      6. Amplifier

      Onkyo TX-NR7100 Onkyo TX-NR709

      9 channel Amplifier: Onkyo TX-NR7100 features 9 channel power amplifier. It is rated at 100 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      7 channel Amplifier: Onkyo TX-NR709 features 7 channel power amplifier. It is rated at 110 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      • Dynamic Audio Amplification: Onkyo TX-NR7100 features Dynamic Audio Amplification which is Onkyo’s amplification philosophy that focuses on capturing the energy and dynamism contained in the audio signal and reproducing it without loss. Audio signals are not static like a test tone, but rather a countless collection of constantly moving waves. While static measurements such as S/N ratio and Total Harmonic Distortion are important, Onkyo believes that excellent dynamic and transient response is the key to emotionally involving sound. Dynamism - the “life” in music - is achieved when the amp can respond to changes in the signal instantaneously, so notes start and stop naturally and the nuances in attack, decay, sustain, and release are voiced with conviction. Onkyo home theater receivers represent the culmination of almost 70 years’ experience in amplifier design. The unique elements of their amplification system comprise high-current, low-impedance architecture to accurately control large speaker cones while enabling instantaneous response to dynamic changes, and discrete wide-range amplifier circuit topology to eliminate phase shift for clear and accurate audio imaging.
      • WRAT (Wide Range Amp Technology): Onkyo TX-NR709 features Onkyo’s Wide Range Amp Technology (WRAT) circuit layout that prevents phase shifting by pushing the roll-off point higher than the listening-level frequency. Amplifying sound without phase shift creates an uncommonly well-focused and realistic audio image. If phase shift occurs and signal timing is not accurate, then neither is the resulting audio image.
      • 3-Stage Inverted Darlington Circuitry: Onkyo TX-NR709 features 3-Stage Inverted Darlington Circuitry. Standard amplifiers employ a negative feedback (NFB) design that counters distortion by feeding back the opposite phase of the output signal into the input stage. Unfortunately, NFB is easily affected by inverse electromotive forces from the speakers, leading to an increase in circuit noise. Three-Stage Inverted Darlington Circuitry is a core Onkyo technology incorporating a low-NFB design that makes the sound more natural. Sensitive to oscillations, this circuitry requires very advanced control technology in order to be incorporated into the amplifier.

      THX™ certification

      Onkyo TX-NR7100 is THX™ Select™ (previously known as Select2) certified. This means that it is for medium sized rooms, up to 2,000 cubic feet in size, with a 10-12 foot viewing distance from the screen.

      Onkyo TX-NR709 is THX™ Select™2 Plus certified. This means that it is ideally suited for a room where the screen-to-seat viewing distance is approximately 3 to 4 meters, and the room size is approximately 56 cubic meters.
