Bluetooth adapter with digital input

I'm interested to purchase a bose solo tv speaker together with a bluetooth adapter so that i can play music from my laptop using the bose speakers. Do you have any bluetooth adapters that I can plug into the digital input of the bose speakers instead of the RCA input so that I can enjoy better sound quality?

Rocketfish makes one with digital but there are issues with it's range, Belkin and Harmon Kardon make them, but they're analog only.All of them are in the same $50.00 price range.
But the connectivity doesn't matter, you will not be able to tell the difference in audio fidelity between analog or digital using bluetooth.
Bluetooth simply doesn't have the bandwidth to carry any type of audio that needs a higher bandwidth digital connection. Digital Stereo maxes out at 1.41 Mbps, Bluetooth A2DP which is the best option for audio right now, maxes out at 768kbps.
There's a nice and consice article here that briefly goes over the technical details:

Monitors with Digital Inputs

What monitors are available that accept the Toslink input directly? Do the keyboard and on-screen volume controls still work with this arrangement?

I believe Tannoy make a set of the Elipse range of speaker with digital inputs as well. I have no idea why you would want to do this though. I suspect the gains in quality would be tiny if anything at all. You'd be better to spend more money on something less techy and get something that really sounds great!

Measuring Velocity with Digital Input

I am not very familiar with digital inputs and so am having trouble picturing this system. I will be starting from scratch but will have PXI chassis' available. I will have about 381 events. Event 1 will trigger acquisition, and over the next 10 - 20 ms, I need to capture the next 380 events. I don't need to know how long each event stays high, only the time in relation to the first event. I would like to catch any event that stays high for at least 1 microsecond.
Since it will require multiple chassis, I think I will just wire Event 1 to each chassis and so shouldn't have to worry about any syncing problems? A colleague has been looking at PXIe-6544 and 6545, but I'm not sure this is the right tool, and hoping there is a less costly alternative.
Hopefully someone can give me a kickstart in the right direction.

Hi Deskpilot,
If you're looking at separate lines, then my previous idea would not scale so well (each X Series card only has 4 counters). I like the idea of using an R Series board to do this and would suggest posting over at the Real Time Measurement and Control forum to double-check the feasibility.
If you had to do this with M/X Series boards, then the more efficient solution would be to use the Digital Inputs instead of counters. The R Series should be more elegant but I thought I would type up the suggestion for M/X Series anyway:
We have a few M/X Series Boards that have 32 clocked digital lines (48 digital lines total, but only 32 support HW timing). Depending on the board selection, you could sample the digital lines at 1 MHz (PXI 6224, PXIe 6323) or 10 MHz (PXI 6254, PXIe 6353). Then, in software you could determine which sample the rising edge occurs on and use this to timestamp when the event occurs. The two options would respectively give you 1us or 100 ns resolution.
The X Series (623x) cards have built-in timing and triggering for the digital lines. The M Series cards (622x) need to take in the clock from another source (you can use a Counter Output to create a 1 MHz or 10 MHz clock which can be triggered by your first event).
At 381 lines you'd require 12 boards. Each board requires 2 terminal blocks for access to all of the lines.
Again, I recommend looking into the R Series board for your task, I just wanted to post another solution in case somebody comes along with a similar issue but with a few less lines.

Synchronize analogue inputs with digital inputs

Dear fellows
I am using NI-DAQ, PCI-MIO-16E-4 (new name is 6040-E, I guess) with LabView 7.0. I am working on neuro-physiological signal acquisition. I have 16 analogue input channels and one digital input channel. Digital input is acquiring a TTL level signal that is a reference to the onset of a particular event. I want to synchronise both analogue and digital signals.
Any suggestion?
Nabeel

Nabeel,
have a look on following KB:

D-link bluetooth adapter with Nokia N70 problem

I bought a D-link Bluetooth adapter to sync my Nokia N70 with my iMac G5 (1st gen). Adapter is perfectly accepted. Paring with N70 goes well. Sending files: no problem. But: iSync says cannot connect to this device. I have all updates for iSync and MacOS X 10.4.6.
How to solve this? Any solutions or experiences much appreciated!
Frank

In my services field it says:
SDP Server, AppleAgent, Hands-Free Audio Gateway, Headset Audio Gateway, OBEX File Transfer, SyncMLClient, Nokia OBEX PC Suite Services, OBEX Object Push, Imaging, Dial-Up Networking, Salling Clicker
Paired: Yes
Configured: Yes
Favorite: Yes
Connected: No
Serial Port: Yes
Encouraged to play around again, I found out that while sending a file from a SE K750 i it appeared in iSync, while before it did not. I repeated the same with the Nokia N70: as soon I was having an active connection sending files and at the same time ordered it to add a device to iSync it accepted it.
Now bluetooth seems to be working, except for one thing. When I use Bluetooth to connect my iBook and iMac I'm able to send files, but I'm not able to browse the other computer. Again it say something about services....

Recommend a stereo with digital input

Hi All,
I recently received an Airport Express for Christmas and now I want to upgrade my stereo with something that has a digital input. Is there something that you can recommend that has exceptional sound and is a good value for under $300 (including speakers)
Thanks!

I find that all you need is a "Mini-plug audio input cable" (thanks Duane), and you can just plug your iTunes directly into your current stereo system via your Airport Express. Have you tried that? If so, have you experienced any loss in sound quality? Even though I love sound quality, I don't credit myself as an audiophile...

What Speakers with digital input?

Hi all, since with the nForce soundcard we now have decent drivers with proper support of 5.1, what set of speakers should i buy which use SPDIF ?

The 'purists' buy seperate systems because it 'looks' like you have a system.
Bollocks. You buy component Hi-Fi to be able to match each component to your exact tastes and requirements and be able to upgrade one component at a time.
If you want to 'look' like you have a system (whatever that means) it would seem to me that the integrated boxen you propose are the prime choice.
I don't want to diss all-in-one systems, they have their place in the market, but to suggest that they are by definition better than seperate component systems is nonsense. I can match a Pioneer DVD player to a Rotel amplifier and hook up ASW Cantius speakers, cause I know Pioneer is good at optical players, Rotel makes excellent amps and ASW makes top-notch speakers. Try that when buying integrated. On the downside, I'll end up paying significantly more money and having components that differ 10mm in width and use different color leds 'n stuff- it's up to me to decide whether that's worth it.

30gb ipod with bluetooth adapter?

i would like to use a bluetooth adapter with my ipod. im not sure which generation ipod i have though. i bought the 30gb when it first came out. which generation is it? i found a panasonic rp-bt10 earbuds and icombi ap21 adapter, but they say 4 generation or newer?
are these 2 accessories worth buying, will they work, or are there better alternatives?

so does the panasonic rp-bt10 earbuds work with the ipod classic? i was going to buy it but the add only includes the ipod 5th generation as compatible, and it does not list the ipod classic! if not, does anyone know of a similar bluetooth earbud compatible with ipod classic?

VI Logger: digital input?

Does the VI Logger software work with digital input, or only analog input?

Hi Zack, you can only measure analog channels, but you can use digital lines as triggers for analog lines

Measuring PWM duty cycle with Analog Input

Hello folks,
I have a NI 9205 module and was wondering if there was a way to measure the duty cycle of a PWM signal that I am generating with a separate microcontroller? I have found a lot of examples with Digital inputs but not analog.. Is this possible?
Thank you,
Bob

Hi Robert,
I'm not sure what that error is, try searching for it.
If you want to measure a PWM signal you would usually use a counter input. A counter is a dedicated piece of hardware that is used to measure digital signals. Since the NI 9205 is an analogue device and it doesn't have any counters onboard, you will not be able to select counter input.
I would recommend you get the right tools for the job and buy a digital acquisition device with an onboard counter. It will make reading PWM much easier for you. The NI 6008 has a counter onboard and is only £99. It will also offload processing from software to hardware since you don't have to calculate duty cycle.
If you still want to use analogue post back and we can look into why its not working for you. Tips to start you off: Voltage is the correct setting and Look in the manual and make sure you have connected it like you have configured it (differential, RSE, NRSE page 14)

How to connect Digital Optical Audio output iMac with Receiver Input

I have connected iMac with onkyo hts-3300 home theater system receiver through optical audio TosLink Cable.( http://www.amazon.com/Digital-Optical-Audio-TosLink-Cable/dp/B001ZU3G2I/ref=sr12?ie=UTF8&qid=1292865309&sr=8-2 ). Unfortunately there is no sound coming out from the Home theater system. I have verified the Receiver optical input is working fine by connecting with my TV optical audio digital out put and the it's working great. The only difference between TV and iMac is, on my TV, it has optical audio digital output and I can use this cable (http://www.amazon.com/Tripp-Lite-A102-02M-Digital-connectors/dp/B0002WPREU/ref=s r11?s=electronics&ie=UTF8&qid=1297320792&sr=1-1) to make it work. I can also verified my optical audio TosLink Cable working because I can see the red light coming out from the cable. So the only problem could be from iMac. I doubt I need to change the additional setting to configure iMac to use external optical audio setting instead of the buit in audio setting. Hoe can I able to do it? or my iMac(IMAC 21.5"/3.06/2X2GB/500GB/9400M-ITP
MB950ZP/A) doesn't support optical digital audio out put? I have follow this thread http://discussions.apple.com/thread.jspa?messageID=12769423&#12769423 and to my surprise which doesn't work out for me. I doubt that i need to change some setting, but when I got to setting>> sound I cannot change any setting. I was quite depressed aldy. Can someone answer my question as i m a newbie here. Thanks a lot

Thank you very much for your reply.
@Király : May i know how to Open Audio Midi Setup? Is this Audio Midi Setup is in the locatated in the Setting in Mac Snow Leapord OS? or how to locate this "Audio Midi Setup " in Mac enviroment. Is it possible to open this Audio Midi Setup in windows 7 enviroment also? I Just want to get the audio from my iMac in Hts-3300 onkyo home theatre. YOur help is much appreciated
@rkaufmann87 : Thank you very much for your sharing about this http://www.apple.com/airportexpress/ connection. for me what i understand is the digital audio output in airportexpress is the same as the audio out put in iMac in terms of details sepcs. So this airportexpress will only help you connect wirelessly to home theatre system, rather than waired connection. Other than that nothig much difference. So there is no point for me to spend extra bucks to attain the wireless connection. Unless the airportexpress have optical digital input, which i believe not. Correct me if I m worng, thanks

Hi, I try to conect Mac Mini from 2009 with my HD Tv Samsung F 6400 . With Mini Dvi conection and adapter to HDMI input in TV I got picture but not sound! I have analog cable from the phones out from mac but imposible to conect to TV? Can you HLP?

You really need a newer Mac Mini with a true HDMI output, because that Mac Mini's DVI output does not support Audio.
You might try a 3.5mm to RCA adapter
from the Mac Mini's headphone jack to the TV's audio input,
but that would require being able to select the Audio input in the TVs menu while using it's HDMI input.
Optionally you could also use an external 2.1 Speaker System or patch the audio from the Mac Mini to your home stereo system to enhance that older Mac Mini's audio.

How to acquire serial data on a digital input line with good performance?

Hello,
we have a performance problem with our realtime controller. Our objective is, to read a 24-bit long digital waveform from a digital input line. To do this, we supply a clock signal (236 KHz) to the PFI1 Line of our DAQ Board. On each rising edge of the clock, a new bit is set on the digital input DI0.
Our hardware which transmits the data, is triggered through a digital output from our realtime controller. On each edge on this output, the hardware starts a serial transmission of 24-Bits.
Everything works fine except the bad performance of our realtime controller. We want to acquire the 24-Bits in a 1ms timed loop. To measure performance we wrote a test program. In that, we only triggered the hardware and transfered the data to the realtime controller. The task which is doing this job, has a approx. CPU-Load of 30%, which is, in my humble opinion, very high. The task is not waiting for data or anything else! We have earlier implemented a control which is also using a 1ms timed loop. This control is sampling 2 analog input signals, 2 counters. Futhermore it's sending telegrams with CAN and doing many calculations. The strange thing is, this much huger program has a CPU-Load of 25%. Does anybody know where the problem is?
For the better understandig I attached our test-program to this text.
We're using:
PXI-8175 realtime controler
PXI-6221 Multifunction DAQ
Thanks!
Regards,
Crest!

Hello,
First of all 30% CPU-Load is normal because the DAQmx-driver needs a lot of resources.
In your programm you should place a wait (for example with 1ms) into the while-loop which causes
lower CPU-Load.
If this is not enough you should build your vi like in the following example.

Christian

When it was explained to me it didn't sound to hard of a task, I have no LabVIEW experience and the tutortial sucks.

StevenD: FYI, I did NOT give you the one star rating. I would never do that!

Well, this is an assignment, so it is probably homework.
Why else would anyone give HIM such an assigment, after all he has no LabVIEW experience and the tutorials are too hard for him?
This would make no sense unless all of it was just covered in class!
This is not a free homework service with instant gratification.
OK! Let's do it step by step. I assume you already have a VI with the digital indicators.
"...but have no idea where to begin".
open notepad.
decide on a format, possibly one line per indicator.
type the document.
close notepad.
open LabVIEW.
Open the existing VI with all the indicators.
(are you still following?)
look at the diagram.
Who made the program?
Does the code make sense so far?
Is it a statemachine or just a bunch of crisscrossed wires?
Where do you want to add the file read?
How should the file be read (after pressing a read button, at the start of the program ,etc.)
See how far you get!
