OPUS QUAD from japan VOLTAGE?

Congratulations on your new purchase!

You're right to be cautious about the voltage rating, as it's common for Japanese products to have a higher voltage range than what's listed on the box.

Based on your previous experience, it's likely that the Opus Quad also has a multi-voltage range, despite the 100V rating on the box. However, without confirmation from the manufacturer or a detailed technical specification, it's difficult to say for sure.

Here are a few things you can do to clarify the situation:

1. **Check the product manual or documentation**: If you receive the product manual or documentation from the seller, take a look at the electrical specifications or technical details section. This might give you a better idea of the voltage range.
2. **Contact Pioneer DJ or the seller**: Reach out to Pioneer DJ or the seller and ask them specifically about the voltage range of the Opus Quad. They might be able to provide more detailed information or confirm that it's indeed 100V-240V multi-voltage.
3. **Check for CE marking**: If the Opus Quad is intended for use in Europe, it should have a CE marking (a symbol of conformity with EU safety standards). This doesn't necessarily mean it's multi-voltage, but it's an indication that it's designed to meet certain safety standards.

If you're still unsure about the voltage range after checking these sources, it's always a good idea to use a transformer to ensure safe and proper operation of your equipment.

Remember that it's better to be safe than sorry when dealing with electrical equipment, especially when working with high-voltage devices like professional audio gear.

Keep me updated on your findings, and let me know if you have any further questions!
