GENERAL OPERATION:
The PA2 is a booster pre-amp that can boost the output of any pickup, active or passive up to 20dB, the equivalent of 10 times normal gain.
It is meant to be used at the output of the guitar just before the output jack. Because of the circuit configuration, high impedance pickups
will have their output impedance converted to low impedance in both switch positions. The PA2 does not change the phase of the pickup.
A few notes about boosting:
The amount of “clean” boost you can get from the PA2 is dependent upon the amount of gain you set on the trimpot and the level of power
supply you have. The usual supply is 9 Volts. If you set the trimpot for maximum boost (20dB) the maximum input is .70 Volts when supplied
with a 9-Volt battery. If you set the trimpot half way up (10dB) the maximum input will be 1.4 Volts input for a “clean” output. By increasing the
power supply to 18 Volts, you can virtually double the “clean” headroom of the PA2.
Boosting beyond the “clean” levels will only “square off” the signal and result in an “overdriven” sound.
As the battery voltage begins to drop from use, the amount of “Clean” headroom will diminish as well. If you want a clean boost, then replace
your battery fairly often, or operate at 18 Volts to maximize headroom. If you don’t care about how clean the signal is, but just want to blow
your mind, don’t worry about the supply voltage until you don’t get the sound you’re looking for then change the battery or... Just... Rock on!
