RAM Audio PowerPack DSP SB 6K Tri Plate Amplifier

The RAM Audio PowerPack SB 6K Tri is a high-power 3-channel Class-D plate amplifier module designed for multi-way self-powered systems, asymmetric loads, and sub-sat configurations. Positioned within the SUB series, it combines a regulated universal switching power supply with advanced FIR-capable digital signal processing, delivering versatile power distribution across three independent channels within a unified chassis layout.

Key Features

• Integrated Digital Signal Processor: 64-bit double-precision 96 kHz DSP utilizing 96 kHz/32-bit AD/DA converters. Features up to 2000 taps custom FIR filters, 10 IIR EQ filters per input, 12 IIR EQ filters per output, and a minimal latency of 0.6 ms.

• Acoustic Time-Alignment: Offers extensive delay options with up to 40 meters (116 ms) available per channel to ensure precise driver integration across sub and satellite channels.

• Preset Management: 4 quick-presets selectable via an external hardware button, backed by an internal memory library capable of storing up to 20 user presets.

• Networking and Control: Dual-port RJ45 Ethernet switch supporting daisy-chain configurations for telemetry monitoring and DSP adjustment. Dedicated USB Type-B port for configuration adjustments and firmware utility installations via RAM_OCS control software.

• Monitoring Interfaces: Physical hardware indicators for standby mode, signal presence, operational status, input/output levels, temperature tracking, current draw, and real-time impedance monitoring.

• Power & Safety Architectures: Incorporates Advanced Power Management System (PMS™), Intelligent Clip Limiting (ICL™), alongside defenses against turn-on transients, overheating, DC faults, RF signals, short circuits, and mismatched loads.

• Physical Connections: Neutrik-sourced hardware including an XLR input, XLR link out, powerCON True1 input and output loop, and internal double screw-terminals for speaker routing.
