MOTU HD192 (PCI 424) - 12 Input / 12 Output High Resolution Hard Disc Recording System with PCI 424 Card for Mac and PC

The HD192 hard disc recording system from MOTU provides an interface with twelve, high-quality, 24-bit/192kHz analog inputs and outputs. The interface is designed with the latest generation 24-bit, enhanced multi-bit, 128x oversampling 192kHz converters, which deliver a remarkable A-weighted signal-to-noise ratio of 120dB. In addition to the interface the system includes a PCI-424 card and Audiodesk workstation software.

Audio activity for every input and output is represented on the front panel by dedicated nineteen-segment LED bar graph. The twelve analog inputs and outputs are on XLR connectors operating at +4dB. AES/EBU digital input and output is also provided with the added ability of delivering sample rate conversion both on input and output. Two "over" meters are included - a temporary over meter and an over/hold meter that is re-settable via software. Comprehensive clock status LEDs are also included that show at a glance the current sampling rate and clock source. Wordclock sync is provided on BNC connectors.

The HD192 uses the second generation AudioWire protocol, a high-bandwidth digital audio format capable of carrying up to twenty-four channels of 96kHz or twelve channels of 192kHz digital audio in and out of the computer at the same time. The included PCI-424 card features a powerful DSP chip dedicated to creating a custom tailored monitor mix of up to ninety-six channels of audio. Because the mixing takes place on the card itself, the system provides near-zero latency performance. Up to four audio interfaces (which are hot swappable) can be connected to a PCI-424 in any combination.
