TOA Electronics U-13R - Unbalanced Line Input Module with High/Low Cut Filters and Mute-Receive for 900 Series (Dual RCA) - Manual (Page 29)

APPLICATIONS PAGE 30
Paging Over a Music Source
1. Connect the Telephone Page output to a B-41S
(Balanced Line Input with Mute-Send) module or,
for Microphone Paging, use an M-41S (Microphone
Input with Mute-Send) module.
2. Connect the Music Source to a U-13R (Unbalanced
Line Input with Mute-Receive) module.
3. Adjust the mute threshold as necessary with the
Sensitivity control (located on the mute-send
module's circuit board). If the paging audio falls
below the mute threshold for greater than
approximately two seconds, the music will resume.
Since mute-type modules connect to both Mute Bus #1
and #2 by default, no jumper configuration is required.
Telephone Paging and Music-On-Hold
1. Connect the Telephone Page output to a B-41S
(Balanced Line Input with Mute-Send) module.
2. Connect the Music Source to a T-12S (Unbalanced
Line Input with Music-On-Hold Output) module's
input.
3. Connect the T-12S module's output to the
telephone system's Music-On-Hold input.
4. Adjust the output signal level with the T-12S front
panel Output Gain control.
Since mute-type modules connect to both Mute Bus #1
and #2 by default, no jumper configuration is required.
Banquet Room Sound System
Banquet room sound systems usually include a podium
microphone and a music source. Since there will be a
variety of presenters, the signal level present at the
microphone will vary. The music volume level will also
need to be remote controlled from the podium.
Because the microphone level will not be continuous,
Switch Closure Muting will be necessary to ensure that
the music remains off until after the presentation.
1. Connect the Podium Microphone to an M-61S
(Microphone Input with Compressor).
2. Connect the Music Source output to a U-21S
(Unbalanced Input with Remote Volume Control).
3. Connect a 10 k
Ω
linear-taper potentiometer to
screw terminals 4 and 5 of the U-21S.
4. Connect a switch (normally-open) between screw
terminals 4 and 5 of the U-21S.
(pins #4 and 5, U-21S)
APPLICATIONS
5. Set the M-61S Threshold control according to the
highest potential signal at the microphone.
Closing the switch mutes the music, opening the
switch allows the music to resume.
