Speaker System Model 380SD, 300SD

GENERAL DESCRIPTION

The 380SD and 300SD are compact, roadworthy 3-way

speaker systems with Thiele-Small aligned bass reflex encl-

osures which house one 15" (380SD) loudspeaker, one 12"

(300SD) loudspeaker and a constant directivity horn cou­pled wi th high efficient compression driver and a high per­formance tweeter. They are designed to be used as full

range systems or with the use of the additional in/out 1/4"
phone jacks can be bi-amplified. They offer extended fre-

quency response, exceptionally high power capacity

(120W continuous pink noise) and high efficiency. They are

ideal for any sound reinforcement application that requires
a blend of outstanding performance and maximum porta­bility. TOA's unique front-slotted design functions as an
acoustic low pass filter, obtaining a smooth crossover be­tween low and high frequency and ensuring flat response.

They are equipped with th e side-mounted handles fo r ease

in carrying and set up. The enclosures have grills to pro­tect loudspeaker and interlocking corners for vertical stack­ing of similar models and an integral stand mounting adap­ter.

FEATURES

1. Extended frequency response

2. High power capacity of 120 watts continuous pink noise
(Test duration: 24 hours)

3. Constant directivity horn gives coverage of 90 degrees
horizontal by 40 degrees vertical

4. Slotted design that functions as an acoustic low pass fil ­ter

5. Easily stackable on similar speakers and mountable on

a speaker stand

6. Side-mounted handles for ease in carrying

7. Input jacks for bi-amplification

Input Panel

Connects to the output of power amplifier. This
is the input jack when used as a full range
speaker.

Connects to the amplifier for high frequency

when driving the speaker system with bi­amplification.

Connects to the amplifier for low frequency
when driving the speaker system with bi-

amplification.

Adjusts the sound level of the mid-frequency.

Make the level setting according to the environ­mental conditions, although almost flat frequen­cy response is obtainable so far as the atte­nuator remains within the "NORMAL" range.

FULL RANGE OUTPUT

Make bridge connection of this output to the full

range input of another speaker system when

driving two speaker systems with one power

amplifier.

BI-AMP OUTPUT (HIGH)

For bridge connection in high frequency to

another speaker.

BI-AMP OUTPUT (LOW)

For bridge connection in low frequency to

another speaker.

CAUTION:
DO NOT USE THE BI-AMP JACKS UNLESS

THE SPEAKER SYSTEM IS DRIVEN UNDER
MULTI-AMPLIFIERED SYSTEM. CONNECTING
THE FULL RANGE OUTPUT TO THE BI-AMP
INPUT JACK MAY DAMAGE THE SPEAKER.
