AES word clock in
A BNC Word clock input connector is provided for
independently synchronizing the AES/EBU output of the
HD192 to a standard input clock.
Level Meters
The front panel of the HD192 I/O displays several banks of
status LEDs.
On the right are two banks of meters for the twelve analog
inputs and twelve analog outputs. For each channel, there is a
19-segment meter that measures from -42 dB to 0 dB, along
with two red ‘over’ lights. The top LED remains illuminated
after clipping occurs until it is cleared via software (either
manually or via a configurable time-out period). The red
LED below it only lights momentarily when clipping.
The
Clock
section on the left displays the current system
clock setting (44.1, 48, 88.2, 96, 176.4, 192 or
no clock
), as
well as the AES/EBU clock setting if sample rate conversion is
taking place independently of the system clock.
16-BIT AND 24-BIT RECORDING
The PCIe-424 system handles all data with a 24-bit signal
path, regardless of the I/O format. Using AudioDesk™, the
PCIe-424 system’s Macintosh workstation software
(included), you can record and play back 16-bit or 24-bit
audio files at 44.1, 48, 88.2 or 96 kHz via any of the system’s
analog or digital inputs and outputs. The HD192 also offers
recording at 176.4 or 192 kHz. On Windows, 24-bit audio
files can be recorded with any compatible host application
that supports 24-bit recording.
AUDIODESK
AudioDesk is a full-featured, 24-bit audio workstation
software package for Macintosh included with each
PCIe-424 core system. AudioDesk provides multi-channel
waveform editing, automated virtual mixing, graphic editing
of ramp automation, real-time effects plug-ins with 32-bit
floating point processing, crossfades, support for many
third-party audio plug-ins (in the MOTU Audio System
plug-in format), background processing of file-based
operations, sample-accurate editing and placement of audio,
and more.
DIGITAL PERFORMER
The PCIe-424 system is fully integrated with MOTU’s
award-winning Digital Performer audio sequencer software
package.
OTHER AUDIO SOFTWARE
The PCIe-424 system ships with a standard WDM driver that
allows you to record, edit, play back and mix your projects
using your favorite WDM- and Wave-compatible Windows
software.
The PCIe-424 system also ships with standard Mac OS audio
drivers.
The PCIe-424 also includes an ASIO driver for multi-channel
compatibility with Steinberg Cubase and other
ASIO-compatible software.
A COMPUTER-BASED SYSTEM
Regardless of what software you use with the PCIe-424
system, the host computer determines the number of tracks
the software can record and play simultaneously, as well as
the amount of real-time effects processing you can apply to
your mix. A faster computer with more RAM and faster hard
drives will allow more simultaneous tracks and real-time
effects than a slower computer with less RAM and slower
hard drives. Standard third-party system acceleration
products can also help you achieve higher track counts.
