Chandler Limited GERM 500 MKII User Manual

Thank you for purchasing the Chandler Limited Germ 500 MKII. The Germ 500 is an updated version
of our original Germ 500. This unit has an improved faceplate layout and nicer look. It uses classic
germanium transistors in all class A, transformer balanced circuits. The Germ 500 MKII is our
well-known Germanium Preamp adapted for 500 series racks. We use the same transformers and amp
blocks to assure the sound is consistent with our rack version. We have updated the power on the
MKII so there are no power-up issues with current lunchboxes and rack systems.

Please feel free to call our shop anytime for help or with questions.

POWER SUPPLY RECOMMENDATIONS­With ANY 500 modules (not just the Devils) we recommend using a rack with external supply. We feel
a power supply in such close proximity to the right hand slots of the rack can cause hum and noise
oor issues with many modules by many manufacturers. For this reason we mainly recommend the
API 500v rack with external L200 supply and the BAE 11-slot with external supply.

NOTES on BAE racks:
We recommend adding a wire from Earth to power supply common on all BAE racks. In many cases
hum can be avoided and Earth to common is standard procedure on most electronic equipment.

FEEDBACK - The Feedback control is essential to the sound and function of this pre amp. It aects
the sound and function of the amplier in many ways. THD, frequency response, and gain change
considerably with varying feedback. Using the Feedback in combination with the Gain control
creates a wide range of tones - thick, bright, lots of color - choose your tone!

PAD - Use Pad to run Gain and Feedback controls near full or increased low end and harmonic

distortion.

THICK - The thick adds a gentle (well maybe not so gentle!) low frequency rise for warmth and
roundness. The eect varies slightly with the load on the pre amp and has a bit of life of its own!

48 VOLT SWITCHING - 48 volt switches phantom power.

PHASE - Reverses the polarity of the pre amp's output.

DI/UNBALANCED IN - This is an unbalanced input for guitar, bass, samples, etc. Simply throw
the toggle switch and you're o. Jack directly into the Class A circuit to provide a tone dierent
than a standard direct box.

Controls and Features

GAIN/GERMANIUM DRIVE - A gain switch in 3dB, is the standard input level type control. The Gain
interacts with the feedback control to oer a variety of tones. Driving this control tends to accent
low frequency and gives a thicker tone.
