Guided Tour - Rear Panel
1. Fuse sled - This contains a fuse holder and shows the currently selected
voltage rating for your Model 5000/7000. Make sure the voltage rating is cor-
rectly set before powering up the amplifier! Fuse ratings for the Model 5000
are: 15 amp for 115 VAC and 8 amp for 230 VAC. Fuse ratings for the Model
7000 are: 20 amp for 115 VAC and 10 amp for 230 VAC. For information on
how to change the voltage rating, see Appendix C on page 14.
2. AC input - Connect the supplied standard 3-pin “EEC” plug here.
3. High Frequency speaker outputs - When the rear-panel Bi-Amp switch
(see page 6) is set to the “On” position, only frequencies above the front-panel
Crossover Frequency setting (see page 4) are output from these standard unbal-
anced 1/4” jacks. In this case, medium or small diameter speakers (such as
tweeter arrays) should be connected to these jacks. When the rear-panel Bi-
Amp switch is set to the “Mono” position, full range audio is output from these
jacks as well as from the Low Frequency speaker outputs (see #4 below).
WARNING: Because of the high power levels and low frequency content
of the signal generated by the Model 5000/7000, use only appropriately
rated speaker cabinets (see Appendix A on page 12) that are specifically
designed for bass instruments. We recommend that Hartke amplifiers be
used with Hartke bass cabinets, although other brands of speakers can be used.
4. Low Frequency speaker outputs - When the rear-panel Bi-Amp switch (see
page 6) is set to the “On” position, only frequencies below the front-panel
Crossover Frequency setting (see page 4) are output from these standard unbal-
anced 1/4” jacks. In this case, large diameter speakers (such as subwoofers)
should be connected to these jacks. When the rear-panel Bi-Amp switch is set
to the “Mono” position, full range audio is output from these jacks as well as from
the High Frequency speaker outputs (see #3 above).
WARNING: Because of
the high power levels and low frequency content of the signal generated
by the Model 5000/7000, use only appropriately rated speaker cabinets
(see Appendix A on page 12) that are specifically designed for bass instru-
ments.
We recommend that Hartke amplifiers be used with Hartke bass cabi-
nets, although other brands of speakers can be used.
