I have tested DC offset from the Hypex ncore amplifiers terminal with the Ultra as source.

Hypex ncore power amps do not have any dc protection on the rca input. This is unusual.

The ultra do not have blocking capacitors on the rca output and could potentially send DC to the amplifier.

Onlyoneme measured the DC offset in Ultra from the rca output to be 0.25 mV in idle, and 1.2 mV for full scale 1 kHz sine.

My setup was ultra - rca cables - Hypex ncore 125 . The ultra set to pause after playing some music one hour . Volume put to 30.

I followed this advice:

The DC result measuring with a volt meter at the amplifiers left loudspeaker terminal was 2 mV, or 0.002 V.
Very low , so I guess there is no worries about to much DC.

What do the experts say about this result ?
