The new system is built around the CLA406A, a metal braced, birch ply enclosed line array column housing four custom 6.5" (165mm) woofers and a 1.5" (35mm) large format B&C neodymium compression driver with a 2.5" (64mm) voice coil - the combination operating across a frequency range of 65Hz-20kHz. The specially designed waveguide has a horizontal dispersion of 100° and 25° vertical. The height dimension of the waveguide allows excellent vertical control.
Powering the CLA406A is a convection cooled, die-cast aluminium Class-D amplifier module delivering 600 Watts for LF duties and 300Watts for high frequencies. The unit is controlled by a DSP offering eight EQ presets.
Designed for easy portability and rugged reliability, the Vertus CLA604A is equipped with two aluminium handles with rubber inserts and 12 anchor points, which combine to make the system extremely versatile. Via optional hardware it is possible to couple two CLA406A with angles of 0° - 10° - 20°, with the adjacent waveguides set for long range operation, or with one cabinet above the other for short-medium distance applications. Additional accessories are available for system suspension as well as flying a Vertus CLA118SA subwoofer.
