Niles SPK1 Speaker Level A-B Switcher 12V-Triggered

The Niles SPK-1 Speaker-Level A-B Switcher 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. Please Note: This unit is not a Signal-Sensing Switcher; if signal-sensing is required use the SAS-1 or ABS-1, each sold separately.
