System Requirements
TCS series 2-way enclosures are passive loudspeaker systems. This means that they
require only one amplifier channel for correct operation, the frequency splitting between
the low frequency driver and the high frequency driver being accomplished by the
internal passive crossover network in each enclosure. If subwoofer enclosures are used in
a bi-amplified system in conjunction with TCS series 2-way enclosures, additional
amplifier channels and external electronic crossovers will be required. Turbosound LMS
series digital management systems are recommended for this purpose.
Amplifier considerations
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.
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
therefore 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.
In general, the more powerful the amplifier the better it will sound, provided that it is not
driven into sustained clipping. 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.
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.
