NTP 560A-100A A/D - D/A Converter 2000s - black

560-100 A/D - D/A Converter FEATURES u 1U frame complete with Power Supply, synchronization unit and up to 4 stereo A/D or D/A converters in any combination. u 18 bit, 64 times oversampling, Sigma-Delta A/D converters. Dynamic range > 100 dB. Channel Separation > 100 dB over the entire frequency range. u 20 bit D/A converters. Dynamic Range > 104 dB. Channel Separation > 100 dB over the entire frequency range. u Inputs of the A/D converter and outputs on the D/A converters are balanced and fully earth free - yet transformerless - with separate DC/ DC power supply. u Digital inputs and outputs are AES/ EBU types. u A/D converter synchronizes on an external AES/EBU reference-signal or on the internal oscillator. u Synchronization signal may be daisy-chained. u C bit or U bit can be programmed in an EPROM. DESCRIPTION This 560 A/D and D/A converter for AES/EBU signals has been designed as a selfcontained unit that can hold up to 4 converters. The 1U x 19" box is split into 5 sections of which 4 sections can be either a A/D- or a D/A-converter. The 5th section includes a mains supply and a common synchronization unit. Each of the converts includes a PCB with frontplate and LED’s for status indication and a rearplate with 3 XLR connectors for external connections. The physical dimensions of an A/D are the same as for a D/A, so they may easily be interchanged. The front LED’s on the 560-110 A/D Converter indicate sampling frequency the unit is working and at whether an external or the internal clock is used. The D/A converter includes a 20 bit D/ A-converter, an analogue filter and a de-emphasis circuit. The 560-120 D/A Converter will lock to the incomming AES/EBU signal provided that the sampling frequency is 32/44,1/48 kHz, within 4%. The LED’s will indicate if the converter is synchronizing or not, and show the content of the most important status bits. On the front of 560-130 Synchronizing Unit, a switch is used for selection of internal or external synchronization, and another switch is used for selecting the internal sampling frequency: 32, 44.1, or 48 kHz. A LED marked ‘EXT LOCK’ will be steady lit if the incomming sync. signal is accurate within 400 ppm, and it will flash if the accuracy is within the max. range of 4
