Hoyt Electrical Instrument Works 17&3 VU 音量表 (VU表)

"The performance of the Hoyt VU meter is based on the requirements of BS-6840: Part 17:1991, IEC 268-17 1990. The dynamic characteristics quoted, which requires the response time to 99% of reference deflection (0VU) to be 0.3 seconds ±30ms, 0-100% with an over swing of at least 1.0% but not more than 1.5% are not fully met. The over swing, because damping is allowed to spread within normal design restraints, can vary to meet your specifications.","SCALE: (Scale \"B\" 0-100% Top Arc, -20 to +3 Bottom Arc)","SCALE COLOR: (White)","DIALS: (White on Black, Color, Special)","MOUNTING OPTIONS: (N\/A)","POINTERS: (Airplane, Lance, Spade)","POINTER COLOR: (Red, White)","ILLUMINATION: (12V or 24V Electroluminscent, 12V or 24V LED, 12V or 24V Bulb and Socket)"
