About the Alesis HD24 24-Track 48kHz Hard Disk Recorder
The Alesis HD24 24-Track 48kHz Hard Disk Recorder is a 24-track hard disk recorder designed to mirror the workflow of tape-based analogue recording. It features 24 TRS balanced inputs and outputs with 24-bit converters supporting 44.1 kHz and 48 kHz sample rates. Three sets of ADAT litepipe inputs and outputs are included, alongside word-clock input, punch-switch input, 9-pin in/out and a mini-remote input. The unit supports 88.2/96 kHz operation, at which point it operates as a 12-track recorder. Up to five HD24 units can be stacked together, and the recorder achieves sample-accurate sync with ADAT devices, including compatibility with the BRC. Storage uses IDE hard drives, making media costs low per track minute.
Alesis HD24 24-Track 48kHz Hard Disk Recorder — buyer FAQs
What is the Alesis HD24 and how does it record audio?
The Alesis HD24 is a 24-track hard disk recorder that stores audio on IDE hard drives and is designed to operate much like a tape-based analogue recorder in terms of workflow. It records at 24-bit resolution with sample rates of 44.1 kHz or 48 kHz across all 24 tracks. At 88.2 or 96 kHz, the unit functions as a 12-track recorder, and 96k support requires an external converter or the Alesis upgrade option.
What connections does the HD24 offer for integrating with other studio equipment?
The HD24 carries 24 TRS balanced inputs and outputs, three sets of ADAT litepipe inputs and outputs, word-clock input, punch-switch input, 9-pin in/out and a mini-remote input. It achieves sample-accurate sync with ADAT devices and remains compatible with the BRC. Up to five HD24 units can be stacked, extending total track count for larger sessions.
Who makes the HD24, and where does it sit in the Alesis recording product range?
The HD24 is made by Alesis. It sits within Alesis's hard disk recorder line and carries forward the ADAT litepipe connectivity central to the company's earlier tape-based ADAT technology, maintaining compatibility with that ecosystem including sample-accurate sync and BRC support. The longevity of that ADAT infrastructure is a notable aspect of the platform's design.
Why are IDE hard drives a practical storage choice for the HD24?
IDE hard drives offer a low cost per track minute compared to other recorder media formats, which makes running and expanding the HD24 relatively affordable over time. Media expenses stay modest whether the unit is used for long sessions or high track counts, and up to five HD24s can be stacked to increase capacity further.
What should I check when buying a used HD24?
Check that all 24 TRS inputs and outputs are functioning, that the ADAT litepipe connections respond correctly, and that the installed IDE hard drive is detected and recording reliably. Confirm whether a mini-remote is included, and if 88.2/96 kHz operation is needed, clarify whether the converter upgrade is fitted.
