      6. Amplifier

      Marantz SR7009 Onkyo TX-SR309

      9 channel Amplifier: Marantz SR7009 features 9 channel power amplifier. It is rated at 125 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      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).
      • Current Feedback Topology: Marantz SR7009 features Current Feedback Topology which is a well known, Marantz’ original circuit technology. The Current Feedback amplifier technology fits perfectly with the high requirements set for Super Audio software providing wide-bandwidth, high-speed reproduction. The impedance at the Current Feedback point is limited resulting in a very low phase shift. Marantz receivers and amplifiers equipped with Current Feedback can keep the phase compensation via Negative FeedBack (NFB) to a minimum, resulting in high through-rate, excellent transient response and superb sonic transparency for the full bandwidth. Unlike conventional Voltage Feedback amplification, the Current Feedback amplification makes the power amplifier in-sensitive to difficult loudspeaker loads.
      • HDAM (Hyper Dynamic Amplifier Module): Marantz SR7009 features exclusive Marantz HDAM (Hyper Dynamic Amplifier Module) technology found on their Reference Series components. Marantz developed its own discrete circuit boards to replace standard IC's. These HDAM's consist of discrete surface mount components with short mirror image L/R signal paths. Those devices are doing exactly the same thing as the Op-Amps, but outperform the regular IC Op-amps dramatically in terms of the Slew Rate and reduced noise level, resulting in a much more dynamic, accurate and detailed sound. Over the years Marantz developed different types of the HDAM to improve quality and to fit to the special requirements of a product category like CD or amplifier.

      • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
      • Marantz SR7009: 5.2.2, 5.2.4, 7.2.2 with internal amplifier and 7.2.4, 9.2.2 with addition of external 2 channel amplifier.
      • Onkyo TX-SR309: Not supported.
      • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
      • Marantz SR7009: 5.2, 7.2, 9.2 with internal amplifier.
      • Onkyo TX-SR309: 5.1 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:
      • Marantz SR7009: 9.2, 9.2.2.
      • Onkyo TX-SR309: Does not support.
      • Bi-Amp: Marantz SR7009 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

      Dolby Atmos

      Marantz SR7009 supports Dolby Atmos.

      Auro-3D

      Marantz SR7009 supports Auro-3D.

      • Auro-Matic upmixer: Auro-Matic upmixer takes non Auro-3D sound and upmixes to the current speaker configuration.

      Audyssey DSX

      Marantz SR7009 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.

      10. Inputs and Outputs

      Audio

      • Phono Input: There is an MM phono input on Marantz SR7009 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
      • 7.1 Multichannel Input: In case you have a high quality Blu-Ray or a DVD player with multichannel analog outputs you may connect it to a 7.1 multichannel analog inputs of Marantz SR7009 and use high quality DACs of the player instead of the ones in the receiver.
      • Analog Pre-Outs: Marantz SR7009 has 13.2 preamplifier outputs which allows you to connect the receiver to the external power amplifier. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the receiver to power the rest. Also, Marantz SR7009 has 11 channel processing but has only 9 channel amplifier, so it needs external amplifier connected to the analog pre-outs in order to reach its maximum speaker configuration.
