TYPE A SERIES LINE ARRAY SPEAKER SYSTEM
DESCRIPTION FEATURES

●
Designed for wide bandwidth response
These compact and powerful 2-way modular speaker units
can be used in multiple configurations as required to deliver
greater output power with a more extended frequency
response.
High-performance driver units
Each Type A Series speaker module contains a 30cm (12")
low frequency unit and a high-frequency horn attached to
two compression drivers for greater output.
Wavefront control
The horn incorporates a proprietary phase wavefront
control throat that functions to obtain the best possible
performance from the high frequency drivers.
Adjustable sound coverage
Type A Series provides two speaker configurations
designed for specific coverage characteristics, each having
a different taper. The 5-degree taper is for effectively
transmitting sound over distance while the 15-degree taper
is optimized for excellent short range coverage.
Simple maintenance
Maintenance and servicing are made easier on the Type A
Series to suit it for permanent installations. All driver
replacement is possible from the speaker's rear, a simple
and speedy procedure.
Type A Series line array speakers deliver higher output and
wide bandwidth sound in a compact configuration that can be
combined with other units to provide high-fidelity sound
permanent installation solutions in environments exhibiting
severe acoustic problems. Two Type A Series speakers are
available, SR-A12L designed to transmit sound over
distance with a 5-degree taper, and SR-A12S with a 15-
degree taper optimized for effective short range coverage.
Each configuration incorporates a 30cm (12") low frequency
driver and a high frequency horn with 2 compression high
frequency drivers. A separate subwoofer unit SR-A18B is also
available for low frequency augmentation.

Note:
1. It features the water-protection construction (IPX4), however it is
recommended that it be installed under roofs, eaves, or other locations not
directly exposed to rain or snow.
2. Install the speaker with its air hole down.
3. For outdoor permanent installation, the installation angle of the speaker as
shown at the right must be between 0˚ horizontal and 50˚ downward.
4. When permanently installing the speaker outdoors, inspect it periodically.
