TASCAM旗舰录音笔DR

TASCAM旗舰录音笔DR

TASCAM旗舰录音笔DR-100详细剖析在介绍DR-100前,我想先谈谈TASCAM,TASCAM是TEAC在专业音频领域的牌子,涵盖了几乎音乐工业领域所有类别的音频产品,CD机、录音机、调音台、效果器、多轨数字处理器。

TASCAM发明了世界第一台4轨录音机,第一台RD AT录音机,第一台数字multitracker。

在专业录音领域,tascam积累了丰富的录音设备设计经验和数百项专利技术,和denon,marantz都是录音界响当当的品牌。

在普通家用音响市场,一些tascam的专业设备也有很多人在使用,比如经典的广播级DAT机DA60,DA60mk2,便携式DAT录音机DA-P1,便携式硬盘数字录音机HD-P2,都是在2手音响市场上常见的器材。

Tascam的器材做工扎实,牢固耐用,技术先进,在专业市场口碑很不错。

这也是我在没有任何可用信息和未曾试听的前提下毅然购入DR-100的信心来源。

前言:DR-100,TASCAM目前的旗舰录音笔,坛子里关于这个机器的帖子和谈论非常少,同火了几年的D50比起来,DR-100是一个冷门机器,受众少,谈论少,也没有一个系统的,全方位的帖子来详细剖析这个机器。

熟悉我这个ID的朋友可能知道,我D50,D1都先后入手过,也有比较详细的介绍这2个机器的帖子。

今天想和大家分享的是,我对DR-100使用和音质上的一些体会。

手里的这台DR-100是我自己数月前在ebay上购买的,邮寄花了15天,全新的机器算上运费,总成本还不到2100元,对比taobao上2499-2800多的售价,非常超值了。

因为已经使用一段时间了,机器电气特性也基本稳定,我对其也由不熟悉到逐渐了解,方方面面都有了一些自己的经验和体会。

现在开个帖子,与大家分享。

PS:考虑到DR-100的价格和D50相近,功能和定位也大致相同,我会在DR-100和D50之间做对比。

PS2:考虑到购买DR-100主要是做回放使用,本文不会对录音做太多介绍,主要内容集中在外形、做工、实用性、音质等方面。

使用的方法
什么是好的录音电平? 电平过大——过载失真。PEAK灯偶尔闪亮是正常 的,如果常亮,表示信号失真。 电平过小——信噪比下降。没有利用好数字设备 的优势,太保守。
