Thank you for viewing. SONY ECM-260F condenser microphone and accessories set. Allows for high-quality audio recording. - Model: ECM-260F - Brand: SONY - Accessories: Microphone, microphone holder, cable, instruction manual - Color: Silver I bought this a long time ago when I purchased an 8mm camera and sound projector. However, I don't remember ever using it. It is in very clean and good condition. However, the instruction manual has yellowed due to aging of the paper. Also, I have not confirmed the operation of the product before listing it. Please purchase only if you are satisfied with the condition. ※ Please forgive any oversights. -- Reference -- Battery: 1 x AA battery External dimensions: Φ38mm x 179.5mm Weight: Approximately 125g (including battery) Frequency response: 50～14,000Hz Sensitivity: -70dB Maximum sound pressure level: 126dB
