Description
The Arcam PA720 model is a seven-channel amplifier that belongs to the new proprietary HDA (High Definition Audio) series. The amplifier works in class G, which combines the advantages of class A, associated with high sound quality, and the advantages of class AB, which are characterized by high power and high efficiency.
Such a design allows in real time to satisfy the need of the output stages of the amplifier in the power supply and at the same time spend exactly the amount of electrical energy that is needed at that moment. As a result, it is possible to reduce energy consumption and increase efficiency. For implementation, switching buses are used and, according to the manufacturer, the amplifier works in pure class A up to a power rating of 20 W.
Arcam PA720 circuits are equipped with high-class components, and the power supply unit is equipped with a powerful toroidal transformer. The model consumes a maximum power of one and a half kilowatts and outputs 100 watts for each of the seven channels at a load of 8 ohms, providing high quality sound with excellent detail, and the distortion level of the amplifier tends to zero.
The seven-channel amplifier Arcam PA720 impresses with its laconic monumental design, made in an industrial style. Despite its dimensions, the case has reliable damping.
On its back there are seven input and the same number of output RCA connectors. The unbalanced inputs are duplicated by the same number of balanced XLR inputs, and there is a switch to choose between RCA and XLR connections. The device is equipped with LAN and RS-232 interfaces, which allow the amplifier to be integrated into a home automation system (Crestron, etc.), or into a local network for the purpose of monitoring and IP management. The case has two trigger connectors (input/output) and a USB port, which is used for firmware updates and USB charging of various portable devices. Seven pairs of high-quality terminals are used to connect speakers.
Arcam PA720 will be an ideal solution for working as part of a powerful modern acoustic system or cinema.
