from the head unit that measures above (+) 5
volts when the unit is on and below (+) 3 volts
when the unit is shut off. This includes power
antennas, amplifi er remote outputs (typically
(+) 12 volts but may be as low as (+) 5 volts in
some OEM systems), or speaker outputs. A high-
powered deck will normally supply between (+)
6-7 volts DC at the speaker output; this is suf-
fi cient to trigger the Remote Power Adapter.
Use this method for applications where the head
unit lacks any dedicated switched outputs or it is
easier to access a speaker terminal.

Note: If the adapter is being triggered by a
speaker output, it will stay on (along with the
devices it controls) for a short period after the
head unit is switched off. This is due to the
stored energy of a typical chip output and can-
not be avoided. To prevent turn-off transient
noise we recommend that the adapter be trig-
gered by a dedicated remote output of the head
unit whenever possible.

By combining two or more adapters, sequen-
