Bosch PRM-4P600-EU audio amplifier 4.0 channels Black

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

powerTANK
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.

Variable Load Drive
Variable Load Drive (VLD) ensures that the powerTANK capacity is utilized efficiently, providing consistent power to any channel with any impedance.

dualCOOL
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
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.

amp‑LINK
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.

PFC power supply
Equipped with a PFC power supply and protection features usually reserved for the professional power amplifiers, means that the amplifier resists complete shutdown situations and will always perform at its best under all conditions.

Architects’ and engineers’ specifications
The 4‑channel amplifier shall have a total power of 600 W, be able to adapt the power of the output channels with power sharing in either 4 ohm, 8 ohm, 70 V or 100 V conditions on any channel simultaneously. The amplifier housing shall be a 1” rack unit size design. The amplifier shall have a thermal design that can operate as passive cooled device, but also be able to activate forced air-cooling Communications Systems - PRM-4P600-EU Power amplifier, 600W, 4 channel, EU 2 | 4 when required under extreme conditions, to avoid reduction in available power. The reliable thermal operating range of the device shall be < 45 °C without reduction or shutdown. The amplifier shall have an automatic power down mode that can be turned on or off with a standby consumption of < 1 W. The amplifier shall also have a low power consumption feature whereby significant power consumption is reduced maintaining the output modulation suitable for background music. The amplifier shall be able to connect audio as either input or through to other devices using the AES72‑1E wiring protocol. The amplifier shall be equipped with a PFC power supply and protections to ensure reliable and safe operation including High Frequency Limiter (HFL), Output Current Limiter (OCL), Rail Supervision Limiter (RSL), High Frequency Protection (HFP), DC Protection (DCP), Over Current Protection (OCP), Mains Fail Protection (MFP), Output Balance Protection (OBP), Over Temperature Protection (OTP), Over Voltage Protection (OVP). The amplifier shall be the Bosch PRM-4P600 power amplifier.
