SelecTone® Connector kits which allow the use of SelecTone® speaker or amplifiers (1 Vrms devices) to be used in any public address system (25 or 70 Vrms). Using these connectors and the 25 Vrms output from the 300VSC-1, 300VSC-1044SB, 300SCW-1 or 300MB SelecTone® command center creates a true balanced line system which will filter all extraneous noise from the audio lines. Expanding a centrally amplified public address system often requires the addition of another control amplifier. With the appropriate connector kits and SelecTone® speaker or amplifiers, the system can easily be expanded without the costly addition of a central amplifier. Public address equipment manufacturers do not offer a wide selection of explosion-proof products. Now adding a class I, division 1 or class I, division 2 device to an existing central PA system is simple. Select either a 300X, 300GCX or 302GCX speaker or amplifier and the appropriate connector kit. SelecTone® typically require a minimum of 18-gauge twisted pair, isolated from the AC line. With an AM series connector kit and the 25 Vrms output of the SelecTone® control, a balanced line is created which filters induced line noise. This also allows the installer to use smaller gauge wire without the risk of poor intelligibility. SelecTone® connector kits allow existing public address systems to be expanded with SelecTone® speaker or amplifiers-no additional central amplifier is required.
