The 600mhz range in the states has been bought up and wireless mic systems have to migrate to over frequency locations. I think 500mhz band is not the place to go. Hoping to have this added as a huge help to my AV profession. ### 4/5 — Solid app *2017-01-17* Great app for simple equations and quick results. Love the pinout section. Would be great to add a few other connectors like speakon NL2, 4 & 8. Also, wiring from different connectors (TRS-XLR etc.) ### 4/5 — Excellent - Could Use More Custom Options *2014-08-21* This app is very well done! It provides a ton of information and is very well laid out. As far as I can tell, all the information as accurate. I do wish I could specify some custom settings, especially in the tone generator and aspect ratios. The tone generator has presets but I can't set a specific frequency. Likewise I can't specify a custom aspect ratio, though it will tell me what the AR is of any given size. ### 5/5 — Great App *2014-02-27* Good App easy to use, Handy to have! ### 5/5 — Awesome for any av tech to have *2012-09-07* This app is great, it does so many things, and does them well. It would be worth it just for the lens and audio delay calculators. A fantastic reference app that any tech should have, especially for the price. ### 1/5 — Waisted money *2012-07-26* Just purchased this app for my IPad 5.1, There seem to be no settings options. Everything seems to be measured in meters and this cannot be changed. I live and work in America and should be forced to do the extra conversion every time. Select Tone Generator and the App Closes! I have free Apps that work better than this. I wish that there were some way that I could return this and get my Money Back!!! ### 3/5 — Tone Generator Problems *2012-07-07* I can't get the tone generator to work. I'm on a 3GS iPhone. Please fix Thanks ### 5/5 — Worth the money! *2012-05-01* I really love all the different connectors you have the pin outs for. The aspect calculator didn't seem to work for me. Even with that it's still 5 stars in my book. ## Frequently asked questions about AV Tools ### What is AV Tools?
