I tried to update my firmware last night.. What a disappointment, where is the bass??? Is there any tweak to set to put it back where it was? On the 2014.07b it was fantastic, on the latest, horrible like i lost every good thing

Anyone else experienced the same? Configuration is for stereo, so no sub/small setting for speakers.

Thank you

Configuration is for stereo, so no sub/small setting for speakers.

Do you mean it is currently set to small speakers? If so you need to set to large if you do not use a sub.

I had previously updated firmware versions and noticed that some of my previous configuration was reset to defaults so needed to re-apply my settings manually.

Hi BrystPlug,

A previous (old firmware) bass levels were too high and were adjusted down to conform to Dolby and DTS certification requirements.  If you need to adjust bass levels back up, it can be done through the menu:

SOURCE SETUP-->SPEAKR LEVEL-->SUB (up to +/-12dB)

That is per source. Bass and LFE can also be adjusted globally in SYSTEM-->SETUP-->MISCELLANEOUS menu:

BM DITRIM   (range -40 to +22dB, this is Bass Management LFE Digital Input trim)
BM AOTRIM   (range -40 to +22dB, this is Bass Management Analog Output trim)

BM DITRIM applies only to SPDIF,Optical and HDMI sources,
BM AOTRIM  controls the analog SUB channel output level.

Was it before 2014.07b ? (The old firmware) it was on this one, the bass in stereo was superb, upgrade to latest firmware and voila, no more bass. Thanks for guideline in the menu!

There was a bass adjustment 13.5dB up for digital and hdmi inputs in rev 2014.05 and 06b, (which was excessive)  then there were adjustments correcting it in rev 2015.04a
