PR300 Signature

The PR300 Signature belongs to the range of preamplifiers and power amplifiers offered by ATOLL. This preamplifier represents the modularity and the power that we want to put forward: a wide range of combinations and a considerable source of improvements. Its double pair of Pre-out allows to easily combine a power amplifier and a subwoofer.

“Writing on ATOLL is an eternal and enjoyable start over, but for some time now, we have felt that ambition has risen significantly on the Channel side. If the new factory galvanises their team so much, I wouldn’t know how to suggest that they immediately increase their surface area. The PR300/AM200 Signature couple is a wonderful combination which, with all options acquired, tops out at 3,000 euros. You have to start seriously racking your brains to do better.”
