5. Operating Instructions
The JBL CBT 200LA-1 incorporates advanced features for precise sound control:
- Constant Beamwidth Technology (CBT): This patented technology provides true wide-band constant directivity coverage up to the highest frequencies, minimizing out-of-coverage lobing for consistent sound quality across the listening area.
- Vertical Pattern Coverage: The speaker offers selectable vertical patterns of 30° or 15°. Use the 30° setting for medium-throw applications and the 15° setting for long-throw requirements. Adjust this setting via the switches located on the speaker.
- Asymmetrical Progressive-Gradient Vertical Coverage: This setting directs more sound energy towards the far areas of the listening space, helping to achieve more consistent front-to-back sound levels. The extent of this gradient is adjustable.
- Dynamic Sonic-Guard: Integrated low-audibility overload protection safeguards the speaker components from excessive power levels.
- 70V/100V Transformer: The speaker includes a built-in 70V/100V transformer for distributed audio systems, providing 120W + 120W per module. Direct capability is also available.
