Station Master - Product Information
| An addition to Sonifex's range
of low cost radio station 'building blocks' is the Station
Master. It is designed to combine all black boxes needed for
audio distribution, studio switching, talkback and monitoring
into a single low cost package that is easy to install.
| Combining all the
black boxes into one leads to significant cost savings over the
discrete parts it replaces without any compromise on quality,
ensuring the maintenance of high engineering standards even when
budgets are tight.
The monitoring of the Station Master is available
using either a built-in amplifier or through a headphone output.
The unit is available with either VU or PPM meters.
Master - the Benefits
The Station Master
has a number of benefits :
- Saves money - combining several features
into one unit gives significant cost savings over purchasing
the discrete parts that Station Master replaces, without any
compromise on quality.
- Easy to install - single unit simplifies
- Requires less space - Station Master is a
3U high 19" single rackmount unit which replaces up to 11U
rackspace that discrete components can occupy.
Master - Studio Switching
| 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 or a
mono feed of the stereo source. The studio switching is achieved
using latching relays and therefore retains its switch status
in the event of power-failure.
Master - Delay Control
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.
Master - Monitoring
Master is fitted with either 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. The audio can be monitored via headphones
or output through a power amp capable of driving 10W into 8W speakers.
There are also two *" jack insert points for using the Station
Master to monitor from a jack-field.
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
Master - Talkback
|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. Individual satellites can talk to each other
or broadcast to all stations.
Master - Audio Distribution
Station Master distributes the 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.
Master - Power Failure
In the event of a power failure to the Station Master, it will
continue to route the current on-air studio to the transmission
and logging outputs. Also, when power is re-applied to the Station
Master, all switching, including the offer and accept switching,
will instantly 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.
