At least all my cables and my headphones are wired this way. btw: sorry for my poor english, I hope it is nevertheless understandable. Correct it if necessary. Here's an updated version: Question: 74. There's a digital I/O connector on my jukebox. What is it good for? Answer: The recorder and FM recorder models have a connector for digital audio output using the common S/PDIF standa1rd (Sony/Phillips Digital Interface). This jack is not present on the Studio/Player models. By using the digital output in combination with high class external equipment, you can get much better sound quality out of your jukebox, because you can use better DA-converters and better amplifiers. The recorder (not the FM recorder) is able to record from digital sources, too. The digital inputs don't have the 15kHz lowpass filter like the analog inputs and you are sure to minimize the noise floor. Generally, S/PDIF can be an electrical or an optical signal and there are many devices that support both. There are even small 3.5mm sockets that can take either an optical or an electrical cable. But the socket on the jukebox is for electrical signals only! If you want to connect your amp with digital input (RCA type) to the output of your jukebox you need an adapter cable (3.5mm stereo jack to dual RCA jack). Plug the 3.5mm stero jack into the digital I/O socket of your jukebox and the red RCA jack (right channel) into the digital input socket of your amp and that's it. You don't have to enable the digital output. The sound settings on the digital output are always flat, your volume, bass, treble, bass boost, loudness settings won't have any effect here. For recording digital signals, use the white RCA jack (left channel) and plug it into the digital output of your CD player, MD player or whatever. Don't forget to select digital input in the recording settings. If you want to connect devices with optical inputs/outputs, you need a small converter box which converts your signal from electrical to optical (for digital output) respectively optical to electrical (for digital recording). Note that there exist some adapter cables with different color coding, so if output doesn't work the red jack try the white RCA jack, too. The tip of the 3.5mm jack is the digital input, the ring is the ouput. Received on 2003-06-04 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
