The Shure Model
VA302 Vocal Master Sound System
consists of one Control Console (VA302-C) and two
Speaker Columns (VA300-S).
The Shure Model
VA302E Vocal Master Sound System
consists of one Control Console
(VA302E-C) and two
Speaker Columns (VA300-S).
The Shure Model
VA302E6 Vocal Master Sound System
consists of one Control Console
(VA302E6-C) and two
Speaker Columns (VA300-S).
Designed specifically for the performing vocalist, the
Vocal Master Sound System provides the required porta-
bility, flexibility, and dependability demanded by profes-
sional entertainers.
The
mixerlpower amplifier Control 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 circuitry design protects the solid-state compo-
nents against damage as a possible result of open-circuit
or short-circuit conditions of the amplifier outputs. The
output transistors are also protected against overheating
by the use of automatic thermal sensors. All components
of the Vocal Master Sound System are conservatively rated
and are operated well within their respective tolerances to
assure long life and trouble-free performance.
The VA302-C is Underwriters' Laboratories, Inc. listed,
and is listed by the CSA Testing Laboratories as certified.
The VA300-S Speaker Columns are highly directional,
wide range, line-radiators. A rear-ported enclosure is uti-
lized which contributes to the directional characteristics of
the Speaker Column and is crucial in reduction of feed-
back.
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), #I8
gauge, 2-conductor rubber jacketed cable with locking
phone plugs attached.
