I hope you at least stack the 15 on the top so you can hear it's cries of pain over the far more able 4x10.

A thing to remember is that if you want to be twice as loud you'll need to increase power by a factor of ten. 800W is 800W whether derived from a bridged power amp or from a single channel of a larger power amp. The risk of damage depends on the capabilities of the connected speaker system. 800W into a 300W speaker system will eventually cause damage no matter how careful you are.

And in Canada too! From the bottom of my heart thank you for caring for the Children and their Mums!!

Are you turning the QSC's level controls to full on?

If the Pod had an XLR it's a pound for a penny that it would have been a low output suitable for connecting to a PA. It would have been quieter that the phone jack. You must remember that many 'on the floor' devices are designed to plug into the front of a bass amp and so have a much lower voltage level than a power amp needs.

Using the binding posts you have to connect your cable to the two red posts and ignore the black ones. In Bridge, one amp channel is fed a signal 180 degrees from the other. Thus when one output goes positive the other goes negative the same amount. In essence one amp drives the cabinets positive pole whilst the other feeds it's negative. Thus twice the voltage is developed across the cabinet. How are you connecting the amp to the Pod?

So you do bridge. It's not that powerful an amp but it is still more than capable of damage. Do you know that some amps require a specially wired speaker cable for Bridge mode? In your case the Speakon connected to Amp1 output has to be wired +1 and +2 at the amp end and +1 and -1 at the cabinet end. This cable is not reversible and it's two ends should be clearly marked Amp and Speaker.

Don't blow your speaker cabinet!!! Don't get tempted to get 'every last watt' out of the power amp by bridging it. Run it in parallel mono with a cab on each channel. if you only have one cabinet, run it on one channel and turn down the other. Use SpeakOn cables and not 1/4" Phone plugs. The 1/4" plugs can't safely handle the power delivered by the amp.

You can get ground lift adaptors to take care of that problem. They are easy to make too.

Quoting @Sapatown I got it checked by a really good amp tech that knows his stuff, and he found some loose transistors and a cable that needed to get fixed. I could be missing something but the Matamps I can remember were all tube/valve and had none of those pesky transistors.

I was around the same age and also knew no better but still felt like I had 'arrived' 'cos I had a VOX. LOL

Indeed!

Are you in training perchance?

My second worst amplifier was the VOX AC50 with it's 18" Foundation cabinet. VOX didn't even put handles on the cabinet so I had to add a pair in order to move it about. The amp had no treble at all as it was EQ'd out by circuitry in the pre-amp. Another ugh! I redid the whole amp to make it better for my use. If anyone has an AC50 with two channels, an engraved fibre control panel and chrome knobs that was my old unit. It was last seen in Liverpool.

250W into a single 12 is looking for trouble especially with a bass!

Well I do miss my old friends and there are a lot of messages I can't get to. A few of the TB people I do find here including your good self!

I always am surprised by the prices in my old country. It's just about worth it to fly to the US and bring one back. I guess we have Boris the Spider to thank for that!

WHAT?? TRUMP THINK? Wow whoda thunk! LOL Warning about the guy got me canned from Talkbass so I'll shut up now!

The cable you are using to connect the amp and cab is a SPEAKER cable and not a coax instrument cable yes?

And I love mine!!

True dat!

That's a good example of Sod"s law!

But at least it's not made in Russia!!

I wonder how they would compare to my Sixties unit? I have to admit that I find the chrome chassis a bit garish.

I hope it serves you well.
