擴大機 | 520 W 總功率 | 4 x 130 W @ 2ohm | D 級
Audison SR 4.300 四聲道擴大機，具有交叉過濾器和超緊湊設計，提供強大功率（4Ω 下每聲道 85W）。SR 系列採用了最新的 ADT（Audison D-Class Technology）技術，顯著減小尺寸的同時保留了卓越的音效表現。經過無數專業和發燒友的聆聽測試，Audison 的研發團隊決定為此系列擴大機引入此新技術。外觀和功能的每一細節都經過精心設計，擴大機外殼使用擠壓鋁材，邊角圓潤，方便在狹窄空間中安裝。兩側的散熱片設計不需要內部風扇，減少了噪音和灰塵積累。SR 系列延續了其多功能性，所有型號均配備完整的過濾器部分，適用於任何音響系統配置。控制面板設計精美，保護在鋁合金表面，方便安裝後操作。當系統包含 Audison bit 處理器時，可以完全排除過濾器部分。
透過 Audison USS（Universal Speakers Simulator）技術，SR 擴大機可方便地與配備 "揚聲器負載檢測" 功能的 OEM 音源連接，實現音頻輸出。SR 4.300 支援多種連接方式，所有型號配備平衡高電平輸入，可連接 OEM 主機揚聲器輸出，還有低電平 RCA 端口可連接後市場揚聲器。當使用高電平輸入時，還可啟用 ART（自動開關）功能，通過主機開關來控制擴大機開啟。此外，還有遠程 IN / OUT 插孔可用來控制多個擴大機聯動開關，實現所需的開啟狀態。
Amplifier | 520 W total power | 4 x 130 W @ 2ohm | D-class
Audison SR 4.300 4-channel amplifier with crossover and great power packed into ultra-compact dimensions (85 W x 4 4Ω)SR line, perfected by taking full advantage of the capabilities of the latest amplification devices. After numerous listening tests with professionals and enthusiasts, Audison's R&D team decided to adopt a new class D technology called ADT (Audison D-Class Technology) for this line of amplifiers, which has made it possible to considerably reduce their size, totally preserving the audio performance that characterises every Audison design.As far as the electronic design is concerned, every aesthetic and functional detail of the Audison SR 4.300 has been taken care of, resulting in a compact amplifier made of extruded aluminium with rounded corners, which facilitates the installation of the product in narrow spaces. Thanks to the generous heat sinks on the two short sides of the amplifiers, there is no need for internal cooling fans, which often cause noise and dust accumulation.In keeping with tradition, the SR amplifiers confirm their vocation for versatility by including on all models a complete filter section, suitable for any kind of audio system configuration. The controls, protected by a satin-finished aluminium panel, are located on the top panel of the amplifier, so that they can be easily reached from above, even after the product has been installed. When the system includes an Audison bit processor, the filter section can be totally excluded.Audison USSThanks to the integration of Audison USS (Universal Speakers Simulator) technology in the high level inputs, the SR amplifiers can also be conveniently connected to OEM sources equipped with the 'speaker load detection' function, which monitors the presence of a low impedance load enabling the audio outputs.Audison SR 4.300 allows multiple connectivityAll models have balanced high-level inputs for connecting to the OEM headunit speaker output and a low-level RCA for after-market speakers. When using the high-level input, the ART (Automatic Remote On/Off) function can be enabled to control the amplifiers' power-up with the headunit's power button. In addition, there is a remote IN / OUT socket to allow control of multiple amplifiers in cascade that turn on when needed.Through the PRE-OUT signal using the Speaker-IN socket it is possible to interface the amplifier with OEM sources that only have amplified outputs, allowing for system expansion.
