OPERATING INSTRUCTIONS FOR THE INT202 FIREWIRE INTERFACE
Page
21
Date: 03/10
Technical Data
Digital Inputs:
-
(2) Firewire connectors
-
Sampling Frequencies: 44.1, 48.0, 88.2, 96.0, 176.4 or
192kHz
-
Maximum input wordlength: 24 Bits
Digital Outputs:
-
(2) XLR connectors
-
(2) RCA connectors
-
Professional Channel Status Data on the XLR and RCA
outputs
-
Dual wire mode: channel 1 (left) on OUT1 and OUT3,
channel 2 (right) on OUT2 and OUT4, active at 176.4 or
192 kHz sampling rates only.
-
The unit has to be power cycled in order for any mode
change to take effect (dual / single wire)
Synchronization:
-
Synchronized via the clock internal to the INT202, i.e. the
computer is slaved to the INT202
-
Extremely efficient Jitter attenuation down to subsonic
frequencies
-
Sampling Frequencies: 44.1 kHz, 48.0 kHz, 88.2kHz,
96.0kHz, 176.4khz, 192kHz
Power:
Bus power from the Firewire connector or power from an
external power supply, 8…12V / 0.2A
Level Control:
With the (optional) Remote Control unit the gain can be
controlled between 0dB and –60dB:
From 0dB to –20dB in 0.5dB steps and from –20dB to –60dB in
1dB steps. In the 0dB gain position the INT202 is fully bit
transparent, i.e. it does not change the data in any way. In all
other gain positions the output signal is properly dithered to a
wordlength of 24 bits. All units are shipped with a 0dB gain
setting and non inverting phase setting, i.e. when there is no
remote control included the unit is in fully transparent mode.
Bit Transparency check:
Allows to check the bit transparency of the player program
running on the computer. All standard sampling rates at 16 or
24 bit wordlenghts are supported.
Phase Control:
With the (optional) Remote Control unit the absolute phase of
the audio signal can be controlled between 0° (not inverted)
and 180° (inverted).
