MAXIMUM POWER: Normal Orchestral Material

High energy peaks normal to orchestral music are easily and faithfully reproduced by the XR 5.
These peaks are of relatively short duration and do not produce the heating effect caused by
sustained tone operation. The XR 5 can be driven with an amplifier having up to 200 watts
capacity provided the amplifier is not driven into clipping.

MAXIMUM POWER: Sine Wave

Some music has unusual frequency content. This can be found in some Rock recordings of sus-
tained guitar notes and electronically synthesized tones which have near sine wave properties.
Various kinds of Test records and audio oscillators are also in this category. Avoid driving

the XR 5 with sustained sine wave type signals at power levels greater than limits indicated
below.
