小长假入了v200,有些问题不太清楚直接邮件问的德国公司了
之前一直在犹豫配什么耳放搭配我的hd650，考虑过莱曼、solo钻石、ha-3等等，最后还是咬了牙小长假期间买了v200，在使用中有些情况不太明白，就直接按照说民书上的邮件地址发了邮件直接咨询Lake People公司了，没想到两天后对方回消息了，以下是邮件内容，希望可一个大家借鉴。我说：

Dear Lake-people：
I am David.Li from Shanghai China，
I bought violectric HPA v200 Headphone Amplifier yesterday in Shanghai.
When I use this Ampilfier with my HD650 eraphone, I discovered that when I open and close the v200 power button, the amplifie will always send a "chip" noise sound, I will heard in the earphone, the voice is very clear and harsh .I want toknow if this is normal phenomenon?Can I eliminate the noise?
And I also want to know whether this voice will have bad effects on the headphones?
I am looking forward to receiving your professional reply.
Thanks!
Yours respectfully!
Best regards !
David.Li
德国公司老板回答：
Hello David, V100, V181 and V200 comprise a relay in the audio path which is to protect your headphone from chip noise and other unwanted effects during powering on/off.The relay drive also includes a delayed switching-on and rapid switching off after power on/off.
So please examine if there is a signal present directly after power-on or if there is a short delay of about 3 seconds.
Also a little click has to be heard from the inside after some seconds, indicating that the relay is activated.
If not, the relay drive is somehow faulty and needs repair.
Please come back to me as soon as possible.
Best Regards
Fried Reim

我回复：
According to your requirement, I made the following experiment many times:
2.5 seconds later after I (open) the v200 power button,I do hear a sound like "click" though my headphone, Also a little click has to be heard from the v200 at the same time.
The important thing is: When I close the V200 power button,I will heard a more loud and harsh suond.
Does this is a normalnormal phenomenon?

我在等对方的答复，呵呵
建议应该用switch on off ，而不是open , close，呵呵容易让人误会 嗯嗯，英语很久不用了，很蹩脚的英语，还好对方能看懂:$ 你是关机的时候有电流冲击声音吗？
Lake people老板人很好的，我和他聊了很多技术问题。
不过有一次，我说V800的瞬态不及MEDEA+，他有点急了，估计觉得我要求有点过，说不指望V800能和MEDEA+这个级别的机器比。 V200用家表示如何开关机，如何拔插耳机都没杂音。。;P ;P 原帖由 maxwelx64 于 2013-4-9 00:15 发表 http://bbs.headphoneclub.com/images/common/back.gif
V200用家表示如何开关机，如何拔插耳机都没杂音。。;P ;P
不是指耳机里的杂音 是指的开机的时候会听到“磕啪”一声 不带耳机也能听到 是的， 我就是开关机，特别是关机有明显的“啪”的声音，我把耳放音量关到最小，而且电脑音源也关掉一会了，等于是前段什么都没有，也是有这种声音。担心会不会损伤耳机。 许多人喜欢开机插耳机，关前拔耳机。觉得多此一举了
除非耳房设计有问题，开关的冲击声不会对耳机造成问题，哪怕是低阻
grado的ra1的开关冲击听过吗？够响吧？
grado怎么回复的？回答说：其实开关冲击声音可以去除，但是复杂化了，因为无害，所以不必。
解决方法：开机再戴上耳机;P
[ 本帖最后由 headfan 于 2013-4-9 09:35 编辑 ] 哦哦，谢谢了 v200的这个声音跟插不插耳机没关系的 不插耳机 开机的时候也能清晰的听到“啪”的一声 你说对，按照厂家说，开机时会有一个延时继电器打开，那个声音是继电器发出的，而关机的声音是内部残留的电压造成的。
老板回复：
Hello David,
so it seems that your V200 is operating normal.
The more loud and harsh sound (for a very short while) when switching off your V200 is due to the "dying" operation voltages inside.
Best Regards
Fried 继电器一般是嗒的一声，不会太响的。
嗒的同时耳机可以听到开始出现声音了，这都是正常的 嗯嗯，谢谢了！另外还有一个问题不知道大家知道吗？就是v200后面的RCA输入端同事标有in/out,也就是既可以RCA输入也可RCA输出，我看默认是输入的，那要他RCA输出怎么调整呢？ 只要不用搬动就不拔耳机的路过。有问题直接问厂家是好做法。 原帖由 lxjbm 于 2013-4-9 10:15 发表 http://bbs.headphoneclub.com/images/common/back.gif
