Acoustic b600c question in regards to the link out.

[HarveyRobertson]

Hey everybody, it's been a spell since I've been in here. Although I do troll the form, I haven't posted nothing in a while. I have a b600c by acoustic. It's a 600 w class d 210 combo. In the back it has a link out. So I have another bass amp with a 15 in it and it's 250 w through its own built-in head. Can I use the link out and feed that into the front end of another amp to drive the second amplifier??

Here's the manual: https://acousticcontrolcorp.com/wp-content/uploads/2022/05/Acoustic-B300C-B600C-Owner-Manual.pdf

The manual refers to the Link In/Out ports as being specific for chaining together Acoustic-branded equipment and they don't list the signal level. I would not run it into the front of another amp without knowing this first.
If your 15-inch combo has an effects loop, you could connect the B600c Effects Send to the 15" combo Effects Return using a 1/4" patch cable. This would mitigate the possibility of injecting too hot a signal into it.
