Introduction Congratulations on purchasing the Hartke VX2510 & VX2515 Bass Amplifier! Although this unit is 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. The VX2510 & VX2515 combos feature tH HA2500 amplifer providing 250 watts of power to the built-in 2-way bass speaker system.
Features The Hartke VX2510 & VX2515 bass amplifier offers all the newest concepts in bass amplification. Here are some of its main features: • Power to spare — The VX2510 & VX2515, a full 250 watts delivered to its internal 4 ohm speaker system. • Internal, 2-way bass speaker system including two custom design 10-inch low frequency drivers, plus 1-inch high frequency compression driver in the VX2510 and custom design 15-inch low frequency drivers, plus 1-inch high frequency compression driver in the VX2515.
Guided Tour - VX2510 & VX2515 Front Panel 1 4 HA2500 2 1. Passive Input jack - If your bass guitar has passive circuitry, connect it to the Model 2500 here. This standard, 1/4” unbalanced jack provides a high impedance (100 k Ohms) input sensitivity of 20 millivolts. 2. Active Input jack - If your bass guitar has active circuitry,* connect it to the Model 2500 here.
Guided Tour - VX2510 & VX2515 Front Panel 5. Compression control - This determines the amount of compression (peak signal reduction) by simultaneously adjusting both threshold and compression ratio (which ranges from 2:1 to infinity [limiting]). At the fully counterclockwise “Off” position, the circuitry is bypassed and no compression is applied (the knob clicks when set to the “Off” position). As the knob is raised clockwise (at settings from “1” to “∞”) increasing amounts of compression are applied.
Guided Tour - VX2510 & VX2515 Rear Panel 1 3 5 4 6 2 1. Fuse sled - This contains a fuse holder and shows the currently selected voltage rating for your Model 2500. Make sure the voltage rating is correctly set before powering up the amplifier! Fuse ratings are 10 amp for 115 vac and 6.2 amp for 230 vac. For information on how to change the voltage rating, see Appendix B on page 14. 2. AC input - Connect the supplied standard 3-pin “IEC” plug here. 3.
Guided Tour - VX 2500 Rear Panel 5. Effect Send jack - Use this 1/4” unbalanced jack to send low impedance (100 ohm) signal from the Model 2500 to a professional outboard effects processor such as a reverb, echo, chorus, flanger, or harmonizer device.* Output level is approximately 0 dB to +4 dB and is post-EQ and post-compression but unaffected by the setting of the Master Volume control.
Setting Up and Using the VX2510 & VX2515 Setting up your Hartke Systems VX2515/VX2510 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. 2.
Setting Up and Using The VX2510 & VX2515 7. Experiment with altering the balance of the two Pre-Amp knobs, listening to the effect each has on the overall sound. Depending upon the specific instrument you are using and your personal taste, you may prefer the sound of one over the other, or you may prefer a particular blend of the two. Note that, when both are used at equal settings, the amplifier will be twice as loud as when only one is used.
About Equalization The Hartke Systems Model 2500 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.
Appendix A: CASTER INSTALLATION • Locate one caster and four each of the supplied screws and lock washers. • Hold the caster in place and hand start the screws. Be careful to ensure that the screws are on the proper thread chase. DO NOT PUSH TEE NUT INTO ENCLOSURE. • Use a screw driver to tighten the four screws. Be careful not to over tighten the screws. • Repeat the steps above for the remaining three casters.
