Stand-alone Format Conversion
Finally, several additional LEDs, along with
accompanying set/select buttons, allow you to
access the 2408mk3 I/O’s stand-alone format
conversion features. With these controls, you can
bounce any I/O format to any other format without
a computer.
Headphone output
The 2408mk3 front panel includes a quarter-inch
stereo headphone output jack and volume knob.
The headphone output matches the main stereo
outs, which have their own volume knob.
THE 24I/O INTERFACE
24 analog 24-bit/96 kHz inputs and outputs
The 24I/O is a single-space, rack mountable chassis
with gold-plated analog audio connectors on its
rear panel and level meters on the front. The rear
panel has 24 gold-plated, balanced +4dB TRS
analog inputs and outputs with 24-bit A/D
converters. All inputs and outputs can be accessed
simultaneously. Internally, the 24I/O has a 24-bit
data path to and from the computer so that all
audio data is carried to/from the computer in 24
bits.
Converters
All analog-to-digital and digital-to-analog inputs
on the 24I/O are equipped with 24-bit, 128x
oversampling, extremely high-quality,
latest-generation converters.
Word clock in and out
BNC Word clock connector can be programmed
via software for either input or output for synchro-
nization with standard word clock devices.
Level Meters
The front panel of the 24I/O displays 48 level
meters, arranged in three banks of 8 channels. For
each channel, there is a five-segment meter that
measures from -42 dB to 0 dB.
The clock section in the middle of the front panel
indicates the current sample rate.
THE HD192 INTERFACE
High definition audio recording
The HD192 provides the very best A/D and D/A
conversion available. It can operate at any standard
sample rate from 44.1 kHz to 192 kHz.
12 analog inputs and 12 outputs
The HD192 I/O is a two-space, rack mountable
chassis with XLR audio connectors on its rear
panel and level meters on the front. The rear panel
has four banks of I/O in the following formats:
■ One bank of 12 XLR inputs
■ One bank of 12 XLR outputs
■ One pair of AES/EBU stereo digital I/O
connectors
All analog inputs and outputs can be accessed
simultaneously.
AES/EBU digital I/O
The HD192 rear panel includes an AES/EBU stereo
digital input and output. Both of these connectors
are capable of handling 24-bit digital audio at
sample rates up to 96 kHz. The AES/EBU input and
