PAVAVOICE NPA-46 / NPA-46D Network DSP Power Amplifier Malaysia

High-Power 4-Channel Network DSP Amplifier for Professional Installed Audio

The PAVAVOICE NPA-46 / NPA-46D Network DSP Power Amplifier is a professional 4-channel Class-D power amplifier with built-in DSP processing, network control and Low-Z / High-Z speaker system support.

Designed for larger installed sound systems that require higher amplifier output, advanced loudspeaker processing and centralised system management, the NPA-46 Series delivers:

• 4 × 600W @ 8Ω
• 4 × 900W @ 4Ω
• 2 × 1800W Bridged @ 8Ω
• Support for 70V / 100V High-Z speaker systems

Built-in DSP functions include PEQ, Noise Gate, Delay, FIR processing, Matrix Mixing, Compressor and Limiter, allowing system integrators to combine amplification and loudspeaker management within one rack-mounted platform.

Two variants are available:

• NPA-46 – Standard 4-Channel Network DSP Power Amplifier
• NPA-46D – Network DSP Power Amplifier with 4-Channel Dante Audio Input

4×4 DSP Architecture for High-Power Audio Systems

The NPA-46 Series features a professional 4 × 4 Matrix DSP architecture with 24-bit / 48kHz processing.

This allows each amplifier channel to be configured and optimised for different loudspeaker zones or system requirements.

Built-in DSP processing includes:

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

The integrated DSP architecture makes the NPA-46 suitable for projects that require high-power amplification with precise loudspeaker tuning and signal management.

Powerful 4-Channel Class-D Amplification

The NPA-46 Series is designed for applications where higher loudspeaker power is required.

Output Power

This provides significantly more output capacity for larger loudspeaker systems while retaining flexible DSP and network-control capabilities.

Low-Z & High-Z Speaker System Support

The NPA-46 Series supports hybrid power distribution for both conventional Low-Z and distributed High-Z speaker systems.

Supported configurations include:

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

This allows the amplifier to be deployed across different professional audio environments without limiting the project to one loudspeaker architecture.

Network Control & Real-Time Monitoring

The NPA-46 Series is designed for installed AV systems where remote management and system monitoring are important.

Supported control interfaces include:

• TCP/IP
• USB
• RS232
• RS485
• GPIO

Using Mconsole GUI software, system integrators can configure DSP settings and manage amplifier operation from a PC.

Real-time monitoring is also supported for:

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

A 320 × 240 full-colour IPS LCD display provides local amplifier and DSP information from the front panel.

NPA-46 vs NPA-46D

Choose NPA-46 when your project requires high-power 4-channel DSP amplification without Dante.

Choose NPA-46D when the same amplifier platform needs to integrate with a Dante network audio system.
