How to Operate NX8R

What May Be Broadcast

Audio Control Methods Comparison among Our Radio Systems

Designed for our fixed and portable Information Radio Systems, the NX8R Digital Message Player allows operators to record up to 1,000 broadcast messages and store three hours of recordings in nonvolatile flash memory. This means, no message (battery) backup is required. Additionally, NX8R provides eight external contacts to initiate various message playlists, live audio segments and event sequences.

NX8R is a direct upgrade to our earlier RAM-based digital message players (AP55 and IP8) with similar protocols and command sets, so relearning protocols is kept to a minimum for existing operators.

Features listed in green below are exclusive to the NX8R Digital Message Player compared to any others on the market.
Standard Features Optional Feature
  • Voicemail-style natural voice operation with 800-word/phrase capability; voice prompts and status report on available recording time, sequences, security codes, programming parameters and complete status of current audio program, relay states, power.
  • Identical remote and local control codes.
  • High quality (16-bit sampling rate) recording process, yielding 5500-Hz dynamic range.
  • One thousand independent broadcast messages that may be of any length. Each message may be independently monitored and later erased, as desired.
  • Automatic message scheduling by time, day, date. Internal time clock never requires setting, keeping time even with total loss of power.
  • Fifty message playlists that may contain hundreds of broadcast messages, commands for up to four external relays, other (nested) playlists and differing output levels for each audio output. Playlists may be created, recreated or appended locally or remotely.
  • Selection of active playlist locally or remotely.
  • Three hours of recordable time in dynamic flash memory.
  • Three audio inputs for separate and independent live program feeds, each with independent audio level controls.
  • Three audio outputs with audio levels settable locally, remotely or programmed to change automatically.
  • One- to nine-digit security access code, defeat-able phone prompting, programmable locally or remotely. User-settable number of retries and timeout period for maximum security.
  • Five-second and full-message survey monitoring of all stored messages and playlists.
  • Eight prioritized control closures to trigger message sequences remotely.
  • Control closure prioritization allows automatic interrupts for emergency messages and automatic National Weather Service all-hazard radio notifications (weather and EAS).
  • Includes prerecorded messages by professional announcer for advisory radio application -- ready for broadcast immediately.
  • Station identification message broadcasts every half-hour.
  • Rack mountable, slim design, 1 RU in height.
