The PR300 Signature belongs to the range of preamplifiers and power amplifiers offered by ATOLL. This preamplifier represents the modularity and the power that ATOLL wants to put forward: a wide range of combinations and a considerable source of improvements. All our power amplifiers can be associated with an integrated amplifier or an Atoll preamplifier. They can be bridged in mono mode and cascaded in multi-amplification mode.

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

The PR300 Signature is available in black or natural aluminium:
