Trim j0 2
Channels, pairs or groups can be trimmed with one command. The trim
allows individual channels to be boosted or attenuated by a range of –100dB
to +28dB. This is helpful for quiet audio sources. The adjustment of trim
occurs after the ‘input level’.
To enable ½ dB resolution of the level value, a range of 0 to 255 (0x00 to
0xFF) is used such that 0 gives a –100.0db attenuation, 255 gives a +28dB
gain, it follows therefore that a value of 199 (0xC7) is equivalent to 0dB.
Whilst the large range for trim adjustment exists, it is recommended that only
small values (-6dB to +6dB) are used.
