Unlock the sound settings lock

What do you by setup for? Are you looking for certain settings to get a certain sound? I'd do a search for the player's name + amp settings. I would try the tone controls first if I was trying to tailor the sound. Try to adjust treble bass, midrange, and try with the volume down and the tone controls all the way up and reduce from there.

The bass and treble controls (as well as volume) have no effect on the recorded output if you're using the traditional jacks a tape deck would use. Only PRE-OUTS get massaged by sound controls.

Even if you DID affect the recorded signals, WHY are you using such exaggerated settings? Or was it by mistake?

In theory, passing the modified output back through the same controls (set to Minimum this time) would undo most of the unwanted effect. Assuming their precise and mirror image for gain and loss.

I had the same issue with my AS100D. When I first bought it the treble knob on the top channel was very responsive. At 10 is was unbearably "trebley". I was getting plenty of "high" treble set at 2:00, even 1:00. Then after about 6-7 mo, I started to feel it the brightness was leaving the amp. I was now putting my treble knob all the way to 10 and keeping it there, and it still wasn't enough. I had it serviced twice, no solution. Marshall got into the act and after months of going back and forth, they finally replaced the whole amp with a new one. I just got it. The treble was incredibly bright at 10, just like the former unit. But now after just a couple of days, I can already see the treble knob is not as responsive. I can't believe it! Now what?

No, Tone controls are on the front of the unit only. If your passing video thru the unit you can go into the setup menu from the harmony and adjust all the sound parameters that way "on screen" The only "EQ" capabilities are for the Center channel only. You can adjust "speaker size". "Large" setting will give you a little lower response. "Small" will crossover the speaker at "100hz" That's about as far as tone adjustment goes on this unit. Hope this helps

Only parametric EQ OR Bass/Treble can be active at a time. There is a option to set which one you want, refer to manual. Follow this- Adjusting Sound Setting Mode (long press "sound-mode" button) -> EQ SELECT-> select either P. EQ or B/T

Bass and treble can be adjusted via the sound menu only when the z-enhancer is set to off.

To change them while the Z-enhancer is on (B-Boost, Excite, Impact) choose the enhancer mode, then press the play/ent button. You can then use the up/down arrows to adjust bass and treble to -3 to +3

I ran into the same issue and was stumped at first. Then I noticed somehow I had changed the sound processing to "Direct" which meant the signal coming from the source was bypassing all of the control in the receiver. All I had to do is select another option (press stereo for example on the remote) and kick it out of the direct mode.

Use the high gain channel. Set the bass to 8-10 set set the mids to 6-7 and the treble to taaste to cut through. Also turn the contour all the way up. To gice that scooped mid sound. Or use the celan channel on the amp and run a boss metal zone pedal through it. Set amps clean channel EQ to flat ( at 5) and the metal zones controls. Treble to taste for a good bite, bass up to the point were it wont fart out on your amp, sweep the mids outer knob set about 5-7 and the inner knob to about 4. Set prescence for clearity and the distortion level as high as you can stand it.

An equaliser is, put simply, a more complex tone control, giving you the ability to cut or boost more specific frequencies than a tone knob, or bass & treble controls.

It comes in handy for tweaking the sound from your hi-fi to just the way you like it. But beware, as it can make your hi-fi produce sounds that are so bass or treble heavy, that you can damage your speakers if you're not careful.

Adding another compnent into the chain (like a graphic EQ) can add a little background noise but this Technics EQ is a pretty quiet one & you probably won't notice the noise apart from when there's no music playing & you've got the amp turned up high.

May i suggest removing the equilizer unless you can adjust the settings for each amp seperatly. The amps themselves will allow you to add bass boost and treble boost. I think the problem your having is trying to run to much bass through your system causing it to distort badly.
