Mixer Audio


A mixing console is an essential purchase on the road to build a Radio Studio.

The Audio Mixer Console is often call mixing desk or broadcasting desk.

The audio console is the heart of the studio; it’s used to control anything that the listeners hear on air. There is an input for every channel.

The slider on the audio console amplifies the incoming signalfrom a variety of sources, mixes them and route it to a unique output.
The Mixer Console will allow to seamlessly, without a break switch from a computer, a Turntable and/or CD player, Microphone and a Hybrid Phone input, smoothly, without interruption, and it will consistently produce the audio that you expect.

Broadcast Radio Audio Consoles are classified in two types:

  • PA (public address), Live Mixers Sound designed for Musician Studio or Live applications
  • Broadcast Radio Consoles designed specificallyfor on-air talent ease of use.

When you turn a microphone on or off, a Broadcast Radio Console will mute any speakers and illuminate an “on air” light. When you turn a CD Player, Phone or Computer channel on, often it will “trigger” that input so it starts playing immediately.

While Analog audio consoles have the physical audio flow directly through the console’s circuitry, many radio stations now use Digital Audio Consoles

It ultimately depends on the budget if whether direct to a Studio or PA Live sound Mixer, an Analog or Digital Professional Broadcast mixer console.
