What is the difference between a DSP and a conventional amplifier?

A DSP and an amplifier have different roles in a sound system, but are often used together.

A DSP processes the audio signal, while an amplifier amplifies the signal to drive the speakers.

What does a DSP do?

A DSP (Digital Signal Processor) is used to adjust and optimise the audio signal before it is passed on to the speakers.

With a DSP you can, among other things:

• Set crossover filters.

• Adjust time alignment.

• Tailor the sound using an equaliser (EQ).

• Control audio levels and signals between different channels.

What does an amplifier do?
An amplifier amplifies the audio signal and delivers the electrical power needed to drive the speakers.

Amplifiers are available with different numbers of channels and power levels, depending on which speakers will be connected.

Do I need both a DSP and an amplifier?
This depends on your equipment and what you want to achieve.

A separate DSP usually needs to be connected to an amplifier to drive speakers. However, amplifiers with built-in DSP are also available, combining both functions in one unit.

A DSP amplifier can be a convenient option if you want to improve the sound while keeping the number of installation components down.

For simpler sound systems, a conventional amplifier with built-in crossover filters may be sufficient.

If you want greater control over the soundstage and more advanced adjustment options, a DSP or DSP amplifier may be a better choice.
