2. GENERAL DESCRIPTION

TOA’s SR-A series Line Array speaker employ unique wave front control technology to create a sound field with high sound clarity and uniform sound pressure. The lineup features types with vertical directivity angles of 5 degrees and 15 degrees, as well as subwoofers. Optional components include the Rigging Frame required for installation and the Tilt Joint Plates that allow stacked speakers to be tilted downward, permitting speaker systems to be customized for a wide variety of permanent installation applications.

3. FEATURES

TOA’s unique wave front control technology permits the linearly arranged speakers to produce a uniform, interference-free high-frequency sound field offering high sound clarity and excellent long distance sound transmission capability.

The SR-A12L(WP) Line Array speaker is a 2-way multi-amplifier driven speaker system featuring a 30 cm high power output woofer and 2 compression drivers. It features 5 degrees of vertical directivity and 90 degrees of horizontal directivity, and is best suited to long-distance sound transmission applications.

The SR-A12S(WP) Line Array speaker is a 2-way multi-amplifier driven speaker system featuring a 30 cm high power output woofer and 2 compression drivers. It features 15 degrees of vertical directivity and 90 degrees of horizontal directivity, and is best suited to short-distance sound transmission applications.

Combining the long-distance SR-A12L(WP) with the short-distance SR-A12S(WP) permits construction of Line Array speaker systems to meet a wide range of applications.

The SR-A18B Subwoofer employs a large-diameter 46 cm woofer unit for high power handling capability, and is designed to be used in conjunction with the SR-A12L or SR-A12S Line Array speakers.

Maintenance can be performed from the rear of the enclosure.

Line Array speakers and sub-woofers can be joined vertically using the supplied Joint Plates. When joined, directivity can be freely adjusted, with overlapping angles between speakers set to between 0 and 5 degrees, in 1-degree units.

The SR-RF12 Rigging Frame permits the Line Array speakers to be arranged in flying or stacked configurations. The SR-A12LWP and SR-A12SWP Line Array speakers can also be installed outdoors in flying configurations using the SR-RF12WP frame.

When stacking Line Array speakers with the Rigging Frame, the downward angle can be increased by up to 10 degrees if the SR-TP12 Tilt Joint Plate is additionally used, allowing more appropriate coverage areas to be set.

The SR-A12LWP and SR-A12SWP are in full conformity with IPX4 Standards, and can be installed outdoors. For outdoor installation conditions, refer to page 17; “Notes on Outdoor Installation” of this manual.
