SF-NP100A

RDL SF-NP100A - 100W Network Amplifier with Dante/AES67, Format-A, VCA and Compression

The RDL SF-NP100A is a professional Class D audio amplifier delivering 100 W RMS constant voltage output at 70V or 100V, designed for Dante or AES67 network audio systems. It receives four network audio channels via RJ45, converting one channel to amplified output and three channels to Format-A (Pairs A, B, C) for further distribution.

The SF-NP100A supports remote VCA level control via RDL D-RLC10KM, 10 kΩ potentiometer or 0-10 V DC. Input gain is adjusted using a rear-panel potentiometer with dual-LED VU metering. A selectable compressor adds 15 dB of headroom while maintaining audio transparency through adaptive attack and release.

Supported Dante sample rates include 44.1, 48, 88.2 and 96 kHz. LED indicators show network sync, output level, system status and Format-A voltage. The unit is UL 2043 plenum rated, includes thermal and short-circuit protection, and is housed in a rugged metal enclosure for free-standing, surface or rack mounting. External 48 V DC power supply included.

Functionality:

• output power: 100W RMS - 70V / 100V constant voltage
• network input: Dante / AES67 - 4 channels
• conversion:
  • 1 channel → amplified output
  • 3 channels → Format-A (Pairs A, B, C)
• sample rates: 44.1 / 48 / 88.2 / 96 kHz
• compressor - adds 15 dB headroom
• VCA control - remote level adjustment (potentiometer, voltage, RDL D-RLC10KM)
• LED indicators - network sync, output level, status, Format-A voltage
• power supply: external 48 V DC (included)

Features:

• all-metal enclosure - free-standing, surface or rack mount
• high-efficiency Class D operation
• protection: thermal and short-circuit
• UL 2043 compliant - plenum rated
• suitable for AV, networked audio, paging, educational and commercial systems

The RDL SF-NP100A is a powerful and flexible network amplifier for professional AV systems, integrating Dante/AES67 audio, Format-A distribution and advanced level control.
