AV Rack and Speaker System

THIS PAGE NO LONGER MAINTAINED

Intro

To augment the screen array, the Video Wall will have an audio system in addition to a lineup of various video input devices. Below is a preliminary list of peripherals I've compiled that will be included in the audio and video racks. Product suggestions will be listed as they are researched.

Useful Specifications, Numbers, and Math

• 16 NEC X462-UN displays (3-year stock parts and labor warranty)
• 1366 x 768 native resolution (WXGA - 1080i/p will scale down, 720p will scale up)
• 5464 x 3072 total resolution (16.79 MP)
• 7.33mm total gap between each display (including bezel width)
• 40.4" x 22.8" x 5.0" (each TV, 1" beyond wall recess)
• 945lbs / 428.9kg total monitor weight (59.1lbs / 26.8kg * 16)

• 14.75" gutter on each side of array (for speakers?)

Audio

• Speakers (Mains)
  • JBL CBT 70J+70JE System:
    • Good: Adequate frequency range and power. Comes with mounting brackets to sit flush against a wall.
    • Bad: 9.3" deep, which could be problematic, but would likely align with the fronts of the TVs. Require amp/preamp and a mixer if we're wanting to send multiple audio sources (eg. music with a mic feed).
    • Price: ~$3,000 (MSRT, rounded up) for a pair.
  • JBL CBT 100LA:
    • Good: Fits the space well. Good vertical coverage. Comes with mounting brackets. Will sit flush without a problem.
    • Bad: Weak bass and mid-bass. Require amp/preamp and a mixer if we're wanting to send multiple audio sources (eg. music with a mic feed).
    • Price: ~$1,500 (MSRT, rounded up)

• Subwoofer (necessary?)

• Amps
  • Mackie FRS Series
  • Harman Kardon
  • McIntosh (hi-fi, probably not necessary, but they sure are nice to look at)

• Preamps
  • Denon DN-A7100
  • Gemini PA-7000
  • Aphex 188

• Power conditioner (maybe?)

• Mixers (eg. for presentations - microphones, etc.)
  • Mackie PPM Series

Video

• Bluray Player

• PS3 (in lieu of dedicated bluray player)

• AppleTV:
  • Good: Mind-numbingly simple for streaming video and music. Could be useful for streaming videos from Purdue's Youtube account. Netflix. Can be jailbroken to use XMBC. Previous generation AppleTV offers local storage.
  • Bad: Video output limited to 720p. Supports few video formats.
  • Price: $99.00
