Farrow Posted November 8, 2001 Share Posted November 8, 2001 Ok the SB Live has 3 outputs for 5.1 sound...I have them all plugged into my reciever...I want to know where it is cutting the signals for the sub output channel. My quintets cut out at 100hz...but the sub redirection on the live may be below that...so i would be missing from that crossover up to 100hz. ------------------ - arrow Quote Link to comment Share on other sites More sharing options...
eq_shadimar Posted November 8, 2001 Share Posted November 8, 2001 Farrow - If you are using the analog 5.1 channel outputs of the Soundblaster and running them into your 5.1 inputs of your receiver then there is no crossover. On a typical receiver there is no bass management in the analog domain. This is what people have been complaining about with DVD-A and SACD since these formats require analog hookups (becasue of copyright concerns) for their full potential. The newer DVD-A and SACD palyers are incorporating bass management for the analog output within the players. Bottom line is that in your setup you do not have any bass management and each output is seeing exactly what the sound engineer recorded. If there happens to be material on the main or surround channels below 100Hz you are losing that information. If you want to use the bass mangement in your receiver then you will need to use the digital output of the SB card.

Farrow Posted November 8, 2001 Author Share Posted November 8, 2001 The Live 5.1 cards' digital output jack can do double duty as the analog subwoofer and center output and when in Digital mode it now offers 3 SPDIF streams instead of 2. When its used with the FPS2000, DTT2500 or a stereo mini-jack to dual RCA cable it will still send out the front and rear output as the previous Live cards. When used with the new digital DIN input on the DTT3500 system it will offer also support 5.1 for games. The output is above 0.5V standard but below 5.0V and will not work with the Digital Output Module The analog subwoofer channel can be selected as LFE out (5.1 mode only) or as a mix of all other channels. Meaning that it makes a cutoff somewhere and sends the below frequencies out to the subwoofer-in on a 6 channel input. I can't find the specification anywhere! I emailed creative but have yet to get a reply... I also know that the new Audigy line allows you to select what frequency you would like as the cutoff. (I have provided a picture of this that is available at www.3dss.com) ------------------ - arrow This message has been edited by Farrow on 11-08-2001 at 04:11 PM Quote Link to comment Share on other sites More sharing options...
