Page 13: Station Master Introduction
Station Master Introduction Introduction Station Master is an addition to the Sonifex range of professional audio products designed for building radio stations on a budget. It combines all the black boxes required for audio distribution, studio switching, talkback and monitoring for up to 4 studios into a single package. -
Page 14: Monitoring
STATION MASTER INTRODUC TION Monitoring The Station 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 amplifier capable of driving 10W into 8 speakers. -
Page 15: Connectors And Cabling
STATION MASTER INTRODUC TION Connectors and Cabling Many of the problems associated with installing and maintaining studio equipment are due to the use of poor cables or faulty connections. It is recommended that, wherever possible, prewired cables are purchased from recommended manufacturers. If you need bespoke cables making, please ensure that the work is carried out by a qualified engineer. -
Page 16: D-Type Connectors
STATION MASTER INTRODUC TION D-Type Connectors Three different D-Type connectors are used on the Station Master. A 9 pin plug is used for the Delay/Dump Control. A 25 pin plug is used for the Audio I/O and a 25 pin socket for the Control I/O connector. -

TALKBACK INTERCOM INTRODUC TION TB-6D & TB-6R 6 Way Talkback Intercom Overview The TB-6D and TB-6R are used for general talkback between studios and use DC signalling, also known as ground lifting or ground signalling, to communicate with each other. These units can be installed in various locations throughout a studio complex and linked to one another, with each unit being able to talkback to up to 6 others connected together. -
Page 40: Example Application For Tb-6D & Tb-6R
TALKBACK INTERCO M INTRODUC TION For monitoring, you can use either the built-in 1W loudspeaker, or headphones on 6.35mm unbalanced stereo jack. The headphones provide 150mW into 32-600Ω headphones. When the headphones are used, the speaker is automatically muted. Additionally, the monitor speaker can be muted via a remote contact on the 9 pin D-type External Input connector, for example, when used in an area with live microphones. -
