8010A + 7040A Sub: Starting point sensitivity settings?

8010A + 7040A Sub: Starting point sensitivity settings?

Youngling Posts: 3 Join Date: 10/17/16 Recent Posts
8010A has input sensitivity 0 or -10dB (where higher dB = higher output)
7040 has input sensitivty +12dB to -6dB (where higher dB = lower output)
My source, Audinet ID14, has output levels up to +12dB

1. Why does lowering sensitivity on the 8010A lower output whereas on the 7040A it increases it?
2. What's a good starting position for this setup?
8010A 0dB, 7040A 0dB (goes too loud when cranking up the volume to max)?
or 8010A -10dB, 7040A +10dB?

Appreciate any input :)

So far using -10db for the monitors and +6dB for the sub.

Hi, good question!

Actually they are the same, just written slightly differently. The default input sensitivity of the monitors is also -6 dBu for 100 dB output at meter distance, just as the subwoofer's. By using the -10 dB switch, you can reduce this sensitivity to +4 dBu. It goes that way as it requires higher input signal to reach certain SPL. So, -10 dB switch on the monitors and +6 dB on the sub works really well. Our typical recommendation for the subwoofer level is -4 dBu if the speakers are set to default sensitivity.

Thanks, that clears it up! The manual wasn't clear about this.
