obbm Posted July 24, 2007 Share Posted July 24, 2007 (edited) With the proliferation of Bluetooth enabled products that support the A2DP protocol it would appear that it should be possible to put together a simple and cheap in-ear monitoring system. I recently managed to obtain a couple of Sony Bluetooth bits. A pair of DR-BT10CX stereo headphones and a TMR-BT10 Portable Stereo Transmitter Transmitter has 3.5mm stereo jack and connects to any headphone output. Both rechargeable, both very small. Once paired they work faultlessly over a distance of about 20 feet. With a PC or an iPod I thought the quality was excellent and it handled a direct feed of a bass with ease. My mind immediately leapt to the idea of a Blutooth enabled bass so you could Bluetooth send to the amp and Bluetooth receive from a monitor system. Alternatively you could pair the headphones with the bass for practice. All technically possible. There is however one big snag, and it is a big one. The digital processing puts in so much latent delay between plucking and hearing that playing becomes impossible unless you like playing a long way ahead of the beat. Pity. I quite fancied a Bluetooth enabled badge on my basses. Edited July 24, 2007 by obbm Quote Link to comment Share on other sites More sharing options...
ped Posted July 24, 2007 Share Posted July 24, 2007 very interesting. used in conjunction with a pod you should be able to cut the latency, or are we talking several seconds here? funnily enough i saw the thread topic and thought you were after a cheapo in ear set... i was about to say can't you pop into yer shed and rustle up something! i should have known!

Alpha-Dave Posted July 24, 2007 Share Posted July 24, 2007 Dave: do you mean that for a double conversion - bass to amp, then amp to ears - the delay is too long, or that even in a single conversion - amp to ears - that it is too long? Simply because a cheap in-ears system would be brilliant even for a start. Quote Link to comment Share on other sites More sharing options...

Trying to play along with a drum machine or a disc is impossible. Shame. ped - I don't think even a pod can give negative delay. You are asking for the string to sound before you've plucked it. Edit - opinion on the web gives the audio delay through the system as 1/2 a second. Edited July 24, 2007 by obbm Quote Link to comment Share on other sites More sharing options...

Live TV will be a thing of the past when analogue switch-off happens because it will always be delayed. Long live analogue. Quote Link to comment Share on other sites More sharing options...

Well we are in the digital age and the analogue dinosaurs will get less and less. I can hear a delay in my wireless though most of the believers will tell you there is no latency.

WalMan Posted November 13, 2007 Share Posted November 13, 2007 If you are talking of cheap in ear monitors then a long while back before we got the proper bits my vocalist tried using a cheapish FM transmitter he got from the US in conjunction with a walkman sized FM radio & earphones. It wasn't the greatest, but I suppose one might try something similar with the little FM transmitter packs you can get nowadays to feed an iPod into your car stereo if you do not have a dedicated link in the car? Mind you I don't suppose that would work much better, but you never know. Quote Link to comment Share on other sites More sharing options...
