Rig Hookup Help?

[minginitis]

Hey guys, I decided to build a split pre/power rig and I clearly have no idea what I’m doing. Where do I connect the preamp into the power amp? And where do I connect the power amp to the cab? I’m also only using a single 410 cab. Mono or Stero (keeping Channel B on 0)? Photos attached. Thanks!

"Full Range" out of preamp into "A" input of amp. Speaker "A" out of amp into your speaker cabinet. Mono. And have the power cord on the preamp fixed.

Pretty sure this is the manual for that amp -> Invalid Link Removed

^what he said, but I doubt if it matters if Stereo or Mono is selected as you only get to use one channel A anyway.

So long as the channel input and output were the same you could use B and B and select Stereo.

Other option, find a little 110 or 112 cab to use on HF and biamp your 410 as the low. Then you would send high out of preamp to one channel and low to the other in Stereo mode.

All true, was just keeping it straight-forward to get him going safely.

Thanks I got sound! Anyone know what the balanced and unbalanced outputs would be used for on the poweramp?

DI outs to a mixer or recording interface.

So both the pre and the poweramp have DIs. Is there a benefit to using one over the other?

Extra options to send both local and distant at line level.

The amp DI will only ever be as quiet as the one off the preamp but frequently just a little more noisy.

The power amp outputs aren't necessarily DIs, as much as for other power amps, but could probably function fine as such.

Yes, this makes more sense.

...and make sure you use a 'speaker' cable to go from the amp to the speaker!

I'm curious, what model is your preamp?

Peavey Max Bass Preamp

I recognized it right away. One of the best tube pre's ever made! And a terrific bang for the buck!

I used the full range output. The first picture is correct. The 1/4" to 1/4" is an unbalanced two conductor TS (tip/sleeve) connection. Fine for a short run like this.

Oh, cool! I had one briefly, but not long enough to bond with it and recognise the back panel. That preamp has the potential to be used as a High Pass Filter (HPF) later on, if you ever feel like looking up the benefits of those and using your rig that way.

I note the rear of the power amp shows 250 watts at 4 ohms impedance. The 4x10 is 8 ohms. It will work, however, your power from the amp will be reduced to about 50% to 70% of 250 watts (125 to 175 watts).

250watts @ 4ohms stereo, 380watts @ 4ohms mono. Yeah at 350watts 8ohms RMS the cab is a little underpowered. Luckily this is a practice cab and I don’t currently need the volume. I’ll probably end up matching another 8ohm speaker in parallel to get some wattage back.

This. You don't record off your power amp, you typically run it to the next one and the next one and the next one to power the whole line array / speaker stack / collection of stage monitors / whatever.
