TOA Electronics U-13R - Unbalanced Line Input Module with High/Low Cut Filters and Mute-Receive for 900 Series (Dual RCA) - Manual (Page 16)

• For Applications Requiring 600 Ohm Line Matching.
• Transformer Isolation (600
Ω
) minimizes ground loop
problems when connecting remote equipment (greater than
15 feet).
• Signal At Input Terminals Activates Both Mute Bus #
1 and Mute Bus # 2 Buses by Default
(cut diode(s) to
disconnect individual mute bus).
• Connector: removable terminal block (L-41S).
Faceplate Controls Mute send sensitivity
PCB Controls Mute bus selection
Input Impedance 600 ohms, balanced transformer-isolated
Sensitivity -16 dBu, min. -34 dBu to activate mute
function
Gain -2 dB

* For unbalanced sources, use a shielded, twisted pair and
connect the output to Hot and Common (inner conductors).
Connect the shield to Earth at the module and leave
unterminated (floating) at the source.
