Model 545AR【NEW】
2ワイヤー/4ワイヤー双方向変換インターフェイス
製品紹介
Model 545ARは、2線式(2wire)アナログパーティーライン(PL)インターコム回路と
4線式(4wire)アナログオーディオデバイスとを接続するためのインターフェースです。
(2つのアナログ入/出力チャネルを提供します。）
本機は、RTS® TW®シリーズPLインカム回路の仕様に最適化されており、マトリックスインカムシステムや他のオーディオデバイスのような4線式デバイスとの接続により、スポーツ中継やライブイベント、テーマパーク、劇場、企業のAVシステムなどのアプリケーションに最適です。なお、軽量な卓上筐体に収納された本体は、オプションの取り付けキットによりラックマウントも可能です。電源は外部DC12V供給仕様となります。(電源アダプター”PS-DC-02J”付属)
主な特長
- オートヌル機能を備えたハイブリッド回路を搭載
- 優れたオーディオ品質と高いリターンロスを実現
- 12V DCの外部電源にて駆動、インターコム回路から完全に絶縁
- パーティーラインに直接接続可能で、200オームの終端や28V DC電力を供給する機能を装備
- コンパクトな設計で、デスクトップおよびラックマウントでの使用可
