Alesis HD24 Hard Disk Recorder

Monday, March 30, 2009

The Alesis HD24 hard disk recorder is designed to fit comfortably into any standard ADAT environment and match ADATs legendary performance and affordability.

The HD 24 is the first hard disk recorder built from the ground up exclusively for the purpose of recording music instead of data resulting in remarkable stability and performance. The HD24 uses standard, low-cost IDE computer drives, making the cost of recording media no more than traditional ADAT tape on a per track basis.

Alesis incorporate two hot-swappable media bays in the HD24 to provide convenient access to the recording drives allowing speedy data backup. The HD 24 allows you to edit tracks internally or easily transfer to computer via built-in Ethernet. The Alesis are the only Hard Disk Rrecorders on the market with standard ADAT Optical and ADAT Sync, enabling them to work efficiently with existing systems.
