Guided Tour - VX3500 Front Panel 6. 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”...

Guided Tour - VX 3500 Rear Panel 5. Effect Send jack - Use this 1/4” unbalanced jack to send low impedance (600 ohm) signal from the Model 3500 to a professional outboard effects proces- sor 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 VX3500 SPEAKER OUTPUT MINIMUM IMPEDANCE 4 OHMS INPUT PASSIVE ACTIVE POWER Setting up your Hartke Systems 2000/3500 Bass Amplifier is a simple proce- dure 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 find out how each graphic equalizer slider affects the sound of your particu- lar 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 care- fully to the effect of each.
About Compression ∞ COMPRESSION VX3500 Compression control and LED 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 consider- ably 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 screws. Be careful to ensure that the screws are on the proper thread chase. DO NOT PUSH TEE NUT INTO ENCLOSURE.
