Guided Tour - Model 3500 Rear Panel
1. Fuse sled - This contains a fuse holder and shows the currently selected
voltage rating for your Model 3500. Make sure the voltage rating is correctly
set before powering up the amplifier! Fuse ratings are 8 amp for 115 vac and
4 amp for 230 vac. For information on how to change the voltage rating, see
Appendix C on page 18.
2. AC input - Connect the supplied standard 3-pin “EEC” plug here.
3. Speaker outputs - Connect any 4, 8, or 16 ohm bass cabinet(s) to these
standard unbalanced 1/4” jacks. WARNING: Because of the high power
levels and low frequency content of the signal generated by the Model
3500, use only appropriately rated speaker cabinets (at least 400 watts at 4
ohms) 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. Fan - The fan provides vital cooling to your Model 3500. 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 3500 is used in a dust-free environment.
