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

FULL RANGE INPUT

Connects to the output of power amplifier. This is the input

jack when used as a full range speaker system.

MULTI-AMP (3-WAY) INPUTS

Connects to corresponding power amplifiers for high, mid

and low frequency ranges when driving the speaker

system with multi-amp operation.

BI-AMP INPUTS

Connects to corresponding power amplifiers for high/mid

and low frequency ranges when, driving the speaker

system with bi-amp operation.

Level Controls

FULL RANGE OUTPUT

Make bridge connection of this output to the full range

input of another system when driving two speaker

systems with one power amplifier.

MULTI-AMP (3-WAY) OUTPUTS

For bridge connection of multi-amp operation.

BI-AMP OUTPUTS

For bridge connection of bi-amp operation.

CAUTION:

DO NOT USE THE BI-AMP AND MULTI-AMP JACKS

UNLESS THE SPEAKER SYSTEM IS DRIVEN UNDER

Bl- AND MULTI-AMPLIFIERED SYSTEM. CON-

NECTING THE AMPLIFIER OUTPUT FOR THE FULL

RANGE TO THE MULTI- AND BI-AMP INPUT JACKS

MAY DAMAGE THE SPEAKER.

MID FREQUENCY LEVEL CONTROL

HIGH FREQUENCY LEVEL CONTROL

Adjusts the sound level of the mid and high

frequencies when driving the speaker system as a

full range speaker system. Make the level setting

according to the environmental conditions, although

almost flat frequency response is obtainable so far

as the level controls remain within the "NORMAL"

ranges.

Frequency Response (1W/1m:Swept 1/3 OctavePinkNoise)
