Signal processors are devices that modify, adjust, or enhance audio signals before they reach the amplifier or loudspeakers. They allow control over volume, dynamics, mixing, delay, and sound quality, adapting it to each space and situation. Some operate automatically, while others require manual intervention, but all play a key role in the audio chain.
This section explains the main types of processors and their functions: from mixers and preamplifiers to compressors, delays, and feedback control systems.
Good sound is not only transmitted — it is also processed to be heard as it should.
{accordion title="What is a mixer and what is it used for?" open="false"}
It is a device that allows you to combine multiple audio signals into a single output. Each channel can be adjusted in volume, equalization, and panning.
It is used to control multiple sound sources simultaneously, such as microphones, instruments, or players.
{accordion title="What is a preamplifier?" open="false"}
It is a circuit or device that boosts very weak signals (such as those from a microphone or instrument) to a suitable level for processing by other equipment.
It is the first step in the audio chain: it prepares the signal without distorting it.
{accordion title="What is delay in audio?" open="false"}
It is an effect that reproduces a signal with a certain delay, creating echoes or repetitions, or compensating for the distance between loudspeakers.
In public address systems, it is used to synchronize message playback across widely spaced speakers, improving overall speech intelligibility.
{accordion title="What is feedback or the Larsen effect?" open="false"}
It is a phenomenon that occurs when the microphone picks up the sound from the speaker, amplifies it, and re-emits it in a loop.
It produces a sharp and unpleasant whistle. It can be avoided with proper placement, equalization, and gain control.
{accordion title="What does an audio compressor do?" open="false"}
It reduces the difference between the loudest and softest sounds, keeping the volume more consistent.
It prevents sudden peaks and improves sound clarity, especially in voices and dynamic instruments.
