AES200
4개의 아날로그 오디오를 입력 받아 2개의 AES로 출력하는 장비
입력 : 4 x Analogue Audio
출력 : 2 x AES/EBU Analogue Audio to AES Converter
The AES200 is designed to convert analogue audio into AES/EBU digital
audio. It is handles four channels of analogue audio, converting them into
two AES/EBU streams.The conversion is performed to 20 bit resolution
with a 48KHz sample rate. The sample clock can be locked to either
another AES digital audio stream or an analogue video source.
The AES200 is part of our Series 200 range of interface produces. These
can be mounted in a 1U or 3U frame.
Inputs:
Audio - 4 x differential, line level, analogue inputs. Impedance 15K
Reference Video - Analogue video with sync. 625 or 525 line. This can be internally
terminated or left unterminated for passive T-looping arrangements.
Reference AES - Standard AES/EBU digital audio
Note - When using AES200 with an embedder the reference input, whether video or
AES, must be locked/derived from the SDV you are embedding into.
Outputs: 2 x AES/EBU digital audio as described in EBU Tech 3250-E (or AES-3-1992)
Specification: Conversion is perform by 128x oversampling, to 20 bit resolution.
THD+N -95dB approx
Dynamic range 105dB approx
Passband ripple 0.0025dB (20Hz - 21.7KHz)
Stopband attenuation -85dB (26.3KHz)
Control:
DIP switches set - Video line standard 625/525 or auto detect
Video reference or AES. (In absence it will free run)
Channel status bits for - no emphasis, 50/15 emphasis,
CCiTT J.17 emphasis and Stereo or 2 Channel mode
LED's indicate - AES/EBU ref present
Converter locked to video input
