Benchmark DAC3 HGC Converter Black

Internal digital processing and conversion is 32-bits, and this processing includes 3.5 dB of headroom above 0 dBFS. This headroom prevents the DSP overloads that commonly occur in other D/A converters.

Four balanced 32-bit D/A converters are summed together to create each balanced analogue output. This 4:1 summation provides a 6 dB noise reduction, and gives the DAC3 industry-leading performance.

Any practical audio system will need a volume control. These days, most audio devices use digital volume controls. These controls place significant demands on the quality of a D/A conversion. An internal D/A converter that starts with the equivalent of 14-bit performance, may only deliver 12-bit performance at typical volume-control settings.

In contrast, the Benchmark DAC3 D/A converter uses a motor-driven 32-bit digital volume control driving a 32-bit D/A conversion stage. This combination delivers true high-resolution audio performance over a wide range of volume settings.
