INTRODUCTION
The SPK-1 is a two channel, speaker level A-B switch. The SPK-1 can be used to switch amplifiers,
speakers, surround sound systems, or any application where a voltage-activated speaker-level switch
is preferred.
Applying 12 volts DC to the control input connector activates the switch. A control output connector
is also provided. The control output is internally connected in parallel with the SPK-1’s control input.
The control output can be used to control additional SPK-1’s by “daisy-chaining” the control output of
one unit to the control input of the next. Connecting two SPK-1’s together enables you to switch four
channels of speaker-level signals and connecting three units together lets you switch six channels,
and so on. A maximum of 6 SPK-1’s may be connected together in this manner.
The control output can also be used to connect other Niles switching devices such as the AC-3
Voltage Activated AC outlet and the AVS-2 Voltage Activated Line-Level Switch.
The SPK-1 is designed primarily to be used as an expansion unit for the Niles SAS-1 Signal Activated
A-B Switch. The SAS-1 is an automatic A-B switch designed to replace manually operated A-B
switches. It automatically switches from A to B when a signal is present at input B. The SAS-1 can
switch any combination of line-level audio, speaker-level audio and composite video signals. Using its
control out connector, the SAS-1 can be used as the “master” unit which activates other “slave” units
such as the SPK-1, AVS-2 and AC-3. Please refer to www.nilesaudio.com for more information on
these and other Niles switching systems available.

INSTALLATION
CONNECTIONS
Refer to figures 1 through 3 on the following pages.
Strip approximately 1/4" – NO MORE – of insulation from each wire. Twist the free ends of each
wire tightly together and insert them into the appropriate holes in the binding posts. Secure by
turning the binding posts until they are hand-tight. BE SURE TO OBSERVE PROPER PHASING –
connect the positive terminals of the amplifier(s) and speakers to the positive terminals of the
SPK-1 and connect the negative terminals of the amplifier(s) and speakers to the negative
terminals of the SPK-1.
Connect the 12 volt DC source which will activate the SPK-1 to the “CONTROL IN” connector. An
optional DC adapter is available from Niles Audio. BE SURE TO OBSERVE PROPER POLARITY WHEN
MAKING THIS CONNECTION.
Any other switching devices to be activated at the same time may be “daisy chained” together by
using the “CONTROL OUT” connector.
