Sonifex SM24-PPM Features
Station Master accepts stereo audio feeds from up to 4 studios, switching them individually to transmission using Offer and Accept operation. The output of the current on-air studio is distributed to the other studios via a dedicated bus, avoiding the need for multiple studio distribution links. The output of the Station Master is provided as a stereo pair and as a mono-feed of the stereo source. The studio switching is achieved using latching relays which retain their switch status if a power-failure occurs.
A profanity delay can be controlled by the Station Master allowing you to install just one delay unit that can be shared by your studios and used by the studio currently on-air.
The Station Master is fitted with a pair of true PPM meters, or VU meters, for monitoring up to 8 stereo sources. These sources consist of the connected studios and four external sources such as news feeds or off air receivers.
Station Master rear view imageThe audio can be monitored via headphones, or output to a power amplifier, or via the internal power amplifier, capable of driving 10W into 8Ω speakers. There are also two ¼” jack insert points on the front panel for using the Station Master to monitor from a jack-field.
Station Master distributes up to 4 incoming stereo signals to each of the connected studios without the need for external distribution amplifiers. These signals, such as off-air receivers, news feeds and outside broadcasts, can be professional balanced inputs or at domestic unbalanced line levels. The gain of the incoming stereo signals can be adjusted from the front panel. Distribution gain is controlled by a preset potentiometer.
The Station Master’s talkback system acts as the master station for talkback with 4 satellite systems. These can either be the connected studios or other locations such as a record library or engineering workshop. Individual satellites can talk to each other or broadcast to all stations.
To allow for logging of broadcasts the Station Master has a stereo balanced output for professional logging equipment, together with 3 sets of phono unbalanced outputs for connection to domestic VCR/DVD equipment.
In the event of a power failure to the Station Master, it will continue to route the current on-air studio to the stereo transmission output. Also, when power is re-applied, all switching, including the Offer and Accept switching, will re-initialise to the configuration when power was lost. This means that your on-air studio can continue transmitting, even if power to the Station Master has failed.
