D-Top4:

Very high output

Incorporated digital amplifiers

Intelligent signal processing

Practical 90 degrees horizontal coverage

Narrow vertical beam: Less feedback risk

Less floor- and ceiling reflections:

Soundquality is less compromized by room acoustics

Increased authority, highly improved intelligibiliy at greater distances

Much better projection compared to conventional systems particularly in difficult acoustic environments!

Using 4 DIP switches some important settings can be changed.

The DIP1 high cut filter reduces feedback risk on condenser microphones.

DIP2 reduces mid and high for stand-alone applications.

And of course DIP3 and 4 may be used to reduce input sensitivity by 3, 6 or 9 dB.






D-Top4 has been designed for a vertical coverage of 8 degrees, and a horizontal coverage of 90 degrees, excellent properties for PA-applications for an audience up to about 300 persons within approximately 15x15m floor space.

The sub to be used in conjunction is the D-Sub12 (=D-Sat1 sub,1kW 12inch) or a D-Sub1.

The D-Top4 also makes an excellent in-fill or delay-top for events using a D-Top2 / D-Top3 each side. Additionally, the D-Top4 is very well suited as stand-alone PA for applications with low bass demands, such as presentations, workshops, etc.

This top uses two high efficiency (92dB/1w/1m) 6 inch mid speakers in a reflex enclosure. Average sensitivity is better than 95dB/1w/1m full space.
A state of the art switching amplifier delivers 300 watts of cold power into the mid section, and 120 watts into the high section. These amplifiers use a switching power supply for best mains efficiency and weight benefits. Newly developed smart processing ensures safe operating conditions for all drivers.
