HDA digital 6-way headphone amplifier

A cost-effective digital headphone amplifier for all your headphone monitoring duties

The CEDAR HDA headphone amplifier is a 24-bit, 96kHz rackmount unit that receives an AES/EBU or SPDIF input and converts it to six individually buffered 1/4" (6.3mm) stereo headphone outputs, each with its own volume control.

Suitable for use in almost all digital environments and designed to complement CEDAR's award-winning DNS series (as well as being an integral element in the CEDAR CSS-1500 and CSS-3000 Surveillance Systems) the HDA is also perfect for use with CEDAR Cambridge and our Duo rackmounts, connecting directly to their AES/EBU (XLR) or SPDIF (phono) outputs to provide the highest quality audio directly to the headphones. It handles all standard sampling frequencies up to and including 96kHz, will decode 50/15µs emphasis, and has a dynamic range in excess of 100dB. It delivers up to 150mW per headphone output with a maximum output level of +12dBu.
