PS711 is a power supply which serves as the system master in small,
simple systems. Three separate communications circuits are provided.
These can be linked by silent acting front panel switches in any
combination. Up to 16 headset outstations, or a mix of headset and
loudspeaker stations can be operated. The PS711 is rated to support
these even in the event that the signal lamps on the system are permanently illuminated. The PS711 is protected against short-circuits,
over-temperature and reverse voltages and is designed to survive the
rigours of use in temporary installations.
The PS711 may be chained into a circuit with any other Tecpro
master stations or power supplies to boost the system drive capability
using the BA905 boost adaptor.

The BP111 Headset Outstation is a tough, light-weight remote station suitable for use free standing or hung on the belt or wall. It has been designed to withstand portable use where care is not always taken by the user. The operator has a headphone volume control, mic on-off switch, and a signal light/switch for attracting the attention of other users on the same circuit. A pre-set adjustment is provided for the level of the users voice in his own headphone (sidetone).
connections to the unit are via XLR type connectors, rather than
wired-in leads. This means
that cable failures can be overcome by unplugging the faulty lead or
headset rather than rewiring the box. All connections are on the bottom,
making the unit more comfortable when clipped to the belt.
high bridging impedance of the unit ensures that side-tone and
system sound levels are not altered as outstations are switched on and
off the circuit. The
frequency response of the unit is carefully shaped to provide the
optimum in both intelligibility and long term aural comfort.
requirements: 24/30V DC, 10mA quiescent. 40mA max with Signal lamp on.
output: Suits 8 ohm to 4k ohm headphones.
