CEDAR ADA and HDA converters


To ensure that your audio restoration products are useful in all environments - analogue and digital - we supply two high quality 24/96 converters in rackmount format.

ADA: A cost-effective converter for almost all stereo A/D and D/A duties

This stereo, 24-bit, 96kHz 1U rackmount unit that produces an AES/EBU or SPDIF output from a balanced or unbalanced analogue stereo input, and a stereo balanced or unbalanced output from an incoming AES/EBU or SPDIF input. Designed to complement CEDAR's award-winning DNS-series and Duo-series hardware modules as well as CEDAR Cambridge, the ADA offers four sync modes, professional and consumer formats, emphasis on/off, user-selectable input levels of up to 27dBu, and a maximum output level of +24dBu.

With both professional (XLR) and consumer (phono) analogue inputs and outputs, the ADA is usable in almost all analogue and digital environments. With a dynamic range of greater than 110dB and a signal to noise ratio of better than 109dBfs, it's suitable for all but the very most demanding converter tasks.

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.
