>>In any case, the noise values ​​do not seem to differ significantly from other consoles.
Or do you see it differently?

I feel that it won’t change much. However, when adjusting the TF1, etc., which I used as an example, I feel that it is better to go beyond the gain of the analog preamplifier by one step and adjust the digital gain to lower the floor noise relative to the signal.

I find this setting method cumbersome.

Maybe I’m misunderstanding you, but I would say it’s not possible to implement it in SQ, because the preamp gain is controlled completely differently on the hardware side – also like KeithJ already answered.

thank you.
Steps so far Consciously choose a YAMAHA mixer I was curious because I was using it.
I was confident that I didn’t have to worry about it.

thank you
This is exactly what I want to say.

I don’t see any particular benefit to this mechanism.

However, when using a YAMAHA mixer with this mechanism, for example, if the analog gain is 35 dB and the volume is just right, I adjust the analog gain from 36 dB to 38 bB and use the digital gain to lower the volume. .

This is because the S/N ratio is better.

I would like to know if these adjustments are necessary for Allen and Heath’s SQ series.

Hi tobi
Thank you for your reply

The Yamaha TF1 exhibits notable symptoms, but this is a characteristic of the head amp configuration in Yamaha’s digital mixers in general, which control Gain using a combination of two PAD values, two AMP values, and five ATT values.

The PAD values are 0 and -24, the AMP values are 14 and 38, and the ATT values are 24, 18, 12, 6, 0. These combinations are used to control the Gain.

Although the mixer allows for adjustments in 1dB increments, the noise floor increases with each 1dB gain increase. Every 6dB, the combination of PAD, AMP, and ATT changes internally, causing the noise floor to reset.

I’m curious whether this variation in the S/N ratio could also occur in the SQ series.

thank you.
Is it okay to recognize that the gain can be controlled linearly at 1db and the S/N ratio does not change from the minimum to the maximum?
