1-2 Major Features
Analog Wideband, Multi-Channel
The standard SIR-1000W configuration is 4 ch
×
160 kHz, and when combined with the
SCX-16W channel expansion unit, 16 ch
×
40 kHz analog data can be recorded and played
back.
LSB Digital Channel
The recorder has function to perform recording and playback the digital signals of 1ch
(
768 kHz) to 4 ch (192 kHz), along with analog signals concurrently.
Handy Subchannels
In addition to the above analog channels and LSB digital channels, the recorder is
equipped with the subchannels listed below to allow various types of subdata to be
recorded or played back together with the analog and LSB data.

Voice channel
AUX analog channel
AUX digital channel
Application

Bit Stream Data Recording/Playback
A dedicated bit stream board can be inserted into the recorder’s rear option slot, allowing
up to 8 channels of bit stream data to be recorded and played back separately from and
faster than the standard AUX digital channel. The sampling frequency during simultaneous
recording with analog data is 12 MHz (one channel mode, normal speed), and for digital
data only (analog off), 24 MHz (one channel mode, normal speed). There are two types
of bit stream boards, asynchronous (SBS-10A) and synchronous (SBS-10S).
Large Capacity AIT Cartridge
Up to 25 GB of data can be stored on an AIT cartridge the size of an 8 mm video tape. The
cartridge size is small (95
×
15
×
62 mm) and takes up little storage space.
The newly developed AME tape undergoes Diamond-Like Coating (DLC) processing to
endow it with superior surface durability so that data recording has extremely few drop-
outs.
High-Quality Recording and Playback
16-bit linear quantization provides a dynamic range of 76 dB or more within a bandwidth
of DC to 40 kHz. The interchannel phase difference is also kept at 2 degrees or less. The
analog input level allows up to ±133 % of the input range values, and the input DC offset
can also be adjusted automatically or manually for each channel within a range of ±100%.
