Ray & the Group, This is exactly what we have done in our offices.
We have used both Rio 600's and 800's. We use a 1.5v wall wart from Radio Shack. I soldered wires from a small jack to the battery compartment, and attached a corresponding plug to the 1.5v wall wart transformer. Our original system has been running, non-stop, for almost 2 years. We previously used a CD changer. This doesn't store as quite much music, however we never have anyone on hold for more than 3 or 4 minutes so you shouldn't need hours of music. Unlike our CD changer, it never has any lockups. The wall wart is connected to the UPS, so power blips don't turn it off. ( We use classical music that is royalty free, BTW...) As far as software, once you have the MP3 files created, we used Real Audio's Real Player since it supports the Rio devices out of the box.

They're inexpensive now -- refurbished ones are going for about $40. The output level is perfect for the KX-T's. I have used them on KX-TA624's and a KX-TD308. The output is stereo so you might want to make a cable to combine the 2 outputs into a single mono channel. The players have 32 Mb of memory. I loaded them with over an hour's worth of music by converting the source to mono and then using a 24-bit/sample and a 24 kHz sample rate. The resulting file size is about 220 kB per minute of audio. The frequency response rolls off at around 6 kHz, but that's more than adequate for telephone quality-- An hour's worth of music takes up 15 MB, so there still enough memory to load about another 45 minutes' worth. The player runs from a single AA cell, and I stole the power from the KX-T using a LM317 3-terminal adjustable voltage regulator. Understandably many installers are reluctant to dig into customers' KX-T's, so a wall wart power supply could be used instead. You need only a few milliamps. I've never seen a 1.5 volt wall wart, although I'm sure they exist. 3-volt units are easy to get; you'd just need to put a dropping resistor or regulator in the line. The RIO 800 is perfect for this use. It's all solid state so there's nothing to wear out, the power requirement is miniscule, and it can be set to play continuously, either sequentially or random. You can even lock the controls. The hardest part is loading it up with the program material. You need a PC with a USB port and software that can create MP3 files. I used Ahead NeroMix, (http://www.ahead.de) which lets you copy tracks digitally from an audio CD and convert them to MP3. However there are plenty of other MP3 programs available. Have fun! _________________________________________________________________ KX-T Mailing list --- http://kxthelp.com/ Subscription changes: http://kxthelp.com/mailman/listinfo/kxt multipart/alternative text/plain (text body -- kept) text/html _________________________________________________________________ KX-T Mailing list --- http://kxthelp.com/ Subscription changes: http://kxthelp.com/mailman/listinfo/kxt
