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.
8. Next, experiment with altering the balance of the two Pre-Amp knobs, listen-
ing 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. In step #4 above, we recommended that you begin with both
knobs at their midway "5" setting, but the two Pre-Amp knobs can in fact be set
to any blend you like. However, avoid setting both to their maximum "10" posi-
tion since this setting will almost always result in undesirable distortion.
9. When you have settled on a Pre-Amp balance, the next step is to adjust the
two Contour (bass and treble equalizer) controls to taste. For more information,
see the "About Equalization" section on page 9 of this manual. When you get a
great setting that complements your instrument and playing style, it's a good
idea to write it down for future use.
10. Next, experiment with the graphic equalizer. Begin by setting each of the
ten sliders to their flat "0" center detented position. Then press in the In/Out
switch (to its "In" position) so that the graphic equalizer is activated. Finally,
move each slider in turn as you play your bass. For more information, see the
"About Equalization" section on page 9 of this manual. Again, when you get a
graphic equalization setting that complements your instrument and playing style,
it's a good idea to write it down for future use.
11. Then try out the compression circuitry. Activate it by turning the
Compression knob clockwise from its "Off" position (you'll hear a click when it is
activated). As you turn the knob clockwise, the input signal from your bass
becomes more and more severely compressed—you'll hear peak signals (such
as string slaps and pulls) begin to sound increasingly "squashed," relative to the
lower-level signals produced by standard playing. The result will be a decreased
dynamic range but an overall leveling of signal throughout the full pitch range of
your instrument. For more information, see page 11. The Compression LED will
light steadily green when no compression is being applied, will go out whenever
small amounts of compression are being applied and will flash or light steadily
red when limiting (severe compression) is being applied.
12. If you're using an external signal processor, turn the amplifier off momentari-
ly and then connect a standard audio cable between the Effect Send jack and
your effects processor input and another standard audio cable between the
Effect Return jack and your effects processor output (if required, multiple effects
processors can be daisy-chained together, output to input). Then turn the Model
5000/7000 back on and play your bass while adjusting the controls of your
effects processor(s). For best results, set both the input and output gain of all
connected effects processor(s) to 0 dB (unity gain), so that there is no increase
or decrease in level whether the effects are switched in or out.
If you have followed all the steps above and are still experiencing difficulties, call
Samson Technical Support (516-932-1062) between 9 AM and 5 PM EST.
