Sherwood RX-4508
立體聲100瓦接收器，支持藍牙v3播放功能
簡單而的音效和有效的解決方案，以實惠的價格迎合大多數人的愿望
簡介
如果您需要或者想要環繞聲，這里有很多選擇，但是如果你正在尋找穩定的雙聲道播放，那么它們都不如RX-4508那么直接，并且它們都不會像同樣的價格那樣出色。
RX-4508提供2個常規模擬輸入（用于CD播放機等），MM唱機輸入和AM / FM天線輸入，用于內置RDS調諧器。沒有數字輸入，我認為這是一個應該真的存在的遺漏。再一次，也許有藍牙已經足夠了。至少對于音質來說，正如我將在下面解釋的那樣，不需要適當的數字輸入。
Sherwood僅使用dicrete電子設備建成。內部窺視表明，沒有集成電路的任何地方：只使用大型線性電源變壓器，較小的備用變壓器，晶體管，電阻器和電容器的良好工程設計，就像我喜歡的那樣。功率放大器階段使用的似乎是三墾雙極晶體管，這是一件非常好的事情。數字部分btw通過一個跨越整個單元寬度的大型散熱片很好地與模擬部分分開。
藍牙
藍牙實施是v3，包括A2DP和AVRCP / aptX。使用藍牙的操作不能簡單：使用前面板按鈕或遙控器切換到藍牙輸入，如果您尚未使用藍牙播放設備，請選擇舍伍德RX-4508和鮑勃的諺語叔叔。一旦連接，信號超穩定，在我的測試過程中不會產生一次連接。
在播放過程中，您可以通過紅外遙控器，甚至通過RX4508的前面板按鈕選擇播放設備上的曲目。顯示屏將顯示“下一首曲目”，本機的行為就像是CD播放機一樣。
首先，我通過藍牙收聽我的iPhone，RX4508使用其兩個線路電平輸出之一連接到我的主系統。Soundquality出奇的好，沒有任何噪音或嘶嘶聲。當然，它并不*符合Wadia 171i的要求，但當然也不會有這樣的結果，因為171i提供的數字輸出可以連接到DAC，而RX4508僅提供一個模擬輸出。考慮到這一點，結果實際上相當令人印象深刻。
后面板采用直接導線，但也包括香蕉，只需要移除CE執行塑料蓋。
之后，現在是評估放大器的時間了：集成放大器。我將它安裝在我的環繞聲環境中，連接到B＆W N805揚聲器，通常由Yamaha DSP-Z7作為后置揚聲器驅動。
RX4508使用藍牙直接驅動N805，聽起來令人放心，穩定，并且具有透明，干凈的聲音，功率強勁，沒有侵犯。這不是一種“強壯”的聲音，但也不是一種破舊的“D類”聲音。清晰度和細節檢索非常好，甚至比雅馬哈Z7更好。水的100瓦確實能夠提供，805的水平非常高。805可能不是這個星球上zui難的揚聲器，但它們也不是很容易駕駛。
805 / RX4508的組合聽起來非常自然和令人信服，沒有明顯的技巧感，因為我有類似定價的環繞音箱，如天龍的環繞音箱。當我仍然擁有Denon AVR2802時，我記得聽音樂時把它連接到同一對805上，聽起來很弱。然而，直接與雅馬哈Z7相比，我錯過了一些低音可靠性和豐富的色彩，但考慮到比較蘋果和橘子的價格差異。
大部分只是為了好玩，我將Technics SL10連接到RX4508的MM輸入。由此產生的聲音，就像放大器的整體特征一樣清晰開放。它的效果非常好，但是MM前置放大器在低音和整體色彩方面并不像我習慣于從我的主要設置中播放的特定記錄那樣豐滿。在這方面，我更喜歡藍牙輸入。
RX4508的紅外遙控器擁有人們所希望的每個按鈕，甚至是直接輸入選擇，藍牙音軌選擇和音調控制。后者的實現我更少喜歡，中間頻率似乎選擇了太多的中頻。添加低音時的結果太過于渾濁，添加高音時，中音會出現太多。所以zui讓這些控制單獨。
遙控器本身工作得非常好：即使遠離放大器，朝著我的窗戶（被窗簾覆蓋），三室另一側的放大器仍能反應。
