Take Your ISA 428 Into the Digital Realm!
The MH-442 is a convenient digital expansion card for the Focusrite ISA 428 "Pre Pack" studio preamp. The MH-442 features up to 24-bit/192kHz conversion, signal-to-noise ratio of 120dB and Word Clock I/O for synchronization with your digital studio gear. It can be easily retrofitted to your existing ISA 428 with no soldering or complicated installation procedures.

Focusrite MH-442 Digital Expansion Card at a Glance:
  • Installs easily on existing ISA 428 units
  • Offers 16, 20 or 24-bit conversion at sample rates of 44.1, 48, 88.2, 96, 176.4 or 192kHz
  • Standard or 256x "Super Clock" Word Clock options
  • AES/EBU, S/PDIF and ADAT optical outputs

Installs easily on existing ISA 428 units
It's easy to retrofit your existing ISA 428 with the MH-442 Digital Expansion Card. No soldering or complicated installation procedures are required. Simply undo a few screws, hook up one clip connector to join to the main PCB and you're in business. Your ISA 428, a landmark among analog preamps, is now the ideal front end for virtually any digital recording system!

16, 20 or 24-bit conversion at sample rates of 44.1, 48, 88.2, 96, 176.4 or 192kHz
Even if you're only recording at 16-bit/44.1kHz resolution, the MH-442 can handle it. It features adaptive dithering and supports most sample rates - 44.1, 48, 88.2, 96, 176.4 or 192kHz. So from CD quality to high definition, you'll be sure to get the best possible A/D conversion. And with a signal-to-noise ration of 120dB (A-weighted), the MH-442 delivers one of the widest dynamic ranges available from any digital converter.

Standard or 256x "Super Clock" Word Clock options
When using multiple pieces of digital equipment it is necessary to make sure that their bitstreams are all in sync. The MH-442 features Word Clock I/O via standard BNC connectors. Plus, it supports both standard Word Clock and the Digidesign-specified 256x "Super Clock" for sync compatibility with Pro Tools hardware.

AES/EBU, S/PDIF and ADAT optical outputs
The MH-442's digital audio outputs include AES/EBU (both single and dual wire specs), S/PDIF and ADAT formats (ADAT is maximum 96kHz via 2 ports) with sample rates selectable between 44.1, 48, 88.2, 96, 176.4 and 192kHz, 16, 20, and 24 bits with adaptive dithering. Connections are via 2 x 9-pin D-type connectors (optional, see here for an AES adapter and here for a S/PDIF cable) and standard ADAT optical connections. Word Clock is via BNC in and out.


Focusrite MH-442 Digital Expansion Card Features:
  • AES/EBU and S/PDIF outputs via dual 9 pin D-type connectors
  • ADAT optical output
  • Bit depths 16, 20 or 24 bit
  • Frequency options 44.1, 48, 88.2, 96, 176.4 and 192kHz
  • Clock options Standard or 256x
  • Meter: 0dBfs = +22dBu
  • SNR - 120dB A-weighted

Turn your ISA 428 into a digital front end!

 ISA 428 with the DIGITAL OPTION  
by Drew from Seattle, WA, September 18, 2007
Music Background:  audio post and music production


“I own an 02. The digital option was expensive since I'm only using the ADAT output currently. The best thing this box has going for it is the additional 4 balanced line inputs aside from the 4 fully loaded preamps that are included. Somehow I didn't understand that until I purchased. It's such a pain to manually set the clock for sessions in Pro Tools. I'd almost rather use the 02 and save...” Read More
