WITHDRAWN

I have a peavey tmax rackmount head which although extremely heavy sounds great with two of the new compact Trace Elliot 1518c cabinets.

I also have an old 2 x 10 and am thinking of BiAmping which is something the T max is set up to do. My questions are purely techical

1 Are the outputs from the crossover low or crossover high at line level and therefore need further amplification or are they powerd speaker outputs which will drive a speaker cabinet

2 When you plug into the crossover outputs will the normal speaker outs be disabled

3 I also have a peavey BH 500 powered 2 x 10 top box If I wish to use this what output on the amp would I use. If I use the line out would the t max still drive the 2 1 x15s ok


cheers skez

I used to own a Tmax but never really got to grips with the Bi-amping feature. I can tell you though that you will need a seperate power amp to use it. My best guess is that you feed one of the crossover outputs into the Pwr amp in, which gives you half of the Bi-amped signal out of the speaker output on the Tmax, and the other crossover output goes to a seperate power amp.

I don't know why they don't cover this in the owners manual

[Skezza]

So you would be just using the tmax as a preamp

No, the power amp of the Tmax would be providing half of your bi-amped high level output. I assume the "Pwr amp in" jack drives the power amp and gives an output on your speaker jacks. The external power amp, driven by the other crossover output, provides the other half.

[Skezza]

If I went into the pwr amp in what would i go froma separate preamp I just don not get it

can you explain in a little more detail

Actuall Ive just got what you meean Ill try it

Confused? I certainly am I've never actually done this so it'd be useful if someone who had would chip in but bi-amping seems to be something not many people do.

To put it slightly differently to help your understanding, looking at the back panel layout, there are two bi-amp outputs. One is for your high frequencies, one is for low frequencies. They are both line level so each of these outputs needs to drive it's own power amp and each power amp drives a speaker.

So you need 2 separate power amps to bi-amp. One of these will be the internal power amp in the Tmax which you drive by looping the first crossover output into the "Pwr amp in" jack on the back of the Tmax and that will drive a speaker via the normal speaker jacks on the back of the amp.

The second crossover output goes to your external power amp and then to another speaker. Then you'll have hours of fun messing around with the crossover frequency point and the balance control

I'll be interested to know how you get on, whether it sounds pants or like the voice of God speaking through your Trace Elliots

Edit: How the pre on the Tmax works is a whole other mystery. Again I will assume that the crossover outputs are post EQ so changing the pre-amp settings will affect both crossover outs the same.

If the 2x10 is a full range cab, might not be much point, biamping is more for when you have specialist cabs for certain frequency ranges, for bass purposes, that often means running a guitar rig for mid and up, sending the crossover out above 100hz to a guitar rig so you don't toast the speakers, and leave the lows to a bass rig or sub. Running the bass rig full range and the guitar rig high passed gives a big sound.
