Focusrite MH-442 ADC Expansion Card for ISA 428

What we think:


The MH-442 coupled with the Focusrite ISA 428 is a great way to get into some serious pro channels of mic pres and AD converters. The MH-442 ISA 428 ADC expansion card features 8 channels of high-end AD converters. Installed in the ISA 428, channels 1-4 of MH-442 are hardwired to channels 1-4 on the ISA 428. The remaining channels 5-8 on the MH-442 can be used with any 4 channels of other mic preamps. We've been testing out a lot of higher end mic pres and AD converters and the Focusrite ISA 428 really shines. Very musical preamps. The pre and AD combo is killer.

Manufacturer Description:


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. 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. 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 and standard ADAT optical connections. Word Clock is via BNC in and out. 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.
