      5. Amplifier

      Onkyo TX-SR309 Onkyo TX-NR5009

      5 channel Amplifier: Onkyo TX-SR309 features 5 channel power amplifier. It is rated at 65 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

      9 channel Amplifier: Onkyo TX-NR5009 features 9 channel power amplifier. It is rated at 145 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-NR5009 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-NR5009 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.
      • Toroidal Transformer: Onkyo TX-NR5009 has a toroidal transformer which in general costs several times more than a regular C-core transformer and radiates less electromagnetic noise outside its donut shaped core.

      THX™ Ultra2 Plus certification

      Onkyo TX-NR5009 is THX™ Ultra2 Plus certified. This means that it brings the cinematic experience to large home theaters, 3,000 cubic feet (85 cubic meters) in size, with a viewing distance of 12 feet (4 meters) or greater from the screen.

      6. Speaker Configurations

      Onkyo TX-SR309's and Onkyo TX-NR5009's amplifiers can be assigned for different speaker configurations.

      • Configurations: Available configurations are:
      • Onkyo TX-SR309: 5.1 with internal amplifier.
      • Onkyo TX-NR5009: 5.2, 7.2, 9.2 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-SR309: Does not support.
      • Onkyo TX-NR5009: 9.2.
      • Bi-Amp: Onkyo TX-NR5009 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.

      7. Immersive Audio Formats

      Audyssey DSX

      Onkyo TX-NR5009 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.
