Greetings,
Thank you for taking the time to read this.
I purchased a new Sony UWP-V1 package and I have a couple of questions for a sympathic forum reader.
Thanks,

I think It'd be best if you actually post your questions on here so that someone can help you.
 
Typically you would just lower the record volume on whatever you are recording on. If you tell us what your whole system looks (like what you are recording on), we can probably give you some useful suggestions.
 
We are recording on a Sony Handycam HDR SR-11 with a Sony UWP-V1 wireless microphone.
It works GREAT we are just having a couple of problems that I thought you could help me with.
1. It's too loud. When you are editing the video, you have to turn the audio down in each segment, and that takes too much time.
2. I am not sure what all the frequencies are for, and if we're suppose to be using a particular one. When we first got it, we just plugged it in and started using it, and it worked.
 
It probably wouldn't hurt to read through the manual for your wireless system. It will explain a lot of what each feature does, and why it is used.

The frequency agility is about being able to find a clean transmission path as you travel. Not every frequency may be free of interference in every place, so you need to choose one that is clear.

As for the volume level... this is where gain staging comes in to play. Every time there's a spot in the audio chain where level can be adjusted, that's a gain stage. The idea is to get each one optimized for best signal-to-noise ratio, and then to get the proper recording level. This can include proper level settings on transmitter, receiver, and camera. If the audio gets mangled at one stage, it cannot be fixed at any later stage in the chain.

"Too loud", by the way, can mean a lot of things. What program are you using to edit? Are the levels too hot on the meters in that program, or are they too loud on your speakers?

I took a quick look at the manual for your camera, and there's no mention of audio controls. It also does not appear to have an audio level meter on the LCD (please correct me if I'm mistaken here). That tells me that you're probably dealing with a non-defeatable AGC (Automatic Gain Control), which will kill the quality of your audio. AGC compresses the audio very, very harshly and keeps the levels peaking almost at 0dB, which is much too high. If this is the case, your best solution is a separate audio recorder.
 
I also have a Sony Handy Cam, mine is a HDR-XR520 and I absolutely love it! A problem I ran into recently was when I filmed an interview I picked up alot of background "noise". It was suggested I obtain a UWP-V1 wireless lavelier mic so it would not sound so amateurish. Do you agree?

The camera's built-in mic is useless, and adding an external mic that's mounted on the camera won't be much better. These are two truths that are often-repeated around here.

You need to get the mic off the camera and close to the dialog, be it with a wireless lav system or a boomed or stand-mounted wired mic (shotgun or hypercardioid). For seated interviews, a wireless lav system should do you fine. Just remember to listen - with headphones - while you record. That way, there are no surprises later.
 
With the Sony SR-11, you have an audio option to turn the levels down. As the OP found, they are "hot" if they are not brought down.

1. On SR-11's Viewfinder Press the Home button

2. At the bottom of the Viewfinder's touchscreen choose the 4th button/tab which has an icon of a car

3. Here you can change the Volume of your headphones. Turn it down below the halfway mark

4. Exit.

5. From the Homescreen touch the += icon in bottom right

6. At the bottom of the Viewfinder's touchscreen choose the 4th button/tab which has an icon of a car

7. Change MICREF LEVEL from NORMAL to LOW.

On the Sony Transmitter, make sure the Switch is set to MIC. Go into the menu and adjust the Attenuation while wearing headphones connected to the camera. You may also want to turn off the Transmitter and Scan for clear channels on the Receiver before you shoot to make sure that you're less prone to picking up RF. Here is the manual
