Product Overview
The AM650 Plate Amplifier is a powerful and energy-efficient Class D DSP plate amp module designed for active speaker systems. It delivers 650 W into 8 Ω (700 W into 4 Ω) under full DSP control. Featuring an integrated switching power supply, embedded DSP for EQ, crossover, delay and limiter processing, and dual RS-485 ports for remote control, the AM650 provides high fidelity, low distortion, and robust protection. Its slim, lightweight design ensures easy integration into speaker cabinets and installation scenarios.
Key Features & Advantages
1. High Power & Efficiency
The AM650 produces 650 W into 8 Ω and 700 W into 4 Ω, thanks to its advanced Class D architecture. This high power output with low heat and excellent efficiency renders it ideal as a plate amplifier module in demanding audio systems.
2. Full DSP Processing & Remote Control
It integrates a DSP engine enabling crossover, parametric EQ, delay, limiter, and protection. Twin RS-485 ports support multiple configuration and monitoring, making it a smart DSP speaker amplifier for networked setups.
3. Audio Quality & Protection
The amplifier maintains THD+N < 0.1 % at 1 kHz (1 W into 8 Ω) and SNR > 100 dB. It supports protections including short circuit, over-temperature, over-voltage, under-voltage, over-current, and DC protection. This ensures stability and trustworthiness in high power plate amp use cases.
4. Global Voltage Support & Compact Design
The AM650 supports two voltage ranges (90–135 V and 180–265 V), suitable for various regions. Its slim footprint (332×142×70 mm) and light weight (1.7 kg) enable seamless integration into tight speaker enclosures or wall mounts without adding bulk.
5. Scalable Architecture & Flexibility
While AM650 is a single-channel version, it shares architecture with multi-channel DSP amp modules, enabling scalable product lines across stereo or multiway speakers, all using the same DSP and plate amplifier platform.
Application Scenarios
• Powered Loudspeaker Systems
Embed the AM650 plate amplifier module in full-range or subwoofer speaker enclosures. Its compact form and high output power turn passive boxes into high-performance active speakers.
• Portable PA & Rental Gear
Its lightweight, efficient design is ideal for building road-ready powered speakers for events, DJs, stage monitors, or portable PA systems where reliability and portability matter.
• Permanent Installations
Use AM650 in installed audio systems in houses of worship, auditoriums, clubs or conference rooms. Hidden within cabinetry or behind panels, yet remotely adjustable via RS-485 control.
• Custom & OEM Speaker Projects
For speaker OEMs or DIY enthusiasts, AM650 offers a turnkey amplifier + DSP core. It accelerates development, ensures consistency, and gives professional performance with minimal additional design.
