    Hello all! I'll give some quick background because my situation is different than most posts on the forum. I work for an art museum that often shows video works. (My job title is Chief Preparator, something I'd never even heard about before I got the job! I've been here 6 years now and love...
  2. Screens
    Room size: 14' x 18' x 7' First row to screen: 8' Second row to screen: 14' Projector to screen: 13' Sony 1080p Projector I am wanting to upgrade my screen to something larger, currently have a 100" Screen Innovation Slate with .8 gain (not ideal I'm sure for a light controlled room). Really...
  3. Receivers, Amps, and Processors
    There's no particular problem, I just want to learn if I'm doing this as best I can with regard to the health of my equipment and standard practice. From my untrained ears, I've perceived no different in quality when changing the way each stage deals with gain to obtain the final, desired...

    I am adding a projector to my pool deck. I have already invested a lot of money in four speakers for my pool deck. I am trying to utilize them. It kind of works, but I have a serious sound level issue. I have attached the complicated diagram. I am tapping the sound from my receiver, then...
  5. Subwoofers, Bass, and Transducers
    Hi everyone! I just bought a second hand REL R-528SE. I noticed that the LFE input gives me very low output compared to the High Level input (speakon). Where the high level volume control is dialed in at the 10 o'clock position the LFE volume is dialed in at the 2 o'clock position to get a...
  6. Receivers, Amps, and Processors
    What is the relation between amplifier RMS/peak power, source level and the speaker power rating? Let's say 8 ohm speakers could handle 100 watts by the spec. The amplifier puts out 300W/8Ω of continuous power per channel with a peak of 450W/4Ω per channel. If the amplifier gain is set to 1/3...
  7. DIY Speakers and Subs
    Hi, I'm reading up on setting the gain structure in the signal chain, it's especially important when you are mixing pro and consumer gear. Am I understanding this correctly: 1) Zero out all AVR trim levels. 2) Set AVR to 0dB, play a 0dBFS sine wave at various frequencies and ensure the input...

  9. Digital Projectors - Under $3,000 USD MSRP
    Dear, I tried to build a formula that would allow me to choose the right projector according to the desired screen size, the available throw distance and the light level of the place. The following is what I think I should do as a calculation. When I do it, the result is strange and not the...

  11. Screens
    Hello AVS people, I just created an account because I've been researching screens this week. After projecting onto my white wall for the past year I've decided to get a projection screen to up the image brightness and take away some of the bumpiness of the wall image. I almost bought the first...

    Our school purchased a used HD6K to be used in the gym for film nights. The expected audience is about 200 people. We need to buy a screen to match the projector. What is the optimal size and gain for the screen? We would like to have it large in order to give a real theatre effect. The...

    I'm in the process of remodeling my basement into a pseudo home theater setup and I need to figure out where the outlet should go on my ceiling. The projector I'll use is a JVC RS4190. I'm aiming for a 130" 2.35:1 screen (so about 104" in 16:9), and I'll be using the lens memory feature to...
