Alesis HD24 Product Details
THE ONLY HARD DISK RECORDER WORTHY OF THE ADAT NAME
HD24 is the world's first 24-track hard disk recorder designed to fit into any ADAT environment and match ADAT's legendary performance and affordability.
HD24 is built exclusively for the purpose of recording music instead of data, resulting in remarkable stability and performance. HD24 enables engineers to record up to 24 tracks of high-resolution 24-bit recording at 44.1 and 48 kHz sample rates.
Two hot-swappable media bays provide convenient access to recording drives and allow data backup in minutes. You can edit tracks internally or easily transfer to computer via an Ethernet connection.
HD24 features ADAT Optical and ADAT Sync, enabling it to work efficiently with existing systems. It offers the same exceptional user-friendly interface ADAT users have come to expect.
HD24 can be upgraded to HR24XR with the EC2 module. This user-installable option replaces the A/D and D/A converters with the renowned AKM converters used in the acclaimed MasterLink. EC2 improves performance at all sample rates and also expands analog and digital-input compatibility to include 88.2 and 96 kHz sample resolutions.
HR24 packs 24 channels of digital audio I/O into a single-unit recorder that easily fits into any environment.
Alesis reinvents digital recording. Again.
