directly at the unit by using the select-button and the two control knobs. All changes can be easily traced with a clearly arranged view at the menu display. The select-function is present at all microphone/line inputs, matrix and at the outputs with LED indication.
Each of the 8 inputs are equipped with analog gain/phantom power control, anti-hum filter, lowpass/highpass Butterwoth filter, 8-biquads parametric EQ, fader adjustment, noise gate, compressor and automix.
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.
A matrix within the audio mixer, provides the capability to route each input signal to specific outputs and adjust their node levels as needed.
Each of the 4 outputs are equipped with 8-biquads parametric and a 31 Band graphic-equalizer, level adjustment, automatic antifeedback with 5 dynamic/fixed notch filters, noise gate, compressor and limiter.
Antifeedback system is responsive and adapts dynamically using notch filters to attenuate feedback frequencies.
By using the PC-Software all function adjustments of the parameters can be made as well as creating and storing the 20 presets via USB connection.
Remote control by RS 232-interface.
The digital mixer is also available as Andante 16 version with 16 microphone/line inputs and 8 outputs.
