U-13
U-13 Series Unbalanced Line Input with High/Low Cut Filters and Mute-Receive
U-12S Unbalanced Line Input with Variable Mute-Receive Depth
• For Unbalanced, Line Level Sources such as AM/FM
tuners, cassette decks, CD players, computer sound cards,
jukeboxes, mixers and satellite receivers.
• Use For Adjacent Sources (less than 15 feet from the
host unit).
• High and Low Cut Filters for tone control, 4.2 kHz and
330 Hz, 6 dB/octave.
• 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).
• Connectors: dual RCA jacks w/ passive summing (U-13R),
removable terminal block (U-13S).
Faceplate Controls Gain, high & low cut filters
PCB Controls Mute bus selection
Input Impedance 220 kohms, unbalanced
