Introduction Congratulations on purchasing the Hartke Systems Model 5000 /7000 Bass Amplifier! Although these units are 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.
Features The Hartke Systems Model 5000/7000 Bass Amplifiers offer all the newest concepts in bass amplification. Here are some of their main features: • Two independent amplifiers within each chassis, with power to spare—in the case of the Model 5000, 250 watts per channel (into 4 ohms), and, in the case of the Model 7000, a full 350 watts (into 4 ohms). • Our unique Transient Attack® circuitry which ensures that every nuance of your bass performance is reproduced faithfully.

Guided Tour - Front Panel 7. Graphic Equalizer In/Out switch - When pressed in (the “In” position), the Model 5000/ 7000’s graphic equalizer circuitry (as described in #8 below) is operational. When pressed out (the “Out” position), it is bypassed. The provision of this switch allows you to set up a custom equalization curve (an equalization “preset”) with the graphic EQ sliders, which can then be activated with the press of a single button. 8.

Guided Tour - Rear Panel 5. Fan - The fan provides vital cooling to your Model 5000/7000 . Make sure that it is kept free of all obstructions and that cool, fresh air is accessible at all times. Also, try to ensure that the Model 5000/7000 is used in a dust-free environment. 6. Effect Send jack - Use this 1/4” unbalanced jack to send low impedance (600 ohm) signal to a professional outboard effects processor such as a reverb, echo, chorus, flanger, or harmonizer device.
Setting Up and Using the Model 5000/7000 Setting up your Hartke Systems 5000/7000 Bass Amplifier is a simple procedure which takes only a few minutes: 1. Remove all packing materials (save them in case of need for future service) and decide where the amplifier is to be physically placed. To avoid potential overheating problems, be sure that the rear panel is unobstructed and that there is good ventilation around the entire unit, particularly behind the rear-panel fan.
Setting Up and Using The Model 5000/7000 7. If you are using the Model 5000/7000 in Bi-Amped mode (that is, if you have set the rear-panel Bi-Amp switch to “On” and are using two or more cabinets with different diameter speakers), experiment with the Crossover Frequency and Balance controls until you achieve the desired blend. When connecting very small diameter speakers (such as tweeter arrays) to the High Frequency speaker outputs, set the Crossover Frequency to its fully clockwise position.
About Equalization The Hartke Systems Model 5000/7000 Bass Amplifier gives you enormous control over shaping the sound of your bass, using a process called equalization. To understand how this works, it’s important to know that every naturally occurring sound consists of a broad range of pitches, or frequencies, combined together in a unique way. This blend is what gives every sound its distinctive tonal color.
About Equalization To find out how each graphic equalizer slider affects the sound of your particular bass, start with all ten bands flat (that is, all ten sliders at their detented “0” center position). Then, one by one, raise and lower each slider, listening carefully to the effect of each. If you don’t specifically need to utilize the ten-band graphic equalizer, bypass it by setting the In/Out switch to its “Out” position.
About Compression The dynamic range of a sound is the difference between its loudest and softest points. For example, as you play your bass, you’ll probably find that some notes (for example, notes played on the upper frets of the lowest string) are considerably louder than others.
