GENERAL OPERATION:
The EMG-AB is a booster pre-amp that uses a Push-Pull Pot to activate the amount of boost you want. When the Push-Pull pot is in the "down"
position there is no boost and the control has no effect. In the "up" position, rotating the pot can boost the input by up to 20dB at full rotation.
Both passive and active pickups can be used with the EMG-AB. The AB is designed to be placed last in the signal chain just before the output jack.
Also, the AB will convert a guitar with passive (High Impedance) pickups to a low impedance output.
A few notes about boosting:
The amount of "clean" boost you can get from the AB is dependent upon the amount of gain you set on the pot and the level of power
supply you have. The usual supply is 9 Volts. If you turn the pot for maximum boost (20dB) the maximum input is .70 Volts for a clean output
when supplied with a 9 Volt battery. If you turn the pot 1/2 way (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 AB.
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!
IMPORTANT INSTALLATION NOTES:
Only one 9-Volt battery is required to power the pickups and any accessories such as the AB, SPC, EXG or other EMG Controls.
Use an Alkaline or Lithium battery for longest life. If your installation is different from the diagrams in these instructions or you need additional
diagrams visit our website: emgpickups.com for a complete listing of available diagrams.
