04Apr DIY wireless audio: turning the Audio2000s into a wireless 2 channel portable audio system
I received an E-mail a few weeks ago from Shabazzr. He was wondering if I knew of any way to make the Audio2000s 6032uf UHF dual channel wireless system 100% battery powered. The wireless transmitters already run on batteries so I really just needed to find the spec’s for the receiver and a low price battery that would meet his requirements. After a little searching I found out that the receiver could run happily on anywhere between 12V-18V DC. I started looking around for a battery solution that would work for his application and found the Hype 61WH (5500mah) laptop charging battery pack. Shabazzr was kind enough to send me the above picture of his unit in action with the battery I recommended attached.
The Hype 61WH (5500mah) laptop charging battery pack comes with a number of different power plug adapters and has a very slim form factor. The size and thickness of the battery make it easy to simply velcro the two units together. The battery supplies enough power to keep the wireless system running for around 4 hours. The Audio2000s 6032uf UHF dual channel wireless system runs around $130 and the Hype 61WH (5500mah) laptop charging battery pack
is $37. So if you need 2 channels of wireless UHF audio and don’t mind the larger receiver unit, $170 isn’t a bad price. It’s much more affordable then the Sennheiser units I use.

The Tekkeon batteries work well, but the price of the battery is more then the wireless unit. If you want to spend that much you may as well upgrade to a nicer wireless audio system.

Does the Hype battery come with the charger? I don’t see it listed in the auction. I am interested in this battery but need to know how it compares to just getting pieces (RC Lipo batteries and and outboard charger).
thanks.

The battery charges through usb port.

What about one of these batteries?

I’ve run a number of things off of them.
Also, any idea on the sound quality of the Audio 2000s UHF system? I was considering getting it as well.

12 volts is the minimum power for the unit. Many times 12 volt batteries will drop to 11 or less during operation. If 12volts is the minimum it wouldn’t leave you much of a margin of safety. That’s why I recommended the higher voltage battery packs.

Are there any batteries like this for 12V-15V DC? I have a Nady Encore Duet system that I would like to buy a battery pack for.
Also, a quick wireless mic question: Is it generally necessary to upgrade the lav mic in a cheaper system to achieve better audio quality, or will this not make much of a difference? Thanks!

The battery pack in the picture has an adjustable power output, so if you adjust the output down the 16 volts you’ll probably be ok. If you don’t fee comfortable with that v-lock batteries supply 14.4 volts and have a very long life, but even used they are kind of expensive.
Upgrading your Lav should give you better audio but it still depends a bit on the lav and the transmitter.

You may be able to get the schematics for the Nady unit from the FCC. I was able to find the schematics for the Nady UHF-4 I have. (see http://transition.fcc.gov/oet/ea/fccid/ )
The 12-15V receiver input is regulated down to 9V with a 7809 regulator, which should give good regulation down to 11.5V in. But, since a battery is being used, the input voltage has no ripple, so it should still be usable at lower than 11.5V in. There would definitely be an issue if an wall wart with 60Hz ripple on it is used at that low of a voltage.
I suspect the Encore Duet has a similar internal power supply but don’t have the FCC ID to look it up.

That’s true. If he can open up the case and get a part number for the voltage regulator. It would be pretty easy to look up a replacement on digi-key and to adjust the input tolerance.

Have you been able to test the battery after several charges and discharges to see if it holds up well?

You’ll have to ask Shabazzr, He seemed pretty happy with it after about 5 charges, but not sure if he’s still happy with it after all this time.
