  • Page 18: Video Inputs - Hardware Connections

    Video Inputs - Hardware Connections Video Input Connection - HDMI The B&K surround receiver provides 6 HDMI A/V inputs. HDMI carries both audio and video, B&K allows options to process audio and video separately (please see the menu setup for further options). To connect an HDMI video source to the B&K, connect the HDMI cable to the HDMI output on the source piece.
  • Page 19: Video Input Connection - S-Video

    Video Inputs - Hardware Connections Video Input Connection - S-Video The B&K surround receiver provides eight sets of component video inputs. These inputs may be used with the S-Video to RCA adapter that is supplied with the receiver in order to up-convert an S-Video signal to go into the component input. Connect the one end of the S- Video to RCA adapter to the S-Video output on the source piece.
  • Page 20: Video Outputs - Hardware Connections

    Video Outputs - Hardware Connections Video Output Connection - HDMI The HDMI output connection on the receiver carries High Definition video to your television or monitor. To connect an HDMI video out- put from the B&K, connect the HDMI cable to the HDMI output on the B&K. Then connect the other end of the cable into the correspon- ding HDMI input on your television or monitor.
  • Page 21: Audio Inputs - Hardware Connections

    Audio Inputs - Hardware Connections Audio Input Connection - HDMI Although HDMI connection carries both audio and video, B&K can process audio and video separately (please see the menu structure for further information).

    The IR chain is used for two way communication with the CT 600.3, 600.1 or 300.3. When linking multiple CT products (see the CT man- ual) the AVR 707 would be last unit in the chain. Shown are two CT 600.3 linked as follows: Out of 1st CT to In of 2nd CT, Out of 2nd CT to IR Chain of AVR 707.
  • Page 27: Control I/O And Antenna - Hardware Connections

    One control input trigger is provided that may be used for theater events such as land-line telephone and doorbell notification. The con- trol input trigger on the AVR 707 allows up to 24VAC or DC voltage sensing. Referred to as Page / Events, typical applications might involve a doorbell and front door security camera.
  • Page 28: Hqv Video Processing

    HQV Video Processing Temporal Noise Reduction A temporal noise filter takes advantage of the fact that noise is a random element of the image that changes over time. Instead of simply evaluating individual frames, a temporal noise filter evaluates several frames at once. By identifying the differences between two frames and then removing that data from the final image, visible noise can be reduced very effec- tively.

    Aspect Control Using the power of Reon HQV video processing, the AVR 707 currently provides 5 programmed video aspect ratios for dis- playing video on a 16x9 monitor.

    Audio Modes and Speaker Selections B&K incorporates a state-of-the-art software and hardware system that will prioritize the incoming audio signals (Plug n Play) and accordingly select the appropriate number of speakers, two-channel surround decoder (Dolby Pro Logic IIx or DTS NEO:6) or multi-channel surround mode (Movie or Music) depending on the user’s preference.
  • Page 46 Audio Modes and Speaker Selections Material correctly mixed for Dolby Pro Logic contains no bass information in the surround channels and therefore, Dolby requires that no surround bass is mixed to the subwoofer when you have small surrounds. However, many video game systems do end up with bass information in the sur- rounds.

    BKcSuite System Settings - Audio Speaker Size Speaker size refers to be frequency range a speaker can handle. Audio mate- rial, particularly Dolby Digital and DTS movies, often contain large amounts of bass. If this bass information is sent to small speakers that are incapable of reproducing bass, then this information will be lost of distorted.
  • Page 62: Speaker Level

    (An SPL of 75 dB is recommend- ed). Note: The tone generator and noise selection settings in BK Suite will appear once a AVR 707 is found and the Speaker Level is selected. This is the only time this option will appear.
  • Page 63: Crossover And Lfe

    BKcSuite System Settings - Audio Crossover and LFE Crossover Frequency - Sets the frequency at which bass tones are filtered from the small speaker channels and sent to the subwoofer. The crossover point is the frequency at which the amount of information in the subwoofer and main speaker(s) is equal.
  • Page 64: Room Resonance (Notch Filters)

    BKcSuite System Settings - Audio Room Resonance (Notch Filters) No speaker has perfectly flat frequency response. These deviations in frequen- cy response contribute to each speaker's characteristic sound. This is why one speaker might be preferred over another. When a speaker is put into a room with walls, floor and a ceiling, reflected sounds can cancel or reinforce one another which further alters the frequency response.
