AMPLIFIER CONSIDERATIONS
Turbosound speaker enclosures should be driven by high quality power
amplifiers designed for 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.

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 specified ratings.
LOUDSPEAKER CONNECTIONS
The Impact 50 is provided with a recessed connector panel housing a pair of
colour-coded, spring-loaded push terminals. These are used for input and loop-
out connections to further Impact 50 enclosures. Note that looping out to
additional enclosures has the effect of reducing the total load impedance on the
amplifier. For example, two 16 ohm cabinets in parallel give a combined total
impedance of 8 ohms. It is possible to connect four Impact 50 cabinets in
parallel to one amplifier channel, providing that amplifier is capable of
delivering long term power output into 4 ohms. Never connect loudspeakers to
a power amplifier whose total combined impedance is lower than the amplifier’s
recommended minimum load impedance.
