Main features of the AC2496
Model 5045 (8 channel AD card)
This is an 8 channel AD card for extending the AC2496 ana-
log inputs to 16 channels.
Model 8355 (8 channel AES/EBU card)
This is an 8 channel AES/EBU card for converting the ana-
log input signal to AES/EBU digital signals. This card makes
it possible to transmit 24 bit/96kHz digital signals that could
not be output in adat format.
The AC2496 is a professional use high quality 24 bit, 96kHz compatible 8 channel A/D converter for
converting analog signals to digital signals. Conversion to digital signals can be selected for S/P DIF or
adat, depending on the application. Furthermore, by installing the option, it will be possible to also
output AES/EBU format digital signals so it can be used to extend the number of digital multirecorder
analog inputs and to substitute the inputs of digital mixers and audio cards in personal computers.
• Options available for extending functionality
Two exclusive options are available for the AC2496
which further extend the AC2496’s capabilities.
• Balanced/unbalanced compatible input connectors
Stereo phone jacks that comply to both balanced
(+4dBu) and unbalanced (-10dBV) lines are employed
for the analog inputs (1-8).
• Optical digital output connector (DIGITAL OUT)
Adat or S/P DIF digital signals (by switch) can be out-
put from the optical (square) digital output connec-
tor. This can be connected to external digital equip-
ment provided with input connectors for adat or S/P
DIF signals.
• Includes with WORD in/out connector
Synchronizing external equipment with the WORD
clock is possible by utilizing this WORD IN/OUT con-
nector.
• Reference level can be set to match the input
The reference level can be set to match the analog
input (balanced or unbalanced line). The reference
level can be chosen from three different levels: -12dB,
-18dB or -20dB. All channels can be switched simul-
taneously.
• Selecting various digital formats
Four different digital formats can be selected: 24 bit/
44.1kHz, 24 bit/48kHz, 24 bit/88.2kHz and 24 bit/
96kHz. When outputting adat digital signals, how-
ever, it will be limited to 24 bit/44.1kHz and 24 bit/
48kHz.
<Notes when setting the reference level>
Be sure to match the equipment level for both
balanced and unbalanced lines in regards to
both the reference level and the analog input
connector of connected equipment.
For example, if it is used with the REF LEVEL
switch set to balanced line reference level, digi-
tal clipping and low S/N signal may result if an
unbalanced input is connected to the input
connector.
