Symetrický zesilovač monoblock třídy D

Stealth PA-1 je symetrický koncový zesilovač monoblock třídy D. PA-1 kombinuje kompaktní rozměry, skvělý výkon a vynikající kvalitu zvuku v jednom praktickém balení.

Stealth PA-1 je ideálním řešením všude tam, kde je zapotřebí malý výkonový zesilovač monoblock. Jeden použijte pro středový reproduktor, pár pro celý systém domácího kina nebo několik monoblocků pro přidání dalších kanálů do vašeho aktuálního audio systému. Výkon 140W RMS při 8 Ohm nebo 300W RMS při 4 Ohm. Nepřehřívají se a vyžadují pouze minimální větrání. Protože je malý, PA-1 monoblock se pohodlně vejde na jakoukoliv polici a k dispozici je také sada racku pro montáž jednoho monoblocku PA-1 nebo páru vedle sebe do 1U racku. 

Nejen, že Stealth PA-1 zní skvěle, ale je také jednoduchý pro konfiguraci a používání. PA-1 běží na jakémkoli síťovém napětí mezi 100 VAC a 264 VAC, přijímá symetrický vstup pomocí XLR nebo symetrického 1/4” konektoru a může být nakonfigurován tak, aby zůstal zapnutý nepřetržitě nebo aby se automaticky zapnul, když detekuje příchozí audio signál. Komplexní ochranné obvody chrání PA-1 před různými poruchami, aniž by narušovaly kvalitu vaší hudby behěm normálního provozu, a automaticky se resetují, jakmile je chyba odstraněna.

  • Input impedance: 47k Ohms (balanced).
  • Voltage gain: 28 dB
  • Full power bandwidth: 20 Hz to 20 kHz.
  • THD+N: 0.005% at 1 kHz at 1 watt into 4 Ohms.
  • S/N ratio:

    Referenced to 1 watt (A-weighted): 91 dB.

    Referenced to full output (A-weighted): 112 dB.
  • Frequency response: 20 Hz to 20 kHz +/- 1 dB (worst case; 4 Ohm load).
  • Damping factor: >500
  • Rated load: From 2.5 Ohms to 8 Ohms.

Input And Output Connections

  • Input Connections: Balanced; (accepts XLR, balanced ¼”, unbalanced ¼”).
  • Speaker Output Connections: Audiophile grade 5-way binding posts.
  • Trigger:

    The Stealth PA-1 can be configured to turn on when an audio signal is detected.

Power Requirements

  • Anywhere between 100 VAC and 264 VAC @ 50 / 60 Hz (automatically detected).
  • Standby power: Approximately 0.275 watts.
  • Total power efficiency: Approximately 80%.

  • Auto/On Switch: 

    In the On position, AC power to the PA-1 is controlled by the AC Power switch.

    In the Auto position, the PA-1 switches on automatically when audio is detected.

Protection

  • The Stealth PA-1 is protected against excessive temperature, short circuit conditions, excessive DC offset at the output, and various input signal fault conditions. The protection circuitry in the PA-1 is totally transparent in normal operation. If a fault is detected, the PA-1 will instantly mute its output, and continue to monitor the situation. As soon as the fault is removed, the PA-1 will automatically reset itself and return to normal operation.
