About the SB-301 mkII

The Plinius SB301-MKII is a robust stereo power amplifier designed for demanding music and theatre applications. It delivers 310 watts continuous per channel into 8 ohms with less than 0.2% total harmonic distortion across the full audio band (20Hz to 20kHz). The amplifier features a large power supply and rugged output stage with double the output devices of the SA-103 model, operating in Class AB bias for lower operating temperature. It offers both RCA and balanced XLR inputs, with gains of 32dB and 38dB respectively. The unit is capable of delivering short duration peak currents of up to 100A per channel, fuse protected. It has a frequency response of 20Hz to 20kHz ±0.2dB, with -3dB points at 1Hz and 70kHz, and a signal-to-noise ratio of 100dB A-weighted. The amplifier includes features such as a mute switch, standby mode, trigger input, and ground lift switch. It is available in black or silver finishes, housed in a massive aluminum chassis with large heatsinks, weighing 38kg. Dimensions are approximately 220mm high, 500mm wide, and 455mm deep. The SB301-MKII is known for delivering dynamics, finesse, and transparency, maintaining sonic quality at high power levels.
