Thank you, that is helpful, but I'm still too nervous to turn it on. That resource led me not only to manuals, but to a Linn FaceBook group and contact information for Linn corporate headquarters, so I will probably get my answer, thank you!
The manual for the amp shows the preamp input and speaker output jacks, but it doesn't specify which of the two pairs of speaker cables for each side goes in which jack. It is a five channel amp, being used as a four channel amp, in Aktiv mode to drive four sets of drivers. One channel powers the right bass/midrange drivers, another the right tweeter, and two more for the other side. I don't want to send bass and midrange signal to my tweeters. There are five input channels, and I assume I just put left in the first one, and right in the second, but I'm nervous about assuming.
