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.

XMOS SPECIFIC DRIVER

Important: Using the USB input of the optional DAC board requires downloading a specific driver for Windows computers. This can be downloaded below. This driver is not necessary under MAC and Linux.

Serial remote control (allowing to control all products: Integrated, CD Players, Tuner, DAC).

“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, with all options acquired, tops out at 3,000 euros. You have to start seriously racking your brains to do better.”
