Amplifier Considerations
Turbosound NuQ series 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 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 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.
