With its robust construction and advanced circuitry, the A-48 offers a level of control and authority that is second to none.\u003c\/p\u003e\u003cp\u003eAt the heart of the A-48 lies a fully balanced Class-A amplifier circuit, ensuring exceptional linearity and low distortion. The amplifier's power supply is designed to provide clean, stable energy, even during demanding listening sessions. The result is a sound that is both powerful and refined, capable of driving even the most demanding speakers with ease.\u003c\/p\u003e\u003cp\u003eFeaturing a six-fold parallel push-pull architecture, the A-48 harnesses a wealth of advanced technology. Its outstanding performance is exemplified by a signal\/noise ratio of 117 dB, output of 360 watts into 1 ohm (music signals), and a damping factor of 800. The newly designed output protection circuit can detect any short-circuiting of the speaker terminals, for complete peace of mind. This power amplifier is the ultimate instrument for immersive music appreciation on the highest level.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cp\u003e- Pure Class A operation delivers quality power: 45 watts x 2 into 8 ohms\u003c\/p\u003e\u003cp\u003e- Power MOSFET output stage features 6-parallel push-pull configuration\u003c\/p\u003e\u003cp\u003e- Further improved MCS+ circuit topology\u003c\/p\u003e\u003cp\u003e- Current feedback principle combines stable operation with outstanding sound quality\u003c\/p\u003e\u003cp\u003e- Bridged mode allows upgrading to true monophonic amplifier\u003c\/p\u003e\u003cp\u003e- Large high-efficiency toroidal transformer\u003c\/p\u003e\u003cp\u003e- 4-stage gain control\u003c\/p\u003e\u003cp\u003e- Balanced remote sensing\u003c\/p\u003e\u003cp\u003e- Two sets of large speaker terminals\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eContinuous Average Output Power (20–20,000 Hz): Stereo operation (both channels driven) - 360 watts per channel into 1 ohm, 180 watts per channel into 2 ohms, 90 watts per channel into 4 ohms, 45 watts per channel into 8 ohms.
