Class D amps suffer from shaped noise floors which vary dynamically according to signal level. despite its size can deliver 1,000W into 8 ohms and 2,000W inherently flawed. and certainly has its benefits in getting a lot of power out of a small package. first was Class A, the second Class B, the While such generalizations may hold true for other brands of amplifiers, below, Anthem responds to each one as it relates to our M1. Purely capacitive and very capacitive loads will send the M1 into protection mode, not burn out mode but since no speakers are purely capacitive this will never be an issue. Bob Gassal from Anthem Electronics - Paradigm Speakers sister company - has a chat to Stephen Lee from Audio Trends about Anthem and the new pocket rocket M1 Power Amplifier. The resulting pulse-density (not pulse-width) modulated output is claimed to achieve a practical time resolution of 4 nanoseconds (0.000000004s), which is more than an order of magnitude better than that of the DSD coding used on SACD. Right: Power supply with PFC. Pizza Delivery! I also heard the new Cyrus MonoX 300 and Bryston 4BSST2 at … "On class-D amplifiers, I feel that their promise has mostly yet to be fulfilled.". The Statement M1 is a state-of-the-art monaural amplifier delivering 1,000 watts into 8 ohms and 2,000 watts into 4 ohms or less with THD remaining under 0.1% from 20 Hz to 20 kHz. maximum output (the typical working level of an amplifier), our The M1 also doubles down the power when the load is halved, like good amplifier should. As good as it gets! performers. Operation is discrete with output MOSFETs mounted on a copper clad PCB, then on a heavy aluminum extrusion with heat pipes. Keep up with everything Anthem on Twitter. possible loads. Statement P5 amplifier outputs 500W. The M1 does not use a compressor and its output stage is never allowed to clip. "Ever notice how the effect of burn-in is always positive?". capacitors only during the short moments that voltage is at or Lower voltage MOSFETs can be used for lower resistance and higher speed. Number of channels is often 2 channels for stereo systems and 5 or 7 channels for multichannel systems. As a result, while the M1 can put out 2kW continuously into 4 ohms when fed by 240V mains, it can still put out 2kW for the duration of typical musical peaks when fed by a dedicated 120V 15A line, without causing circuit interruption. Since power is the Since the output stage runs at seven times lower frequency than DSD one could argue that the actual resolution is that much lower, but even then it’s 12.5 times better than SACD. Ideal for subwoofers I think, but what about the rest of the system? Wyred4sound kind of tried to kick it off, for the masses, but still a bit (niet). If you don't use your ears, is there another way to experience an an audio product? It is interesting to follow class D technology to see where its going. Anthem Statement M1 Amplifier Specs. First, the ratio of the M1's power output to its size and weight is remarkable, as are its claimed distortion and noise specs. Designed and engineered in our advanced research center in Ottawa, Canada, the M1 … The bus capacitors in the M1’s output stage are replenished 200,000 times per second instead of 100 or 120 times per second as is the case with linear power supplies. It’s immensely powerful, and goes exceptionally loud without any obvious drama, even when driving a known ‘difficult’ load, while the casework and heatsink fins remain merely warm at all power levels. The Statement M1 is a state-of-the-art monaural amplifier delivering 1,000 watts into 8 ohms and 2,000 watts into 4 ohms or less with THD remaining under 0.1% from 20 … signal’s more familiar up-and-down amplitude variation, not at The M1 enjoys all of the attributes of our award-winning Statement Class AB amplifiers but through exclusive Anthem technologies, goes far beyond the current capabilities of Class A, Class AB and prior Class D amplifiers in the market. The MOSFET gates are well controlled, driven by 9-ampere high-speed MOSFET drivers. have the same width. Neither of the above are an issue in the M1. Anthem Statement M1 for sale. Contrary to the bias that exists among high-end enthusiasts and all the same as a digital string of 1s and 0s where all pulses amplifies) the power of the audio signal to levels suitable for driving speakers. No relays are used in the signal path preventing any possibility of relay failure. "That is one reason why I am convinced that the vast majority of these reports are due to observer adaptation. After plugging the interconnects into the XLR inputs and attaching the speaker cables, I left each M1's gain-attenuation switch at 0dB to match the gain of my other amps, and set the M1s' On mode to Auto so that the amps would turn themselves on when they sensed the presence of a signal. The odds are stacked against the Class D amp designer. listening rooms. At 1/8th of its Each of the eight 65-amp MOSFETs can handle a peak current of 260 amperes, has low gate charge for fast response, low channel resistance for high efficiency and high speed for high efficiency and low distortion. I respond to this review as I am looking at this Anthem product reviewed with near perfect technicial measurements. But see my Devialet review in the January 2013 issue (due to hit newsstands next week) for one successful approach. very close to its positive or negative peak. Secrets September 8, 2011. The M1 has no audible effects caused by ‘dead time’ and there is never any overlap to cause electrical problems. The Statement M1 is a state-of-the-art monaural amplifier delivering 1,000 watts into 8ohms and 2,000 watts into 4ohms or less with THD remaining under 0.1% from 20Hz to 20kHz. Power Amplifier. Used sparingly. Power Factor Correction (PFC) maximizes available power and at the I have been looking at Class D amps for a tri-amplified system using the DEQX as a base for xover and dsp (not the digital preamp feature). I'm suprised Anthem would release such a product for they can easily duplicate the measurements in this review. Almost everything he has has tubes. Engineered with advanced load monitoring and power factor correction technology to satisfy demands up to 2400 W, even when connected to a 120V/15A line. Happening on this flat, black slab of an amplifier lying on a display table or bolted to a wall, reminded me of the appearance of the iconic monolith in Stanley Kubrick and Arthur C. Clarke's, PS Audio Stellar M1200 monoblock power amplifier, Classé Delta Mono monoblock power amplifier, Pass Laboratories Aleph 0 monoblock power amplifier, Parasound Halo JC 1+ monoblock power amplifier, darTZeel NHB-468 monoblock power amplifier, Accustic Arts Audio Mono II monoblock power amplifier, Dynaco Stereo 120 transistor power amplifier, Revinylization #13: Tone Poet, Analogue Productions, ERC reissues, Analog Corner #290: The Haniwa LP Playback System, Gramophone Dreams #44: Audio-Technica, Goldring, LP Gear phono cartridges, Cambridge Audio CXA81 integrated amplifier, Analog Corner # 305: Degritter record cleaner & Aidas Gala Gold LE cartridge, Acoustic Geometry Room treatments (before & after), My current and likely the last home audio setup, Fascinating wiev by Verity Audio Sarastro, Recommended Components: Fall 2020 Edition. The voltage and current waveforms are sinusoidal and in-phase. Extensive use of power and ground planes ensures vanishingly low levels of noise and inductance to produce an amp that gets out of the way, leaving only the sound of the music. The “D” in Class D does not stand for Paradigm/Anthem's Rob Sample gives us an inside look (literally) at the 1000 watt M1 Statement mono amplifier. » The M1 can deliver 2 kW continuously when fed by 240V mains and 2 kW for several seconds when fed by a dedicated 120V 15A line. output pulse train in direct relation to the analog input signal. Although it is normally the case, assuming noticeable burn-in, I have encountered several pieces that went from being engaging to too polite. For a high-power amp such as the M1, bridging can be safer. The “D” in Class D does not stand for digital. Frequency response is affected due to feedback not accounting for effects of the output filter. Hand-designed 4-layer FR4-rated glass-epoxy circuit board with 2-ounce copper traces promotes exceptional conductivity. almost purely resistive to the AC source. Although more expensive since more MOSFETs are needed, sound quality is vastly improved. different ilk (see later section on Class D for a full discussion). Also a minor typo: a price discrepancy: "costs $3499 each, $7498/pair" the specs section has what appears to be the  correct price though. Designed and engineered in our advanced research center in Ottawa, Canada, … It also means the there a copper wick returns the fluid to the hotter end of the I was/is/are a t-amp fan, and had high hopes, but, alas, I'm back to class A/B and quite happy with it (very good progress in that area for the record). (See diagrams to right). more to this. 1-bit DSD pulse width modulation used by SACD operates at over 2.8 MHz which is seven times the rate used by the typical Class D amplifier. The Statement M1 is a state-of-the-art monaural amplifier delivering 1,000 watts into 8 ohms and 2,000 watts into 4 ohms or less with THD remaining under 0.1% from 20 Hz to 20 kHz. Although more difficult and expensive to implement, Anthem has always used 2-prong AC cords to make installation easier. pipe. The power LED illuminates during normal operation; the status LED signals codes that indicate different problems with power or temperature, but remains steadily illuminated during normal operation. Actually, leaving aside the burn-in question in general, which I find varies from insignifican to significant depending upon the gear, I do not always find it positive. While one cannot turn these off, a good listener should have a decent awareness of how they determine what we perceive. You can dial up several kilowatts without a blink. possible according to the operating conditions. Anthem was generous in sending me three M1s so that, during the course of my listening for this review—which is essentially of the M1's performance with two-channel recordings—I could also enjoy some multichannel listening: the front left, center, and right channels would have identical amplification. It's been around for a while (not sure, did 47's Gain Card first employ this?) Anthem M1 1000W State of the Art Mono Power Amplifier : The highest sound quality at all volume levels, flat frequency response into any load, and stable into the most difficult loads. My Parasound JC1s have been burning in for years and now sound better than reality. Timing is controlled by high-speed Advanced CMOS Logic gates with 5-nanosecond propagation delay and sub-nanosecond skew. Or does it? same time reduces (by a large amount!) Press. Sealed I look to use the M1 for my bass drivers moving to tube for mid/trebile in 3 … Its high-speed control loop includes high-speed instrumentation-grade op-amps with 100 MHz unity gain bandwidth, 3000V/µs slew rate, high-speed complementary comparators and 5-nanosecond Advanced CMOS Logic gates. efficiency of conventional amplifiers at full output, but there's Watch our information and product videos on YouTube. With the three M1s neatly stacked, their potential to provide three channels of 2000W each into 4 ohms seemed almost a boast—they're smaller and lighter than my regular class-A/B amps, which output 250–300Wpc.
