The Hartke Systems Model 5000 Bass Amplifier offers all the newest concepts in bass amplification.
Features
Two independent amplifiers within each chassis, with power to spare - a full 250 watts (into 4 ohms).
Hartke's unique Transient Attack¬ circuitry ensures that every nuance of your bass performance is reproduced faithfully.
Two Pre Amp input knobs allow custom blending of tube and solid state sounds.
Ten bands of high-quality graphic equalization allow 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.
LEDs show you the settings of the graphic equalizer in low-light environments, and a 2-color LED continuously shows the status of the compression circuitry in response to your playing. Two fully adjustable contour knobs (high pass and low pass) provide further control over shaping your bass sound.
A built-in compressor not only adds real "punch" to your bass sound, but also allows you to smooth out volume differences between notes.
Two independent inputs accommodate both passive and active bass guitars.
Protection relay circuitry protects connected speakers from dangerous overloading, and prevents "thumps" when powering on or off.
Two pairs of dedicated speaker outputs (one for high frequency speakers and the other for low frequency speakers), along with front-panel Crossover Frequency and Balance controls.
A Bi-Amp switch enables you to activate or bypass the electronic crossover circuitry.
Effects loop send and return jacks allow you to connect to professional outboard effects processors.
An electronically balanced direct output provides a means of routing signal to professional mixing consoles in both live performance 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.
Rugged construction makes the Model 5000 eminently roadworthy.
