Sub/TV

[moreira85]

i ran through a long thread that user zumbo helped me out with in the past on this topic, my setup is correct, i am using the xover from the reciever, set to 60hz, all speakers set to small, bass set to sub, crossover on sub is disabled.
ANYWAY, i wanted to know if everyone else experiences this.
my boston sub rocks when wathing dvds/movies, however when i watch television i get very very little activity from my sub???? i know that the sub is enabled in 2 channel stereo mode when i watch tv but dont know why it is not very active almost seems like it is not even on , is it because there are not many lows that are coming out of the tv signal and does everyone else experience this????? i have the sub volume set at about 11 o clock ( which is a setting of 5) on the sub and the sub level on the receiver set to -3.5.

What happens with the sub when you play a CD with some good bass content? Have you tried a DD prologic processing to see what happens with the sub?

What is the video source for the TV ie dbs, ota, cable, sd, hd? Some manufactures apply compression settings in their equipment that might need to be changed. Do you notice any other anomialies?

I get about the same amount of bass when I watch TV or movies but maybe because I watch HD TV and it is in DD?

I dont have a cable box or HD, It is regular standard cable. The coax comes in from the cable company right into my TV. The audio out is coming directly out of my TV and into my Stereo Via some RCA connectors.

when i put in a CD it is much better, yea i have tried switching the setting on the yammy from 2 channel stereo to pro logic and still very weak signal to the sub.

my 2 cents....

To experience good LFE content while watching regular TV programming, you generally need 2 things.

1. A cable box that is 5.1DD compatible.
2. Box must be connected directly to receiver via Digital coax/optical cable.

Aaaah..... that's why.

 

[moreira85]

buckeye, you think if i had a digital cable box and ran optical out to the receiver it would make a difference in LFE out?

 

[AVRat]

It may help your over all setup to decrease the sub's gain and increase it in the receiver to 0+ dB.

It seems you are getting analog audio unless you are subscribing to digital cable even without a box.
Try to increase the crossover in the receiver to its max setting, be sure that the receiver is set up to have a sub even in 2 ch mode, and increase the sub level at the sub a bit and see if this helps. Costs nothing to try this.
On my old TV I temprorarily used a bookshelf speaker when the internal gave up the ghost and it seemed like it had plenty of bass frequency in it, perhaps not the super lows, but then, I didn't try a sub and the speaker was directly connected to the TV through its detachable speaker connections, not interconnects.

 

[moreira85]

this would probably be a quick fix to adjust the level to max setting, but i dont want to have to mess around the with settings every time i switch between tv and dvds. i assume just wait until we get a new tv in our new house in a few months and subscribe to hd and and digital cable. the digitial cable should help with optical out.
WHAT SETTING DOES EVERYONE HAVE ON AVERAGE ON THEIR SUB? AT 12 O CLOCK POSITION, 9 O CLOCK POSITION???
CURRENTLY MY SETTING IS AT 12 OCLOCK AND XOVER IN RECEIVER AT -4.5. I MAY TURN DOWN THE SUB VOLUME SETTING TO 9 O CLOCK AND XOVER ON THE REVEIVER TO 0DB AND THEN SUBSCRIBE TO DIGITAL CABLE BOX IN MY NEW HOUSE. I ASSUME THAT THE DIGITAL CABLE BOX WILL PROBABLY GIVE ME AN LFE CHANNEL RATHER THAN AN ANALOG SIGNAL. (IS THIS CORRECT)?

Nobody else's levels are going to help you. Your room and everything in it make yours unique, as is everyone else's.

 

[ParadigmDawg]

You are correct but I have no idea what he is saying about the crossover; may be some confusion there.

Apparently the crossover in his receiver is set to that 60Hz. I was hoping to get him to check if he is getting any sub action if set to a higher crossover and with higher sub levels which would indicate low frequency activity in those analog signals and his receiver may be properly set up that the sub is activated in stereo mode as well. Some receivers need to be told that in stereo mode it has a sub also connected to it. It was all about troubleshooting and detective work to figure things out.

SORRY greg, i typed it wrong, i had just gotten in from going out for a celebration drink, we just had the ultra sound and its gonna be a BOY!!!!
ANYWAY, i mis typed, i meant to say i am going to try turning down the level on the sub dial, and turning up the level on the receivers sub level to 0db (i typed crossover instead of db level on my previous post, oops)

we watched the polar express last night, damn the train in that movie produces some killer lows. I had to turn down the pv 1000sub dial to about the 9 o clock position a setting of 3 as the house was rumbling away! there is no question that this sub rocks just need to figure out why it is so weak when watching tv, we'll just have to wait until we get our new house in the spring and try hooking up the cable tv digitally with optical out instead of analog and see if that helps.
to answer the other posters question the sub is assigned in 2 channel stereo mode because i checked the stereo db levels in 2 channel mode, and
center and surrounds have this symbol assigned to them -- meaning they are not assigned in stereo mode and L R and sub channels have -2db -2b and -4.5 assigned to them.
sorry for all the info!!!

 

[moreira85]

so here is the deal, i tested the sub today with dvd movies/ music/ tv in my home theater, then i took it upstairs to parents set up where i did the same thing.

dvd tracks the thing is sick, i only have to put the subs db to about 3. when watching tv or listening to music on cds it seems i have to crank it all the way up to 9 or 10 to get anything out if it. i would be curious as to what other owners of this sub have expereniences, i emailed boston acoustics and will have to see what they come back with.

This should tell you something if the setting needs to be that high with a CD as well, then it is not the TV.

Have you level matched with an SPL meter the sub to the other channels with an internal test tone in the receiver or a test DVD?

 

[moreira85]

no ihave not, i gotta get an spl meter as i dont have one, when i do get one i will be looking for input on how to do it, i did run the mic that comes with the yammy receiver though.
