概要

Ottocanali 4K4は、4Ω時に合計最大4000Wを出力するフレキシブルで信頼性の高い8チャンネルパワーアンプで、小規模から中規模の設置におけるマルチゾーンアプリケーションに最適です。 Ottocanali 4K4は、Lo-Zラウドスピーカー、モノブリッジ接続に対応したチャンネルペア、70V/100V Hi-Z分散型ラインのあらゆる組み合わせに対応し、出力昇圧トランスは不要です。

Ottocanali 4K4は、主/補助信号入力の切り替えが可能で、幅広いシステム制御、アラーム、GPI/O、モニタリング機能、サウンドシェーピングオプションを提供します。

PFCと特許取得済みのSRM（Smart Rails Management）技術によるユニバーサルスイッチモード電源を実装しており、信頼性と効率を最大化し、消費電力を削減します。

Powersoftが誇る効率性により貴重なエネルギーを節約し、運用コストと「カーボンフットプリント」の両方を最小限に抑えます。Ottocanali 4K4は、卓越した低消費電力と放熱性に秀でています。 これにより、AC主電源や空調・冷却システムにかかるコストが劇的に削減され、地球環境に配慮した製品となっています。

特徴

Power supply

  • Redundant universal switch mode power supply up to 400VAC tolerant with Power Factor Correction
  • Patented output filter with ripple cancellation network
  • Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
  • Detachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for USA) socket

Protections

Fully protected circuit design with:

  • Ac protection: shut down power supply when AC mains voltage is outside operating range
  • Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
  • DC protection: protects against infrasonic signal at the outputs
  • VHF protections: protects the loudspeakers against non audible, strong, non musical high frequency signals
  • Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
  • Long term limiter: protects the loudspeaker against steady long term RMS (non audio) signals, by reducing maximum output
  • Thermal protection: output stages operating temperature up to 80 °C (176 °F)
  • Temperature controlled continous variable speed fan, front to back airflow

General

  • Fixed frequency switchmode output stage for high grade sound accuracy
  • All models 2 RU for reduced rack cost and space
  • Light weight – for easier racking and shipping: 14 kg / 30.8 lbs
  • Standard Phoenix connectors: analog and digital input, audio outputs, aux supply, alarms and GPIO
  • Remotely switchable double input (main and aux) per channel

Loudspeaker system configuration

  • Direct drive either low impedance loads or 70V / 100V Hi-Z distributed lines
  • Switchable 35Hz / 70Hz high pass filter per channel
  • Mixed configuration with Lo-Z/Hi-Z systems possible
  • Bridged mode, with low impedance, per channel pair

Alarms and GPIO

  • General Purpose Input/Output alarm interfaces:
    • dangerous DC in the output power signal
    • thermal stress
  • Configurable alarm contact NC/NO per channel
  • Remote AUX input / MAIN input switch
  • Remote ON/OFF switch
  • PWS OUT connector providing up to 24VDC
