Mixing up dB, dBV and dBU is always going to confuse. I always figured the 0dB on the back of the RBI was so the -20dB pad would have a reference. My RBI had no problem spinning up an old NZ PA amp or a Crown XTI. Afaik they were both standard 1.4V sensitivity input, being 0.7v per leg on a balanced cable. So that would be another potential dog to put down. Is OP running a balanced cable (or shorting half his signal)?

Two pro grade preamps not giving you what you should expect is either user error or your amp isn't operating to spec. 600w is a lot of power, same same as your Ashdown.

Just checking, you are using the 'Sansamp' XLR out from the back of the RBI set to full ( 0dB) output and turning up the XLR on the front panel?

Which part of ''Mike Smethurst ripped me off'' don't they understand? EVERYONE needs to report their FB experience in one 12 hour window or it forgets? Every 6 months I get an email from FB ''we see you have been having trouble participating, perhaps you have forgotten your password, here's a direct login link..''.Unfreakinbeleivable.

You should check the DCR on the 410. If it's 4 ohm the amp might go for a while at 2.7 ohms but the extra heat will do it in.

Reading between the lines it sounds like the previous bridge mono didn't happen so it must have been two cabs on one channel only? Still should have raised the roof. Makes me wonder what could be wrong. Dip switches? Protection mode from wrong cable? Gain stages up the wazoo? User expectations?

It would be very easy for the bridged amp to go all Django Unchained on your cabs. 360w a side really should be making plenty of noise. I have zero confidence in a 600w rating on a 15. I tend to discount those by 50% before they start to strain. So the 360w per channel is ample.

How did you know you can do that? I didn't know about debit card chargebacks until I met that joker. He worked for donations. I guess he felt charging for something that should be common knowledge was bad form. The sorts of sums involved would probably make for very grateful clients. European holidays out of NZ don't come cheap.

If you tempered it with a Fletcher-Munson loudness curve it would be amost equal between bassy bass and vox? That's how I hear reggae anyway.

Read the fine manual! Not too many power amps bridge into 4 ohms so I would knock that off until you have RTFM. Parallel is for 1 cab on each channel, Mono is both cabs on just the one channel. Should be much of a muchness until you get to the bleeding edge of headroom exhaustion. I wouldn't like to guess what your cabs can handle or what the amp can put out. Most likely cabs give out before amp. Bring up the output of the RBI until the QSC indicates. Then bring up the QSC output. Should get pretty damn loud.

I met a joker who made a business out of helping people get refunds for holidays paid for but not supplied due to covid. He said if it went through the merchant banking credit card systems then you're good. But you have to kick up about it. If you look at your coffee receipt for your Debit Card tap and go it will say CREDIT on there somewhere and a little piece has been snaffled by the merchant's bank. Part of that goes to the card companies that own that side of the system and part to the bank. If you put the debit card chip in and push the buttons it goes through eftpos and it's free, because banks don't have to handle your cash. Figured it out yet?

If paying by debit or credit card your payments are guaranteed by the merchant bank who has been taking fees all the long years in anticipation of having the occasional horse go lame along with the astounding profits. Banks don't tell you this, you have to ask.

You do you. Me, I am a 1kGBP thereabouts bassist. Plenty of other bassists can play circles around me. If I showed up with a Sadowsky or a Fodera nobody would notice. Equally nobody would notice if I showed up with a Squier.

If you are lucky you're alright. Iirc they made them in both 4 ohm and 8 ohm. Unfortunately they used pens with ink that all faded away so the only way to tell is put a multimeter across a 1/4" lead and see how many ohms it reads. Should be around 6 ohm of DCR for an 8 ohm cabinet. 125w per cab won't be a problem so long as the combo is on top where you can hear it. Either way if you whipped up a couple of 210 cabs you could take the amp out of the combo and make a good little easy shifting rig.

At some point rack stuff becomes too painful to let go for the fraction of what you paid for it. I thinks it's getting to where really good low noise stuff stays in service and lesser stuff stays as backups with a very few buyers snaffling the occasional offering.

Fruit contains potassium makes you warm.

There probably is, but what I would be looking for is a 'light' 5 string set since C is a lot closer to B than E. If you are doing some weird 'guitar shaped' tuning you're on your own. It would not be too hard to plot frequency vs gauge for a given scale length and draw a curve. It might look better if you used the area of the string instead of the gauge. Have fun.

Eat a couple of ripe bananas two hours before you go on.

Too bad all the function band bassists wind up like James Bond tied naked to a chair frame with no seat in it.

Not 'arf! I'll complicate it some more. Often something simple does stick out like a sore thumb but be totally appropriate.

My broker explained it to me. Basic tenet of insurance is a risk can only ever be covered by one policy. It follows from the essential nature that the same risk cannot be insured twice by two parties. If your gear falling on punters is covered by MU your problem seems to be they want you to be responsible for the actions of their punters on their stage and any other paid subcontractors you bring along.

We have those XLR's in the wall feeding the ceiling speakers in bars except they don't mind bands bringing whatever else along. I wonder if you piped a keyboard held note and brought it up until it got garbled, and brought it back to clean would that tell you where you could push your mixer output to?

Egad's, they spend a gazillion quid on a system that won't tell you you're clipping it until you hear it?

If the worst came to worst could everyone break out a backup acoustic instrument and make your singers really work? That would be a wedding band to remember.

Hard high passing will get a less tortured sound than zeroing your bass knob, if you find the traffic light is on you.
