Hartke 5000 Transient Attack?

[four/five]

Those that may not be familiar with this amp, here’s a rough guide.

It consists of two 250w amps which drive two separate cabs. The amp can also be put in a biamp mode,with one amp driving lower frequencies into a cab and the other amp driving higher frequencies into separate cab.

Does anyone know if just one channel amp can be used to drive one cab only. The other channel not being connected to any cab. Thus saving having to lug two cabs about?

The amps can’t be “bridged” or you get “magic smoke” .

Hartke don’t seem as contactable as they were years ago.

Here's a link to the Hartke 5000 manual - http://www.samsontech.com/site_media/legacy_docs/5000_7000_manual.pdf

On page 9 under 'Setting Up' (para 2) it says:

"If you are only using a single bass cabinet or multiple cabinets with the same diameter speakers, place the switch in the “Mono” position and connect the cabinet(s) to any of the four 1/4” unbalanced Speaker output connectors on the rear panel."

As long as the cab is rated at 4 ohms or higher it looks like one cab will be fine.

Thank you for the reply. I thought you could do this but always a bit wary of leaving an output “open” with no load. Did toy with putting a wire wound resistor 8ohms across the connection in a separate box. Perhaps the “unused” part of the amp shuts down if a speaker is not in circuit. For a 250w amp in single channel mode it can certainly get loud.

It's not a power tube amp : these need a load connected, not transistor power amp.

Although rare, there are ss amps that love load and tube amps that survive by themselves. So I would say that without consulting the manual, the load equals better safe than sorry.
