(1) Output Audio Quality
The FA2100CVR’s audio quality meets or exceeds the audio quality specified in
Chapter 3 of ED–56A and Part I of ED−112. Specifically, the Reference Signal is
1-kHz at 3 Vrms for the voice channels, and 1-kHz at 2 Vrms for the CAM channel.
The signal-to-noise plus distortion ratio (SINAD) of this signal when reproduced ex-
ceeds 24 dB (6 percent distortion) for the most recent 30 minutes of recording and
exceeds 20 dB (10 percent distortion) otherwise.
NOTE
: Refer to Table 3.1 of ED–56A and I−3.1 of ED−112 for other
applicable audio quality specifications including the
Speech Transmission Index requirement for various chan-
nels and segments of recording.
