Dear Forum Members,
I have a Muse model 2 dac and I am not sure about a "switch' that is located near the power supply section. Photos are attached for reference - with red circle highlighting the particular item, which I think is a flip switch. As I am not familiar with electronics, I dare not attempt to proceed any further as I could not find any online info or schematic.
I hope that I could get some help here, and my question is:
1. is this a DPDT switch to select the appropriate mains voltage ?
2. Now its currently on the right hand side (as shown in picture ) and I believed its for 120VAC. So by switching it to the left hand side, it would switch to 220VAC ?
3. And should I replace the fuse too ?
I just received this DAC from USA and have not switched-on or operate this DAC. I plan to use it for 220/240vac voltage.
I have either the option to use a step down voltage transformer
or if I could flip the "switch" correctly, then I could safely connect the DAC directly to 220/240VAC - without damaging it.
The manual state that:
"A DPDT switch located on the power supply board selects the appropriate mains voltage (either 120 or 220-240 VAC 50 or 60 Hz). Protection from over voltage is provided by MOVs on each primary winding. Over current protection is accomplished by a fuse connected in series with the transformers primaries."
Looking forward to sort this out - thank you so much.

I'd say your supposition is correct - that switch changes the mains voltage.
If you want to be sure you got it set correctly, do you have a multimeter to check the resistance between mains live and neutral at the input socket? The 120V setting will show about 1/4 of the DC resistance compared to the 220V setting.

Hi,
Thank you for your reply info. Incidentally, I don't have a multi meter and had never used one before. Due to Cov19 lockdown - a bit of inconveniences.
And your comment on making sure that it's set correctly is valuable info - that I should be aware of, as there is no power switch on this DAC - on off button. Just need to be extra careful, before I attempt to connect/switch on this DAC to mains. I will look up more info online on how to measure the resistance part, etc., in your helpful comment.
If there is a simpler alternative way to do that for someone who is not familiar with electronic knowledge - I sincerely welcome your comments. My sincere apology for my lack of knowledge.
I am happy to know that the switch is for a change in the mains voltage, and if done correctly, I don't have to use a step down/up voltage transformer.
Thank you kindly....

I flip the DPDT switch to 220/240v and replaced the fuse with a new 250mA 250v Glass cartridge fuse Speed T - and now its running on 220V settings.
So far so good. Love the sound of this DAC.
Thank you so much to you and diyAudio - for the help and suggestions.
Cheers and keep safe...
