Frequently asked questions
Is the 4739 a complete loudspeaker I can use alone?
No. The 4739 is the bass section only and requires a separate mid/high-frequency top section (sold separately) to form a complete ScreenArray system. It is designed for fixed cinema installations, not standalone use.
Does the Control 440CS/T work in existing 70V/100V systems?
Yes. It includes an integrated 80W multi-tap transformer with switchable taps (80W, 40W, 20W, 10W) for direct connection to standard commercial distributed audio grids, requiring no external transformer or dedicated amplifier channel.
Which one is better for live sound or concerts?
Neither is ideal for live touring. The 4739 requires a paired mid/high top and is fixed-installation only; the Control 440CS/T is ceiling-mounted for permanent commercial installations. Both are designed for fixed venues, not portable PA.
What is the key difference in installation complexity?
The 4739 requires professional integration into a ScreenArray cabinet stack and proper amplifier matching; the Control 440CS/T requires only a standard ceiling cutout and transformer tap selection for retrofit into existing drop-ceiling grids.
