Avoid operating the speaker system with sustained sine wave signals at power levels
greater than the indicated limits. Permanent damage may result.

POWER HANDLING: Program Material

High energy peaks normal to orchestral music are easily and faithfully reproduced
by the speaker system. These peaks are of relatively short duration and do not
produce the heating effect caused by sustained tone operation. The ML-H Speaker
system will handle up to 300 watts of orchestral music program material. Care
must be taken, however, to use a power amplifier that has an adequate power rating.
If a low power amplifier is used, the loudest passages may be clippedH by the
amplifier. This clipping will cause the speaker to sound distorted. The large
harmonic content of a badly clipped signal can cause excessive heating and re-
sulting damage to the high frequency speaker elements and crossover network.

OUTPUT LEVEL

In a reverberant room the system will nominally produce an 89dB sound pressure
level when driven at a one watt level referred to 8m.
