Pioneer PRS-D2000SPL Competition Class SPL Class-D Amplifier (4000W)

Trusted for maximum, stable and reliable power.

Designed to match our first-class SPL subwoofers, our SPL Champion Edition amps continuously break world records, pushing beyond the 180dB barrier.

They manage to do this by incorporating the very best in audio technology, to give you rock-solid, reliable power.

Main Features

• Maximum Output Power 1 x 4000W (1Ω), 1 x 3000W (2Ω), 1 x 1500W (4Ω)

• Continuous power output (RMS)
  • 1 x 2000W (50Hz/1Ω ≤ 1%THD)
  • 1 x 1500W (50Hz/2Ω ≤ 1%THD)
  • 1 x 750W (20Hz - 240Hz/4Ω ≤ 1%THD)

• Load impedance capability 1 - 8Ω

• Frequency response 10 - 240 Hz

• Distortion <>

• S/N ratio > 85 dB

• Bass Boost 40 - 120Hz
  0, 6, 9, 12 dB via remote control

• LPF 40 - 240Hz (-24dB/Oct)

• Subsonic Filter (HPF) 20Hz (-24dB/Oct)

• MOSFET output section (+) Yes

  A MOSFET output section results in enhanced high-frequency range performance and improved linear response to signals. Its high-density circuit layout reduces line impedance in the circuit pattern. This eliminates switching noise and raises sound quality and performance. In addition, amplifier drive stability is maintained even during long, hard-driving listening sessions thanks to excellent thermal stability and circuit protection.

• Sync Control Yes

• RCA terminals Yes (input/output)

• Speaker Terminals Block-type

• High Voltage Input (+) 200mV - 6.5 V

  All of our bridgeable amplifiers have an Input Level Control, which is adjustable over 6.5 volts of input signal. This means that all our amplifiers pick up signals from Hi-Volt headunits of line drivers, without any clipping.

• Input level control 400 mV - 6.5 V

• High performance balanced isolator circuit Yes

• Max. current consumption (A/4Ω) 67A

• Chassis size (W x H x D) 586 x 65 x 282 mm

• Unit weight 9.1 kg

Pioneer A-A9-J 70W Integrated Stereo Amplifier with USB Input

The sound of excellence in your living room.

The A-A9-J features AIR Studios tuning; engineers have put this amplifier through rigorous tuning, determined to deliver audio output that is as pure and precise to the original as possible.

The A-A9-J is built integrating class-AB Dual Mono symmetrical amps (which operate in pure class-A mode in low power, eliminating switching and crossover distortion).

The amplifier is also equipped with highly-efficient Twin Toroidal Transformers, which deliver stable current for powerful, clean sound reproduction.

The A-A9-J is designed to handle everything from analogue records to the latest digital audio formats; enjoy the full range of your music collection, regardless of the format.

Play your PC audio files directly through the USB input terminal, with the Sound Retriever breathing life back into compressed audio sources.

If you’re a Vinyl junky, this amplifier features the MM / MC phono-equaliser amp while an audio pre-out allows upgrading with additional power amps. The amplifier’s stable honeycomb and seamless chassis with aluminium front panel reduces resonance to an absolute minimum and eliminates ground potential differences.

Additionally, the A-A9 features a rigid under-base construction with stabilizing plate, metal insulators and aluminium side panels to even further enhance sound quality. A fully isolated quick response, non-feedback power supply unit integrates four sets of parallel ESR (equivalent serial resistance) capacitors. The result is minimal power loss with excellent response characteristics.
