High-Definition
192kHz Audio Interface
for Mac and PC
Designed for those who demand the very best audio
quality available, the HD192 is equipped with the latest
generation 24-bit, enhanced multi-bit 128x oversampling
192kHz converters to achieve a remarkable A-weighted
signal-to-noise ratio of 120 dB with balanced XLR
connectors throughout. Ideal for surround applications,
the HD192’s 12 inputs and 12 outputs can support two
simultaneous 5.1 mixes. And the HD192 is full of
advanced features, like AES/EBU I/O with sample rate
conversion both in and out. The PCI-424 card introduced
with the 2408mk3 is 192-kHz ready. Just connect the HD192
expansion interface to record 192-kHz audio. The HD192 can be purchased
as an expander for an existing PCI-424-based MOTU Audio System, or as a core system which includes the PCI-424 card
and Audiodesk workstation software.
Highest-Quality
A/D Converters
◆ The most important link in the digital
recording chain is the A/D converter. It is
the critical component that converts your
analog input signal into digital information.
The higher the quality of the A/D converter,
the better your recordings will sound. The
192kHz converters in the HD192 are the
same ones used in more expensive HD
systems.With 120dB A-weighted dynamic
range and a THD+N of 0.0005%, the HD192
is simply the best sounding front end you
can buy for your digital audio workstation.
Comprehensive Metering
◆ The HD192’s front panel provides dedicated
19-segment level meters for all 12 inputs
and outputs. Two over meters are included,
a temporary over meter and an over/hold
meter that is resettable via software.
Comprehensive clock status LEDs are also
included so you can see at a glance the
current sampling rate and clock source.
Front Panel Power Switch
◆ Useful in the unlikely event you wish to turn
off your HD192. An interesting fact about
MOTU Audio interfaces is that they are hot
swappable. This means you can power off,
plug-in, add and remove interfaces without
turning your computer off or restarting.
Inputs/Outputs
◆ 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 and use professional-
grade XLR connectors operating at +4 dB.
AES/EBU
◆ The HD192 features stereo AES/EBU digital
I/O with built in sample rate conversion. This
gives you the ability to integrate external
digital audio sources, no matter what the
sample rate, while recording audio at higher
sample rates on the analog I/O of the
HD192. For example, you can still take
advantage of the 96-kHz digital I/O on your
favorite outboard reverb, while recording
audio at 192-kHz.
Word Clock I/O
◆ An industry-standard word clock input and
output allow the HD192 to synchronize
smoothly with today’s digital audio studio.
The word clock output can be used as a
master clock to drive other digital devices in
your studio, such as a digital mixer. The AES
digital I/O can be driven separately via a
dedicated word clock input. You can even
slave to a 48kHz clock source, even when
the HD192 is operating at 192-kHz.
Audio Wire
◆ The HD192 uses the same second generation
Audio Wire as the 2408MK3. It is a high-
bandwidth digital audio format capable of
carrying up to 24 channels of 96-kHz or 12
channels of 192-kHz digital audio in and out
of the computer at the same time.
Power Supply
◆ Like all MOTU hardware products, the
HD192 comes with an internal power supply
and standard detachable IEC power cable.
No wall warts or line lumps.
