To ensure plenty of current, Marantz outfitted the PM-11S1 with two 100-watt monoblock amplifiers — one for each channel. The amps take advantage of the same technology found on Marantz's top-of-the-line MA-9S1. Not only is the current clean and abundant, but it's delivered almost instantaneously, so even very complex musical passages come out clean and lifelike with serious punch. Advanced internal circuitry provides virtually noise-free signal transfer, preserving the purity of your audio sources. From Super Audio CDs to your favorite records, the PM-11S1 renders your music with crisp detail, compelling dynamics, and a broad soundstage. And the sturdy copper-plated chassis sports a silver finish for an elegant look. I bought this unit in Germany so its power is set for 230 but I use a small step down converter in the US costing about 40 dollars. 100 watts x 2 channels into 8 ohms (20-20,000 Hz) at 0.01% THD dual monoblock amplifier construction frequency response 5-120,000 Hz (±3dB) signal-to-noise ratio: 96dB 6 RCA audio inputs (including phono input) 2 RCA audio outputs balanced 3-pin XLR input line-level subwoofer output binding-post speaker connectors 2 sets of main speaker outputs A/V remote control included biamp/stereo switch lets you biamp your speakers using two PM-11S1s for even higher-fidelity sound champagne finish weight: 57.2 lbs 17-3/8W x 6-1/2H x 18-5/16D MFR # PM-11S1 What's in the box: Marantz Reference Series PM-11S1 owner's manual PM-11S1 Integrated amplifier 5.5' Power cord RC-11PMS1 Remote control 2 AAA batteries User Guide (English/French/Spanish/Portuguese)
