Plinius SB-301 MK-II Class A, 310/470 WPC

Very new, low hours (<50), first owner. The SB-301 mkII is a high bias stereo Class A/AB amplifier that delivers 470 watts per channel at 4 ohms. 100 Amps peak current delivery per channel. 30W/CH in full Class A mode. Class A performance PLUS lots of dynamic headroom Switchable XLR and RCA inputs. 2 stereo sets of binding posts for bi-wiring Mute switch. Standby/operate switch. It's a really good stable amplifier when the speakers demand a lot of power to drive bass without distortion or treble with detail and finesse and it will cope with inefficient speakers. The standing temperature is lower than that encountered in full Class A series designs because it runs in Class AB above about 30 watts output. It occupies a niche in audio systems for the person that really loves big dynamic sound like movies and orchestral pieces. The physical construction of the SB-301 is based on the SA series designs so it has the same distinctive aesthetic as the Class A products and indeed much of the electronics topology is derived from that Class A history This amplifier delivers all the dynamics, finesse and transparency that Plinius is renowned for. Like all Plinius products it is very reliable and will rise to the challenge of difficult operating conditions time and time again. POWER 310 watts RMS per channel into 8 ohms. 470 watts RMS per channel into 4 ohms. Both channels driven from 20Hz to 20kHz at less than 0.2% total harmonic distortion FREQUENCY RESPONSE 20Hz to 20kHz ±0.2dB -3dB at 70kHz DISTORTION Typically <0.05% THD at rated power 0.1% THD and IM worst case prior to clipping CURRENT OUTPUT 100A short duration peak per channel Fuse protected RISE TIME Typically 5µs PHASE RESPONSE +0° at 20Hz and -14° 20kHz HUM & NOISE 100dB below rated output 20Hz to 20kHz, A-weighted INPUT IMPEDENCE 47k ohms GAIN RCA Inputs: 32dB Balanced Inputs: 38dB POWER/CURRENT CONSUMPTION 900W 1.6A (370W) Class AB Idle 0.2A (46W) Standby DIMENSIONS Height: 220mm (8 3/4 ") Width: 500mm (19 3/4") Depth: 455mm (18") Weight: 38kg (83lb) Amplifier Configuration Selector (ACS) switch: The rear panel ACS switch allows for the amplifier to be configured for Stereo RCA or XLR modes. Remote Trigger Input: When connected to a preamplifier trigger output, the amplifier will switch out of Standby and be ready for use when the preamplifier is taken out of standby. Ground Lift Switch: This allows for the signal ground to be isolated from the main chassis earth. This can assist in resolving unwanted ground loops or hum due to duplicate ground paths in some systems. WBT and Neutrik Connectors: High quality WBT RCA and Neutrik XLR input connectors are fitted along with WBT output speaker terminals to ensure a low distortion interface between your cables and the amplifier. Auricap Capacitors Audience AV supply the Auricap XO capacitors used in several key areas of the circuit. Siltech Wiring: Siltech premium 'G7' silver/gold wire provides a perfect connection between components to give clear, fast and detailed presentation of the music signal. Aluminium Construction: The aluminium construction provides a rigid non-magnetic housing to eliminate unwanted magnetic fields that can interfere with the sensitive audio signals.
