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 A70 and A100 are powerful combo amplifiers, which include a matched 8 ohm aluminum 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 studios. 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 A70 and A100. The A70 is a compact combo with a 70 watt amp and an 12 inch custom designed Hartke Aluminum Series speaker. The A100 has a 100 watt amp and a 15 inch custom designed 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-bystep instructions for setting up and using the amp, additional information about equalization, 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. Also, be sure to check out our website (http://www.samsontech.com) for complete information about our full product line.

Combo Bass Amplifier Features

The Hartke A Series offers all the newest concepts in state-of-the-art aluminum drive bass amplification in an extremely compact size and affordable price. Here are some of its main features:

• The A70 delivers 70 Watts of power to its specially designed 12 inch aluminum

bass driver, while the A100 delivers 100 Watts to its specially designed 15 inch aluminum bass driver.

• Specially designed cabinet which can be used either flat on the floor or on its

“kickback” position for increased high end clarity.

• Bipolar circuit design ensures that every nuance of your bass performance is

reproduced faithfully.

• Flexible inputs that accommodate a broad range of input levels, so that you can

use the A Series with pretty much any kind of bass, from passive models to those with active circuitry. It is almost impossible to overload the input of an A Series bass amplifier!

• Bass and Treble plus a high-quality seven band Graphic Equalizer, allow you to

create a broad range of tonal colors for your bass instrument.

• Line-level effects loop send (Preamp Out) and return (Amp In) jacks that allow

you to connect to professional outboard effects processors.

•A dedicated CD input is included allowing you to hook up a portable CD or MP3

player to practice along with.

•A separate headphone output, which automatically disconnects the speaker out-

put, allowing use as a high-quality practice amp.

• For interfacing with PA systems or recording mixing consoles, an XLR line-level

direct output is included on the rear panel.

• Included is a matched Hartke 8 ohm speaker mounted in a specially designed

cabinet for clean, crisp sound.

• Rugged construction makes the A Series eminently road-worthy.
