Em chỉ dùng mấy tính năng sau : , expander, compressor, normalizer
để mấy bữa e post thông số chi tiết nhé

My father bought a Sennheiser e945, it's a dynamic mic. I don't know if it's any good since I don't sing Karaoke.
But what surprised me was that it didn't have an on/off switch. I've read here that it's better to switch the mic off when not singing.
So should I tell him to get 1 with a switch? Or does it have little impact? Anyone tried that mic and is it any good?

Second, I've read here that XLR cables are better, but my father's mixer doesn't accept that connection. Right now he has XLR to TS.
So the better choice would be to have an XLR to TRS (balanced) cable right? Would it better to buy a XLR to XLR cable and add a TRS adapter?
Or is just the same thing. I'm a little confused.

Thanks a bunch.

Chào Baldinghamster,
Senheiser only make cable mic e815s that has on/off switch. This mic is discontinue, u may find it on ebay.
Senheiser e835 or e945 cable mic doesn't has on/off switch.
My brother in-law own the e945 and he liked it.
Senheiser make good cable mics, I own some e815s and e835 cable mic. And wireless mic.
The 1/4" mic input at the mixer is mono so buying xlr cable with trs adapter will not solve the problem.
If the mixer mic channel has on/off switch for that channel then use that to turn off when mic is not in use otherwise turn the mic volume down.

Is the mic(e945) causing a problem or the feedback causing a problem?

Explain the system sound: bị rè, bị hú,humming noise or something else.

I know this is a late response. I just want to add my thought in case anyone else has the same issue.

Baldinghamster, the noise you hear is called "self-noise" that each equipment has and contributes to the final sound. Most likely, it is coming from the mic Pre-amplifier inside your mixer. The home-style "karaoke mixers" are notorious for having noisy pre-amps. The fact that they only accept TS connectors for microphones make it even more susceptible to interference noise that is picked up by long, unbalanced mic cables. We think that if we connect a cable with TRS connectors into a karaoke mixer that accepts TS connectors will decrease the noise, but it does not help. (It's like watching VHS tapes with an HDTV will not turn the video quality into high-definition.)

What can you do to get rid of the noise completely with this kind of home-style karaoke mixer? Nothing. You need to buy a mixer with quieter mic pre-amplifier.


By the way, I will use your problem and add it to my FAQs in the original post. Thanks for bringing up the issue.

I'm glad to hear that it's been helpful. There have been many posts and recommendations on different components. You can search the forum for other people's inputs and reviews. There are just TOO MANY WAYS to build a karaoke system. Most importantly, your karaoke system ultimately depends on YOUR BUDGET and HOW USER-FRIENDLY you want it to be.


As a starting point for a budget of $1,500 USD, easy to set up and control, AND still sounds great, I suggest the following:

1. Mics: two MXL V67g (or any large condensor mics for under $100 each). $200
2. Mixer: Allen & Heath ZED 10FX. Price: $240
3. Speakers/Amps: a pair of EV ZXa1 powered speakers ~ $1,000
4. (And four 25ft XLR cables for the two mics and two speakers) ~ $45 for all four at MonoPrice.

DONE.

Those are retail prices. I always start off by looking at MusiciansFriend.com for standard price. Then, I look on Amazon/Craigslist/eBay to see if I can find more savings.

Some people may question my pick on using studio recording mics like MXL V67g for live use (instead of Shure SM58 or Sennheiser series). I'd say that large condensors will give you a lot more sound quality for the same price. Yes, they are sensitive to moisture (spit), but I'd sacrifice durability for the "Oh, so good!" sound.

If your budget is bigger, get A&H ZED 12FX so it has inserts for compressors. Buy an external compressor (to control the dynamics of your voice) like a DBX 266XL or FMR RNC for ~ $100.

For a lot more money and slightly better sound, you can buy QSC K8 speakers instead of those EV ZXa1. (I prefer the powered speakers because I don't have to worry about which amplifier to buy and how to match the Ohm and Watts appropriately with the speakers.)

If you already have a receiver and home theater speakers, then you don't have to buy new speakers. I think they are good enough for karaoke (as long as they are not small cube-like speakers). Plus, they look so much better than those bulky PA speakers.



Once again, a karaoke system can be as complex as you want it to be. For me, sound quality has to be the #1 priority. Then I pick my components based on this question:

-Do I want other people in my family to know...how to turn it on?...and adjust the settings by themselves? (Yes, I do. So I can't add too many components. Too many knobs will scare them.)


Other than that, I can't tell you how those individual components will sound ...ALL TOGETHER in YOUR ROOM with YOUR VOICE. You just have to buy and experiment.
