DS1 micro switch
DS1 micro switch connects controlling circuit ground to main signal
ground. If the M4L’s 9V power supply circuit is fully separated from ground
(isn’t connected with any ground) the DS1 switch should be switched to ON
position.
DS2 micro switch
DS2 micro switch enables/disables the silent switching function. In order
to activate the function that mutes the loops switching clicks the DS2 switch
should be switched to ON position. The DS2 switch should be switched to
OFF position when in the signal path after the M4L there is another device
muting the switching clicks.
Power supply
M4L should be supplied from 9V (DC) external adaptor (efficiency 100 mA
or more). Before plugging the power supply check the pin polarisation. M4L is
protected against opposite polarity (minus as center).
If this protection switches on it is needed to disconnect the power supply and
wait few minutes before reactivation of the device.
ATTANTION!: Damage of the M4L caused by improper power supply causes
the loss of the warranty.
