Objective 2 Amp Popping sound

post #1 of 36
Thread Starter 

Hi, I got my O2 a few days ago, and it was working fine for the first day.

On the second day i turned it on, used it for around an hour, and it cut off my audio and starting making popping sounds.

I couldnt get the audio to come out so i plugged the adapter and it started working again, until 30 minutes later it cut off my audio again and made popping sounds.

 

Anyone know what this means? Is it because im using a Razer Carcharias whilst I wait for my Q701. Or is it because im using my Samsung's External HD adapter which says, INPUT: 100-240V~, 47-63Hz, 0.65A Max.

Or maybe the battery?

Would really appreciate an answer. Thanks!

Do you mean it is making popping sounds when on battery power, but it works fine with the AC adapter ? Perhaps you just need to charge the batteries.

Normally there's a small 'pop' when it turns off.

As stv says, maybe the batteries need to be charged.

It works for a few seconds now, and then these abnormal popping sounds come in after cutting my audio, like someone is hitting 2 blocks of wood together at a high speed.

Do that happen when the amp is stationary or when it is on the move? If it is the later, it could be that the batteries ain't attached to the secure enough. You will have to remove the battery, make sure both negative (female) clamp of the battery and the battery socket are tighten just slightly so they will not move at all.

My guess is the battery is low.

You remind me of this: To the OP, what exactly is that Samsung adapter you are using? Is it actually an AC-to-AC?

Yep, I was thinking that should be the problem. You need an AC/AC (stepdown, basically), not a AC/DC. ODAC takes 14~20V AC. Using an AC/DC means only one of the two battery is charged, resulting in an imbalance in supplied voltage, which makes the popping noise.

Ok, the adapter i bought has just arrived and I plugged it in for around 30minutes and it's still popping.

Should I keep the amp on until the battery depletes and try recharge or should I just keep it plugged in overnight?

First, give us the link to the adapter so we know you didn't order the wrong stuff again. Second, it will take quite a long time to recharge the battery fully, longer than 30 minutes.

It was the adapter sold by JDS Labs so I would guess it's the correct one :s

Well, then adapter isn't the problem anymore. You just need to charge it up for longer.

Okay, I'll drop a reply tomorrow after it charges overnight.

Thanks :))
