Audison Forza 1120W 8-Channel D-Class Amplifier
with 14 CH DSP AF M8.14 BIT
- 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 82% 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 14 output channels (8 amplified, 2 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
