The meter shows peak and RMS at the same time. Technically if you have the top LED peaking at 0dB you should get 0dB in your software. However due to some technical reason this isn't the case.
I seem to remember it has something to do with the master volume allowing for the combined level of all the input channels.

I feel your pain on this stuart. I have had this mixer for 3 months and EQ/Gain Levels seems to confuse me the most as well. Here is something I have tried and maybe someone can chime in and let me know if im giving out good info. When your trying to figure out the levels of the tracks start in the normal PGM1 and PGM2 cue mode where you will see both signals split into a mono cue. Look at the levels and adjust from there. My safe spot that seems to work good is to get them to +8 on the mixer which I believe is 2 yellow led's up. Then after you do that and you have both levels matched...while your mixing switch over to stereo cue to look at what your levels are and keep them up 2 yellow led's up. The stereo Cue is the important one to me as this is what everyone is hearing out in the crowd. If anyone has anything to add or share to help Stuart or myself please do so. Good luck to ya!!

The thing you have to remember about a digital mixer and signal path is that what you might have at 0dBu on an analog mixer is calibrated to something like -18dBFS to give the mixer some headroom in the digital domain.
The TTM-57SL has cartridge sensitivity options for the pre-amps doesn't it? Make sure those are matched up correctly for your phono cartridges if you are recording from vinyl (in the Serato set-up screen somewhere if I remember correctly).
Considering you are probably well away from the clipping point in the mixer - you can use your channel gains to push your signal up to something like +6dB on the meters without any real problems. Providing your material isn't too dynamic as to kick in the buil-in limiter.
I'm trying to think as to whether it really makes any difference as you are doing all the adjustment after the input stage anyway. Basically just keep your meters peaking at around 0dB upto 6dB and you'll be fine.
Normalise your files to peak at -0.3dBFS in an audio editor afterwards.

I did some testing:

Generated a 1 minute 440Hz tone at 0dB and played it through SSL with all knobs set to their mid setting (in SSL and on the TTM57SL).
When the meter is monitoring the cue signals, the first amber led (+4) is lit continuously. When one switches the meter mode to 'stereo house', the '0' led is lit continuously.
The output of this same test file via the TTM57SL's Line 1 (over USB) is also seen by the computer as floating at 0dB (again, when all knobs are centralised)

Wonder why there is a difference between the two modes and is this difference just a visual one?

Oh well, for now at least, I'll keep my cue signals peaking at +4.

I'd still also much prefer the 'old fashioned' simple vu meter, which has one set of trailing leds.

Stu, dont forget, all knobs centered does not mean no attentuation! Channel gains centered is not equal to 0db! I cant answer any of your other questions, sorry :-(

Thanks Steve.

I also now realise something else:
The channel meter mode (as opposed to 'Stereo House' mode) displays the summed input of both the left and right channels.
I had always assumed (I don't know why) that it was only displaying one side.

Things are starting to become clear.
Cheers

Stu, what difference does it make for you? Just curious.

I have had my 57 since September and I'm still confused by the meters. I'd also prefer standard metering. I now resort to bringing in tracks and gradually matching volumes live.

Is there any way that standard metering could be an option in a future OS? I personally would rather see the meters light according to the level at which I have the channel fader set.

well, after using the 57 for over a year I can honestly say that I love the meters! It is very nice to be able to see the peak and RMS levels at the same time. It's great to be able to accurately judge the overall loudness of a track, rather than just its peak level, meaning that the chance of bringing in a heavily compressed track too loudly is greatly reduced.


but that isn't standard metering. Standard metering for an individual channel is pre-fader but post-gain - moving the channel fader doesn't normally have any effect on a standard mixer's level meter (unless the meter mode is set to display the master output).

Have I misunderstood?

If you want the 'normal' metering, just ignore every LED other than the topmost one and that's your peak level (one which a normal meter shows)

what ever happened to using your ears...and reading the meters
.......????

that's far too fundamental...

Here is a question.

I own the TTM 56 and Love The Level Meters that would display!
I bought the 57 a while ago now and love it death except that it's now PEAK-HOLD


Is there any way to change that back to just peak? It's a fully digital mixer so I would think it can be done. I have messed around but to mo avail.

Can I ask you why you don't like the peak hold.

I personally like the way the meters work, I don't get all of the fuss. I can measure the individual channels to make sure they're not peaking, than switch it to house and make sure the signal going out isn't peaking. I don't get what is wrong.

Because I was used to the 56 and think it's more accurate!

Anybody?

Still nothing?

Sorry my english is bad!
I'm from Brazil and my TTM 57Sl whem i turn power on after few seconds don't show LED peaking meters, knobs of EQ and GAIN doesn't work, cue signals not working correctly and all leds in the mixer turn off.
my equipament is new.

Please anybody can help me?

Hey Tritan,

It would take quite a few people complaining about the LED readout in order for our development team to change it.

Thus far most users are happy the way it is.

What may be happening that after a few seconds attached to the mixer leds stop for modulating and equalization does not work as well gain Sensitivity of the channel
Another thing all the lights that indicate that some function is linked stop functioning

should be defect in equipment

Thanks Zach for the Reply.
I just miss the LED's on the 56 :(
Would this be a software option in SSL like house/master mix
Or would this be a firmware update for the 57SL?

lol now that i am used to the led meters on my mixer using a regular mixer seems almost wierd in that i have to get used to their interpretations of their pfl led's.
