テストコンフィギュレーション

2Wスピーカー3台接続時のテスト結果
|
70V/100Vディストリビューション・スピーカーシステムのテスト
MR-PROは、接続されたディストリビューション・スピーカーシステムの皮相電力と位相を測定します。スピーカーシステムが正しく接続されている場合、テスト結果から、パワーアンプに必要なパワーレシオに加え詳細な情報が得られます。全ての測定において、100Vパワーアンプはディストリビューション・スピーカーシステムから外しておく必要があります。標準のテスト周波数は1kHzです。
Minirator MR-PROは、次のような問題の発見に役立ちます。
- スピーカーが接続されていない
- スピーカーの接続ミス
- 誤ったトランスフォーマータップへの接続。例えば、正しくは2Wのところへ1W
- 回路のショート
- 火災報知機など、他の機器を誤って接続
- ケーブルの接続不良
MR-PRO測定技術の優位性:
一般にスピーカー付近の振動や環境騒音は、他のテスト機器ではスピーカーインピーダンスに影響を与えます。MR-PROのインピーダンス測定テクノロジーは、騒音のある環境においても安定した読み取りが可能です。
