N An IR 501 user can mute video and/or audio with a string of IR commands that cannot be duplicated by a computer or
control system sending SIS commands. The switcher sends the following responses:

X%
= Audio gain 0 – 24 (1 dB/step)
X^
= Numeric dB value –18 to +24 (45 steps of gain or attenuation) (Default = 0 dB)
X&
= Audio attenuation 1 – 18 (1 dB/step)
