Question: Can the TV audio out be connected to a receiver to play music files on a home sound system?
Document: To turn the screen back on you just touch the touch-pad.10. You can delete files and folders directly from the player. (Unlike that other really hip and popular player)The Cons1. The battery is nowhere near the rated life. This is a huge disappointment, especially from Cowon. They say 29 hours if you play 128 kbps mp3's with the screen off all the time and volume on 10. I played an audio book, that I ripped myself from the cd's, that's 24 hours long.
Lots of features. Great sound! However, equalizer does not work with FM radio, also does not play Audible.com files.
The volume is way too low. Played at its max (40) it sounds way off in the distance. I own two Cowon players, a D2 and J3. There volume has a max output to 50 but 25 to 42 is perfect volume. I can&#8217; judge the I Audio 9 sound because I can&#8217;t hear it.All my files are ripped into FLAC, that may be the reason for the poor volume.
excited as hell to receive a new cowon player and a set of headphones, loaded my music pressed play and was shocked. not shocked by how amazing cowons usually sound but by this weird hissing noises and distortion that swamped all my music. extremely upset and wondering if i should even buy another cowon product since their customer service is crap and their build quality seems to have taken a dive.
DO NOT PURCHASE THIS PLAYER!! !Originally I liked the player and would have given it 3.5 stars; this would have been my review:The audio quality is good, it is small and easy to hold. It has a long charge for music playback. I did not like the UI. It is all touch screen on the front which is not a problem but the navigation is somewhat difficult so the combination is annoying.
(There was no indicator in sight, and if there should have been any it was not mentioned in either the guide or the manual.) Preliminary setups taken care of, I proceeded to upload and sync music and playlists from Windows Media Player, as noted in the manual.Unfortunately, while the music files made the transition and were individually playable, the playlists did not. As my playlists include songs from many different artists, this was a big problem.
I was looking for a no thrills music player. This worked great for that purpose. I find the radio stations in my area suck, so having something to act like a radio was exactly what I wanted. Why not Pandora, Last.FM, etc? One, that gets expensive, and two, I drive through large areas with no service at all.This does amazingly well at what I wanted it to do. Would I recommend it for a media junky looking to play with songs all the time?
A handful of songs sounded like a CD scratching so I had to delete them and re-add them to the device so they didn't sound like they skipped. Other than that the audio is great. The different audio selections are amazing. I haven't used it for video too much but the few times I did it worked fine. I definitely recommend this and if/when I buy a new MP3 player I will probably buy from Cowon.
very good sound quality, I practice very long duration of bateria.muy recommended for people who like good quality music with. flac
Excellent unit. I love the volume and all the different sound settings. It holds all my music with room to spare, I've had this item for over a month now and I have no concerns.
Answer: Input on home sys is high impedance and TV out is low.  This could damage one of your devices.  I have done it with devices other than TV and stereo.  I would not do it for long or often.  Go to hi end  audio store and ask questions, don't let them give a simple answer.
