Robust For The Road - Elegant For The Studio!

Start with 24 tracks of 24-bit audio, straight-up compatibility with the over 150,000 ADATs already in operation worldwide, superbly robust IDE hard drives for storage (that are removable, no less), and finish it off with 24 channels of 24-bit analog I/O and 24 channels of ADAT optical digital I/O as standard. THAT's the HD24!

The HD24 provides 24 tracks of high-resolution 24-bit recording at standard sample rates of 44.1kHz, 48 kHz, or at 88.2kHz (96kHz with a forthcoming 96 kHz I/O option). External word clock input is provided for slaving to external clock sources. You want the ability to cut, copy, paste, insert and move tracks and segments of audio with an undo function? These functions can be controlled from the HD24 front panel, or optional remote control.

Recognizing that a broad range of affordable computer-based editing solutions are already in the market, Alesis provides multiple ways to export audio for additional processing and graphic editing. A rear panel Ethernet connection makes HD24 files accessible to computers in industry-standard AIFF format.

Additionally, the HD24's 24-bit ADAT optical I/O allow simultaneous transfer of 24-track material in real time to computer audio cards and other products using ADAT optical format. The ADAT HD24 can be controlled via supplied LRC remote control, and MIDI machine control. Control of transport, track arming and editing functions will be possible via an optional full-function remote control. HD24 supports MIDI commands and sys-ex bulk dumps via MIDI In/Out connectors.

Expand Your Tape-Based System!
The HD24 can be used to expand and update any tape-based ADAT/BRC system. Using the Alesis Sync In/Sync Out connectors, the HD24 appears as three 8-channel ADATs in your chain. Once a chain of machines are established, the HD24 will behave as extremely fast tape-based ADATs.

  • 24-Track, 24-Bit, digital audio recording
  • 44.1kHz & 48kHz internal sample rates

Sweetwater Advice

Carson McClain
If you need a rock solid, easy-to-use recording solution the HD24 will not let you down. Perfect for live, studio, or performance the HD24 is my choice for the customers who have the most demanding needs. The FireWire card is a must if you will be using this with a computer.

Very Nice Multi Track

I have been in the recording field for aprox. 30 yrs. Started out 4 track and worked my way up the ranks to 8 then 16 but this is the bomb. 24 tracks of digital recording that is VERY stable. So easy ... read more [+]to use ( Even a cave man could use this machine). Have done many large projects with it and no problems yet. So fast and easy to use. TRS ins and outs make it a breeze to connect signals. Mix down is much more accurate than with other machines. What you hear is pretty much what you get, providing you have good refrence monitors. LOVE IT ! close [-]

I have used the HD-24 for 9 years and have recorded over 100 songs with it.I have never had a single problem with it in 9 years.

It is very easy to use and has great editing capabilities. It also has great sounds.If anything ever happens to it, and Alesis stops making it, I'm out of the recording business. close [-]

ADAT HD24

by Anonymous
February 1, 2005
Music Background:
Recently had a chance to try out the HD24. After receiving the unit for use in a remote truck that had ADAT xt20's, we found it was not really plug and play in an ADAT environment. There are no... read more [+] elco connectors which meant either cutting off the existing connectors and wiring 48 1/4 inch plugs or using the a-d converters in the xt 20's and going into the machine's lightpipes. We elected to use the lightpipes. We also could not synchronize to smpte from the video truck. The video truck had just received the unit and was unaware of this. The manual does spell this out and states that it can chase smpte using the BRC. It also states several other things the BRC can't control on the HD 24. Since we were on location (without the BRC manual) we called Alesis for help setting the BRC up to feed smpte to the HD 24. Had to leave a message. Got no response. Job over. Loaded out and still don't know if the machine will lock to external smpte timecode. Other than that, it seemed simple to operate. I was disappointed that there were no elco connectors to install the machine in my existing "ADAT environment" and no way to obtain factory help when I needed it. close [-]
