NXAMP Amplifier PS8 Series

NXAMP technology is far more complex than a bundled power amplifier and loudspeaker controller.

NXAMP Amplifier

More than two years of research yielded significant DSP innovations which allow multiple voltage/current/temperature sense lines, from the amplifier's output, to protect both the amplifier and power supply.

Processing and Control

NXAMP signal processing is identical on both models, and derived from the NX242 TDcontoller. Processing power has been increased on both CPU and DSP side. NXAMP uses twin Freescale (formerly Motorola) DSPs, with a total processing power which is 3.5 times the processing power of an NX242 fitted with an ES-4 NXtension board.

Amplifier output is now sensed in both voltage and current and 24bit converters execute these measurements. The latest generation audio converters provide enhanced dynamic range with low latency (500us) analog input to output, in FLAT mode.

NXAMP DSP Protection

  • Power-on protection (smooth start-up with in-rush limitation)
  • Power-off protection (clean shut-down procedure)
  • Peak Voltage limiter (clip limiting)
  • Peak Current limiter
  • VHF protection
  • Integrate current limiter
  • DC offset protection
  • Short circuit protection
  • Fan speed control
  • Power Amp overheat protection
  • SMPS overheat protection
  • SMPS fault protection
  • Power cable monitoring

Optional EtherSound™ Remote Control:

Rear panel expansion slot allows an ES100 EtherSound board. This offers device-to-device communication and powerful new functions including:

Ring topology:

Plugging the unused "OUT" port of the last device in a daisy chain into the unused "IN" port of the primary master creates a redundant ring topology. If the ring is open somewhere, the network automatically reconfigures itself without interrupting audio.

Third remote control port:

When both EtherSound ports are used in an EtherSound network, a third RJ-45 plug allows a computer to connected anywhere across the EtherSound network, to monitor all the devices.

Audio Inputs:

Four balanced analogue inputs on XLR3 with a second XLR3 for linking, using 24bit converters. Four digital inputs via the optional network card slot at the back.

Power Outputs:

Four Speakon outputs using internal power relay for automatic output ssignment regarding setup.

RS232 Port:

Allow firmware upgrade for software improvement and new cabinet setups.

GPIO Port:

Five Global Purpose Inputs and 8x Global Purpose Outputs for simple remote control and monitoring.
