IQBADX Four Channel Analog and D1
AES/EBU Audio Data Extractor
Module Description
The IQBADX extracts four audio pairs from SDI
video (D1 - 270MBit) to four analog and four
AES/EBU outputs. 20-bit digital to analogue
conversion ensures high audio signal quality.
A crystal locked PLL ensures low output jitter.
The analog audio output level is adjustable
b12 and +24 dBu for 0 dB FS in via preset
trimpots. Extraction may be from any group and
pair independently for each channel-pair.
Extraction is fully compliant with SMPTE 291M and
SMPTE 272M-A for synchronous-to-video audio at
48 kHz.
When audio data is absent from a selected
channel-pair address, the output will be silence or
tone (selectable).
The SDI input is equalized to > 200 m of cable.
Full EDH monitoring is included. All analogue audio
connections are via a 25 way D connector. AES
connections are balanced via a 25 way D
connector (-D versions) or unbalanced BNC (-B
versions).
