3 Product introduction
The PRM-4P600 is a 600W power amplifier with powerTANK technology that flexibly delivers
the total power over its 4 channels.
The amplifier is ideally suited to background music and clear voice announcement applications
such as:
– Supermarkets
– Bars and restaurants
– Retail outlets
– Education
– Houses of worship
– Museums and galleries
– Transport hubs
– Conference centers
3.1 Features and functions
– 4‑channel amplifier, with a total powerTANK capacity of 600W
powerTANK is a reservoir of available amplification power that is deployed flexibly across the
4 channels of the amplifier. There is no need to set up the powerTANK as it adapts to the
requirements of each zone or output without extra manual configuration of each individual
channel.
– dualCOOL convection cooling with additional intelligent fan in case of extreme thermal
conditions
The dualCOOL thermal design means that the amplifier typically operates as a convection
cooled amplifier, but in extreme thermal conditions the amplifier is also equipped with an
intelligent multi‑speed fan to ensure maximum performance and reliability in any application.
– ecoRAIL and APD deliver significant reduction in power consumption
ecoRAIL’s power consumption is similar to a regular standby level, yet ecoRAIL still produces
audio output suitable for background music levels, and the Auto Power Down (APD) mode can
be engaged to further reduce power consumption to less than a watt when there is no signal
present for extended periods.
– Variable Load Drive (VLD) providing the same power into 4Ω, 8Ω, 70V or 100V
Variable Load Drive (VLD) ensures that the powerTANK capacity is utilized efficiently,
providing consistent power to any channel with any impedance.
– amp‑LINK single cable solution for easy installation
The single cable installation feature of amp‑LINK is compatible with AES72‑1E (RJ45
connectors) wired devices. This solution provides easy installation for all four channels
without needing to wire all the connections individually.
– Advanced Protection features and PFC to ensure reliability
