What is the HF Button on the NT206L rear panel

When pressed in, a HF boost is activated. this adds additional HF extension needed for longer throws. When combined with adjusting the NT206L horn to 80 degrees, a highly focused HF response can be attained. With that in mind, adjusting the horn for the lower array items to a horizontal dispersion of 110 degrees improves coverage in the nearfield.

The combination of the HF Button and the adjustable horn allows for an effective way to optimize the line array in a matter of seconds.
