Presentation Transcript

  1. YDA138(D-3) 特 性 • 輸出功率大: 10W*2ch @12V RL=8ohm (RL=4ohm ) • 高音頻特性: THD+N=0.02% , S/N=100dB • 電源選擇範圍大: 9V – 13.5V • 10W*4通道同步操作 • 內置4步音量控制功能 • 輸入/輸出 模擬輸入 / 脈寬調制輸出 各種特性 抑制Pop噪音,過熱 &過電流保護 以42HSOP封裝,內置散熱墊 內置AB類耳机功放 內置過電流檢測電路

  2. D-3/D-3D/D-3M 概 要

  3. YDA138規格對照表 雅瑪哈的優勢: 非常少的外圍電路 ---免濾波器 --- 無需散熱片 高質量音頻輸出 多通道同步

  4. 為什麼說雅瑪哈的更好? “脈沖直接驅動揚聲器”電路能夠抑制由揚聲器背面的電動勢 或電源的波動引起的音頻質量衰減. > 失真和輸出噪聲不到其它競爭者的一半

  5. 系統配置 & 內部模塊

  6. YDA138 應用實例 立體聲模式 單聲道模式
