Title: UA-5 AC input question
Post by: JiB97 on January 03, 2006, 05:44:43 AM: I have been powering my digi-mod UA-5 with a Memorex 7.2v battery, and when I tried to run it off of the Roland AC adaptor that came stock with the UA-5, it didn't work. Has this every happened with anyone? Could it be because the AC adaptor is feeding it 9v instead of 7.2? I'm kinda clueless. :-\

Check your AC adapter w/ a multimeter and make sure it is working properly.

7.2 is fine...I've ran mine on 7.2 and 9.

Come to think of it, I don't think my stock AC plug works either. :-\

Will do. Strange thing is, I used to run the UA-5 solely off of the AC adapter before i got the battery. :-\

Check that you've got the correct AC adapter. It is : negative center, positive surround (9V DC).

This is the opposite of the standard AC adapters!!!

Ya, i checked that. It is the AC adaptor that was included with the UA-5, whcih is why I don't understand why it won't power it up now.

Post by: dnsacks on January 03, 2006, 04:39:33 PM: providing pure dc power (from a battery) will likely result in better sound quality than would be obtained if you powered the ua5 via the ac adaptor . . . . . fwiw

Post by: Teen Wolf Blitzer on January 03, 2006, 06:29:03 PM: I bought a new digimod from Doug a year and a half ago or so and the wallwart was bad. Doug replaced it. Just an FYI. Maybe this is common?
