Hot on the heels of Digidesign with the Native recording system 25/11/02
MOTU's expansion of the PCI-424 system is moving on a pace with the introduction of the new high-end samplerate HD192, a two rack-space 12-channel high definition audio interface for Macintosh and Windows personal computers. The HD192 provides
high-quality audio recording and playback on 12 XLR analog inputs and
outputs at any standard sample rate up to 192 kHz. A fully expanded HD192
system provides up to 48 channels of simultaneous analog I/O. As with MOTU's
other new PCI-424 systems (the 24I/O and 2408mk3), the HD192 will be sold as
both a core system (with PCI card and AudioDesk software for $1,895) and
expansion I/O ($1,595).
"The MOTU HD192 is the first full-featured, expandable high definition audio
interface for the native recording studio," said Jim Cooper, Director of
Marketing at MOTU. "The HD192 is meant for those who demand the very best
12 channels at 192 kHz
All 12 XLR inputs and outputs on the HD192 rear panel support operation at
44.1, 48, 88.2, 96, 176.4 and 192 kHz. Latest-generation converters and
state-of-the art design provide exceptional audio quality. The measured
dynamic range for the 12 analog inputs is just over 120 dB (A-weighted at 48
kHz) with a measured THD+N of 0.0005% (-106 dB).
AES/EBU digital I/O is also provided at samples rates up to 96 kHz with
independent real-time sample rate conversion on the digital input and
output. A separate "AES word in" BNC connector allows users to clock the
AES/EBU section independently from the rest of the system. System word clock
input/output is also provided on BNC connectors.
Up to 48 IO
An HD192 core system includes the PCI-424, the same enhanced PCI card
introduced earlier this year with MOTU's 2408mk3 system. The PCI-424 card
adds a fourth Audio Wire port that allows users to connect up to four MOTU
audio interfaces to the computer. At 12 channels each, a fully expanded
HD192 system provides 48 simultaneously active analog inputs and outputs.
The HD192's PCI424 card features CueMix DSP�, a flexible DSP-driven mixing
and monitoring matrix that provides the same near-zero monitoring latency as
today¹s latest digital mixers. CueMix DSP� allows HD192 users to monitor
live inputs with no audible delay and no processor drain on the host
computer¹s CPU. The CueMix DSP engine resides on the PCI424 card, so it
works across all interfaces connected to the card. The included CueMix
Console software provides an on-screen mixer that gives users hands-on
control of their monitor mix, regardless of what audio software they prefer
to use. CueMix Console provides a separate stereo bus for every pair of
outputs, giving users up to 24 separate busses on a fully expanded HD192
system and more with other MOTU expansion interfaces. Digital Performer
users, as well as users of ASIO2 host applications, have the additional
option of controlling CueMix DSP directly within the host application¹s
mixing environment. CueMix DSP completely eliminates the buffer latency
associated with monitoring live inputs in host-based recording systems.
On-board SMPTE sync
Like the 2408mk3, the HD192 provides on-board SMPTE time code
synchronization features. These features allow users to slave their HD192
system to SMPTE time code (via any analog input) without a dedicated
synchronizer. The PCI424 card provides a DSP-driven phase-lock engine with
sophisticated filtering that provides fast lockup times and sub-frame
The included software also provides a complete set of tools to generate
SMPTE for striping, regenerating or slaving other devices to the computer.
Like CueMix DSP, the synchronization features are cross-platform and
compatible with all audio sequencer software.
The MOTU HD192 is expected to ship in the first quarter of 2003.
