T-12S Unbalanced Line Input with Music-On-Hold Output & Input Mute-Receive
• Unbalanced Line Input for for AM/FM tuners, cassette
decks, CD players, computer sound cards, jukeboxes,
mixers and satellite receivers.
• Balanced, Uninterrupted Output Of Module's Input
Signal
, transformer-isolated for feeding remote equipment
such as a telephone system's Music-On-Hold input.
• Output Gain Control for adjusting the MOH output signal
level, eliminating the need for an external 1 Watt MOH
amplifier.
• Responds To Mute Bus Activation , via Mute SEND
module or switch-closure.
• Responds To Both Mute Bus # 1 And Mute Bus # 2 By
Default
(cut jumper(s) to disconnect individual mute bus).
• Tip! You can pair the T-12S with the B-41S Mute-Send
module for telephone paging, mutable music input, and
uninterrupted MOH output, all with only two modules.
• Connector: screw terminal (T-12S).
Faceplate Controls Input gain, output gain
PCB Controls Mute bus selection
Input Impedance 220 kohms, unbalanced
Slave Output: Balanced transformer-isolated, drives
