When I turn on the KPA into tuner mode, it makes sense to me that all output should be muted. While the main and monitor outputs are muted, the SPDIF is not (on my KPA at least)
Even if my SPDIF output level is set to zero, I get an output signal while the KPA is booting up until the tuner appears, then it mutes.
This can create some serious unwanted noise in a studio environment where the KPA is master and the SPDIF is used to monitor/record.
Or perhaps there is a reason why this can't be done?
Thanks for a great product!
