Low impedance speakers

Impedance is the effective resistance of an electric circuit or component to alternating current, arising from the combined effects of resistance and reactance. Here we explain the features of low impedance and how it is implemented in a speaker system.

Active speakers

Active speakers contain their own amplifier to drive the speaker, which will be matched by impedance and power handling. This makes them a simple solution for distributed audio systems.

Dispersion angles

Each ceiling speaker in an installation is capable of effectively providing coverage to an area defined by its dispersion angle. Here we show how to calculate the spacing of speakers to cover your installation

Speaker system types

Our speaker and amplifier products cover many environments and applications with a focus on clear and efficient sound coverage. Here we discuss the different types of systems

IP ratings

IP (or "Ingress Protection") ratings are used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc) and moisture.

Glossary of terms

Microphones guide

Whether on stage, in the studio, place of worship or a conference, choosing the correct microphone for the job will be the difference between being heard and being heard clearly.

Dynamic vs condenser microphones

The way that a microphones picks up sound determines how useful the resulting audio output is for different applications. There are 2 main types of capsule used in microphones – dynamic and condenser.

Zoning Systems

Zoning systems are flexible sound systems that provide control for the sound that is delivered to different areas, called “zones”.

Balanced or Unbalanced Signals?

There is much confusion about balanced and unbalanced audio signals and how they differ. In order to understand this, we need to cover the basics of audio signals and how they are made.
