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.
