Recently bought a used Peavey tnt 115s. Have been told and read on talkbass that to add to my sound buying a 410 would give a greater dynamic. So I found a hartke 410 on Craigslist. Went to check it out plugged into the low and high outputs. And nothing. zero. Nada. Tested the 410 with the dudes Peavey head. Cabinet works fine. Just nothing out my outputs. Anybody have a clue?


Thanks
Rick

You're talking about the crossover section on the front panel? I'm pretty sure those are preamp level outs, not poweramp level outs. So you shouldn't expect them to work with an extension cabinet. Actually I don't think that amp has an extension cabinet jack.

Here's the way I understand Peavey's Crossover section:
The Crossover section is for Bi-amping. From the Crossover section of your 115, you would need to add a head/cab or another combo. You can then adjust the Frequency knob to a frequency crossover point of the 115 - meaning that the 2nd amp would be used to reproduce the frequencies below that crossover point.

On my TNT130, I did the following:
(Crossover section) "High Out" <-patch cable-> (Patch section) "Pwr Amp" - In
(Crossover section) "Low Out" ---------> Combo Amp Input
(Crossover section) - set Frequency knob to crossover frequency

I don't know if your TNT115 has the same configuration, but I thought I'd let you know how I use it. Someone here with more experience might be able to give you better advice or explain it better.

Good luck.

Ok the thought had not occured to me that it was a preamp out. But guess that makes Denver why it didn't work. Second question though and why I was confused its a 500 watt combo. And the schematic on back says 160 watt to the 15. So can someone explain where the lost watts are ? Guess I am proving I am a gear rookie......

OK dead post revival! i have the same 96 Peavey TNT 115s.

is it possible to add a 2x10 combo amp to the crossover high output of the Peavey? so that high frequencies will go to the 2X10 and low frequencies remain at the 15" sheffield speaker of the peavey?

will it be neccessary to connect the crossover low output to the power amp in with a patch cable so that the lows remain to the amp?

And will all this procedure result in higher volume level or at least better sound?

:confused:

Despite the fact that most people seem to use them the way you describe, what Peavey suggests is using a sub + the combo - high out to pwr amp in (on the combo) low out to a separate power amp and sub. A bit of playing around with WinISD reveals the logic to that. The cabs are speaker-x-max limited below 150 hz or so, so shunting that to a sub means you can wind up to the full power of the amp without blowing the speaker, and you can have a very powerful sub amp driving a very powerful sub to fulfill your volume desires. Using the combo for the bottom means you are smack in the range where speaker X-max is the limiting factor and you can't even use the full power of the amp without farting out (exceeding the X-max of) the speaker. WinISD + the box you have + the speaker you have can be very revealing, if you let it.

For your described method, you would use low out to pwr amp in, and high out to a combo amp with 2x10.

You do need a separate (short) cable to the power amp input for either method, since if nothing is plugged into the power amp input it gets the full, non-crossed over signal from the preamp.

Try it and see what you think, if you already own the parts. If you want a better chance of success and don't own all the parts, buy a sub, not a 2x10 combo (IMHO.)

Thank you so much for your analysis. I do not know much of amps cabs ratings etc, but i wanted something with more volume and maybe better sound. Since financially i cannot afford a louder rig (i even not know what is the cheapest solution that is louder than peavey tnt 115s) and where i live is not possible to try any equipment i thought of taking advantage of peavey's crossover function.

So as you have understood i do not own another combo. I was trying to collect information about the situation first and then buy the appropriate equiment which i suppose it is a lot cheaper than buying a whole new rig....:what:

I also i am in possession of a custom cab that i made with a tweeter and a 12" electrovoice speaker from sx300 that was full range (destroyed) and repaired by a tech for use with bass. As a power amp i could use a yamaha jx50b head that was dettached from a yamaha jx50b combo. :o let's see what happens....

Guys up above ^^^ are correct. You need a patch cable (1' or 2' instrument cable) to run from either LOW OUT or HIGH OUT into the POWER AMP IN on your amp. I have seen guys run simple an instrument cable from HIGH/LOW OUT into a different amp and not use the patch cable on the Peavey, thinking that all was well. But, if you skip the patch cable part on the Peavey, you are still getting full range in that combo - not bi-amped. I dunno if the newer models will even allow that anymore - it's possible that when you plug into HIGH/LOW OUT that it might cut the power at that point, forcing you to use a patch cable. I have also heard (in person - not "read about") good results from using the combo to bi-amp. One guy I knew used the old Combo 300 for lows and a TNT or TKO (don't remember which) on top for highs. Unusual, but it rocked. lol Just don't skip that patch cable on the Peavey. And, experiment with it.

One of the problems with bi-amping is that it is completely misunderstood by many. The thought that a 15" will have more low end than a 2x10" is wrong. it entirely depends on each cabinet design. For mids and highs a single 6" or 8" driver is all that's needed.

Will the system be louder? Probably not. In full range all frequencies are passed to the cabinets. In bi-amp, lows go to one cabinet and highs to another. It takes twice the power, assuming a stereo power amp is used, to get the signal out to the audience.

I was thinking more of a 2x10 combo or amp+cab. I constantly keep running the Peavey gain at 6 and volume at 7 and i an afraid that it will not stand the abuse much longer plus it is harsh sounding at such volumes no matter what bass or eq settings i use. That is why i was looking to add a second amp without having to spent a fortune on a new rig.

Will it be louder? Yes. Right now you have one combo amp (1x15) and you are looking at adding a second cab and amp (4x10). Whether you bi-amp it or not, it will be much louder.

Sorry but this is incorrect. If the volumes of the individual amps are set properly the total will be the same as a full range cabinet, just using two amps instead of one. Mixing a 4x10 and a 1x15, bi-amp or no, is a recipe for blown drivers.
