Speaker System
Model 380-SE
GENERAL DESCRIPTION
The TOA 380-SE is a 3-way loudspeaker system specifically
developed for the reproduction of electronic music. Analog
and digital keyboard synthesizers, drum machines, and guitar
synths require a speaker system with a wide frequency
response, high power capacity and the ability to handle the
extreme dynamic range these instruments produce. The TOA
380-SE was designed to meet these stringent requirements.
The system consists of a bass reflex enclosure housing a
heavy duty 15-inch woofer, a high-efficiency compression
driver coupled to a constant directivity horn, and an
exponential horn tweeter. The constant directivity horn
ensures a uniform dispersion pattern of 90 degrees horizontal
and 40 degrees vertical, while the tweeter delivers an even
response to 20kHz. This combination results in a smoothness
and clarity that prevents "ear fatigue" even at a high volume
levels. The system is rated at 360 watts continuous program
material.
The rear panel provides ¼" phone jack inputs for full-range,
biamp, triamp operation. All inputs have parallel bridging jacks
for chaining multiple speakers. The mid- and high-frequency
level controls are recessed and located on the side of the
cabinet near the front for convenient operation.
The wooden enclosure is sturdily constructed, and equipped
with large side-mounted handles for easy transport.
Interlocking protective corners allow stacking of multiple
speakers, and the polyester finish resists scratches. A
removable black jersey grillecloth completes the high tech
look of the 380-SE.
FEATURES
1. Extended frequency response for accurate reproduction of
electronic music
2. Power capacity of 360 watts continuous gives wide dynamic
range
3. Constant directivity horn gives coverage of 90 degrees
horizontal by 40 degrees vertical
4. Exponential horn tweeter for clarity smoothness, reduced
"ear fatigue"
5. Level controls recessed and located on side of cabinet for
added convenience.
6. Additional ¼ phone jacks for biamp, triamp, and chaining
7. Rugged enclosure finished in scratch-resistant polyester
with handles, interlocking corners
