Connections and Installation Tips
1.
Connect the RED wire to a constant (+) 12 volt
source. This can be the memory wire for the
head unit (check to see if the radio is code-
protected before cutting or unplugging the
memory wire) or the (+) 12 volt battery terminal
of the amplifi er.
2.
Connect the BLACK wire to ground. The radio
chassis or amplifi er ground terminal are gener-
ally good locations for this connection.
3.
The BLUE wire should be connected to the am-
plifi ers or signal processors that are being con-
trolled be the Remote Power Adapter. It supplies
a (+) 12 volt output rated at 1 amp, with a one
to three second delay when triggered by signal
on the GRAY wire.
4.
The GRAY wire may be connected to any wire
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.

6.
The trigger delay is controlled by input volt-
age on the GRAY wire. A low voltage input
will increase the delay to a maximum of three
seconds, at (+) 12 volts the delay drops to about
one second.
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.
7.
By combining two or more adapters, sequen-
tial turn-on of several devices can be achieved.
This will permit a signal processor to power up
after the head unit followed by the amplifi er(s)
thereby preventing turn-on transients in the
signal chain from reaching the speakers.
8.
The Remote Power Adapter will drive up to 1
amp of load at (+) 12 volts. If multiple devices to
be switched exceed the 1 amp limit use a second
adapter. For single-device loads that exceed 1
amp a small relay (DEI part # 8616) can be used.
The Remote Power Adapter is a better way to
switch audio components since it eliminates the
large inductive voltage peaks that a relay gener-
ates.
