Audison AFM511B 5-Channel Amplifier DSP

Through accessory modules it is possible to increase the number of inputs: F4IN - adds 4 analog SPEAKER IN input channels; F2O - adds 2 digital inputs: digital optical S/PDIF or digital coaxial S/PDIF, selectable by a dedicated switch on the module.

Equipped with a high-performance 32-bit digital signal processor (DSP) clocked at 147 MHz and 24 -bit AD and DA converters, it allows to maximize the acoustic performances of your Car Audio system.

Each output channel features: adjustable Graphic / Parametric equalizer with 15 poles; electronic crossover adjustable in 1 Hz steps, with Butterworth / Linkwitz / Bessel / Chebyshev / QLP filters and slopes from 6 to 48 dB; digital control of time delays.

Each input channel features: adjustable Parametric equalizer with 12 poles; digital control of time delays.

The AF M5.11 bit is compatible with the remote controller DRC AC, which allows to controls the main system functions (Master volume, Sub volume, source change, memory change, enable/disable Final tuning EQ) without using a PC.

The AF M5.11 bit can be interfaced to any standard system, even on cars equipped with an integrated audio processor, thanks to the automatic de-equalization feature that analyses and provides a flat signal from the car audio source.

The native Maestro port ensures the interfacing with devices equipped with the Maestro / ADC protocol, which makes this product unique in its category and ready to install also in those vehicles with the most advanced infotainment systems.
