(6) Microphone Announcements [BA-806 and BA-823]
Connect a microphone to the microphone input terminal located on the rear panel.
Set the power switch to ON, and confirm that the power indicator lights.
Adjust the microphone volume control.
Making an announcement during tape play triggers an internal microphone-activated muting circuit, and the
tape output volume automatically decreases by approximately 20dB. The tape volume automatically returns to
a previous level after announcement completion. For the microphone-activated muting circuit, refer to Item
below.
[Cautions]
(1)Make sure to set this control to zero when no microphone is connected to the BA-806 or BA-823.
(2)Be sure to set the microphone switch to OFF after announcement completion, because the muting circuit is
activated by ambient noise if the switch is left ON.
(7) Microphone-Activated Muting Circuit [BA-806 and BA-823]
The microphone and AUX 2 inputs are provided with the muting circuit which automatically reduces the tape
output volume and AUX 1 volume by approximately 20dB when a microphone announcement is made through such
inputs. The tape output volume gradually returns to its original level after the announcement is completed.
[Note]: The microphone-activated muting circuit does not work when the microphone volume control is set to
minimum position.
(8) Signal and Peak Indicators [BA-806 and BA-823]
During tape play or microphone announcement, see to it that the peak indicator (red) does not light. If it lights, this
indicates that the output is distorted and so, turn down the volume.
The signal indicator (green) lights when a signal is output to the speaker. Check amplifier operation with this
indicator.
