Pre-Champ Versatile Preamplifier Kit Expansion Modules 5mm Audio Out 1x HDMIAssembly Required Refer Silicon Chip July 1994 This tiny preamp was specifically designed to be used with the Champ amplifier KC 5152. Unless you have a signal of sufficient amplitude the Champ will not produce its maximum power output. The Pre Champ is the answer with a gain in excess of 40dB, which is more than enough for most applications. You can vary the gain by changing a resistor and theres even provision on the PCB for an electret microphone.
