Audison 4-Channel Class D DSP Amplifier - AF C4.10 bit
AF C4.10 bit
AF C4.10 bit boasts four high-fidelity amplified channels 90W x 4 @4Ω*, 150W x 4 @2Ω*, with the audiophile sound of the latest generation Audison D-Class technology. Higher switching frequencies, steeper filtering, and higher-tolerance components deliver sound above and beyond the expectation of Class D – in an amazingly compact package! This is combined with native DSP working at 24 bit/96 kHz, extending the audio band up to 40 kHz and earning the coveted High-Resolution certification. Bridging channel pairs results in 300 x 2 @4Ω, guaranteeing flexible and powerful performance. Support for the Audison B-Con’s Absolute Volume function guarantees maximum bit depth, even with wireless connections!*Output Continuous Power (RMS) @14.4 VDC, 1% THD, all channels driven.
FEATURES
- Improved audio performance and power thanks to the latest generation of ADT (Audison D-Class) technology
- Unbeatable power/volume ratio up to 0.68 W RMS/cm³ reaching 81% of efficiency
- Next-generation bit Drive software platform
- Hi-Res compatibility performance, with an extended audio band up to 40 kHz, made possible by and DSP working operation at 24 bit/96 kHz
- Maximum versatility thanks to the possibility of using the bridging option for each pair of power outputs
- Up to 10 output channels (4 amplified, 6 native pre-out outputs, 4 optional pre-outs) controlled by the DSP to expand the system with other amplifiers
- 8 high/low-level inputs (and an optical Toslink digital input) support total connectivity even with the most complex OEM systems
- Extension card slot (additional 4 analog or 1 digital inputs)
- Electrical signal analysis for each input channel ensures proper integration and correction
- Acoustic analysis (with your USB microphone) integrates the response graph into the equalizer display. This ensures efficient tuning and great sound!
- Advanced signal routing options allow the technician to go beyond the predefined system definitions in the Configuration Wizard
