Input sensitivity M030 w/ 7040a

Input sensitivity M030 w/ 7040a

Hello,

I've just received a 7040a subwoofer to go with my M030. I am currently trying it, it's great !

I just have a doubt about the input sensitivity :

The only setting I can have between the two is M030 at 0dB and 7040a at 0dB as well, right ? Or am I missing something ?

I've always set up M030's sensitivity to -20dB, so I need to adjust/change a lot of things if I have to set it to 0dB.

Thanks !

Hi,

These two models have same maximum sensitivity, it is just written slightly different on the amplifiers.

0 dB equals -6 dBu
-10 dB equals +4 dBu
-20 dB equals +14 dBu (subwoofer adjustment doesn't go this low)

These are the numbers when looking at raw signal level, naturally room acoustics will change things a bit, usually subwoofer level needs to be set slightly lower than mains.
