680 | Q74: There's a digital I/O connector on my jukebox. What is it good for? | ||
681 | A74: The Recorder models have a connector for digital audio output using the | ||
682 | common S/PDIF standard (Sony/Phillips Digital Interface). This jack is | ||
683 | not present on the Studio/Player/FM Recorder models. By using the digital | ||
684 | output in combination with high class external equipment, you can get | ||
685 | much better sound quality out of your jukebox, because you can use better | ||
686 | DA-converters and better amplifiers. | ||
687 | |||
688 | The Recorder and the FM Recorder models are able to record from digital | ||
689 | sources, too. The digital inputs don't have the 15kHz lowpass filter like | ||
690 | the analog inputs and you are sure to minimize the noise floor. | ||
691 | Generally, S/PDIF can be an electrical or an optical signal and there are | ||
692 | many devices that support both. There are even small 3.5mm sockets that | ||
693 | can take either an optical or an electrical cable. But the socket on the | ||
694 | jukebox is for electrical signals only! | ||
695 | |||
696 | If you want to connect your amp with digital input (RCA type) to the | ||
697 | output of your Recorder you need an adapter cable (3.5mm stereo jack to | ||
698 | dual RCA jack). Plug the 3.5mm stero jack into the digital I/O socket of | ||
699 | your jukebox and the red RCA jack (right channel) into the digital input | ||
700 | socket of your amp and that's it. You don't have to enable the digital | ||
701 | output. The sound settings on the digital output are always flat, your | ||
702 | volume, bass, treble, bass boost, loudness settings won't have any effect | ||
703 | here. | ||
704 | |||
705 | For recording digital signals on the Recorder, use the white RCA jack | ||
706 | (left channel) and plug it into the digital output of your CD player, MD | ||
707 | player or whatever. Don't forget to select digital input in the recording | ||
708 | settings. Note that there exist some adapter cables with different color | ||
709 | coding, so if output doesn't work the red jack try the white RCA jack, | ||
710 | too. The tip of the 3.5mm jack is the digital input, the ring is the | ||
711 | ouput. | ||
712 | |||
713 | For recording digital signals on the FM Recorder, you need a special | ||
714 | 4-pole 3.5mm plug (shaft = ground, tip = left channel analog line in, | ||
715 | first ring (next to tip) = right channel analog line in, second ring = | ||
716 | digital in). | ||
717 | |||
718 | If you want to connect devices with optical inputs/outputs, you need a | ||
719 | small converter box which converts your signal from electrical to optical | ||
720 | (for digital output) respectively optical to electrical (for digital | ||
721 | recording). | ||
