HDA: INTRODUCTION

The CEDAR HDA headphone amplier is a 24-bit, 96kHz rackmount unit that

receives an AES/EBU or SPDIF digital input signal and converts it to six individually

buffered ¼” (6.3mm) stereo headphone outputs, each with its own volume control.

Input and Output

The input connectors comprise a balanced XLR-3 for the AES/EBU input and

an unbalanced phono connector for the S/PDIF input. A button located on the

rear panel determines which input is active, and de-emphasis on the output can

be controlled via a dipswitch. If de-emphasis is selected, the HDA will decode

50/15µs emphasis when indicated by the status bits in the incoming digital audio.
