In the studio or on the road, the Alesis ADAT-HD24 Digital Recorder gets the job done. This 24-track, 24-bit/96kHz hard disk recorder was originally designed to fit comfortably into any standard ADAT environment and match ADAT's legendary performance and affordability. Today, more an more pros are using the HD24 for high-quality audio capture, while freeing up computer resources for more processor-intensive plug-ins, virtual instruments, and mixing.

The onboard 40GB hard drive can be easily extended with low-cost IDE computer drives that are as affordable as traditional ADAT tape on a per-track basis. 2 hot-swappable media bays provide convenient access to the recording drives and allow quick backup from one hard drive to another. The only HD recorder that includes ADAT optical format and ADAT Sync to work efficiently with existing ADAT systems. 44.1kHz and 48kHz internal sample rates, slaved to external word clock, with 96kHz and 88.2kHz option. 12 tracks at 88.2 or 96kHz through the digital ins. 24 tracks at 44.1 or 48kHz through the digital or analog ins. 103dB A/D/A converters. Internal editing including cut, copy, paste, and track-move with undo. Multiple units can be synchronized to create a larger system. 24 analog ins and outs, ADAT Optical in/out, word clock in. All necessary hardware and connectors included.
