Notes

HD24 was the world's first 24-track hard disk recorder designed to fit into any ADAT environment and was built exclusively for the purpose of recording music instead of data.

HD24 packs 24 channels of digital audio I/O into a single-unit recorder that easily fits into any environment and enables engineers to record up to 24 tracks of high-resolution 24-bit recording at 44.1 and 48 kHz sample rates. 

HD24 has two hot-swappable media bays provide convenient access to recording hard disk drives and allow data backup in minutes.

Digital audio tracks can be edited internally or easily transferred to computer via an Ethernet connection. 

HD24 features ADAT Optical and ADAT Sync, enabling it to work efficiently with existing systems.

There is an option module EC2 (user-installable) that upgrades HD24 to HR24XR. This option replaces the A/D and D/A converters with AKM high resolution audio converters. This module improves performance at all sample rates and expands analog and digital-input compatibility to include 88.2 and 96 kHz sample resolutions.
