5Guided Tour - VX3500 Front Panel6. Compression control - This determines the amount of compression (peaksignal reduction) by simultaneously adjusting both threshold and compressionratio (which ranges from 2:1 to infinity [limiting]). At the fully counterclockwise“Off” position, the circuitry is bypassed and no compression is applied (the knobclicks when set to the “Off” position). As the knob is raised clockwise (at set-tings from “1” to “∞”) increasing amounts of compression are applied. For moreinformation, see the “About Compression” section on page 15 of this manual.7. Graphic Equalizer In/Out switch - When pressed in (the “In” position), theModel 3500’s graphic equalizer circuitry (as described in #8 below) isoperational. When pressed out (the “Out” position), it is bypassed. Theprovision of this switch allows you to set up a custom equalization curve (anequalization “preset”) with the graphic EQ sliders, which can then be activatedwith the press of a single button.8. Graphic Equalizer - These sliders allow you to “draw” the tonal response ofthe system by adding 15 dB of boost or attenuation to ten different narrow-bandfrequency areas (30 Hz, 64 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 3 kHz,5 kHz, and 8 kHz), affecting the main output signal of the Model 3500. When aslider is at its center detented (“0”) position, the selected frequency area isunaffected (it is said to be flat). When a slider is moved up (above the “0”position, towards the “+15” position), the selected frequency area is boosted,and when it is moved down (below the “0” position, towards the “-15” position),the selected frequency area is attenuated. For more information, see the “AboutEqualization” section on pages 13 - 14 of this manual.9. Contour Low Pass control - This acts as a broad-band low frequencyequalizer, providing 18 dB of boost or attenuation at 100 Hz. You shouldgenerally adjust this control (and the Contour High Pass control, described in#10 below) prior to “fine-tuning” the system with the graphic equalizer (asdescribed in #8 above). For more information, see the “About Equalization”section on pages 13 - 14 of this manual.10. Contour High Pass control - This acts as a broad-band high frequencyequalizer, providing 18 dB of boost or attenuation at 10 kHz. You shouldgenerally adjust this control (and the Contour Low Pass control, described in #9above) prior to “fine-tuning” the system with the graphic equalizer (as describedin #8 above). For more information, see the “About Equalization” section onpages 13 - 14 of this manual.11. Master Volume control - This is the overall volume control. For bestsignal-to-noise ratio, keep the output of your bass at or near maximum andadjust the amp’s Master Volume to the desired level.12. Power LED - Lights whenever the Model 3500 is powered on.13. Power switch - Use this to power the Model 3500 on or off.
