Operation
When the switch is closed,,
a. the signal fed to E-11, X-11, L-11 and B-11 are attenuated by
approx. 60dB. Accordingly a microphone can have a priority at a
time of announcement.
b. the signal fed to H-31 and H-32 are delivered to the amplifier.
(While the switch is opened, the signals are attenuated.)
•
L-41 (with signal activated muting facilities)
When this module accepts the input signal, the mute terminal is
grounded automatically without connection of the remote switch
to the MUTE TERMINAL. It causes the other modules with mute
function, like X-11, to be muted.
Accordingly the signal fed to the L-41 can have a priority.

T-01 SERIES (BALANCED 600-ohm LINE OUTPUT MODULES)
This series of modules, of rated output level 1 volt, is used for
transmitting mixing signals of amplifiers to external equipment and
as a REC
out.
It is provided with a presettable gain control.
T-01 Series should be used exclusively for TOA 900 series, A-903A,
A-906A, A-912A and M-900A. Use it only in Input Port #5 or #6 of
the above models. It will not operate when connected into other
PORTS.
Approx. 5 seconds after power has been supplied to these modules,
the output signal is transmitted.
