SR300 - Amplifier - 2x 150w @ 4 Ohms
The SR300 is the first member of the Studio Reference Series power amplifiers from Yorkville. The new SR-300 is designed with more than just the studio in mind though.
The physical package is made up of a heavy gauge steel chassis with reinforced rack mount ears that make it ready for the road. A built in peak and average limiter protects studio monitors or other speakers from potentially harmful signals and keeps the output of the amplifier clean when operating near maximum power. The heat sinks are mounted on the side of the amplifier where the unit can dissipate heat up the side of the rack, away from other heatsinks in the rack.
