From the project
エフェクター展示会の試奏ブースでのコミュニケーションを円滑にするために設計されたヘッドフォンアンプです。ギター/ベースの音と会話用のマイク音声をミックスし、ヘッドフォンで聴くことができます。試奏者と出展者が音を共有できると共に、ヘッドフォンを外さずに会話することが可能となります。

※ 電源は、DC9V(センターマイナス)出力のACアダプターで、0.3A以上の電流出力が可能なものを使用してください。
それぞれ独立したゲイン調整を備えています。ゲインを上げ過ぎるとハウリングが起こることがありますのでご注意ください。
楽器側の音声出力を接続します。アンプ・キャビネットシミュレータからの接続を想定しています。ゲインは基本的に中央で固定し、微調整として使用してください。
外部マイクを接続します。48Vファンタム電源が必要なマイクには対応していません。
