Multi Room Audio Broad Cast Inputs

I assume the Cbus telephone interface output has enough level to trigger the Multi room audio Broadcast Inputs ??

Thinking of door bell wav file being played when the saturn Door bell switch is pressed !

Door bell through MRA

A door bell wave file in the CBTI works quite nicely.

The high priority input of the matrix switcher was designed to work with the CBTI. The high priority input waits for a signal that exceeds ~400mV for 500mS. This switches all amplifiers to high priority at the volume level that is set in the MARPA software. Once the signal on the high priority line has dropped to 0v for 5 seconds the systems resumes normal operation.

Using the priority inputs consume source 4, meaning that the number of analogue sources is reduced.

Does that mean the Doorbell WAV need to have some padding on the front.

If the wav files was "Ding Dong" would you only hear "DONG" because of the setup time to detect sound, switch on the amps etc.

You can not pad with silence either at the front as this will not trigger.
Need to be "Dong ding dong" may be....

The priority input consuming input 4 is a gotcha Was this in the doco ?? I read it all and could not see it.

if something was playing on input 4 would it mix the sources ??

Is is this the same on the other NON priority input ?

High priority response

1. If the amplifier is on at the time you will hear the ?ding dong?.
2. An amplifier will take a little longer to respond to a high priority signal if it is off. The amplifier must first turn on before any signals can be heard. This can work in your favor when using a typical ?ding dong? doorbell sound. The result will be that if the amplifier is off when the doorbell is triggered you will most likely hear the ?dong? noise only. This may be preferred if the amplifier is off due to someone wanting a quite area.

There is also an option in each of the amplifiers to stop them from responding to high priority signals when they are turned off.

I can?t quote any response times for amplifiers responding to high priority signals because it ultimately comes down to the signal that it being fed into the terminal. If you do pad the signal it will have to be with a signal with a high enough level to trigger the high priority,

You are correct, the source is not consumed but mixed with the high priority and low priority signals. This is only the case for source 4 and not for any other sources.

The addition of an Single Audio Distributor (560011) being feed into the Digital Input on the Matrix Unit will allow another source to be added.

This would mean you get that input back if required.
