Biamplifier
The Altec 1219B—a new standard of performance in clean,
high-level sound reinforcement. The Altec 1224A—a
rugged new biamplifier designed to take road abuse. And
it’s dependable—for continuous hassle-free performance.
The 1219B features our time-proven Voice of the Theatre
type components—a 418 type high-power bass driver in a
bass reflex enclosure, and an 81 IB horn with an 807-8B
driver. The Voice of the Theatre components and systems
have reached a level of fame second only to the performers
who use them, and the 1219B continues this tradition. And
the tough, epoxy-finished cabinet has a removable cover
for portability and protection.
We've tied the components together with our new 1224A^
biamplifier. Super stable and rugged. Low distortion.
Reliability. The result is a high-level powered speaker sys­
tem which is super clean, portable, and dependable. The
biamp concept results in an efficiency of power transfer not
possible in conventional systems. And the 1224A is avail­
able separately for use with other systems you may wish to
convert to the biamp advantage.
New from Altec. The 1219B powered speaker system, and
the 1224A biamplifier.
