      6. Amplifier

      Onkyo TX-NR525 Yamaha RX-A750

      5 channel Amplifier: Onkyo TX-NR525 features 5 channel power amplifier. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

      7 channel Amplifier: Yamaha RX-A750 features 7 channel power amplifier. It is rated at 90 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.
      • WRAT (Wide Range Amp Technology): Onkyo TX-NR525 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.

      7. Speaker Configurations

      Onkyo TX-NR525's and Yamaha RX-A750's amplifiers can be assigned for different speaker configurations.

      • Configurations: Available configurations are:
      • Onkyo TX-NR525: 5.2 with internal amplifier.
      • Yamaha RX-A750: 5.2, 7.2 with internal amplifier.
      • Bi-Amp: Yamaha RX-A750 is able to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.
