比人耳听觉系统更灵敏

独一无二的底噪抑制设计

若想从纯技术的层面了解人耳的听力水平,不妨参考人耳听力阈值曲线,请注意,这一阈值很大程度上受到频率的影响,在 2 – 5 kHz时人耳最敏感,频率过低和太高,敏感度则会下降。将人耳听力阈值和LCT 540 SUBZERO的底噪值做对比,您能清楚地看到我们麦克风一直低于人耳听力阈值,这意味着我们的麦克风能拾取比人耳更细微的声音。当然,作为一支高端麦克风,底噪曲线并不足以说明它的所有特性。

向极限逼近

4.5吨测量试验

麦克风越好,底噪就越难测量。想要得到准确的测量数据,我们必须在一个没有外界噪音干扰的地方进行实验,这对于测量低频尤为困难,为了测量LCT 540 SUBZERO的底噪,我们做了一个总重量超过4.5吨的测量盒,重量大致相当于普通测量盒的十倍,它有效地抑制了低频杂音,使其在麦克风的20到20kHz全频段范围内被降低了60dB,部分高频部分降低了80dB以下。

重中之重

为何低底噪如此重要?

在晴朗的好天气去爬山,你将收获绝美的风景。但如果有雾或乌云,体验感肯定会大打折扣。录音时也有类似的情况,峰值产生时麦克风会有较强的底噪,这会破坏音质。但如果尽可能地去除这些噪声,那之前被遮盖的声音便会清晰无暇。在人声和乐器的拾音上,这款麦克风表现十分敏锐。细微到听不清的耳语也能被捕捉并呈现出如水晶般清澈的音质。许多噪声问题只会在后期制作中暴露出来,信号经过压缩器之后,之前未被察觉的底噪就会出现。但拥有LCT 540 SUBZERO,这个困扰将烟消云散!

Reviews

“Overall its technical ability is sublime; it sounds warm, clear (not yet clinical), smooth and dynamic. I would look forward to further using a pair for a live classical recording - lessening the need for noise reduction tools in the mix stage. Thank you to LEWITT for pushing innovations and setting new benchmarks for microphone manufacturing.”

Ross Simpson, Audio Media International

Reviews

“This cardioid condenser shows its quality right away, sitting effortlessly next to a mic more than twice its price across a range of sources. For vocal work it ticks all the boxes, possessing great clarity along with an easily worked proximity buildup, a smooth high end and all the low-end richness you need for voiceovers or in-your-face breathy vocals. The condenser mic HF lift is subtle and free from phasey peaks, keeping sibilance natural and easily controlled.”​​​​​​​

Reviews

“It’s not too crisp, has zero muddiness, and is best described as detailed, full, and musically honest. [...] Also, due to its clean nature, the LCT 540 SUBZERO makes not only an incredibly detailed vocal mic, but also a great closeup/intimate mic on the quietest of sources.”

Paul Vnuk Jr., Recording Magazine

Reviews

“Given that it is a mid-priced mic with a somewhat lower price tag than I expected from its performance, the LCT 540 SUBZERO represents extremely good value and is capable of taking on a wide range of recording tasks.”​​​​​​​

Paul White, Sound on Sound

Produce Like a Pro

“What better way to test out a new mic than to record a full song using ONLY THIS ONE MIC! The song we recorded only using the Lewitt LCT 540 Subzero is called “Nothing I Can Say.” I wrote this song with Buck Johnson, Aerosmith’s keyboard player (before he was Aerosmith’s keyboard player!) In this version of the song we have Matt Starr (Mr. Big, Ace Frehley) on drums and myself playing the rest of the tracks!”
