Voltera A Series Amplifiers

The Voltera A Series comprises four half-rack amplifiers with a total power of 300 or 600 watts, delivered by two or four channels in a sleek, compact design. The amplifier channels are extremely flexible in that they can individually be selected to drive either 4 ohm, 8 ohm, 70 V or 100 V, while also supporting power sharing so that up to twice the power can be delivered by any channel. The Voltera A Series is ideal for restaurants, hotels, bars, education, small houses of worship, corporate or other applications where sound distribution or reinforcement is needed. The Voltera 600.2 and 600.4 amplifiers are Energy Star certified, ensuring that these amplifiers consume less power without compromising on their powerful sound distribution and reinforcement capabilities.
