For example, you can mix four microphones with four stereo devices, or seven microphones with one stereo synthesizer. Phantom Power (+15V page 25 A single switch turns phantom power on to all mic inputs. Use this feature to provide power to condenser microphones. High-Quality Digital Effects page 22 The mixer's internal effector is in the same league as our SPX effector series, allowing you to create a rich range of variations with no external help. But of course you are also free to use the EFFECT OUT jack to connect to an external effector of your choice. MAIN and MONITOR Outputs page 23 The mixer offers excellent independent control of main and monitor output. The top panel offers separate main and monitor outputs, while the POWER AMP switch can be used to set the SPEAKERS jacks so that they output either the main signal to both speakers or else the main signal to one speaker and the monitor signal to the other. Separate MASTER control knobs and 7-segment graphic equalizers are also provided. Compressors (EMX512SC and EMX312SC only page 21 Compressors on channels 1 to 4 can be used to squeeze the dynamic range of inputs such as microphones and acoustic guitars, attenuating the higher levels and bringing out the lower ones. This feature helps reduce distortion and allows overall volume to be set higher, resulting in a stronger and more impressive sound. Tilt Setup or Rack Mount page 29 The EMX can be positioned at an angle or mounted in a rack, allowing for easy accessibility in a wide variety of setups. Internal Power Amp page 25 The internal amp makes it possible to connect the SPEAKERS jacks directly to non-powered speakers, with no need for an external amplifier in between. The rear panel offers two types of speaker connectors: phone jacks and Neutrik Speakon jacks. EMX512SC/EMX312SC/EMX212S 5
