ANALOG MPX CODEC MODULE

A separate Input/Output module is available for the APT AoIP MULTI-CHANNEL CODEC which enables the transmission of analog MPX signals in duplex and simplex mode as well as AUX and GPIO signals. The mix of digital and analog MPX transmission on the same frame allows seamless migration from analog MPX processing to digital processing regardless of the transmitter type.

Specific benefits of APT MPX transmission include:

• Dual Simplex Transmission 
  In simplex mode the MPX Codec can send or receive 2x MPX signals
• Redundant IP Transport 
  MPX signals for FM require a highly reliable transport mechanism. With SureStream added to the IP network, the FM link benefits from “always on redundancy” without adding further link latency.
• Overmodulation Cancellation
  A unique feature of the APT MPX Codecs is the cancellation of undesired peaks and drops of the MPX signal in order to reliably prevent overmodulation. Artefacts of this type are caused by lost packets during transmission.
• ScriptEasy enabled on MPX Codecs
  With ScriptEasy, an MPX Codec can autonomously manage backup switching on MPX inputs and perform a wide range of other controls and actions.

SURESTREAM FOR BROADCAST QUALITY AUDIO OVER IP

SureStream technology is a revolutionary innovation from APT that enables broadcasters to use inexpensive IP links and still maintain professional broadcast-grade audio quality and reliability.

It delivers the audio quality and reliability you expect from a T1/E1 link at a fraction of the associated cost. APT SureStream Technology also offers the added benefit of «Always-On Redundancy». With APT SureStream Technology, you can save thousands on your audio transport bills and still offer your listeners the highest quality sound. 

CONNECT WITH WORLDCAST MANAGER

The WorldCast Manager  simplifies the management of all SNMP-enabled devices in a network, providing real-time status, historical data and visualization of multiple devices from a single screen. The intuitive and simple-to-use interface shows all devices located at your site(s) displaying product information, alerting you to any alarms and providing one-click access to the unit’s web-based control interface.

The WorldCast Manager is compatible with all WorldCast Systems’ equipment as well as SNMP devices from ANY manufacturer.

APPLICATIONS

MPX OVER IP 

The APT AoIP Codec Module is also able to support 85kHz or 64kHz  of audio bandwidth and scale the sample rate to 192kHz or 128kHz, enabling a digital MPX signal to be sent on an AES stream. The output of the audio codec can therefore be transferred directly to the modulator of the exciter. This 100% digital path eliminates D/A and A/D conversions which may cause degradation of signal quality and could introduce distortion.

For maximum compatibility with existing analog MPX equipment, the AoIP card provides support for both Analog and Digital MPX transmission. Offering analog-analog, analog-digital and digital-digital MPX distribution all on a single platform provides broadcasters with a solution for their current needs and a clear and affordable migration path for the future.
