The SPM 1200 MkII is widely regarded as our most famous power amp and one that neatly combines great performance and fine value for money. The 350-watt powerhouse offers huge reserves of instantly delivered, precisely controlled power.

Using the latest low-distortion amplifier circuitry with our own proprietary lateral-structure dual-die MOSFETs (16 x 150 watt devices per channel), the SPM1200MkII is able to drive more difficult loudspeaker loads effortlessly, with clarity and precision.

At the heart of the amplifier is our own 2KW high-frequency switch-mode power supply with our unique dynamic coupling. The technique allows instantaneous power to be taken from both power rails simultaneously when the music demands, giving perfect balance and dynamic precision.

The technology is complemented by a large bank of energy-storage capacitors that are ‘recharged’ by the power supply many thousands of times a second, giving the amplifier huge reserves and the ability to react without strain, to any signal.

The amplifier offers both balanced and unbalanced inputs (two of each), plus a pair of high-current loudspeaker outputs with gold-plated connections. Simplicity of operation is retained with a single power button to switch the SPM1200Mk II out of standby.
