Page 2: Introduction
Audio Analogue to Digital Converter Introduction The 4410 module is an audio analogue to digital converter which may be fitted with one or two stereo ADC sub-boards, each providing four balanced or unbalanced digital outputs to AES3-1992. The digital outputs can be configured to lock to one of three references, video, wordclock or any valid balanced or unbalanced AES signal. - Page 3 Technical Manual 4410...

Page 4: Installation
Audio Analogue to Digital Converter Installation For module installation instructions please refer to the appropriate ICON rack frame section of the manual 2.1 Selecting a rear connector There are two alternative rear connectors provided. The K4410.3B is used for balanced signals, whilst the K4410.3U is used for unbalanced signals. Both occupy 30mm of rack width in the 1050 3U Icon rack frame. - Page 5 OP1- OP2- AUDL1+ AUDL1- 0P1-+ OP2+ AUDR1+ AUDR1- OP1- OP2- Not used Not used 0P1+ OP2+ AUDL2+ Not used AES REF IP - AUDL2- Not used AES REF IP+ AUDR2+ AUDR2- OP2- OP1- OP2+ OP1+ OP2- OP1- OP2+ OP1+ 4410...

Page 6: Configuration
Configuration 3.1 Setting reference options The 4410 digital audio encoder may be locked to one of three types of reference signal, analogue video, wordclock or any valid AES 11 signal. When locked to video, the line standard may be selected for 525 or 625 lines. In addition, the sample rate may be selected as 32kHz, 44.1kHz and 48kHz. -
