Laptop Audio Quality

Postby amelianydia » Tue Sep 06, 2011 2:24 pm

This was originally posted on the Wiki Meetinghouse Technology Feedback page. Has anyone else had similar problems? Are there any other solutions to this problem?

"Our stake presidency and ward leaders frequently use laptops. In addition to the projector connection, they often want laptop sound output fed into the chapel sound system. The DL-10 box works, but it's a challenge to explain and adjust. I would appreciate a dedicated device that has a stereo plug (for the headphone jack of the laptop) at one end and an XLR plug (to a microphone input of the sound system) on the other, with an internal balun (a transformer to convert the unbalanced laptop audio to balanced audio for the sound system) and simple resistor mix/pad to attenuate the audio by a fixed amount. Note that I have intentionally omitted any variable resistor. For usage, we hand them one of these devices, tell them to plug in the two ends as described, and have them set the volume using their laptop volume control software. No muss, no fuss!"

We have a pair of ART DTI boxes which do pretty much what you want to do.
We got them from: http://www.bhphotovideo.com/c/product/381596-REG/

If you request, your FM group can order an EMtech EJ-2 which is exactly what you want (have them order it as they get 50% off of the website list price).

Yes the EJ-2 will do the trick, another option is to request to have an Emtech MSC-W added, they have been putting these up on the side of the pulpit for many years whenever the sound system is replaced.
