Pre-Recorded Announcements from the MCC7500 console ?

Postby 15LocutorMTC » Fri Dec 18, 2015 5:28 am

Good Morning.

I am being asked to record some pre-recorded dispatch announcement to be transmitted from an MCC 7500 Console.
The dispatchers may want to record these canned announcement on the fly as per event.

How can I accomplish this for them ??

Well one option is maybe use the external paging input with some kind of device. I do not think there is something built into the console.

Thanks for the info on the external paging input.

Any data or wiring info/diagram for external paging input ?

Would 4K deviated audio be re-transmitted from the console if input through this paging port ?
How to I get the console to key?
Ground the mic?
or
Is there a TX Voltage or TX tone needed.

I was thinking of coming from a digital audio recorder into the desk mic input.

Any thoughts

From the VPM manual:

"External Paging Encoder Port
The external paging encoder port allows an external tone paging encoder to be used with a dispatch console to provide tone paging services. The dispatch console transmits the paging tones generated by the encoder on the selected conventional radio resource or resources. If a dispatcher wants to send paging tones on an ASTRO® 25 Conventional channel, an external paging encoder is required. This feature has an RJ45 connector with an analog 600 Ohm audio input to which the paging tones are applied. A paging push-to-talk (PTT) input enables a dry contact closure to be applied that indicates when the dispatch console should transmit the tones on the radio channel or channels. When the dispatch console sees the paging PTT input go active, it transmits the audio appearing at the audio input on the selected conventional channel(s). If PL Stripping is enabled on a conventional channel, the PL is stripped when the paging tones are transmitted. No de-emphasis filtering is performed and no talk extend is provided with externally generated tones. Generally, the external paging encoder provides these functions."

If your system is running software release A7.15 or later you can load up to 15 canned audio files and assign them to Alert Tone buttons.

This also works on 7.14 architecture. I had some fun with it during build-out of our system... Minions, Beavis shouting WAKE UP HONKY... fun times.
