Description
AF companion amplifiers are designed to add powerful amplification channels to AF bit processor amplifiers. A plug-and-play signal input harness is included for easy connection to AF bit amplifiers. AF companion amplifiers are also perfect for use with systems controlled and managed by a standalone bit processor, such as a bit One HD Virtuoso.
- "Wired" architecture without analog preamplifier functions such as crossover filtering
- Intended for use with external processors for full signal control
- Four high-fidelity amplified channels: 160W x 4 @ 4Ω, 260W x 4 @ 2Ω
- Audiophile sound thanks to the latest generation of Audison D-Class technology
- Higher switching frequencies for better sound quality
- Tighter filtering and higher tolerance components
- Sound that exceeds D-class expectations in an incredibly compact enclosure
- Extended audio bandwidth up to 42 kHz allowing High-Resolution certification
- Bridging channel pairs to achieve 520 W x 2 @ 4Ω
- Flexible and powerful performance suitable for any setup
- Exceptional signal-to-noise ratio of 103 dBA for pristine audio quality
- Ultra-low distortion of 0.05% for faithful sound reproduction
- 83% efficiency for optimized consumption and less heat dissipation
- ±12 dB remote volume control for precise adjustments
