The Chandler Limited Germ 500 MKII Pre Amp is a one-unit preamplifier designed to be mounted in a 500-Series lunchbox. The device's components were redesigned from the original rack version to work with API's lower-voltage power standards and connectivity requirements.
The preamp features Germanium transistors in Class-A transformer-balanced circuits. The sonic benefits of Germanium transistors are that they exhibit the firm tonality of a solid-state circuit combined with the warm and smooth harmonic distortion characteristics of a tube.
The XLR microphone input, signal output, and power connections for this device are built into the separately available lunchbox rack enclosure into which the module connects. For direct input, the preamp also includes a switchable 1/4" TRS instrument connection on the front panel.
