Multiple audio devices?

[DougieNZ]

Hi All. Sorry if this has appeared on here before, but I did do a search.

Is there a device you can buy that will allow you to run multiple audio devices at the same time? ie you can pug your iPod, Radar detector and phone in to the same device and have 1 output set of ear plugs?

For example if i want to play an iPod and then have the radar detector cut over the top if an alert comes in? What about a phone call?

Any help appreciated.

Yep, it's called a car

here's your answer just use 3.3 ohm resistors not 10k ohms

or use a proper bike intercom system with the appropriate inputs.

Yep, sounds like you are after Baehr. Comes in different levels, say two devices all the way up to about 5, then extra kit if you want comms with a pillion etc.

Baehr isn't too cheap, but Challenger Motors is also a good company (He does the comms work on the police bikes)

have a look at the starcom1 unit, sparxfly sell them in nz. best value for money around at the mo in my opinion.

So true, partially the reason why we get on a motorbike is to get away from things like phones, music, kids, GPS, etc etc

There must be a simple audio input-output device selector, try DSE.

Whats the reason for the 3.3 ohm instead of the 10K ohm?

Impedance matching.

The circuit as shown on the website is for mixing signals prior to feeding them to an amplifier. Amplifier inputs are very high impedance so 10,000 Ohms (10K) is a good number.

Headphones on the other hand are low impedance (around 16-32 ohms). If you were to use 10,000k then firstly the circuit would pull sfa current to drive the headphones and secondly the majority of the "power" would be dissapated by the resistor not the headphone speaker. End result no volume.

By using 3.3 ohms you get around both of these problems.

ahh, i see. Thanks

Nolan helmit with bluetooth.

do you need so many devices?
forget the ipod, listen to engine.
radar detector, put big red light next to your engine warning light (that'll get your attention
mobile phone (why the hell when you have just escaped all the bs would you want someone phoning you to tell you all about it)

see i just saved you $350 or time wiring up resistors

[NinjaNanna]

just found this could be right up the "normal" persons alley

wont work, you cant connect different outputs all together and expect harmony. thats a 1 in 5 out. 5 in 1 out will blow something. Question for poster #1, is cell and radar bluetooth?

[gixxer-king]

or how about 2 devices, 1 in each ear?
