5.1 Surround Setup

Use the Project Properties dialog to set up your project for 5.1 surround.

To preview a 5.1 surround project, you'll need the following hardware:

  • An audio interface capable of six-channel output (either a 5.1-compatible sound card, a sound card with six outputs, or three stereo sound cards).

  • Six powered speakers or six passive speakers with a six-channel amplifier.

Set your project to 5.1 surround modeClosed

  1. From the File menu, choose Properties.

  2. Select the Audio tab.

  3. From the Master bus mode drop-down list, choose 5.1 Surround.

  4. Select the Enable low-pass filter on LFE check box if you want to apply a low-pass filter to each track that is assigned to the LFE channel. Choose a setting from the Cutoff frequency for low-pass filter drop-down list or type a value in the box to set the frequency above which audio will be ignored by the LFE channel.

    Applying a low-pass filter approximates the bass-management system in a 5.1 decoder and ensures that you're sending only low-frequency audio to the LFE channel.

  5. Click OK.

    The track headers and mixer switch to 5.1 surround mode.

Route the Acid mixer outputsClosed

When you're working in 5.1 surround mode, you'll need to indicate where to send the output from your 5.1-channel mix.

Setting your default routing

Use the Audio Device tab of the Preferences dialog to set default routing for 5.1 surround projects.

  1. From the Options menu, choose Preferences. The Preferences dialog is displayed.

  2. Select the Audio Device tab.

  3. Choose a device from the Audio device type drop-down list. Choosing a device type other than Microsoft Sound Mapper or Direct Sound Surround Mapper will allow you to choose specific devices for playback of each of the three stereo pairs.

    NOTE Please refer to your sound card's documentation to determine the type of driver you need to use for surround output.

  4. From the Default Stereo and Front playback device drop-down list, choose the device where your front speakers are connected.

  5. From the Default Rear playback device drop-down list, choose the device where your rear speakers are connected.

  6. From the Default Center and LFE playback device drop-down list, choose the device where your center speaker and subwoofer are connected.

Overriding default device routing

If you've selected a setting other Microsoft Sound Mapper or Direct Sound Surround Mapper from the Audio device type drop-down list, you can override the default device routing at any time.

NOTE Please refer to your sound card's documentation to determine the type of driver you need to use for surround output.

  1. Open the Mixing Console window.

  2. In the I/O control region, click the Output button and choose an output device for the Front channels.

  3. Repeat step 2 for the Rear and Center/LFE channel pairs.

Connect your amplifier and speakers Closed

Using a 5.1-compatible sound card

  • Connect powered speakers to your sound card's outputs as indicated by your sound card's documentation.

or——

  • Connect your sound card's front, rear, and center/subwoofer outputs to the appropriate inputs on a 6-channel amplifier/home theater receiver. Connect front, rear, center, and LFE speakers to the amplifier.

Using a sound card with six outputs

  • Connect powered speakers to your sound card's outputs. The left channel of the Center/LFE pair is the center channel; the right channel is the LFE channel.

or——

  • Connect your sound card's outputs to the appropriate inputs on a 6-channel amplifier/home theater receiver. Connect front, rear, center, and LFE speakers to the amplifier.

NOTE The audio cables you'll need will depend on your specific hardware.

Using three stereo sound cards

  • Connect powered speakers to your sound cards' outputs where you have routed each of the pairs of channels. The left channel of the Center/LFE pair is the center channel; the right channel is the LFE channel.

or——

  • Connect your sound cards' outputs to the appropriate inputs on a 6-channel amplifier/home theater receiver. Connect front, rear, center, and LFE speakers to the amplifier.

Multiple sound card setups may not work with ASIO drivers. You can only use a single ASIO driver at a time, and some ASIO drivers can conflict with other audio driver models (such as WDM and wave drivers).

NOTE The audio cables you'll need will depend on your specific hardware. For a typical application, you'll need three cables: each will have a 3.5 mm stereo plug on one end and dual RCA connectors on the other.
