Frequency response

Angle
Distance

Frequency response: from the manual, p. 23. "Specified Curves", CK 61-ULS on the C 480 B; relative dB. A thin dashed tolerance band is drawn around the nominal curve. Distance and field not stated.

Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.

Polar pattern

Polar pattern: from the manual, p. 23. "Polar Diagrams", CK 61-ULS; 125 Hz to 1 kHz on the left half, 2 to 16 kHz on the right; 0° at the bottom, rings every 5 dB, centre about -30 dB. Measuring conditions not stated. Approximate reading error up to about 1.5 dB.
