There is nothing worse than ordering a pa amp and then finding it makes a lot of noise. We have heard some sounding like a plane about to take off. The professional audio amplifiers shown below have been successfully used by us, or we have used models in the same series.
Most amps are two channel stereo power amplifiers.
When choosing pro audio amplifiers consider these points:
- Choose Speakon connectors to connect your speakers to the amplifier in mobile systems.
- Pick models that have short circuit protection, overload protection and thermal cut outs.
- Amplifiers with variable speed fans tend to be quieter in operation.
- Avoid amplifiers with only jack connections.
- True power output is the continuous output, usually measured in Watts RMS, not the peak music power often quoted.

Amplifier Power SuppliesA good quality power amp relies on a robust power supply. This means using a high quality transformer or an expensive switch mode power supply. The crown xls series power amplifiers offer excellent power output using light weight power supplies.
Extra processingTop of the range amplifiers include additional electronics to make powering your speakers safer and connecting your speaker systems easier.
Some amplifiers have built in crossovers allowing you to match the frequency response to the speakers connected to the amplifier.
Digital Signal Processing or DSP is used by some amplifiers to tailor an amplifiers output based on the type of event. For example, a rock concert requires a different style of sound to a corporate presentation.
Amplifier connectionsAn amplifier is not designed to have a direct microphone input, you need a mixer to use microphones with an amplifier.
In all cases you should read your instructions to check polarity of connections before use.
- RCA Phono - Allows connection direct from media players using standard rca leads.
- 6.35mm jack - Becomes less and less reliable with use, avoid using them if possible.
- XLR - Industry standard balanced audio connector, use these if you can.
- 6.35mm jack - Becomes less and less reliable with use, not good for high power outputs
- Speakon - Industry standard speaker connector, high quality connector.
- Binding Post - A common connector for speaker wire, only advisable in fixed installations.
- XLR - provided on some amplifiers to provide a link out to another amplifier.
