The HD-R1 is a two-channel, single rack-mount recording and playback device created with the sound contractor in mind. Utilizing the highly reliable CompactFlash card, the HD-R1 records PCM files at up to 96 kHz or MP3 files at 44.1/48 kHz both with 16/24-bit resolution. File transfer can be accomplished via Ethernet, USB, or a card reader. The ability to control the unit remotely is provided via RS-232, Parallel, and RJ45 100-Mbit Ethernet.
To further enhance the HD-R1’s feature set, mic preamps with 20-dB PAD and phantom power (rear-panel selectable) have been included. A variety of contractor-friendly I/O options, such as unbalanced RCA, balanced XLR and Euroblock, and SPDIF digital (coaxial and optical) are also available.
And of course … the HD-R1 offers traditional source device features like power-on play, front panel rotary input level controls, a headphone jack with level control, and a variety of playback modes.
