Setting Up and Using Your Hartke A
SERIES Combo Bass Amplifier
9. Test the headphone output by turning the Volume con-
trol to its minimum (fully counterclockwise) position and
then connect a standard stereo headphone to the front
panel Phones jack. While playing your bass, slowly turn
the Volume control up—you should hear sound from the
headphones and none from the connected speaker. We
recommend the use of large size headphones (those with
large transducers) for optimum bass reproduction.
10. If you need to connect the A Series to a PA system or
a recording mixing console, connect a cable between the
rear-panel Direct Out output and a Line-level input on the
mixer. (See C on page 6 in this manual for more informa-
tion on the use of the A Series Direct Out).
11. If you’re using a professional external signal processor
that has Line-level inputs and outputs, turn your A Series
amp off momentarily and then connect a standard audio
cable between the rear panel Preamp Out jack and your
effects processor input and another standard audio cable
between the Amp In jack and your effects processor out-
put. (If required, multiple effects processors can be daisy-
chained together, output to input). Then turn the A Series
amp back on and play your bass while adjusting the con-
trols of your effects processor(s). For best results, set both
the input and output gain of the connected effects proces-
sor(s) to 0 dB (unity gain), so that there is no increase or
decrease in level whether the effects are switched in or
out.

using your Hartke A Series Bass Combo Amplifier, you can
