Bass/Treble balance on Bose Lifestyle 5

The bass on our home entertainment system is really dominant -- the room shakes but we can hardly hear the voice center channel.  We have tried amplifying the center channel with a separate speaker.  What I really need is a simple balance control to lower the bass on the big woofer unit.
Anybody know how?

    Sorry, this is a Lifetyle 5 -- it's an analog Bose system that predates the ones with online menus....

You need to go into your menu and set the "MOVIE EQ" to your liking. That is where your bass/treble balance is on a Lifestyle system.

Live Mix - Kick Drum

I go to a lot of live gigs where the mix is all "there" but it lacks overall.<br /> <br /> Most engineers I find underestimate the importance of a really solid kick sound in their overall mix. The audience, while probably not knowing why, will respond much better if the kick drum has real presence.<br /> <br /> There is a simple way to do this:<br /> <br /> 1. Boost the Bass (as far as you can push it without clipping or "*******" for maximum "RUMBLE" )<br /> <br /> 2. Cut 315htz in the low mid (this is the "BOOM" sound, bad for a kick, fill it with Bass guitar)<br /> <br /> 3. Leave Hi Mids flat<br /> <br /> 4. Boost treble for good definition (The "CLICK" sound)<br /> <br /> 5. Build your mix around this. I like to have it up far enough so that you can feel the kick drum as well as hear it but not much louder.<br /> <br /> I will leave most of the other drums flat unless the toms are too boomy in which case I cut a little of the low mids in them. You can also add a bit of extra 2000htz to the snare for more "crispness".<br /> <br /> Remember a good live mix has a good wall of sound:<br /> <br /> (If youre going to boost, boost these approx frequencies depending on the room)<br /> <br /> Cymbals 5000htz-20000htz<br /> Snare 2000htz<br /> Vocal/Horns 500-3000htz<br /> Guitar 300-1500htz<br /> Toms 300-500hz<br /> Bass 100-400htz<br /> Kick 20-200htz, 5000htz-20000htz<br /> <br /> Another simple mistake is not having headphones, I see this all the time!! You need them to isolate channels so you can quicly find out where any unexpected problems/noises are coming from.<br /> <br /> Don't forget to have EQs on all your AUX/Monitor sends and Front of House to cut feedback!<br /> <br /> Hope this can help out any engineers starting out.<br /> <br /> Thanks,<br /> <br /> Doomface

I just connected two sets of 901'a to Sansui G901 receiver. The sound is TINNY no bass at all. I've tried different connections and nothing seems to work. I've used two different EQ from bosse series

Either there is NO bass on the recordings (if you listen to it with headphones does it have bass?)'ve wired them out of phase. Connect only one(1) Bose 901's to just one side. Is there bass? Then connect the other side. IS there bass? If not reverse the phase (+ /- connections) and see if the bass comes back. Once that is done and there is BASS, then add the 3rd and then the 4th speaker. .Are you sure your Sansui can handle a lower than 4 ohm load???

Thanks for the answer - If we have 3 controls as Bass, Mid and Treble. If we keep those in 12 O Clock position, will the output level be equal. In using the Bass and Treble control only (if we have...

If all are in 12 o'clock position they are "flat" (nothing has been added or subtracted foam input signal) If you only have bass & treble, yes adjusting will affect "mids" but Mids change can go both ways dependent on increase or decrease of Bass and /or treble. By increasing bass you will pull some mids up also. By increasing treble you'll subtract some mids.

In most of the Amplifiers we have only Bass and Treble control (Bass works on 100 HZ and Treble works on 10KHz - approximately). In some Amplifiers we have Mid range control also. What is the frequency...

The frequency of mid range control is about 1KHz. The bass and treble are usually enough to set the tone of sounds and music, and if the customer has high quality speakers connected to the amplifier it is almost unnecessary to modify any tone. In my opinion you are right that x-band equalizer became less important now.
Thank you.

Bass and treble controls

You should check the Direct button is pressed or not.
In Direct mode, it by passes the treble and bass circuitry so you will not hear any difference even if you turn it.

We have just installed a Bose lifestyle system, with SA 2 and SA 3 amplifyer, with a second set of speakers in another room. we cannot get sound to the second room. the second remote is not responding....

Make sure you unplug your sa 2 and sa3 amplifiers after setting the codes. Wait at least 60 seconds, then plug back in. I would also unplug the in and out boselink cables as well. Once youve waited for a minute, then plug everything back in. Should work. If not, call Bose technical support. They are really great. I have 15 SA 3 amplifiers throughout my home. They are great.
