Guided Tour - 3500/5500 Rear Panel
6. Effect Return jack - Use this 1/4" unbalanced jack to return low impedance
(600 ohm) signal to the Model 3500/5500 from a professional outboard effects
processor.*
7. Balance control - Use this to adjust the relative amount of Effect Send (dry)
versus Effect Return (wet) signal being routed to the Model 3500/5500 speaker
outputs. At the center-detented "0" position, equal amounts of Send and Return
signal are routed. At its fully counterclockwise ("Send") position, no signal from a
connected effects processor(s) is added to the main output. At its fully clockwise
("Return") position, the only signal you hear is that coming from a connected out-
board effects processor(s). If your outboard effects processor has an adjustable
wet/dry control, we recommend that you set the Balance knob to its fully clock-
wise ("Return") position and use the effects processor's wet/dry control to adjust
the relative mix. Alternatively, you can set the effects processor to output fully
"wet" signal and use the Model 3500/5500 Balance knob to adjust the relative
mix of dry vs. wet signal
8. Direct Out Post/Pre switch - When pressed in (the "Pre" position), signal is
routed to the Direct Out jack prior to the Model 3500/5500 ten-band graphic
equalizer (but after the compression circuitry and Contour controls). When out
(the "Post" position), signal is routed to the Direct Out jack after all compression
and EQ circuitry (both ten-band graphic and Contour).** Use the "Pre" position
when you want the console engineer to have control over equalizing your bass
signal; use the "Post" position when you want to use the front panel ten-band
graphic equalizer to equalize your bass signal before sending it to the console.
9. Direct Out Normal/Ground Lift switch - When pressed in (the "Gnd. Lift" posi-
tion), pin 1 is removed from the chassis. This should be used only when a ground
loop hum or buzz is heard; otherwise, leave it in the out ("Normal") position.
10. Direct Out jack - Use this electronically balanced XLR jack to route signal
from the Model 3500/5500 to a professional mixing console or as a tap to a main
PA system via a mic input on the console. The signal output from this jack is low
impedance (100 ohm) with an output level of approximately -30 to -20 dB. You
can also use the Direct Out jack to route signal to an external amplifier with a -10
dB input sensitivity.
* In-line effects (such as footpedals) intended for low signal levels should be placed
between the bass and the amplifier Input and not connected with the Effect Send and
Return jacks.
** Note that the settings of the ten-band graphic equalizer will affect a "Post" Direct
Out signal regardless of the position of the front panel In/Out switch.
