Where is the amplifier located? Does it use batteries?

Amplifier is located in house between tv and antenna in cable (inline amplifier) . No batteries. Comes with AC to DC power supply.

It is up in the attic (2 stories). No batteries; think of it as rabbit ears in a plastic shell.

Umm, there's no battery and it plugs into your phone/computer/other electronic. The "amplified" it just something to catch your attention. they are a very good pair of headphones though, but the ear pieces are a bit small.Hope that helped :)

There is no battery. It uses an A/C adapter with a USB connection so it's electrical. I believe the answer to your question is Yes. I use it all the time walking all over the place. I've walked within 500 feet of the receiver before having the sound impaired. This of course will depend on the clear signal to the receiver.

Nop, just the amp and a battery without even a power cord, and it sound really noisy

The bike plays music, so there is a separate capartment for what I think are AAA batteries. The bike is ran mostly by the battery that is included. If you want it to play music you will need other batteries.

They sell power supplies at computer stores. Now they are small and can supply computer's, radio's, or MP3 players with power when batteries are gone. I would check "Power Supply" in Amazon. There you should be able to find a lot to offer you what you need at a good price.

size AA batteries is not included. I don't know how many hours in operation before changing batteries, I am using mine for almost 6 months now but I haven't changed my batteries yet. The moment you connect the device to the amplifier, that's the only time it uses power but once you disconnected it, it will stop using battery power. Device is recommended for low budget and the quality is just right for that amount.

Yes, it takes 2 AA Batteries but let me tell you I get around 120Hrs. +\- on a set of Alkaline Batteries. Also this Amplifier Really Boosts the Volume and it's Amazing clear, Very little distortion. I've owned mine for over 2 years..

it comes with a plastic battery pack that holds (8) AA batteries (batteries not included.. ) once the batteries are installed in the pack, the pack screws into the back of the amp.... Great little amp on A/C.. I have not used it on battery power though..

There is a battery compartment back there. I bought the adapter to plug in. in

It has batteries (4 AAs) but I don't see any place to plug in an ac adapter.

Not sure what you're asking here but the mixer is powered by an AC adapter. There are no previsions for batteries.

Just the amp in the box. You'll need a 9v battery and a male to male cord to go between your source and the amp.

Hi, It's a passive system, no battery involved. I'm going to install it today probably, more update in a few days about the sound.

I'm sorry I was unclear, you would need to attach a long line cord and put the amplifier in a window or doorway to be heard outside. It needs to be plugged into a wall socket and phone jack. It is not battery operated.

The amplifier is built into the box. You will need to run a remote wire (tells the amp to turn when you turn the car on), power wire from the battery, ground wire and RCAs.

It won't work with batteries. It has to plug in. It is fairly portable, but it doesn't seem to be what you are looking for. I believe Vox makes a practice amp that runs on batteries as well as Danelectro. Hope this helps.
