Description
Atoll PR300 Signature : Preamplifier
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.
