Features

The Hartke Systems Model 2000/3500 Bass Amplifiers offer all the newest

concepts in bass amplification. Here are some of their main features:

• Power to spare—in the case of the Model 2000, 200 watts into 4 ohms, and,

in the case of the Model 3500, a full 350 watts into 4 ohms.

• Our unique Transient Attack® circuitry which 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 but-

ton 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.

• In the Model 3500, 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.

• In the Model 3500, an electronically balanced direct output that provides a

means of routing signal to professional mixing consoles in both live perfor-

mance and recording environments. A ground loop switch helps prevent

hum or buzz from entering the signal, and a pre/post switch allows the direct

signal to be derived either before or after the amp EQ section.

• In the Model 3500, LEDs that show you the settings of the graphic equalizer

in low-light environments as well as a two-color LED that continuously

shows the status of the compression circuitry in response to your playing.

• In the Model 2000, a high pass filter on/off switch that enables connected

speakers to be protected from subsonic frequency input.

• Rugged construction makes both the Model 2000 and Model 3500 eminently

road-worthy.
