Default Sound Quality Question And Home Unit Question...

Hi, I am a new subscriber and I have a few questions. First of all, the variety of music and everything sounds great, and for that I am very satisfied, but the quality in the car is not too great. The sound not only sounds tinny but there is static on silent or low parts of songs and on DJ introductions with no music bed beneath the voiceover. Also, the sibilants, or "s" sounds, are not clear. I tried listening on the XAct boombox at home and it sounds fine, and has no static or anything. The "s" sounds are crisp and clear as well.

Another question: the XAct radio unit gets very hot when running for extended periods of time. I was just wondering if anyone knows why this is and if the heat could damage the unit. Thanks!

Looks like as the time approaches we are going to get a lot of Howard Stern converts on the stream.

"Welcome to the stream, it is by the stream alone I set my mind in motion."

If you are using the fm modulation in the car, chances are FM bleedover from local stations are causing interference. Search the Install Garage for the term SATSWB or Auxillary (aux) connection - the better choice.

//EDIT Man those Xact units are cool. If I had known about them a few month ago when I signed up....

The thing is that Circuit City installed a thing to help block out the FM signal. The XAct model that I have had a plug that was too big for the Sirius SATSWB connection so they used an XM one that they said they use all the time for Sirius radio units.
Anyway, I just looked at the setup for it and noticed that there are three inputs on the thing that you plug into the bottom of the receiver: a DC power jack, an audio jack, and an antenna jack. The DC power jack and the antenna jack have wires plugged in but the audio jack has nothing. Could this be part of the problem? Also, is there a reason why the XAct unit runs so hot?

That means you are using the FM transmitter in the unit to transmit a signal that is being picked up by your car reciever. They used a different SATSWB to connect your FM antenna of the car radio to the Xact.

The units I have seen all run hot, so I assume the Xact used the same radio circitry. If it bothers you look at some user mods in the intall garage where external fans have been added. I run mine all day in the car and the heat issue seems ok. Although no one would argue that a cooler ic circuit is a happy circuit.

I don't use a SATSWB so I don't know if changing the channel will help. But it won't hurt anything. Hey maybe you can take another radio and tune it to see if you get the same issues. Could be your FM modulator or the connection isn't clean in the switch. Or you are just an audiophile that hasn't come to terms with the limitation of FM. ---- that's a joke.

Bottom line though if you love sirius look for a aux adaptor for your car stereo or have circuit city see if they can install one for you.

no changing the channel with the SATSWB will not help. if you had a SATSWB you would not be getting any static. it would have disabled your AM/FM antenna and would be taking audio from your XACT unit instead. i would take it back to the installer and complain because they did NOT install a SATSWB if all you have plugged in is sir antenna and power. ive heard alot of people lately saying they had someone at BB or CC install the SATSWB but did not have anything plugged into the fm out port. what are these installers doing?

*EDIT*
oh btw which XACT unit are you running?

This is exactly what they used:

http://www.circuitcity.com/ssm/Delph...oductDetail.do

Is this the wrong one? Is this even a SATSWB connection?

i dont see how they could have thought that would work on an XACT unit or any unit other than a skyfi2. it looks like it has the skyfi2 connections(im assuming that those are skyfi connections because it says its for the skyfi). This is a SATSWB. maybe print this pic out and take it to the guys at CC and make them install the correct thing. im guessing what they did was hook that box up between your am/fm antenna and your stereo and didnt bother connecting it anywhere else and they thought that would block out FM. idiots. BUT im not sure what XACT unit you have so i dont know if you can use the SATSWB but you should be able too.

Well this is just fucking great. I'm going to go down to Circuit City right now and see what the hell is up with this. It clearly sounds much better on my home unit and I don't know what the hell these guys at Circuit City are doing selling the wrong modulators to people.

Learning queation:

So the SATSWB takes the audio output from the receiver and modulates it? Why not just use the FM out and an in line antenna coupler? But hey at 19 bucks who cares right?

After seeing that link DarkSpoon posted I have to also say WTF are they doing over there?

good they need a kick in the ass. maybe they will actualy learn a little bit about what products they sell (doubtfull though). atleast you will get your problem fixed.

well you would still get bleed through because you would be getting fm from two sources. the black box on the SATWB is a switch. it turns off your AM/FM antenna when your sirius unit is on and vice versa.

Cool. It eliminates external reception completely. Perhaps Circuit city either didn't have the correct one in stock or they are correct at saying the Sirius one doesn't fit into the space and this sky fi one does. It would be simple to splice a mini audio connector on there (assuming it's a special OEM Delphi one currently) Perhaps they just forgot to hook it up to the audio jack? I guess the switch detects the line level and actuates a relay? That means it also must have power so perhaps they forgot that as well. Bottom line the Fckd up eh?

the SATSWB doesnt have any direct power connections. but yes it detects the line power from the unit and actuates.

imo if i have a place like CC installing my hardware they shouldnt be splicing anything. i mean they cant even see the difference in a skyfi2 and the XACT unit. but yeah they screwed up 100%.

I was about to go to Circuit City and see what's up but before I did, I decided to call Radio Shack to see if maybe they could give me some advice/answers. It never ceases to amaze me how these electronics stores hire nimwits to answer technical questions, and Radio Shack was no different. I spoke to some girl who had never even heard of a SATSWB; she went as far to suggest that my "speakers don't have enough wattage". Sure they don't, honey, that's why they sound perfect with everything else, right? Best Buy didn't know much either. To be honest, I'm not even sure I know what the problem is anymore. Do I need an FM modulator or a SATSWB? Are those the same things?

Update: I called Sirius and they said that that FM modulator that Circuit City sold me is fine to use, I just needed to put it on a station that has only static to prevent all the bleedthrough. The "s" sounds are still a bit unclear though, which is why I'm going to Circuit City now to make them make sure that all the wires and everything are hooked up correctly. Problem partially solved, I guess.
Also, regarding the hot temperature of the radio receiver, I was told to put the brightness down a bit, and it seems to have worked, but only time will tell for sure.

Turning down the brightness? Damn I guess those LCDs require a lot of voltage like the old school one's used too?
