Town Hall Complex
PAS have recently completed the supply and installation of a large emergency PA system to a very busy and highly occupied local authority headquarters in the City of London.
The wireless microphone tuners rely on Phased Lock Loop
(PLL) synthesis for excellent performance levels, stability and
reliability. Oscillation frequency changes caused by changes in
ambient temperature are kept to a minimum. For a dramatic
reduction in noise during changeover between antennas, true
diversity and space diversity are now employed.
The two true diversity
tuner models are equipped with a twin antenna and
support condenser microphones. A channel search function is
incorporated in all tuners, and a two-line LCD display enables
faster meter reading. Remaining battery power indication is also
provided.
