PAVAVOICE NPA43 / NPA43D Network DSP Power Amplifier Malaysia

4-Channel Network DSP Power Amplifier for Professional Installed Audio

The PAVAVOICE NPA43 / NPA43D Network DSP Power Amplifier is a professional 4-channel Class-D amplifier with built-in DSP processing, network control and flexible Low-Z / High-Z speaker operation.

Designed for installed sound systems that require multi-channel amplification, loudspeaker processing and remote system management, the NPA43 Series delivers:

• 4 × 300W @ 8Ω
• 4 × 450W @ 4Ω
• 2 × 900W Bridged @ 8Ω
• Support for 70V / 100V High-Z speaker systems

The series also integrates PEQ, Noise Gate, Delay, FIR processing, Matrix Mixing, Compressor and Limiter, allowing AV integrators to manage both amplification and loudspeaker processing within one platform.

Two variants are available:

• NPA43 – Standard Network DSP Power Amplifier
• NPA43D – Network DSP Power Amplifier with 4-channel Dante Audio Input

4×4 DSP Architecture for Multi-Channel Audio Systems

The NPA43 Series features a 4 × 4 matrix DSP architecture with 24-bit / 48kHz processing, providing flexible signal routing and loudspeaker management for professional installations.

Built-in DSP functions include:

• 15-band Parametric EQ on input channels
• Noise Gate
• Gain Control
• 10-band Parametric EQ on outputs
• Crossover
• Delay
• Compressor
• Limiter
• FIR processing
• Matrix Mixing
• Up to 30 DSP presets

This makes the amplifier suitable for systems where multiple loudspeaker zones or channels need to be processed independently.

Low-Z & High-Z Speaker System Support

The NPA43 Series supports both Low-Z and High-Z loudspeaker systems.

Supported configurations include:

• 8Ω
• 4Ω
• 70V
• 100V
• Stereo
• Bridge
• Mono
• Free Matrix operation

This flexibility allows one amplifier platform to serve different commercial and professional speaker-system requirements.

Network Control & Remote Monitoring

For installed AV applications, the NPA43 Series supports remote control and system monitoring through:

• TCP/IP
• USB
• RS232
• RS485
• GPIO

Using Mconsole GUI software, technicians can configure DSP parameters and manage the amplifier from a PC.

The amplifier also supports real-time monitoring of:

• Operating temperature
• Output voltage
• Output current
• Load impedance

A full-colour IPS LCD display provides convenient local status information directly from the front panel.

NPA43A vs NPA43AD

Choose NPA43 if:

You need a 4-channel network DSP power amplifier for standard professional installed audio without Dante.

Choose NPA43D if:

Your AV system requires the same amplifier and DSP functions with 4-channel Dante network audio input.
