      6. Amplifier

      Onkyo TX-NR474 Onkyo TX-SR444

      5 channel Amplifier: Onkyo TX-NR474 features 5 channel power amplifier. It is rated at 135 W (6 Ω, 1 kHz, 1 channel driven) and is able to drive 4 ohm speakers.

      7 channel Amplifier: Onkyo TX-SR444 features 7 channel power amplifier. It is rated at 65 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).
      • WRAT (Wide Range Amp Technology): Onkyo TX-SR444 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.
