Note
1. Operating condition
• Power source : 220-240V 50 Hz / 220V 60 Hz
• Cooling : Indoor temperature (27°C DB, 19°C WB),
Outdoor temperature (35°C DB, 24°C WB)
• Heating : Indoor temperature (20°C DB, 15°C WB),
Outdoor temperature (7°C DB, 6°C WB)
• External static pressure is according to “Standard mode” value. Refer to the specifications.
2. Data is valid at diffuse field condition.
3. Data is valid at nominal operating condition
4. Sound level can be increased in static pressure mode or used air guide.
5. Sound level will vary depending on a range of factors such as the construction (acoustic absorption coefficient).
6. Reference acoustic intensity 0dB = 10E-6μW/m

7. Sound power level is measured on the rated condition in the reverberation rooms by ISO 3741 standard.
Therefore, these values can be increased owing to ambient conditions during operation.
