Digital I/O
All digital signals are converted to and from MADI format via the DM714 AES/EBU to
MADI Converter, the MD704 MADI to AES/EBU Converter, and the Modular I/O
Format Conversion
The FC726 is a bidirectional device with 56 channels of sample-rate-converted I/O. In addi-
tion to AES/EBU I/O, the FC726 allows direct connection to several third-party digital
formats. Formats supported by the unit are TDIF, SDIF-2, and ADAT Optical.
AES/EBU outputs are alwasy active even when using third-party formats.
1.4 Microphone Inputs
Microphone inputs are handled by the ML530 Mic/Line Interfaces and Modular I/O re-
preamps. Each ML530 unit contains 24 remote-controlled mic preamps, and is connected
to a deditcated AM713 Analog to MADI Converter. Up to seven ML530s may be con-
nected in a system.
Each Modular I/O frame can contain from 4 to 32 remote-controlled mic preamps. Up to
seven Modular I/O frames can be deployed in a system.
The AM713 and MA703 are 24 channel I/O devices with four additional auxilliary chan-
nels. The first two Aux channels are always analog and the remaining two comprise a
digital pair in AES3 and S/PDIF format. Note that one or the other format can be used,
but not both simulataneously. The Modular I/O frame can handle up to 64 signals.
DD9xx series AES I/O, input, and output cards. The DM714 and MD704 converters han-
dle 12 AES/EBU pairs (24 channels) of digital audio and four additional auxilliary chan-
nels. The first two Aux channels are always analog and the remaining two comprise a di-
gital pair in AES3 and S/PDIF format. Note that one or the other format can be used, but
not both simultaneously. All digital inputs of the DM714 have built in Sample Rate Con-
verters. The Modular I/O frame can handle up to 64 signals. All its digital input cards
have built in Sample Rate Conversion.
Embedders/De-embedders
The Modular I/O frame can be fitted with cards that can embed or de-embed 4 or 8 channels
of audio to/from a single SD or HD video signal as per the SMPTE272M standard. Audio
from MADI can be embedded to an SD or HD video signal, and audio from an SD or HD
video signal can be de-embedded to MADI. Each Modular I/O frame can handle up to 64
audio channels. An Embedder/De-embedder card
cannot
embed and de-embed audio simul-
taneously.
