MAP I - 數位影音多聲道解碼前級

Multichannel Audio/Video Processor

Audionet 的數位多聲道解碼前級 MAP 1，輔一上市即獲德國最權威的 A/V 專刊 - "video" 極高評價。

MAP 1 採用頂級解碼晶片，能解譯所有多聲道音效格式；在功能性上，其低音喇叭管理能力(Bass Management)更是竭盡所能，滿足各式極端之使用需求與預期，除能自動分辨訊源種類外，對於 Stereo 狀態下超低音喇叭之工作與否也能靈活設定，而操作卻極為便捷。

MAP I - the big-screen A/V experience

雖然 MAP 1 配置了更多的數位輸入檔位，但也與 MAP V2 一樣，保留有 Analogue Bypass，以展現類比經驗的優異傳承；若連接外置電源供應器 EPS，則音色密度更現非凡。在影訊介面上，MAP 1 配置了 DVI 數位影像端子，能接受 HDMI 或類比色差輸入，保有最大之彈性與廣效性。

配合空間聲學分析軟體 Audionet CARMA V2 的量測與修正，MAP 1 即能啟用獨家的 MPE (Minimum Phase Equalizer) 數位等化技術，為空間聲學提供解決方案，不僅音色能平衡自然，音域音像亦更為明確。

MAP 1 率先配置電腦專用 USB 輸入端子，極具指標意義。與電腦建立連線關係，除了表示新版韌體的線上即時更新能力外，MAP 1 亦將成為電腦系統之外部解碼器 (External DAC)，成為音訊伺服中心 (Audio Server)，此時所有的 Internet 音樂資訊，都將因 MAP 1 的連結而重新定義；無怪乎德國評論員以 E=MAP1²為題，藉以影射 MAP 1 功能性與潛能之強大。

Smaller & Smarter，MAP 1 的小巧身段，說明了 Audionet 研發團隊數位系統整合能力之極致；MAP 1 的十項全能與技術落實，則宣示了 Audionet 成為嶄新世代領導者的企圖與實力。
