Audison Voce AV 5.1k HD - 5-Channel Amplifier with Hi-Res DAC and Full DA HD
The Audison Voce AV 5.1k HD is a 5-channel amplifier for demanding car hi-fi setups, exclusively using digital inputs, making it ideal for integration with a DSP with digital output. Two Class A channels, two Class AB channels, and a powerful Class D sub channel deliver up to 1650 W RMS in total. With Hi-Res audio certification, an integrated 192 kHz/24 bit D/A converter, and AD-Link for the bit One HD Virtuoso, a continuously digital Full DA HD chain can be realized.
