Members stompinne Posted February 19, 2007 Members Share Posted February 19, 2007 I can buy this mic-set for approx. 100 euro's: http://www.dbtechnologies.com/mod_produkte.cfm?pid=8&pgid=10&pugid=26&psugid=32 Which seems to be cheaper than other brands/products...Anyone knows its limitations, quality?With how much distance does this work?

Members prosigna Posted February 19, 2007 Members Share Posted February 19, 2007 I cannot comment on that product. I will say this: Wireless and Cheap are mutually exclusive words. Link to comment Share on other sites More sharing options...
Members GigMan Posted February 19, 2007 Members Share Posted February 19, 2007 I cannot comment on that product. I will say this: Wireless and Cheap are mutually exclusive words. Right - they are words that should not be used in the same sentence by a professional/semi-pro musician. Spend the money, get something decent - move on. The Audio-Technica 3000 series is often recommended here: http://www.audioeast.com/atwireless.htm ...not the very top o' the line but one notch below it, I think.

Members agedhorse Posted February 19, 2007 Members Share Posted February 19, 2007 Wireless and cheap usually = unsatisfactory unless you have very low standards for your equipment's performance and reliability. Link to comment Share on other sites More sharing options...
Members boseengineer Posted February 19, 2007 Members Share Posted February 19, 2007 I'd be careful with E-bay. If it's too good to be true, than it's usually not true. In regular intervals there is a Bose wireless microphone popping up there at a really good price. The problem is, we don't make a wireless microphone. We shut down stores with products that has "fallen off the truck" on a regular basis. There are also a fair amount of far-east fakes out there. I have to admit the guy with the microphone has some guts: slapping our name on a product that doesn't even resemble anyting we make is fairly bold.

Members daklander Posted February 19, 2007 Members Share Posted February 19, 2007 The company actually produces a digital wireless mic that looks intriguing. DWS2400 M Vocal-SetDigital Receiver 2400R * 16-channel Dual-Band receiver * intelligent frequency-scan software * UHF True-Diversity * Digital Code Squelch * 2,4Ghz Patch-Antenna * LCD display for frequency signal strength and audio status * Battery status LED (from transmitter) * Balanced XLR & unbal. Jack output * output level adjustable * connectors for external Antennas or Splitter * Robust metal 9,5" housingDynamics unlimitedAnalog Wireless Systems always require a compander system to reduce the signal to noise ratio to an useable level, meaning the signal is being compressed in the transmitter and on the other side decompressed in the receiver.This method is required in every analog wireless System. Unfortunately this limits the range of dynamic, in particular for guitarists and bass players. With the digital wireless transmission the analog technology will become redundant. The signal gets converted through a high profile Delta Sigma 20bit AD-Converter in the transmitter into digital data.Those data packages are sent to the receiver to be converted back into an analog signal. This technology alows a natural, full dynamic range. The data transmission avoids also the frequency modulation of an analog system. The result is a christal clear sound without hissing.Transmission from 20-22KHzThe frequency range of a DWS2400 System means CD-Quality. The sampling rate of 44.1KHz gives an unbelivable range of 20Hz to 22KHz! Analog systems only manage a range of 50Hz up to 15KHz due to the method of construction.GigahertzThe DWS 2400 works on a 2.4GHz basis, basically the upper UHF range, allowing an enormous amount of broadband data transmission. This method requires a special antenna technique, which we implemented in the 2400 R receiver, the so called PATCH - Antenna. This is mounted on top of the receiver and can be flipped up easily.The DWS2400 System works on the principle of true diversity technology, meaning two separate receiver channels work independently controlled by intelligent electronics to always process the best incoming signal makeing the system as reliable as possible.The known latency ( delay ) of digital signal processing is an outstanding 2 ms and therefore not noticable for the user.DWS 2400 M/MCFor Vocal Artists with high expectations to sound performance. The ergonomic shaped handheld microphone, made out of rugid metal and integrated display is available either with a dynamic hypercardoid beyerdynamic TG-X 58 capsule or with a high quality beyerdynamic condenser capsule. Some of their other gear looks decent too, with a initial quick glimpse.Will have to do some additional research on the company and product line.

Members agedhorse Posted February 19, 2007 Members Share Posted February 19, 2007 If it comes from overseas, it most likely will not be suitable for operating on our available and legal frequency spectrums. It's different, world wide. Link to comment Share on other sites More sharing options...
Members boseengineer Posted February 19, 2007 Members Share Posted February 19, 2007 2.4GHz tend to work in most countries (as long as you stay within the local radiated energy limits) But that makes this band very crowded. Most cordless phones and home networks (802.11b and 802.11g) sit there and compete for bandwidth. Link to comment Share on other sites More sharing options...
Members Gregidon Posted February 19, 2007 Members Share Posted February 19, 2007 I learned something interesting in class the other day. Do you know why the 2.5 GHz band is nearly universally available world wide? Microwaves! Before all the fancy encoding schemes, spread spectrum and frequency hopping and the like, no-one wanted to use a radio on a frequency where people owned several hundred watt transmitters. Anyway.... just thought it was an interesting bit of knowledge. Link to comment Share on other sites More sharing options...
Members stompinne Posted February 19, 2007 Author Members Share Posted February 19, 2007 Seems like the brand is not familiar in the Americas, or do i understand something wrong? In Europe is most known for its speakers. Link to comment Share on other sites More sharing options...
Members agedhorse Posted February 19, 2007 Members Share Posted February 19, 2007 Where are you located. If in Europe, then maybe it makes sense. If you are in the U.S. or Japan then you may run into issues. The 2.4GHz band is full of stuff, low powered drvices can get lost in the mud.

Members agedhorse Posted February 20, 2007 Members Share Posted February 20, 2007 Now the real question... if you are not expecting too much, then why bother with wireless. Seems odd to buy something without expecting it to work well eh? Link to comment Share on other sites More sharing options...

Members Balladeer Posted February 21, 2007 Members Share Posted February 21, 2007 I use some low-end Shure VHF products, so the I offer the following comments that may apply to other brands. VHF range is nominally 100m, but signal quality degrades quite markedly. Don't expect great results at more than 50m unless you have a completely clear line-of-sight. That's right - bodies and other objects can mess up the VHF reception. Metal things - music stands, chairs etc, will really block it. If you go for a system like this, keep the receiver/aerials as high as you can. I improved things greatly by swapping the little twigs for longer antennae. And keep the mic batteries fresh - the RF degrades before the audio in my experience. Low-end systems are fixed frequency, and not generally user-adjustable, so you need to be sure that you're the only one using that frequency locally. Realistically, you won't find that out until your first really important live performance! On the subject of audio, I suspect the low cost will be down to the actual mic capsule used. My system has an SM58 head, but dB's cheapest is a no-name. I note that some systems from dB Technologies use Beyer mic heads, so check these out against reviews of those mics. Hope this helps. Remember, in this life you always get what you pay for, usually a little less. Link to comment Share on other sites More sharing options...
