Each of the
MSB-1
features operates independently, so any or all of them can be use or not used. Listed below is how each
of the features operates.
1.
MIC AUDIO OUT is a line level audio output of the audio picked up by the
MSB-1
’s internal microphone. The output level
(or sensitivity of the microphone), can be adjusted with the volume control labeled “MIC” as shown on the Features
Overview page.
2.
AUDIO IN is a line level input that is amplified with an on-board 2 watt amplifier to drive the
MSB-1
’s internal speaker.
The speaker volume can be adjusted with the volume control labeled “SPEAKER” as shown on the Features Overview
page.
3.
AUX SPEAKER is an additional speaker output, driven from the same 2 watt internal amplifier, that can drive up to an
additional three 8 ohm speakers. Viking models 30AE and 35AE ceiling speakers can be used for indoor applications, and
the Viking model 25AE paging horn can be used for outdoor, factory, or warehouse environments.
4.
PUSH BUTTON is a normally open set of contacts that momentarily close when the front paneled “Call” button is pressed.
5.
LED CONTROL is a normally open input that will turn off the front panel blue LED light when a contact closure is pro-
vided.
