Having heard his work over the decades, I can assure that He does know what he is talking about. During presentations like this, it would be nice to insert the screen image that he is referring to, thus enabling a clearer explanation of the process. Also, If a question or answer is offered, it would also help to restate said comment for the remote listener. I have used the same approach and understanding of concept for over 10 years with digital and agree that this is valid on all counts.

Hi Robert, i have met you twice in India. But, your explanation of consoles bulit optimsed to line level signal is the best i have come across. Three weeks back, i did my best to expalin to my team on the concept of dealing with a line level signal and mic level signal. It also explains why many programmed drums and synrhs sounded as they due low bit rate..

So, when is the signal at line level exactly... when the RMS at the input gain meter is properly set or when in addition to that the channel fader is also at unity?
@JeremyMedicina6 ай бұрын
You'd start with the faders at unity (initially) to ensure full resolution of the signals. Then, gain stage your signals to reach the "line level" of +4dBu (0dBVU on a voltage meter) by driving gain into the signal with the preamp. That's the "sweet spot." This level is roughly equivalent to 0dBVU on an analog voltage meter or -18dBFS on a meter within a digital environment like a DAW. Your signal's average should hover around this spot on your meters. Some meters--like those in some DAWs--show RMS. In that case, this is also where you could stage the signals, especially if you are working with any analog hardware or plugins. For live sound, you'll be looking to get weaker signals like a "mic line" boosted up to the +4dBu target.

This is fantastic information - I was puzzling between a DCA and a Subgroup to make this work correctly- I am having to run my Subgroup master faders quite low on the console (around -20 db) - Is this normal? Or is it perhaps that there is to much power in the PA itself, and this needs to be adjusted down?

what about the difference in voltage in Line level , Mic level , and Instrument level?
@dietbr00ksy6 ай бұрын
Someone correct me if I'm wrong but... Line level = ~1V (about 1V of signal) Inst Level = (basically anywhere in between) Mic level = mV (milliVolts of signal)
@JBF-GST-TandaАй бұрын
Line level = around 1 volts + low to medium impedance (from several ohms to about 1-2k) Mic level = below 50mV + low impedance (most are less than 300 ohms) Instrument level = high impedance(10k to 1M), the voltage varies - Passive single-coil guitars produces weaker signals, while active-pickup metal guitars and electro-acoustic guitars can pump out voltages close to line level

Forgive my ignorance here, but what is in fact the difference between a VCA and a "master subgroup" that he describes near the end? Are they just the same thing, but one is pre and the other is post fader or something?
@jacomeintjes97096 ай бұрын
Main difference between a VCA (called DCA on a Digital Console) is that on a VCA when you move the fader it is the same as adjusting all the Faders individually in that VCA group where with a Control Group you are simply just adjusting the master volume that's being sent to that Control Group. My problem is that many digital consoles only have DCA's and not Control Groups so you don't have the option. Unless a Matrix can do the same job?

@jacomeintjes9709 I have yet to see a digital console that doesn't have groups options available. Which console have you used that doesn't have this feature?
@garrisonaw2 ай бұрын
@@conorm2524 The Yamaha TF series mixer does not have subgroups. The closest thing you could do on those is send your channels to an Aux Send, and then use that Aux as a subgroup, and feed all your different Aux sends into a Matrix for output to the amps. But if you use your Aux Sends as subgroups like that, then you lose the ability to use them for more important things like stage monitors.
@conorm25242 ай бұрын
@garrisonaw So you can still use them as sub groups. Cool. Still waiting on the other guy to explain how "many digital consoles only have DCA's and not Control Groups"...
@JBF-GST-TandaАй бұрын
Subgroups are buses (sub-mixes) in which audio signals are actually merged and then regulated by a single fader, so it not only provides a collective volume control for a selection of channels but also makes it possible to apply public processing to them - For example, applying a general EQ for all lavalier mics of same brand to calibrate their frequency response and to alleviate feedback problems, or applying a general compression for all mics recording sound from a drum set. However signal from a subgroup cannot be routed to auxes - It can only go to the main stereo bus or to matrices. This could cause a problem if aux-fed signals are used. VCA's are batch-operation remote controls which turn down the volume of their member channels proportionally under command from a single fader. Signals from member channels of a VCA are still separated and never premixed, so all aux-fed things like FX's or monitors would work fine. However VCA doesn't allow the signals to go through the same process like what a subgroup does.

@cocofocan Жыл бұрын
I don't quite understand the last part, or I should say I don't see a scenario when using a VCA to turn an input down 20db is a problem for aux levels, If you do foh and monitors from one console, you most likely send your inputs to auxes in pre fader and if you are doing only monitors for example why not just use digital trim ?

I think part of it would have to do with any post-fader sends that would be affected such as FX or subgroup processing.

Scovill is not talking about Aux Pre problems for "Monitors from FOH" scenario, but for AuxPost sends feeding the parralell compression processing (ie. Parallel Drum Bus) that will be disrupted once you lower the VCA on the drumkit (AuxPost sends to DrumSquash compressor will be lower, under the threshold on the comp). Hope that all is clarified now 👋

I assure you Robert Scovill knows that he is talking about. He has forgotten more about audio than you will ever know. Not only does his artistic/mixing skills surpass most FOH engineers, I think you would be hard pressed to find a more "technically minded" person than Robert. Did you know that Robert is credited as the first person to use virtual sound checks and live multi-track workflows? (Something he started using back in the "analog days" while working with Tom Petty). You should really use Google to learn about the people you are criticizing before you post.....
