Summary

Introduction to Hartke Bass Amplifiers

Key Features of Hartke 5000/7000

Guided Tour - Front Panel Controls

Passive Input Jack

Connect passive bass guitars to the 1/4" unbalanced jack with high impedance input sensitivity.

Active Input Jack

Connect active bass guitars to the 1/4" unbalanced jack with high impedance input sensitivity.

Pre-Amp A (Tube) Control

Adjusts tube preamplification for classic amplifier sound; avoid maximum settings for distortion.

Pre-Amp B (Solid State) Control

Adjusts solid state preamplification for modern amplifier sound; avoid maximum settings for distortion.

Compression LED Indicator

Indicates compression status: green for off, unlit for 2:1 ratio, red for limiting.

Compression Control

Adjusts compression amount (peak signal reduction) from 2:1 to infinity (limiting).

Graphic Equalizer In/Out Switch

Activates or bypasses the graphic equalizer circuitry for custom equalization curve presets.

Graphic Equalizer Sliders

Ten sliders for boost/attenuation of 10 narrow frequency bands to shape tonal response.

Contour Low Pass Control

Broad-band low frequency equalizer providing 18 dB boost/attenuation at 100 Hz.

Contour High Pass Control

Broad-band high frequency equalizer providing 18 dB boost/attenuation at 10 kHz.

Master Volume Control

Sets the overall output volume of the amplifier for desired sound level.

Crossover Frequency Control

Determines cutoff frequency for bi-amping speaker outputs, from 20 Hz to 2.5 kHz.

Balance Control

Adjusts relative signal levels between Low and High frequency speaker outputs.

Power LED Indicator

Indicates when the Model 5000/7000 is powered on.

Power Switch

Turns the Model 5000/7000 amplifier on or off.

Guided Tour - Rear Panel Connections

Fuse Sled and Voltage Setting

Contains fuse holder and shows selected voltage rating; ensure correct setting before powering.

AC Input Socket

Connect the supplied standard 3-pin 'EEC' plug for AC power connection.

High Frequency Speaker Outputs

Outputs frequencies above crossover setting for smaller speakers in bi-amp mode.

Low Frequency Speaker Outputs

Outputs frequencies below crossover setting for larger speakers in bi-amp mode.

Cooling Fan

Provides vital cooling; ensure it is unobstructed and has access to fresh air.

Effect Send Jack

Sends low impedance signal to outboard effects processors or mixing consoles.

Effect Return Jack

Returns low impedance signal from outboard effects processors.

Bi-Amp Switch

Activates or bypasses crossover circuitry for mono or bi-amp speaker configurations.

Direct Out Post/Pre Switch

Selects routing point for Direct Out signal: before or after EQ and compression.

Direct Out Ground Lift Switch

Engages ground lift to eliminate hum or buzz from the Direct Out signal.

Direct Out XLR Jack

Electronically balanced XLR output for routing signal to mixing consoles or PA systems.
