Ultra Sub Voltage

[Dizzydj1210]

Good evening forum users

I wonder if anybody can answer this.......

Im going to be running 2x ultra into a behringer nx4-6000, one of the ultra will have a sub connected to a behringer nx1000

The input on both amps is 775ma, so was going to set line out at 800ma, but what is the subwoofer out on the ultra, and can this be changed like the line out?

Thank you in advance

Kind regards
Steve

The sub output voltage at 0 dBFS and volume control at 100% is not given in the official specifications.

However, according to measurements taken here ...

WiiM Ultra

Is it? I'm not sure how. Happy to try. Given that there will be different amps and speakers being connected, how does the ultra manage the relative volume anyway?

... it's probably 1.0 V. The level can be adjusted by +/-15 dB from within the WiiM Home App, so this number isn't really fix.

I don't see any figures regarding input sensitivity or gain in the NX1000 quick start guide. Does it come with a full manual including these characteristics?

Good morning

On page 31 it states 0.775v input

Probably leave it at 0 on the app, and see how it performs

Thanks for the reply.

Hi Dizzydj1210,

The subwoofer voltage of WiiM Amp and WiiM Ultra is 2Vrms.

Hello

Can this be reduced? as the input of the amp I cam going to use is 0.775? Or would I just reduce this via the slider on the app?

Kind regards
Steve

Hi Dizzydj1210,

Based on the 0.775V input sensitivity of your subwoofer, try setting the subwoofer output level of your WiiM Amp to -9dB and see if the subwoofer sounds optimal.

Hi Dizzydj1210,

The subwoofer voltage of WiiM Amp and WiiM Ultra is 2Vrms.

Might be a good idea to include this value in the official specs?
