7. g free of distortion will do less damage to the loudspeaker than a lower power amplifier continually clipping It is also worth remembering that a high powered amplifier running at less than 90 of output power generally sounds a lot better than a lower power amplifier running at 100 An amplifier with insufficient drive capability will not allow the full performance of the loudspeaker to be realised It is important when using different manufacturers amplifiers in a single installation that they have very closely matched gains the variation should be less than 0 5dB This precaution is important to the overall system balance when only a single compressor limiter or active crossover is being used with multiple cabinets it is therefore recommended that the same amplifiers be used throughout 6 Voltage and Power Selection Distributed Line Operation When using 70 7V or 100V distributed line systems the transformer can be tapped at 60W 30W and 15W with an extra 7 5W tapping for 70 7V line systems The taps are selected via a rotarv switch as shown in Figure 6a and is located on the front of the unit behind the grille Figure 6b When the relevant voltage tappings have been selected add the individual power in Watts at all speakers and select and amplifier with a rating equal to or exceeding the total power in Watts All of the transformer primaries should be connected in parallel to the output of this amplifier If for example you select
