A ground-up design, the PM-11S1 fulfills the promise of no-compromise sound with the finest wideband sources. It also preserves the simple yet elegant design that has distinguished Marantz for more than half a century. An unequalled array of technology and craftsmanship reside inside the champagne-finished, copper-plated chassis. The PM-11S1’s circuitry draws directly from the SC-9S1 preamplifier and MA-9S1 monoblock power amplifier. A toroidal transformer forms the heart of a prodigious multi-segmented power supply that thoroughly isolates each stage and allows the wideband amplifier section to double its output as speaker impedance drops. All inputs and outputs, including the MM/MC phono, are buffered with Marantz's HDAM-SA modules to insures satin-smooth signal transfer. The precision Wolfson WM8816 volume control and WBT speaker terminals merely hint at further refinements. A floating control bus synchronizes multiple PM-11S1s for use in the finest multi-channel music systems. • SC-7S1/MA-S1 Inherited Design • Massive Hybrid Toroidal Transformer • Choke Input System Power Supply Circuit • Fully Balanced Pre-Amplifier Construction • Dual Mono-block Power Amplifier Construction • Evolved New HDAM® SA2 • High-precision Liner Volume Control • Marantz F.C.B.S (Floating Control Bus System) for the Ultimate Multi-Ch Configuration • Zero Noise LCD Display Power output: 100 watts per channel into 8Ω (stereo) Frequency response: 5Hz to 120kHz Total harmonic distortion: 0.01% Damping factor: 100 Input sensitivity: 0.27mV (MC), 3mV (MM), 240mV (line) Signal to noise ratio: 76dB (MC), 90dB (MM), 96dB (line) Output: 1.9V (Pre out) Speaker load impedance: 4Ω to 16Ω Dimensions: 440 x 165 x 444mm Weight: 26kg Accessories: remote control RC-001PM
