    However, during the calibration procedure, you will select the microphone inputs, and you will later switch to an HDMI source to verify the sound of the system. At some point, the SDP-75 may be set to slave mode but may not be receiving any clock information if the digital source is not connected.

You must create in the SDP-75’s user interface a speaker configuration that includes all the speakers of your installation (including the subwoofers).

  • Page 84: An Example Of A Specific Speaker Layout

    AN EXAMPLE OF A SPECIFIC SPEAKER LAYOUT The SDP-75 is designed to support any speaker layout. This includes standard speaker layouts such as those specified by Dolby, DTS and Auro-3D, but also hybrid speaker layouts based on two or more speaker placement recommendations.

  • Page 85: Available Initial Layouts

    DTS:X - 7.1.4 Tops (7.1 + Ltf/Rtf + Ltr/Rtr) STANDARD LAYOUT In addition to the Dolby, DTS and Auro3D templates, the SDP-75 includes a set of standard layouts. These layouts are based on a 7.1 surround layout with additional speakers to support multiple surround and 3D formats such as Dolby Atmos, DTS:X and Auro-3D.

  • Page 86: Select An Initial Speaker Layout

    The Speaker/Room setup tool cannot display more speakers than the total number of available outputs in your SDP-75 configuration. There are 16-channel, 24-channel and 32-channel SDP-75 models. For example, if you have a 24-channel SDP-75 model, the Speaker/Room setup tool will display up to 24 speakers.

  • Page 87: Adding Speakers

    The side panel gives you some information on the prerequisite conditions for some speakers. NOTE: If you choose to add a speaker, the SDP-75 will automatically suggest to add the mandatory associated speaker(s). This will help you to keep the integrity of the recommendations of each decoder.

    This causes incompatibility issues that could make it difficult to play the required content correctly. In the SDP-75, each speaker can be assigned to a specific channel for each format in such a way that it will play the required content regardless of the format being decoded.

  • Page 92: Send Pink Noise To Verify The Routing Of The Speakers

    In the example below, the SDP-75 has automatically assigned the Left top front (Ltf) channel, initially specified as an Atmos speaker, to play the Height Left (HL) channel of Auro3D content.

    Figure 65: sending pink noise to the speakers IMPORTANT NOTE: The SDP-75 needs to be synchronized on an audio clock, either external (Slave mode) or internal (Master mode) in order to produce the pink noise. If a Digital source is selected with no synchronization signal, the pink noise won’t be produced. In such case, we simply recommend selecting an analog source.

  • Page 94: Specify An Array Of Speakers

    Once your speaker’s layout has been declared, configured and fully tested, you can now set up your arrays of speakers. The SDP-75 is able to duplicate the incoming channel from the decoders on several speakers.

    The Stacked subs option is designed for stacked multiple-subwoofers configurations. When multiple subwoofers are used to reproduce the same signal, the perceived level increases. The SDP-75 automatically decreases the signal sent to each subwoofer to maintain the same perceived level depending on the number of subwoofers used to reproduce the same signal.

For every speaker in the room, a target curve can be defined in terms of: Amplitude only Amplitude and Phase Amplitude and Group Delay One or more channels can be linked in order to share the same target curve for several speakers.
