PAVAVOICE NPA23 / NPA23D Network DSP Power Amplifier Malaysia

Network DSP Power Amplifier for Professional Installed Audio Systems

The PAVAVOICE NPA23 / NPA23D Network DSP Power Amplifier combines Class-D amplification, built-in DSP processing, network control and flexible Low-Z / High-Z speaker operation in a compact professional rack-mount amplifier.

It is designed for installed sound systems that require more than basic amplification — especially projects that need speaker processing, remote control, FIR filtering, system monitoring and 70V / 100V distributed audio support.

Two variants are available:

• NPA23 – Standard Network DSP Power Amplifier
• NPA23D – Network DSP Power Amplifier with Dante Audio Input

The NPA23 Series is suitable for hotels, auditoriums, performance venues, bars, stadiums, commercial PA systems and professional AV installations in Malaysia.

Powerful Class-D Amplification

The NPA23 Series provides flexible output power for professional speaker systems:

• 2 × 300W @ 8Ω
• 2 × 450W @ 4Ω
• 1 × 900W Bridged @ 8Ω

It also supports High-Z distributed speaker systems, allowing the same amplifier platform to be used in both conventional low-impedance and 70V / 100V applications.

High-Z Output Support

• 100V: up to 1 × 625W
• 70V: up to 1 × 612.5W

This makes the NPA23 Series especially useful for projects where different speaker-system architectures may be required.

Built-In DSP for Speaker Processing

The NPA23 Series includes a built-in 2 × 2 matrix DSP architecture with 24-bit / 48kHz processing.

The built-in DSP helps system integrators manage loudspeaker tuning and system protection directly from the amplifier.

DSP Functions

• 15-band Parametric EQ on inputs
• Noise Gate
• Gain Control
• 10-band Parametric EQ on outputs
• Crossover
• Delay
• FIR Filter
• Compressor
• Limiter
• Matrix Mixing
• DSP Preset Storage

Instead of using a separate external DSP for basic loudspeaker management, the NPA23 Series combines amplification and DSP processing in one device.

Low-Z & High-Z Speaker System Flexibility

The NPA23 Series supports multiple operating configurations, including:

• Stereo
• Mono
• Bridge
• Free Matrix
• 8Ω speaker systems
• 4Ω speaker systems
• 70V distributed audio
• 100V distributed audio

This flexibility makes it suitable for both direct-connected professional loudspeakers and distributed commercial speaker systems.

Network Control & Remote Monitoring

The NPA23 Series is designed for professional installations where remote control and system monitoring are important.

Supported control interfaces include:

• TCP/IP via RJ45
• USB
• RS232
• RS485

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

The amplifier also supports remote monitoring of operating information such as:

• Temperature
• Output voltage
• Output current
• Load impedance

A full-colour IPS LCD display on the front panel provides local system status and parameter information.

NPA23 vs NPA23D

Choose NPA23 if:

You need a network-controlled DSP amplifier for standard professional installed audio systems without Dante.

Choose NPA23D if:

Your project requires the same DSP and amplifier functions with Dante network audio input.
