Music, when you hear it in all its glory, has the power to lift the spirits and transport you into another realm. Signal quality on the MR is meticulously preserved by new AWRAT technology, while three-stage inverted Darlington circuitry provides extremely efficient power output.
And to minimize errors in stereophonic playback, the amplifier incorporates a totally symmetrical alignment of power devices for left and right channels. Despite being beyond the normal range of human hearing, frequencies above kHz are susceptible to clock pulse and other forms of distortion from digital devices. Low Negative-Feedback Design Too much NFB makes a system susceptible to counter-electromotive force from the speakers, resulting in a drop in perceived sound quality.
To avoid this, Onkyo focuses on improving the frequency response and reducing distortion, without relying so much on NFB. Closed Ground-Loop Circuits The MR employs a sophisticated closed-circuit design in which each circuit has a separate link to the power supply.
This helps to cancel individual circuit noise and keep the ground potential free of distortion.

Symmetrical Twin-Monaural Construction Power devices for the left and right channels of the MR are aligned symmetrically. Each channel has the same electrical and structural design, and signal pathways are uniform in length.

This helps to minimize errors in stereophonic playback. Extremely sensitive to oscillations, this circuitry requires very advanced control technology in order to be incorporated into the amplifier.
You can use the BTL feature in conjunction with a compatible pre-amp and a second power amp to double the power output for left and right channels. Audiophile-Quality Parts The MR incorporates two massive toroidal transformers that reduce magnetic flux leakage, improve efficiency, and keep the power supply stable.
Also on-board are a sub-transformer and four 27, microfarad capacitors that work to make the current significantly smoother. Gold-plated, machined solid brass terminals ensure an extremely clean connection. New Circuit Board Construction Rather than being directly connected to the chassis base, the circuit boards inside the MR are cushioned by internal struts and affixed to the front, side, and rear panels.
This method of construction prevents vibrations from the chassis from adversely affecting the circuit boards. Separate Panel Construction The MR features separate aluminum panels for the top, sides, and front to reduce unwanted vibrations caused by internal resonance.
Compared to a one-piece chassis design, this construction method offers greater rigidity and improved noise reduction. Authorised Internet Dealers.
