Introduction
We know you don’t like reading owners manuals, but you’ve just purchased one of the
finest bass amplifiers around, and we want to tell you about it! So, before you plug in and
start popping and slapping, we’d like to suggest you take just a few moments out to scan
these pages. We’ll make it as painless as possible, we promise—and, who knows, you
might just pick up a tip or two.
The A25 and A35 are powerful combo amplifiers, which include a matched 8-ohm alu-
minum bass speaker in a specially designed cabinet which can be used either flat on the
floor or on its “kickback” position for increased high end clarity on directionality. They’re
the perfect system for use in small venues such as club dates and for home recording stu-
dios. Plus, the CD input and dedicated headphone output makes them awesome practice
amps!
There are four different models in the A Series, and this manual covers the A25 and A 35.
The A25 is the most compact in the family; it's got a 25-watt amp and an 8" custom design
Hartke Aluminum Series speaker. The A35 has a 35-watt amp and a 10" custom design
Hartke Aluminum Series speaker. Whichever of these models you’ve purchased, you’re
assured of that great Hartke sound and robust construction.
In these pages, you’ll find a detailed description of the many features of your A Series
Combo Bass Amplifier, as well as a guided tour through its front and rear panels, step-by-
step instructions for setting up and using the amp, additional information about equaliza-
tion, plus full specifications. You’ll also find a warranty card enclosed—please don’t forget
to fill it out and mail it so that you can receive online technical support and so we can send
you updated information about this and other Hartke and Samson products in the future.
