Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
This is a metal ceiling-embedded speaker with an integrated speaker unit, front net, and mounting hardware.
Designed with emphasis on sound quality, it is suitable for BGM applications in stores and other locations.
The spring clamp method allows you to easily mount the speaker to the ceiling.
Input changes can be easily made by replacing the transformer tap. It also supports low impedance (8Ω).
The speaker terminal block is a push-in type, making connections easy and compatible with feed wiring.
