5. Fan - The fan provides vital cooling to your Model 5000/7000 . Make sure
that it is kept free of all obstructions and that cool, fresh air is accessible at all
times. Also, try to ensure that the Model 5000/7000 is used in a dust-free
environment.
6. Effect Send jack - Use this 1/4" unbalanced jack to send low impedance
(600 ohm) signal 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. You can also use the Effect Send jack to route sig-
nal to an external mixing console or amplifier with an input sensitivity of +4 dB.
7. Effect Return jack - Use this 1/4" unbalanced jack to return low impedance
(600 ohm) signal from a professional outboard effects processor.*
8. Bi-Amp switch - When out (the "On" position), the crossover circuitry is
active and the top two speaker output jacks (labeled "High Frequency") send
only frequencies above the Crossover Frequency setting, while the bottom two
speaker output jacks (labeled "Low Frequency") send only frequencies below the
Crossover Frequency setting (for more information, see page 4). When pressed
in (the "Mono" position), the crossover circuitry is disabled and full range audio is
sent to all four speaker outputs.
9. Direct Out Post/Pre switch - When pressed in (the "Pre" position), signal is
routed to the Direct Out jack prior to the 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.
10. Direct Out Normal/Ground Lift switch - When pressed in (the "Gnd. Lift"
position), 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.
11. Direct Out jack - Use this electronically balanced XLR jack to route signal
from the Model 5000/7000 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 (600 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.
