Back to work for the next 7 days.  All experiments will commence after that.

The left speaker is not working.   :scratch: :scratch: :scratch:

Only right top section - still no BASS.

I am using one set of pre outs for speaker section and second set of pre outs for the amp plate. 

My brain cannot think anymore.

Sunil, you did not take my advice to get the panels running first.. Turn OFF the bass amps, play music, and be sure both speakers are playing midrange and treble.. Only then should you bother with the bass.. Another clue--turn OFF the main amps while you're making sure both bass systems are running.

EDIT--Also, make sure you have signal at both outputs of your pre/pro.

Some starter settings I recommend are:

PEQ - Off.  We'll come back to PEQ later, for now just leave it in the Off position

Delay/Phase - set to 0

Crossover - set to 120

Volume - we'll have to measure this before we set it.  Leave it alone for now.

Line in/Lowpass - set to AVR/12

Rumble Filter - Off (unless you have a turntable, then set it to On)

Extension Filter - 14

Damping - High

The first thing we need to do is to measure the main panels and bass SPL together so we can match the sub volume to the main panels volume.  Do you have way to do acoustic measurements?

If you don't have something already, I recommend using an app on your phone to do the measurements.  Let me know if you want more details about the program I use.



Super helpful. Thanks Tyson!

Super helpful. Thanks Tyson!

The crossover point can vary, based on your room.  In my basement the panels drop off at 120.  But in my living room they drop off at 90.  Something to keep in mind.

Can you provide some pointers on how best utilize PEQ?

Sure thing.  My recommendations for setting up PEQ

1. Measure the bass response in your room. 
    - Download a program on your phone that can do FFT measurements.  I have an iPhone and I like AudioTools by Studio Six Digital
    - Run pink noise through your system.  The pink noise lets you get a full range measurement of your speakers in your room
    - Look for bass humps in your FFT measurement
2.  On the PEQ set the "Frequency" dial to whatever bass hump is the worst.
    - Note - ONLY use the PEQ to reduce a bump.  NEVER use it to fill a hole.
3.  On the PEQ set the "Bandwidtth" to the 10 o'clock position
4.  On the PEQ set the "Gain" to -10.
     - This one you should play around with to see what gives you the best response. 
5.  Run the pink noise again and re-measure your system and now your biggest bass hump should be better
     - Play around with the "Gain" setting to dial it in fully.

Hope that helps!

Reconnected all the cabling after powering off everything.  Bass amps remain without power.  Playing music  using oppo player and ls100 preamp.  Speaker section works on both side - however low volume.  Didn’t power up the amp section.

'The amp section' of what?  Does that mean U didn't connect the speakers to a poweramp or poweramps?

And 'low volume' means what?  That U didn't or couldn't increase the volume?

Your notes confuse me.
