Multi-Channel Selects

Macros: FrontL, FrontR, Center, LowFreq, BackL, BackR, SideL, SideR

In order for a multi-channel output to be active, it must be selected here. The channel buttons are named:

    Front Left
    Front Right
    Center
    Low Freq
    Back Left
    Back Right
    Side Left
    Side Right

These names are used in Windows documentation and are appropriate for compatibility with "surround sound" installations. But for general-purpose use with Daqarta they may be regarded as arbitrary names for completely interchangeable channels. In particular, there is no special significance to "Low Frequency"; all channels can carry the full bandwidth. Likewise, there is no built-in processing to derive "Center" from normal stereo channels (assuming you have disabled all "special effects" as discussed under Multi-Channel Output Controls).

Note that your sound card may use different names for these channels, like 'Rear' instead of 'Back', or 'Bass' instead of 'Low Freq'. The output jacks usually have stereo connections, so you may just see 'Front', 'Center', 'Rear', and 'Side'. (Center is always paired with the Low Frequency channel.) The jacks may have cryptic abbreviations like 'F-Out', 'SS-Out', 'BS-Out', and 'C/B-Out'.

6-channel (5.1) cards typically use the first 6 channels and omit Side Left and Side Right.

You can verify the channel designations via a simple test using headphones that you plug into each jack in turn, while you change the Channel Select buttons and streams.

Macro Notes:

Macros for the 8 channel selects are FrontL, FrontR, Center, LowFreq, BackL, BackR, SideL, and SideR. To toggle a channel such as Center on, use Center=1. To turn it off, use Center=0, and to toggle to the opposite of the current state use Center=x.
