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.
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 2408
MK3. 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.
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 exter-
nal 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.
