Sherwood RX-4508
立体声100瓦接收器，支持蓝牙v3播放功能
简单而的音效和有效的解决方案，以实惠的价格迎合大多数人的愿望
简介
如果您需要或者想要环绕声，这里有很多选择，但是如果你正在寻找稳定的双声道播放，那么它们都不如RX-4508那么直接，并且它们都不会像同样的价格那样出色。
RX-4508提供2个常规模拟输入（用于CD播放机等），MM唱机输入和AM / FM天线输入，用于内置RDS调谐器。没有数字输入，我认为这是一个应该真的存在的遗漏。再一次，也许有蓝牙已经足够了。至少对于音质来说，正如我将在下面解释的那样，不需要适当的数字输入。
Sherwood仅使用dicrete电子设备建成。内部窥视表明，没有集成电路的任何地方：只使用大型线性电源变压器，较小的备用变压器，晶体管，电阻器和电容器的良好工程设计，就像我喜欢的那样。功率放大器阶段使用的似乎是三垦双极晶体管，这是一件非常好的事情。数字部分btw通过一个跨越整个单元宽度的大型散热片很好地与模拟部分分开。
蓝牙
蓝牙实施是v3，包括A2DP和AVRCP / aptX。使用蓝牙的操作不能简单：使用前面板按钮或遥控器切换到蓝牙输入，如果您尚未使用蓝牙播放设备，请选择舍伍德RX-4508和鲍勃的谚语叔叔。一旦连接，信号超稳定，在我的测试过程中不会产生一次连接。
在播放过程中，您可以通过红外遥控器，甚至通过RX4508的前面板按钮选择播放设备上的曲目。显示屏将显示“下一首曲目”，本机的行为就像是CD播放机一样。
首先，我通过蓝牙收听我的iPhone，RX4508使用其两个线路电平输出之一连接到我的主系统。Soundquality出奇的好，没有任何噪音或嘶嘶声。当然，它并不*符合Wadia 171i的要求，但当然也不会有这样的结果，因为171i提供的数字输出可以连接到DAC，而RX4508仅提供一个模拟输出。考虑到这一点，结果实际上相当令人印象深刻。
后面板采用直接导线，但也包括香蕉，只需要移除CE执行塑料盖。
之后，现在是评估放大器的时间了：集成放大器。我将它安装在我的环绕声环境中，连接到B＆W N805扬声器，通常由Yamaha DSP-Z7作为后置扬声器驱动。
RX4508使用蓝牙直接驱动N805，听起来令人放心，稳定，并且具有透明，干净的声音，功率强劲，没有侵犯。这不是一种“强壮”的声音，但也不是一种破旧的“D类”声音。清晰度和细节检索非常好，甚至比雅马哈Z7更好。水的100瓦确实能够提供，805的水平非常高。805可能不是这个星球上zui难的扬声器，但它们也不是很容易驾驶。
805 / RX4508的组合听起来非常自然和令人信服，没有明显的技巧感，因为我有类似定价的环绕音箱，如天龙的环绕音箱。当我仍然拥有Denon AVR2802时，我记得听音乐时把它连接到同一对805上，听起来很弱。然而，直接与雅马哈Z7相比，我错过了一些低音可靠性和丰富的色彩，但考虑到比较苹果和橘子的价格差异。
大部分只是为了好玩，我将Technics SL10连接到RX4508的MM输入。由此产生的声音，就像放大器的整体特征一样清晰开放。它的效果非常好，但是MM前置放大器在低音和整体色彩方面并不像我习惯于从我的主要设置中播放的特定记录那样丰满。在这方面，我更喜欢蓝牙输入。
RX4508的红外遥控器拥有人们所希望的每个按钮，甚至是直接输入选择，蓝牙音轨选择和音调控制。后者的实现我更少喜欢，中间频率似乎选择了太多的中频。添加低音时的结果太过于浑浊，添加高音时，中音会出现太多。所以zui让这些控制单独。
遥控器本身工作得非常好：即使远离放大器，朝着我的窗户（被窗帘覆盖），三室另一侧的放大器仍能反应。
