/* Maximum number of analogue outputs */
The values loaded into the mixer are 16-bit values, with 8192 representing 0dB, going up to a current maximum of 16345 (+6dB). All supported interfaces have no problem going up to 32612 (+12dB), so update SCARLETT2_MIXER_MAX_DB and scarlett2_mixer_values[] to allow for this. Tested with: - Scarlett 2nd Gen 6i6, 18i8, 18i20 - Scarlett 3rd Gen 4i4, 8i6, 18i8, 18i20 - Scarlett 4th Gen Solo, 2i2, 4i4 - Clarett+ 2Pre, 4Pre, 8Pre - Vocaster One and Two Signed-off-by: Geoffrey D.
