DACS Clarity HeadMaster D-A Converter and Monitor Controller
A reference monitor controller for critical listening; the Clarity
HeadMaster is a D-A converter, monitor controller and headphone
amplifier. D-A conversion from Crookwood coupled with DACS’ renowned
clarity and detail in the analogue domain, creates a uniquely
impressive, multi-purpose device.
Ideal for recording, mastering and mixing engineers and producers,
the Headmaster has been designed for critical listening from a variety
of analogue and digital sources.

Technical Specifications
The unit has four inputs: AES/EBU,
SP/DIF, balanced analogue and unbalanced analogue. The analogue inputs
use THAT InGenius® balanced input ICs providing 90dB CMRR, DC coupling
and THD+N figures of around 0.0015% input to output. Inputs are selected
using the stainless steel front panel switches with LED indicators.
HeadMaster’s outputs include two headphone outputs (one on the front
panel, and one on the rear) and two selectable monitor outputs. The
headphone and monitor outputs have independent volume control and are
fitted with conductive plastic pots.
The rear panel features a fixed level balanced analogue output from
the D-A input, with digital FSD set to provide and output of +18dBu. The
headphone output uses DACS’ renowned Clarity headphone driver circuit.
The balanced outputs are DACS’ high performance driver circuits.
The Crookwood D-A uses a technique that makes it impervious to jitter
on the incoming signal, and provides unobtrusive anti-aliasing
filtering. The result is a clean accurate audio output, unaffected by
jitter, or other digital anomalies. It simply does not get any better
than this.
