ABOUT THE PCI-424 SYSTEM
18
channels total) at samples rates up to 96 KHz. At
176.4 or 192 kHz, this chip can process 48
simultaneous channels of input and output.
The custom chip handles all of the system’s I/O
processing, freeing up the host computer’s
processing bandwidth for real-time DSP effects
and hard disk I/O.
CueMIx DSP
The PCI–424 card features CueMix DSP™, a
flexible DSP-driven mixing and monitoring matrix
that provides the same near-zero monitoring
latency as today’s latest digital mixers. CueMix
DSP™ allows you to connect keyboards, synth
modules, drum machines, and even effects
processors and then monitor these live inputs with
no audible delay and no processor drain on the
host computer’s CPU. The CueMix DSP engine
resides on the PCI–424 card, so it works across all
interfaces connected to the card. The included
CueMix Console software provides an on-screen
mixer that gives you hands-on control of your
monitor mix, regardless of what audio software you
prefer to use. Digital Performer users have the
additional option of controlling CueMix DSP
directly within Digital Performer’s mixing
environment. CueMix DSP completely eliminates
the buffer latency associated with monitoring on
host-based recording systems.
Sample-accurate synchronization
The PCI-424 card’s standard 9-pin ADAT SYNC
IN connector provides sample-accurate synchro-
nization with all ADATs or other ADAT
Sync-compatible devices connected to the system.
For example, if you digitally transfer a single track
of material from the ADAT via light pipe into the
2408mk3’s Macintosh workstation software, and
then transfer the track back to the ADAT, it will be
recorded exactly at its original location, down to
the sample.
Video and SMPTE time code synchronization
The entire PCI-424 system, including all connected
interfaces, can resolve directly to SMPTE time
being received on any analog input in the system.
In addition, the 2408mk3 interface provides a BNC
video input for resolving the entire system directly
to video.
THE 2408MK3 INTERFACE
24 simultaneous inputs and outputs
The 2408mk3 I/O is a single-space, rack mountable
chassis with gold-plated analog and digital audio
connectors on its rear panel and status LEDs on the
front. The rear panel has seven banks of 8-channel
I/O at 44.1 or 48 kHz in the following formats:
■ One bank of 8 balanced (+4 dB) analog
quarter-inch (TRS) inputs and outputs.
■ Three Tascam DA-88 ‘TDIF’ 8-channel digital
I/O connectors.
■ Three Alesis ADAT optical ‘light pipe’ 8-channel
digital I/O connectors.
Three banks of 8-channel I/O at 44.1/48 kHz
Internally, the 2408mk3 has three 8-channel I/O
busses (A, B and C) for a total of 24 simultaneous
inputs and outputs at 44.1 or 48 kHz. Using the
included console software (available for both Mac
and PC), you can freely choose any I/O format for
each bank. For example, you can choose analog for
Bank A, ADAT optical for Bank B, and Tascam
TDIF for Bank C. Or you can choose ADAT optical
for all three banks.
Three banks of 4-channel digital I/O at 88.2/96
At 88.2 or 96 kHz, the 2408mk3 interface offers 4
channels of I/O per bank for the ADAT optical and
Tascam TDIF formats, along with 8 channels of 96
