Audison AFM511B 1200W 5-Channel D-Class Fully Bridgeable DSP Amplifier (AF M5.11 BIT)

Allows You to Maximize the Acoustic Performances of Your Car Audio System!

5-Channel DSP Amplifier (AF M5.11 BIT)
The AF M5.11 bit is an amplifier with integrated DSP, equipped with 4 high-power amplified channels settable in bridge mode, a dedicated SUB channel for even more power, and 6 pre-amplified outputs, to reach a total of 11 output channels. It features 8 analog inputs of PRE IN type (Lo-Level), 8 analog inputs of SPEAKER IN type (Hi-Level), and 1 S/PDIF digital optical input.

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 you to maximize the acoustic performances of your Car Audio system.

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

The AF M5.11 bit is compatible with the remote controller DRC AC, which allows control of 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.
