2.1 Powering considerations
Even though the Nymphes is an analog synthesizer, it can be powered with a simple USB cable. Giving the unit
some extra mobility, you can just use a power bank and play anywhere (with a 20.000 mAh power bank you could
power and play the unit for up to 55 hours).
Most households nowadays have at least a dozen or so USB cables and power adapters available.
So, you’re thinking, “Can I use any USB power supply?”
Yes, but there are some things you need to take into consideration.
Not having a dedicated power adapter means that
depending on the USB power supply quality or your connection, could result in a dirty synth and noise oor.
You can easily avoid those situations by following these simple rules:
- When you turn the Nymphes on, there is a burst of noise occurring. This is normal but in order for this to happen,
make sure you have the level of your monitor/amp turned off.
- Power the Nymphes and all the devices connected to it, from the same mains power line. You should
specically avoid using different mains. For example a mains line for Nymphes and a different one for your
amp/monitor that have internal protection circuit. This can produce a constant noise generation from the output
of the synthesizer, which can only be eliminated by reseting the unit.
- When powering the Nymphes from a computer, if you use a DAW to work with the MIDI CC documentation, a
ground loop can be created, causing a noticeable hum. In that case, you should power the Nymphes from a
different power supply and not from the same computer that you’re running the DAW on.
You can do that with the use of a USB data/power splitter.
- Using a very long USB cable can also cause line noise. For cleaner sounding performance it is also better to
use a USB cable that has a ferrite bead installed.
- Make sure your USB power adapter is rated for at least 1A - Poor quality USB power adapters should be
avoided.
- Also have in mind - as mentioned before - when using a power bank, make sure it’s a good quality one.
You can also power a keyboard controller with the same power bank.
2.1.1 Bad power supply (or cable) side effects
- May not boot Nymphes
- Lots of noise, abnormal sound elements
- Wobbly oscillators
- Firmware update may not work
If you have any of the above effects, replace your adapter and/or cable asap.
You should also avoid leaving the synth on power when you are not going to use it for a long period of time
(and that should be a rule for every electrical/electronic device) for various reasons.
Most important reasons are:
- Expanded life circle
- Protection of the environment
