11 Upgrade Ideas for Operators

Emergency Management Operators
Sterling Heights, MI

1 HQ5.1 TIS Audio Processor  
Audio Bandwidth Upgrade
Give your station a more natural sound.
Add a 5000 Hz audio bandwidth filter or processor to your system’s audio chain to make broadcast quality more natural – like conventional broadcasters.

This is an upgrade usually performed in conjunction with the addition of a high quality IP76 Digital Message Player and Professional Recording Services (listed below).

If your system was installed after 2015, you already have 5000 Hz bandwidth capability built in.
See details about the HQ5.1 Broadcast Quality Audio Processor.
See also the HQ5.0 Audio Filter webpage.
2 IP76 Digital Message Player  
IP76 Digital Message Player
Add convenience, quality and network connectivity.
Connect an IP76 Digital Message Player to deliver incredible audio quality to your listeners. Control it by network / IP or by flash drive / USB.

Merely slide in a flash drive with the appropriate MP3 files, and the IP76 system will repeat them automatically for broadcast. When connected to your network it serves up a control page you may browse to when you want to change your message program. Maintain a message library on your PC or laptop from which you can edit, transfer and store audio files conveniently. Optional message management, playlist and text-to-speech software allow you to create and process your audio files to increase quality and intelligibility.

The IP76 Digital Message Player may be added to most information radio stations, while retaining telephone call-in capability as an override / redundancy.

Workstation Audio Control
Use One-Stroke Message Processing
Since 2005, we have offered an option called Workstation Audio Control to accomplish on-screen drag-and-drop message control and have upgraded this popular option to operate on Windows 7 with key features customers have requested. Version 2.1:
  • Message scheduling by date, day and time.
  • Text-to-speech software.
  • Remote program control.
  • Integrated live broadcast.
  • More intuitive on-screen controls, look and feel.

Broadcast Text-Based Notifications to Reach More People
How can you utilize your existing text-based emergency notification system to inform area motorists and patrons who are not in a position to receive text and email? Indeed, how do you reach out to the larger community – those not registered to receive your emergency alert messages – to tell them to take action?

This is ENcast’s unique mission.

ENcast is a means of linking an existing text-based notification system, via Information Radio technology, to populations not previously accessible. All in one motion.

ENcast Technology may be part of any Information Radio Station – new or existing – transforming it into an avenue to reach the unregistered and motorists in transit; a conduit for critical information in a crisis.

 NX8R Digital Message Player
Add Telco redundancy and maximize phone-based broadcast programming.
A digital message player controlled by telephone (and locally) is an important redundancy on information radio stations that are used for emergencies. It can also be the primary means of program management for stations that only have telephone line connectivity. The NX8R Digital Message Player provide the means to those ends. As an upgrade to an existing player, it works on the same convenient protocols as earlier the IP8 or AP55 Digital Message Players with a quantum-leap in performance:

3 hours of recording time and up to 1,000 messages. (The legacy AP55 Player has 14 minutes and 250 messages, maximum.)


Flash memory means all programming is safe from power loss.

A 16-bit recording rate makes messages sound better.


NX8R can handle two live feeds from sources such as NOAA, PCs, CATV, etc.

Station ID

The station identification plays automatically every half-hour as required by the FCC.


If you lose your telephone lines in an emergency, NX8R offers control by VHF radio.
