ALTEC, offers a promising approach to design flexibility, in three non-powered speaker
systems, the ALTEC 1201B, 1202B, and 1204A. Most widely used by professional
musicians, these systems provide complete coverage for any requirement.
The ALTEC 1201B Column Speaker System may be used to fill any small alcove or
other area out of the main room. Compact and portable the 1201B provides a system
that is easy to handle, carefully engineered for optimum distribution and smoothness of
response.
Frequency response of the ALTEC 1201B Column Speaker System, is extremely wide,
from 70 to 14,000 Hz. Impedance is rated at 8 ohms, with power handling a very
conservative 50 watts.
The ALTEC 1202B Musical Instrument/Public Address Speaker System is a rugged,
attractiwiy styled speaker system patterned after ALTEC'S famous "The Voice of the
Theatre®" speakers. Featuring an 8 ohm impedance, the 1202B is capable of being
paralleled with another similar system and operated from a 4-ohm amplifier having up to
170 watts of continuous power. The system incorporates a highly efficient, high
frequency speaker and sectoral horn with a large low frequency speaker. Crossover
network of the 1202B is a full section LC type unit with crossover at 800 Hz.
The new ALTEC 1204A Wide Range Speaker System was designed to achieve the
performance required by professional musicians and is capable of being operated from
amplifiers rated at 85 watts continuous power output. Input impedance is 8 ohms and
two systems may be used with a 4-ohm amplifier. The high frequency section is supplied
with a high frequency driver coupled to a sectoral horn embodying a revolutionary new
diaphragm of
' construction.
The crossover network of the 1204A is a full section LC type unit with crossover at 500
Hz, including a switch to vary the high frequency output for control of acoustical output
for varying ambient noise conditions.
All of ALTEC'S Speaker Systems are of plywood construction with vinyl coverings and
vinyl edge bumpers. The 1202B and 1204A are fitted with casters for easy 'roll around'
handling.
Modern techniques in design and engineering is the key to consistent, excellent results,
and at ALTEC, quality standards must be the highest attainable.
