I can't make heads or tails of your description because it's so steeped in marketing language nonsense.
How does the device attenuate output from a digital input (other than the XLR attenuators)? Is it strictly digital volume control? A combination of digital and analog? If analog, how does it work? Resistors? Stepped attenuation? Relays?
Does anyone have a plain sense answer or am I missing something? Is it really just a pot?
HGC™ Hybrid Gain Control HGC™ is Benchmark’s unique hybrid gain control that combines analog and digital gain control into a single volume control knob. The HGC™ system uses an active analog gain control for analog inputs and a 32-bit dithered volume control for digital inputs. Both types of inputs leverage the low-impedance passive Manual for DAC3 HGC and DAC3 L with 2.X Firmware - Rev. D Page 7 analog attenuation system at the XLR outputs. The dual-domain HGC™ system combines the high dynamic range of Benchmark’s HDR™ analog control (used in the DAC1 HDR) with the low distortion and accuracy of a digital control. HGC™ outperforms traditional analog or digital volume controls, including the twostage DAC1 HDR™ system. Musical details are preserved over a very wide range of output levels. Analog inputs are controlled in the analog domain. Digital inputs are controlled in both domains. The volume control is a servo-driven analog potentiometer. This control rotates in response to commands from the remote control while providing the convenience of manual adjustments with a physical knob.
