beachtek dxa-10 battery duration at DVinfo.net

Typically, how long does a 9 volt battery last in beachtek dxa-10 with 2 mics connected using phantom power for both mics?

I'm getting terrible results making this device useless.

Does anyone use this preamp with 2 phantom mics successfully?

Terrible results as in short battery life or terrible results as in bad sound?

My DX8A will only last about 3-4 hours on a battery doing two mics with phantom voltage before the battery drops to around 8v. When it gets below 8v, I start getting distortion. When doing a continous shoot, I replace the battery on the third tape just to be sure.

Yes, short battery life. A brand new battery died in 1 hour using 2 phantom powered mics, so after testing and setup time, I only recorded about 20 minutes of a 2 hour show.

The 1st 20 minutes sounded great.

How could I possibly use this device for any serious work if the record time is so short? I bought this device specifically to power the phantom powered mics. I can't plug the device into anything because it only takes one 9 volt battery, so it is basically useless to me.

The entire thing is a disaster.

That does seem short. Sure the battery was fresh to start with and that you used an long-life alkaline or lithium cell instead of a vanilla carbon battery? Is there an external power jack so you can rig up an external battery pack of some sort to power it so you can do a quick change between takes? (Don't know what you mean when you say you can't plug it into anything cause it only takes one battery.)

It was a new duracell battery. I just ran a test with another new Duracell battery and the preamp lasted for 80 minutes. The battery came out hot and dead.

I'll try a lithium 9 volt battery and see what the results are.

What I mean is it would be nice if I could just plug the preamp into the wall and not have to worry about batteries.

On the spec sheet it say the dxa-10 lasts for 4 hours without phantom power. It mentions nothing about the lasting time with phantom power.

Can you recommend a battery?

Would this work?

Perhaps this would be better and more suited:

Well I used the Home Depot Energizer Lithium battery. It passed with flying colors and lasted 3 hrs with time to spare.

If I had only knew earlier.
