System Considerations
Amplifier Requirements
Turbosound loudspeaker enclosures should be driven by high quality power amplifiers
designed for true professional use. Such amplifiers will have balanced inputs, DC and RF
fault protection, and well designed cooling systems for reliability.
For low impedance systems the ‘program’ power, listed in the loudspeaker’s technical
specification, is the best guide to the size of amplifier required for general purpose
applications. The amplifier should be capable of delivering long term broadband power
equal to the loudspeaker’s program power rating at the loudspeaker’s stated nominal
impedance. This approach allows sufficient headroom to generate good dynamic range.
RECOMMENDED AMPLIFIER POWER RATINGS:
The amplifier's rated r.m.s. continuous power output (20Hz – 20kHz, per
channel) should be equal to the program power handling of the
loudspeaker at its nominal impedance.
It should be understood that overdriving an insufficiently powered amplifier is more likely
to cause loudspeaker damage – the total energy in a heavily clipped signal is far higher
than in an unclipped signal – than operating a more powerful amplifier within its ratings.
In general, the more powerful the amplifier the better it will sound, provided that it is not
also driven into sustained clipping.
All the equipment in the system before the system controller should be set up for 0dBV
(775mV) maximum output. One controller can be used to feed several amplifiers as long
as all the amplifiers are the same (or have the same gain ratings). More than one
controller may be required if the amplifiers are of different gain or type. Please contact
your dealer if you require help in this area.
In a distributed system the amplifiers must be capable of supplying broadband power
equivalent to the sum of the power rating of the loudspeakers (taking into account the
individual power taps selected) connected to that particular amplifier channel.
Turbosound recommends the T-series amplifiers for use with the TCS Compact series
system.
