Bose Professional PS604D 600W Adaptable Power Amplifier

The Bose Professional PowerShare PS604D is a versatile 600-watt amplifier designed for installed applications, offering exceptional audio performance and reliability. Utilizing patented PowerShare technology, it allows for asymmetrical distribution of power across all output channels, enabling each channel to deliver full power as needed. This flexibility ensures optimal power utilization without the constraints of fixed power allocations.

Supporting both low-impedance (4-8 Ω) and high-impedance (70/100V) loads without the need for bridging or jumpers, the PS604D adapts seamlessly to various system configurations. Integrated Dante® audio networking facilitates the reception of four audio input channels from a Dante network, allowing for efficient placement of the amplifier closer to loudspeakers and simplifying cable management. Configuration and control are streamlined through ControlSpace Designer software, providing comprehensive DSP capabilities and integration into larger networked audio systems.

Incorporating the Dual Feedback Loop system, inherited from Bose's PowerMatch line, the PS604D continuously monitors and controls both current and voltage delivered to each output load. This results in improved linearity, lower distortion, and enhanced loudspeaker protection. The amplifier's auto-standby feature conserves power by entering standby mode when the audio signal falls below a set threshold and waking when audio returns, contributing to energy efficiency in various applications.

Key Features:

• PowerShare Technology: Distributes the total 600 watts asymmetrically across all outputs, allowing each channel to deliver full power as needed.
• Load-Independent Outputs: Configurable for low-impedance (4-8 Ω) or high-impedance (70/100V) applications without bridging or jumpers.
• Integrated Dante® Audio Networking: Supports four audio input channels from a Dante network, facilitating flexible amplifier placement and simplified cabling.
• Dual Feedback Loop System: Continuously monitors and controls current and voltage to each output load, enhancing linearity, reducing distortion, and protecting loudspeakers.
• ControlSpace Networking: Configurable via ControlSpace Designer software for integration into larger networked audio systems with external control options.
• Integrated Loudspeaker Processing: Offers nine-band PEQs, matrix mixing, crossover, limiters, delay, mute/output polarity, and more for comprehensive DSP capabilities.
• Auto-Standby: Automatically enters standby mode when the audio signal falls below a set threshold, conserving power, and wakes when audio returns.
