※ 引述《ntuguy (ya)》之铭言： : : 虽然说现在的录音介面也堪用，但如果没有重大问题 : 我是很愿意购买的 : 但很奇怪的，有两点真的让我无法接受 : (1)当我把电容mic插到Saffire PRO 14号称获奖的麦克风前级 : 居然推不动，我把录音介面的gain调到80% : 录进cubase都还只有一点点讯号而已 : 如果我把gain调到90%以上，似乎又有些杂讯了 : 意味者我录音时必须费力唱很大声才能录到足够清楚的声音 : (2)他是用phone-jack接头接到监听喇叭 : 送出的讯号比我现在用RCA接头的弱了不少 : 意味着我播音乐时要把volume的旋钮开很大 : 才可以有足够大的播放效果。 : 恩，新出产的机器，不是应该录音放音更敏锐有power吗? : 为什麽这台Saffire PRO 14使用起来会有上述的严重缺点呢? 第二点我没试过，但他的耳扩是不太够力的如果你要推高阻抗耳机(数百欧姆) 而且IMO，低频有点太多 不过我的pro 24好像有同轴输出，应该可以用这接speaker 同轴跟一般的phone jack的测试之後我有钱买监听喇叭时会再测试看看 第一点的mic pre，我爬一些国外的review後发现 他的mic pre只有大概+55db左右 不过这样的设计还是有处理方法 摘录其中一段我觉得写的很有道理的 The thing is with digital recording, the level recorded to track doesn't really matter. In digital, boosting the level in the box, only boosts the level of what's been recorded, there's no tape hiss it's boosting as well, which was why it was so important to get a hot signal on tape. So the solution for me? Boost the gain to get the source signal as high as you can before you the self noise of the pres becomes significant. If you have to boost the headphone level, or boost the level via DAW, do it. Personally, I would prefer to be able to record a -3db signal, but if it means recording a noticeable level of noise. There's no technical reason why it would be bad to record with your signal peaking at -15 or -10, because you can just boost it in the DAW with no added noise. If you can keep your gain setting below 7 or so, the noise floor is much lower than anything else I have ever used in the same price range, and the quality of the audio is much more pleasing as well. 当然如果mic pre可以gain一点的话是更好啦... 不过这样的设计应该也还在OK的范围就是 另外这是Focusrite官网回应： The Saffire microphone preamps provide between +10dB and +55dB of gain to the input signal before the converters. The gain required to obtain an acceptable signal level will depend on several factors including the input source and the type of microphone. For example, signals with a high SPL like those from acoustic drums and guitar amplifiers aren't likely to require much amplification so it's normal to set the gain on the lower range. This is particularly true if a sensitive condenser microphone is utilised. Quiet signals such as vocals will requires more amplification, particularly if used with a dynamic microphone. The gain change by the potentiometer isn't linear and it's not unusual to require setting the gain towards the high extreme to get a reasonable signal level. The Saffire preamps are designed to sound good at both extremes of the gain scale as well as everywhere in between so setting the gain on its highest setting is not anything to be concerned about. -- "Dave wants girl, Dave can't have girl, Dave kills people!"
