But when its playing a CD its loud and absolutely crystal clear. I have a C90 connected to a 4000x DSP with a fibre optic cable (this is for the CD) while a UTP RCA is used for the radio. Any suggestions on how to get rid of this....is it a bad ground on the deck? BTW after I changed decks from my previous clarion headunit it the radio got worse. ________________________________ Message 3 _____________________________________ Time: 10:48:21 AM PST US From: "Lord Dremgragen" Subject: Re: XDP4000X-List: Why are CDs loud but not my radio? --> XDP4000X-List message posted by: "Lord Dremgragen" From my experience, the signal strength of Sony tuners is pretty weak. I had a CDX-C7850 before I upgraded to my C90 and it got KILLER reception, but was still never very loud compared to my previous tuners I had -and of course not as loudcompared to CD. The C90 is just not good for radio I've decided. I replaced my antenna and I also tried grounding the C90 in multiple spots to get better reception and it never happened. To compensate for the volume loss, I turned up the gains on my amplifier just slightly. Otherwise I'd have them set at 4V. This lets me get reasonably loud with the radio. And then I just be careful not to turn up the CD volume to max. I also have displays for each amp that tell me if they are clipping, so I can monitor the output and not have to worry about hurting my speakers. You could always use your4000X in conjunction to weaken the CD signal if you ran the gains a little hotter. Just make your RCA output weaker on all of your presets except maybe one that you call "Radio." Just an idea if you're really having volume problems. -Brody Z.

When they reprovision the line, there will be an outage requiring that the local router here be restarted. It is also unclear whether or not the physical line will support the new rate, so some testing will be required to verify the new service at the time of installation. Unfortunately, I don't really have an idea of exactly when they will be reprovisioning the line, so I wanted to give everyone a heads up on what's going on. All Matronics List services such as email list redistribution, subscriptions, and web search and browse will be unavailable during the upgrade. In other upgrade news, last Thursday, 3/13/03 I upgraded the firewall appliance between the Internet and the Matronics systems. This new firewall represents a substantial increase in performance and hopefully reliability over the previous system. It will compliment nicely the new level of ISP connectivity. Finally, these are just two examples of the upgrades brought to you compliments of the 2002 List Fund Raiser. A special thanks to all that made a Contribution in 2002 and so far this year! Everyone that uses these Lists appreciates your generosity! I will post a short message again if I manage to get some clear direction on the time-frame for upgrade, or perhaps when its been completed. Thanks again!!

They have a telephone-jack that you use to connect the RSD to the amplifier. The RSD shows power on, protection, independent left/right channel clipping sensors, and features a LO-P switch/light. When you turn LO-P on (stands for Low Power), when the amp clips it halves the amplifier's output. This helps save your speakers if you induce clipping. -Brody Z.

Thanks in advance. > try this blower fan from RS: http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&category%5Fname=CTLG%5F005%5F007%5F014%5F000&product%5Fid=273%2D199 part#: 273-199 in case the link doesnt work... if they are in an enclosure, you can make an inlet and outlet vents and use 2 in a push-pull config... also, RS sells a horizontal design so you make the vent a slot, like a 1"x6" vent. i couldnt find it online but i remember seeing in a store... -- ----------------------- Leo G.
