The basic amplifier is an economical alternative to

 conventional Praesideo power amplifiers and is suitable for applications where built-in digital signal processing functions such as equalizer, delay and AVC are not required. None of them has a Praesideo network interface. They are connected to the Praesideo network through the prs-16mci multi-channel interface that provides audio signals and has full control over them. They are available in four versions: PRS ￣ 1b500 (1 x 500 W), PRS ￣ 2b250 (2 x 250 W), PRS ￣ 4b125 (4 x 125 w), and PRS ￣ 8b060 (8 x 60 W). The basic amplifier is fully monitored and fault events are reported to the Praesideo network controller via a multi-channel interface. The basic amplifier provides connections for group A and group B speakers that are independent of each other in each area, and supports class a speaker loop routing. These devices shall be installed in 19 inch cabinets using the attached mounting brackets. The annotated model suffix (- EU, - CN...) indicates the region specific version of these amplifiers. Amplifiers are identical, only certification, power cord and country of origin will vary. Basic function amplifier PRS ￣ 1b500 is a single channel 500 W device; PRS ￣ 2b250 is a dual channel amplifier, each channel is 250 W; PRS ￣ 4b125 is a four channel amplifier, each channel is 125 W; PRS ￣ 8b060 is an eight channel amplifier, each channel is 60 W. These devices use a low starting current switching power supply and can operate on a 48 V backup battery power supply. Connecting these amplifiers is equipped with a built-in output transformer for driving 70 V and 100 V loudspeakers. They have independent overload protection group A and group B speaker connections that support class a loop wiring. Users can configure group A and group B speakers independently of each other for redundancy. These devices are connected to the prs-16mci multi-channel interface for audio, control and monitoring, but can also operate independently. Audio these amplifiers have analog audio line inputs for low priority local audio. Network audio from the multi-channel interface has a higher priority than local audio. Safety these devices can use AC power and 48 V emergency battery power supply, and can automatically switch between the two. They monitor the two sources and themselves. When used with prs-16mci multichannel interface, they can also monitor speakers and their circuits. Complete channel separation allows one channel of the amplifier to be used as a backup amplifier for the other amplifier channel.
