B-41S Balanced Line Input with Mute-Send
• For Balanced Or Unbalanced Line Level Sources such
as mixer outputs, signal processors and wireless
microphone receivers.
• Transformer Isolation (10 k
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 by Default
(cut diode(s) to
disconnect individual mute bus).
• Tip! Use the B-41S to connect to most modern telephone
system's "Page Output" (usually line level).
• Connector: removable terminal block (B-41S).
Faceplate Controls Mute send sensitivity
PCB Controls Mute bus selection
Input Impedance 10 kohms, 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.
