The Cloud VA2120 and VA4120 are cost-effective audio power amplifiers for use in all types of commercial premises. They have been designed to be as simple to install and operate as possible.
The two models are identical in terms of facilities, and differ only in the number of channels: two (VA2120) or four (VA4120). Each channel can deliver 120 W. The amplifiers can drive either lowimpedance loudspeakers directly (4 ohms minimum) or 25/70/100 V-line loudspeaker distribution systems.
The amplifiers incorporate a limiter in each channel to protect the output stage and connected loudspeakers: this reduces excessive signal levels to ensure that clipping does not occur. Further protection circuitry disconnects the output if the maximum permitted internal temperature is exceeded, or if DC is detected at the output terminals.
All connections and controls are on the rear panel. Each channel has a preset level control and a switchable high-pass filter to mitigate the effect of transformer saturation at low frequencies when driving 25/70/100 V-line systems.
The front panel has a set of LEDs for each channel, confirming signal presence, excessive level and amplifier protection activity. Both models are forced-air cooled by fans mounted on the rear panel.
