I don’t care.. keep bumping the thread so A&H sees it

They’ve already got a Signal Generator, Spectrograph, and RTA.. why not a tuner

[mangobobParticipant]

You don’t know me or my business.. I requested a tuner not your negative bullshit, dick

[mangobobParticipant]

Bumping this request – would love to have a tuner in the Qu series.. it’s one less thing to buy/carry/patch

It could be another option on the RTA screen and following the PAFL signal. The Fn key would cycle through: RTA, Spectrogram, Tuner

Which is better quality for recording main stereo mix bus from outboard mixer (via 100 ohm symmetrically balanced output)? Obviously not ST3 since it’s unbalanced. Hopefully someone from A&H can chime in on ST1/2 vs Line Inputs.

[mangobobParticipant]

I noticed the ST1 & ST2 inputs do not have this -10dB pad (if you look at the System Block Diagram you can see the resistors missing compared to the Line 1-16 inputs).

Is the ADC chip on ST1 & ST2 the same as Line 1-16? Or is there a difference in converters for the stereo signals?

[mangobobParticipant]

Ahh.. this -10dB line input pad isn’t documented in the manual.

Further testing confirms +10dB of channel gain is required for analog mixer 0 VU = Qu 0 VU (got a more accurate figure ensuring analog mixer was set to unity gain and then reading recorded values instead of eyeballing the Qu meters).

For recording analog mixer’s balanced +4dBU direct outs into the Qu, which is the better option:

1) Signal into Qu TRS Line inputs with +10db Qu preamp gain applied to negate the pad and line everything up
2) Signal into Qu XLR Mic inputs to avoid the 10db pad

Is the pad and extra makeup gain really that big of a deal in a studio recording context? Can the Qu Mic inputs handle a balanced line signal.. or could there be some sort of impedance problem? The analog mixer says the channel direct outs are “100 ohm Impedance-Balanced”.

I’m thinking option 1 is the way to go.
