8-Channel Monitor Volume Controller User Guide / Owners Manual

Volume 8
Mute
You guessed it ... this switch mutes all speaker outputs. It is particularly
valuable in panic situations, for example, if the computer crashes and its
converters suddenly output uncontrolled high level noise. It is also very useful
in any case where one simply wants silence without changing the Volume
settings—e. g. to answer the telephone.
IMPORTANT: When making any cable connection changes, you should not
only activate the mute switch, but follow the on/off powering procedures
noted on p. 6.
