Congratulations on purchasing the Hartke HA5500 Bass Amplifier! Although this
unit is designed for easy operation, we suggest you first take some time to go
through these pages so you can fully understand how we’ve implemented a
number of unique features.
The HA5500 provides 500 watts of power to a 4 ohm speaker system or 350
watts to an 8 ohm speaker system. With that kind of power, the HA5500 is
EXTREMELY loud and punchy. In addition, the HA5500 offers a number of
additional advanced features, including front-panel compression and graphic
equalizer LED indicators, effects send and return jacks, an effects send/return
balance knob, and a direct output with ground lift and pre or post EQ selection.
The HA5500 is optimized for use with electric bass instruments, and the front
panel controls in both models are virtually identical. You’ll find either to be an
excellent bass amplifier for live performance use in small and medium-size ven-
ues; in addition, the HA5500’s advanced pre-amp features makes it ideal for
use in recording environments.
In these pages, you’ll find a detailed description of the many features of the
HA5500 bass amplifier, as well as a guided tour through their front and rear
panels, step-by-step instructions for setting up and using each product, detailed
discussions about equalization and compression, and 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 these and other Hartke and Samson products in the future.
