NuForce MCH3 SE-C7 SPECIAL EDITIONHIGH-END 7 CHANNEL POWER AMPLIFIER NWITH FOUR CHANNELS WORKING/THREE CHANNELS NOT WORKING CIRCUITRY DESCRIPTION AND OWNERS EXPERIENCE:This power amplifier is built using NuForce 9SE based modules - SE is the designation for Special Edition. These are extremely high quality amplifiers and the monoblock version sell for more than 1K for a channel!MCH3 SE-C7 contains 7 identical modules and two power supplies. Unfortunately three of the modules dont pass the self test and, therefore three channels (5, 6, 7) dont work - see red lights in the pictures.I purchased the amplifier from the original owner in this condition as I never intended to use it as a HT amplifier.I used this amplifier to Bi-Amp a pair of Definitive Technology BP-30. The preamplifier used was Proceed AVP and Proceed AVP2 through the XLR connections.Since channels 5, 6, 7 are not functional/not used, the power connectors have been disconnected from these three modules. The amplifier is now configured as a DUAL stereo amplifier: channel 1 and 2 are powered by ONE ASSIGNED POWER SUPPLY and channels 3, 4 are powered by the SECOND ASSIGNED POWER SUPPLY.This way there is COMPLETE SEPARATION between channels 1/2 used for bi-amping left speaker and channels 3/4 used for bi-amping right speaker.The sound was extremely powerful and detailed, not bright just detailed. The bottom end was very well controlled and no subwoofer was ever needed - that is also a characteristic of the speakers.This amplifier is very quite and the music just pups up from a complete black background.CAUTION!PLEASE READ THE INCLUDED MANUAL - I WILL INCLUDE THE PRINTED MANUAL - BEFORE USING THIS AMPLIFIER.NEVER USE THE AMPLIFIER WITH NO SPEAKERS ATTACHED. TURN OFF THE CHANNELS THAT ARE NOT USED!In conclusion, this is a fine piece of equipment aimed to the discerning audiophiles who will certainly enjoy musicality of this amplifier. The NuForce Multi-Channel AmplifiersNuForce’s MCH Home-Theater Series defines state-of-the-art multi-channel analog switching amplifiers.You will be astonished by the power these low-profile (3.5-inch tall) components deliver: explosivedynamics and superb bass control for surround-sound home theater, and for two-channel listening, the rich,exquisitely detailed sound that has earned NuForce its enviable reputation among reviewers andaudiophiles.Based on technology we developed for our Reference 9 SE (Special Edition) amplifier, the MCH-3SEstands as the perfect marriage of home theater and music. As an example of convenience, a wand remote,first introduced with our P-9 preamp, allows the user to switch off the unit’s home-theater channels inorder to optimize two-channel listening. Among the MCH-3SE’s invaluable features is a program thatperforms a self-diagnostic drill every time the unit is powered up.Unlike linear amplifiers, which, even at idle, consume a great deal of power, the power-conservativeNuforce MCH Series provides instantaneous clout when and where it’s required. The MCH-3SE andMCH-3 offer a power reserve of 1200 watts; in effect, any of seven channels can be driven up to 300 wattsinto 4 ohms so long as total power requirements do not exceed 1200 watts. All models in the MCH Series feature XLR inputs along with RCA inputs which can be individuallytrimmed for precise channel matching as well as proprietary five-way binding posts with extremely lowinsertion loss. MCH-3SE-C7 Specifications:• Configuration: 7 channel inputs RCA and true balance XLR• Power output: 7 x 190W@8ohm 7 x 300W@4ohm • Power bandwidth: 100 to 20 kHz +/- 0.8 db 10 Hz -0.5 db 60 kHz -3 db• THD+N = 0.03%, 1kHz, 10W• Input impedance: 45K ohm• Gain: 27 db• SNR = 100 db at 100W• Chassis is made of high-grade anodized brushed aluminum to reduce audio resonance• Dimension: 17 x 14 x 3.5 (height does not include feet)• Worldwide AC voltage (84VAC to 264VAC). No need for AC regulator if the AC voltage falls within the specified range.• Weight: 33 lbs THIS AMPLIFIER WILL BE SHIPPED IN THE ORIGINAL BOX BUT, IT WILL BE DOUBLE BOXED FOR PROTECTION OF THE ORIGINAL PACKAGE AND ITS CONTENT . NO RETURNS ACCEPTED DUE TO THE NATURE OF USED ELECTRONICS.PLEASE CHECK ALL PICTURES AND ASK QUESTIONS BEFORE COMMITING TO BUY.
