The Mackie Pro4FXv2 is a 4 channel analog mixer for live and in the studio. You make high-quality and silent microphone recordings thanks to the silent Vita preamps. Because of this, your recordings sound clear and are always usable. Add one of the 16 internal effects to make sounds sound fuller or more interesting. You choose from different types of reverb, chorus and delay effects. Create depth in your mix by adding a reverb or delay. On the master channel there is a graphical 5-band equalizer. This accentuates or removes frequencies so that the end result is in balance.
