7. Graphic Equalizer In/Out switch - When pressed in (the "In" position), the Model 5000/
7000's graphic equalizer circuitry (as described in #8 below) is operational. When pressed out
(the "Out" position), it is bypassed. The provision of this switch allows you to set up a custom
equalization curve (an equalization "preset") with the graphic EQ sliders, which can then be
activated with the press of a single button.
8. Graphic Equalizer - These sliders allow you to "draw" the tonal response of the system by
adding 15 dB of boost or attenuation to ten different narrow-band frequency 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 5000/7000. When a slider is at its center detented ("0") position, the selected fre-
quency area is unaffected (it is said to be flat). When a slider is moved up (above the "0" posi-
tion, 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 attenuat-
ed. For more information, see the "About Equalization" section on pages 9 - 10 of this manual.
9. Contour Low Pass control - This acts as a broad-band low frequency equalizer, providing
18 dB of boost or attenuation at 100 Hz. You should generally adjust this control (and the
Contour High Pass control, described in #10 below) prior to "fine-tuning" the system with the
graphic equalizer (as described in #8 above). For more information, see the "About Equalization"
section on pages 9 - 10 of this manual.
10. Contour High Pass control - This acts as a broad-band high frequency equalizer, providing
18 dB of boost or attenuation at 10 kHz. You should generally adjust this control (and the
Contour Low Pass control, described in #9 above) prior to "fine-tuning" the system with the
graphic equalizer (as described in #8 above). For more information, see the "About Equalization"
section on pages 9 - 10 of this manual.
11. Master Volume control - This is the overall volume control. For best signal-to-noise ratio,
keep the output of your bass at or near maximum and adjust the amp's Master Volume to the
desired level.
12. Crossover Frequency control - The Model 5000/7000 actually contains two discrete ampli-
fiers. When the rear-panel Bi-Amp switch (see page 6) is in the "On" position, the Crossover
Frequency control is active. When the rear-panel Bi-Amp switch is in the "Mono" position, the
Crossover Frequency control has no function. When active, this control determines the "cutoff"
points for the High/Low Frequency speaker output pairs (see page 5) as follows: only frequen-
cies below the cutoff value are output from the Low Frequency speaker jacks, while only frequen-
cies above the cutoff value are output from the High Frequency speaker jacks. For example, if
you set the Cutoff Frequency to 500 Hz (the 12 o'clock position), frequencies from 20 Hz (the
lowest possible frequency you can hear) to 500 Hz are output from the Low Frequency speaker
jacks, while frequencies of 500 Hz and higher are output from the High Frequency speaker jacks.
The maximum setting of the Crossover Frequency control (fully clockwise) is 2.5 kHz. This maxi-
mum setting is particularly useful when connecting the High speaker jacks to small diameter
speakers such as tweeter arrays.
13. Balance control - Located in the Crossover section of the front panel, this control deter-
mines the relative signal levels output to the Low and High speaker jacks. When set at the
center detented "0" position, equal signal levels are routed to both pairs of speaker outputs.
14. Power LED - Lights whenever the Model 5000/7000 is powered on.
15. Power switch - Use this to power the Model 5000/7000 on or off.
