First DIY project, Charlize problem
I recently bought a Charlize2 amp and after making all the solder connections am only getting sound from one channel, the left channel. The right channel is dead. When I turn on power to the amp which I measured at 12.57 vdc (I'm using a lithium-ion 11.1 v battery) I hear a distinct click from the left speaker and a fainter click in the right speaker. I did a continuity check from the mp3 player I'm using as a source up to where the input is soldered to the board. My eyesight is not the greatest but all the solder connections look alright to me. Is there a way to troubleshoot this - I don't have access to an oscilloscope. I don't see any physical damage to any of the components. (And of course have not seen any smoke from anything.) I don't suppose it would make any sense to take it to some type of audio repair, would it? By the way the MP3 player I hooked it up to was an iRiver model and have not seen any ill effects to the player from all of this.
Did you try diyparadise.com?
That is where Charlize is from. I am sure Yeo would be glad to assist you in getting it going. I have the original version and its a fantastic amp.
Thanks for the advice - I'll try that.
since you can hear a click on both speakers it looks like you may have a problem on the input part.
Did you check ?:
- Signal and ground are not reversed on both inputs ?
- Measure DC offset on inputs ?
- Bad interconnect connexion from your iriver (try moving the cable while playing) ?
Hope this helps.
