1. MIC

The mono channels are equipped with Mackie’s cutting-edge XDRTM microphone preamplifiers; providing up to 60dB of rugged, low-noise, crystal-clear, phantom-powered am- plification. Their balanced circuitry rejects all manner of extraneous interference. Professional condenser, dynamic and ribbon mics will all sound excellent through these XLR inputs.

The inputs will accept almost any kind of balanced mic that has a standard XLR-type male mic connector.

2. LINE IN

The line inputs share circuitry (but not phantom power) with the mic preamps, and can be driven by balanced or unbalanced sources. These inputs can accept virtually any line-level signal, from -45dB up to +20dB.
