The Purple Audio Pants 500-Series Preamp is a four opamp, diferential microphone preamp designed to work in standard 500-Series racks.
The Purple Audio Pants 500-Series Preamp uses a unique dual-bobbin input transformer from Cinemag unlike any other. The smooth Gain control helps you dial in the sound you want. If the output level is too high, you can ride the level down with the separate Level control. Pressing the "High" switch changes the feedback network to provide an insane 78dB of clean gain, a great match for very low output mics. With different Gain, High mode switch, and Level settings the Pants can produce many different tones with the same amount of output level. The front panel DI goes through a FET buffer into the input transformer, adding an extra dimension to the sound of the preamp. The DI load switch gives you two options, making it even easier to get the best direct tone for your instrument. Two LEDs clearly indicate signal level for the gain and output stages at a glance, turning green to indicate signal present, yellow for 10dB below clipping, and red for clipping. The Pants uses two KDJ3 opamps and two KDJ4
