oki.. Jag hittade den här artikeln som belyser frågan rätt bra:
"...you may sometimes find that your mix is clipping at the bus-input stage, and Cubase gives you a few options for handling this. First, you could reduce the level of all the channels feeding the bus — but, whichever way you choose to do this, it’s a faff once you’ve started to use automation, or threshold-sensitive processing on groups or effects channels. Alternatively, you can use the input trim control at the top of the bus to attenuate the signal before any processing. Given the floating-point processing, that’s a perfectly acceptable approach — though unecessary if you get the levels right in the first place! Finally, you can use the input gain of the first insert plug-in on the bus to attenuate the signal, which is essentially the same thing."
Forts...
