DESCRIPTION
The Shure Model VA300 Vocal Master Sound System con-
sists of one Control Console (VA300-C) and two Speaker

Columns (VA300-S).
VA300 Vocal Master Sound System provides the required
portability, flexibility, and dependability demanded by profes-
sional entertainers.
The VA300-C mixer/power amplifier Console permits the
user to mix up to six microphones with individual control over
volume, tone and reverberation. A solid-state 100 watt R.M.S.
power amplifier is incorporated in the Console. Unique cir-
cuitry design protects the solid-state components against dam-
age as a possible result of open-circuit or short-circuit condi-
tions of the amplifier outputs. The output transistors are also
protected against overheating by the use of automatic thermal
sensors. All components of the VA300 Vocal Master Sound
System are conservatively rated and are operated well within
their respective tolerances to assure long life and trouble-free
The VA300-C is Underwriters Laboratories, Inc. listed, and is
listed by the CSA Testing laboratories as certified.
performance.
The VA300-S Speaker Columns are highly directional, wide
range, line-radiators. A rear-ported enclosure is utilized which
contributes to the directional characteristics of the Speaker
Column and is crucial in reduction of feedback.
The VA300-S employs four special 8-inch loudspeakers and
two special 10-inch loudspeakers providing a total cone area of
2,310 cm² (358 in²).
Each Speaker Column is furnished with a 15m (50 ft) #18
gauge, 2-conductor rubber jacketed cable with locking phone
plugs attached.
