M DAC Query

Hi.The Audiolab M dac with its own power supply. The power supply is a seperate item, when connect to main electric the power light comes on. When connected via the din plug to the M dac itself should the M dac light up immediately when turned on, or does the power supply need time to warm up. Hope some one can assist .thank you.

Can't imagine the psu needs any time.
Have you pressed the on/off button? Perhaps for a second or more.

Thanks for reply. Just arrived yesterday, wont power to M dac sending it back.

You could try a factory reset, it might just work even if the mdac doesn't look like it's on.
