      6. Amplifier

      Onkyo TX-NR509 Onkyo TX-NR809

      5 channel Amplifier: Onkyo TX-NR509 features 5 channel power amplifier. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

      7 channel Amplifier: Onkyo TX-NR809 features 7 channel power amplifier. It is rated at 135 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-NR809 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-NR809 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™ Select™2 Plus certification

      Onkyo TX-NR809 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.

      7. Speaker Configurations

      Onkyo TX-NR509's and Onkyo TX-NR809's amplifiers can be assigned for different speaker configurations.

      • Configurations: Available configurations are:
      • Onkyo TX-NR509: 5.1 with internal amplifier.
      • Onkyo TX-NR809: 5.2, 7.2 with internal amplifier.
      • Front Wide Channel support: With the presence of two front wide speakers you can enhance the front surround stage. The following speaker configurations are available for front wide channels:
      • Onkyo TX-NR509: Does not support.
      • Onkyo TX-NR809: 7.2.
      • Bi-Amp: Onkyo TX-NR809 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.

      8. Immersive Audio Formats

      Audyssey DSX

      Onkyo TX-NR809 supports Audyssey DSX which allows you to augment a standard five-channel home theater with either two Front Wide or two Front High speakers. The Wide channels create an expansive soundstage and bring out convincing directional effects. Alternatively, Height channels can add a vertical dimension to movie and game soundtracks.
