'Big warm & friendly...'
At right, an early model Yamaha 2002 power
amp. Powerful and warm, these units along with Crowns, Amcrons
and Phase Linears were used in high powered P.A. systems in the
'70s and '80s. Back then there were no dedicated high powered
sound reinforcement amps available like today. The result? - most
big P.A.s in those days tended to sound warmer and more engaging
than they do now because the old muscle amps and horn loaded speakers
sounded good as well as kicking out power. They
were designed by audio engineers who were sound enthusiasts and
music lovers, for studios and well healed audiophiles with big
lounge rooms. With the increasing emphasis on the corporate aspect
these days, there isn't as much sentiment for the idea of a P.A.
system having warmth. Modern P.A. gear is however very cost effective
and professional, and designed to work with standardised connections
such as XLRs and Speakon connectors. The speaker drivers are more
consistent and reliable, and many of the powered speaker systems
are excellent value.
With lightweight switch-mode power supplies,
'D' amplifier modules (see http://www.hypex.nl/)
and high efficiency rare earth magnets in the speaker drivers,
it should be possible to make a high powered system able to be
carried under one arm!
