Niles SPK-1 Auto 12V
600W Triggered 2-CH. Speaker Level A-B Switcher
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 in this manner.
