Product Overview

The Cloud CXA6 is a versatile and innovative multi channel amplifier. It exhibits low levels of noise and distortion, and utilises the highest quality components, ensuring outstanding sound quality and rugged durability. Plug in VCA modules are available for applications where remote level control is required. Line distribution systems of both 70V and 100V are also catered for with the optional high performance transformer modules.

Applications

Features

The Cloud CX-A6 is a high-quality six-channel power amplifier designed for installed sound reinforcement in commercial, industrial, retail or leisure premises. They are ideal for situations where the various locations of the building require different programme material and/or levels.

Each channel of the CX-A6 will deliver 120 W into a 4 ohm load for long periods of time. Safety features of the design include VI limiting, switch-on delay (2 seconds) and protection against DC offset or thermal overload. It is built in a 2U steel enclosure, and uses variable–speed forced-air cooling. Any two channels may be wired in Bridge Mode, allowing power outputs of double the normal rating to be delivered to a load of 8 ohms (minimum).

In addition to the power switch and associated LED, the front panel is fitted with three LEDs for each channel, confirming signal presence, peak level and activation of the protection circuitry. Rear panel controls are provided for individual channel gain trims and input routing to configure the amplifier in various combinations of mono, stereo or multi-channel operation. The inputs are electronically balanced, on XLR connectors.

The CX-A6 may also be used to drive 100 V/70 V-line loudspeaker systems by the addition of a standard Cloud accessory, the CXL-100T, which is a single channel toroidal transformer module for external mounting. For installation convenience, the CXL-800, a 2U rackmounting assembly which can hold up to eight CXL-100Ts, is also available. To prevent LF transformer saturation in 100 V/70 V-line systems, a 65 Hz high-pass filter may be enabled for each channel individually, by internal jumper.
