Features and functionality

  • The Alesis HD24's FTP function is notably slow, transferring at 480KB/s, far less than the advertised 10Mbit/sec, making direct transfers cumbersome.

    Source

Setup and maintenance

  • Using a crossover cable directly to a computer can improve FTP speeds, bypassing network issues often found with newer network cards.

    Source

Software and compatibility

  • The HD24 can only recognize up to 32GB drives due to BIOS limitations unless an upgrade is applied, which may limit available storage options.

    Source

Comparisons

  • Owners often compare the HD24 to its competitors like the Mackie HDR2496 and Tascam HDR, noting its role as a non-linear tape machine replacement.

    Source

  • The HD24 is recommended for analog studios wanting to maintain a traditional workflow but with digital convenience, using either digital or analog mixers for monitoring.

    Source
  • With SSD upgrades, the HD24 offers approximately 80 hours of 24-track recording, ideal for extended live recording scenarios.

    Source
  • The device has been used effectively for live gig recordings by connecting to FOH console direct outs or via mic splitting.

    Source

Mods and upgrades

  • The Noctua NF-R8 Redux 1200 fan can replace the original for a quieter operation, requiring snipping and splicing of the positive and earth wires.

    Source
  • Use Startech IDE2SAT2 converters to transition from IDE to SATA, allowing the use of Kingston SA400 480GB SSD drives.

    Source

User experience

  • Owners have reported the HD24 as reliable for live recording, despite noting it can be clunky for playback where seamless song transitions are required.

    Source

Other

Fantastic hard disk recorder!

This is a 24 channel 24 bit 96kh hard disk recorder by non other than Alesis! This recorder will give you up to 24 track of digital quality recordings. It comes with two hard drives that can be switched out and has two drive bays. Its menu is very easy to navigate. It sounds really good!

From an interview with the Prodigy's chief live sound engineer: "Everything is recorded to an Alesis HD24 hard?disk multitracker, to be mixed in Logic in the two or three days of down time that Burton and the band enjoy between weekend festival slots. "I'll spend a lot of time cleaning up the track and getting rid of spill. I'll go through and clean up all the vocals, not changing anything, but I'll hand?draw automation to take all the background noise out and get them as clean as possible. Same with some of the snare hits and stuff like that.”

For the session, recorded in a 15th-century manor house in Brentford, a BBC truck was used as a mobile control room and contained a Calrec desk and Studer tape machine, although the latter required so much power that the recording was eventually made using Martin's own Alesis HD24.
