Features - Hartke HA3500 Owner's Manual

The Hartke Model 3500/5500 bass amplifier offers all the newest concepts in
bass amplification. Here are some of its main features:
• Power to spare — The Model 5500, a full 500 watts delivered to a 4 ohm
speaker system or 350 watts to an 8 ohm speaker system. The model 3500
delivers 350 watts to a 4 ohm speaker or 240 watts to a 8 ohm speaker.
• Our unique Transient Attack® circuitry ensures that every nuance of your
bass performance is reproduced faithfully.
• Two Pre-Amp input knobs, allowing custom blending of tube and solid state
sounds.
• Ten bands of high-quality graphic equalization, allowing you to create a
broad range of tonal colors for your bass instrument. A dedicated in/out
button allows you to preset an equalization curve.
• Two fully adjustable contour knobs (high pass and low pass), which provide
further control over shaping your bass sound.
• A built-in compressor which not only adds real "punch" to your bass sound,
but also allows you to smooth out volume differences between notes.
• Two independent inputs that accommodate both passive and active bass
guitars.
• Protection relay circuitry that protects connected speakers from dangerous
overloading and also prevents "thumps" when powering on or off.
• Effect loop send and return jacks that allow you to connect to professional
outboard effects processors.
• An effect Balance knob which enables you to adjust the relative amount of
Send ("dry") versus Return ("wet") effect signal being routed to the speaker
outputs.
• Electronically balanced direct output that provides a means of routing sig-
nal to professional mixing consoles in both live performance and recording
environments. A ground lift switch helps prevent hum or buzz from enter-
ing the signal, and a pre/post switch allows the direct signal to be derived
either before or after the amp EQ section.
• LEDs that show you the settings of the graphic equalizer in low-light envi-
ronments as well as a two-color LED that continuously shows the status of
the compression circuitry in response to your playing.
• Rugged construction makes the Model 3500/5500 eminently road-worthy.
