INTRODUCTION TO L-09M Model L-09M is designed to deliver high output power up to 300W. This model is equipped with a large sized power meter and a clipping level indicator to permit monitoring of output level. Two pairs of speaker system, A and B, can be connected for selective use according to application. The input circuit is provided with an attenuator so that the speakers can be driven from any type of preamplifier. Because of a high output power amplifier, selected parts are used in the circuits to ensure high reliability. The panel is designed to be mounted on an EIA rack. The panel includes a power switch, LED (pilot lamp), a large sized power meter, a clipping level indicator and a 3-position range selector switch. Selection of speakers is accomplished by a relay, instead of using a rotary switch which is subject to wear of contacts. The model may also be used as a public amplifier because of its high output power (300W). The use of a direct reading watt meter and a clipping indicator enables’monitoring of power. The meter ranges can be selected in 3 steps so that the meter deflects even with a small output. The meter has output ranges for both 4-ohms and 8-ohms.
