 Model****1C uses a logic circuit to generate Pseudo Random Noise, it is the newest and the most advanced design to generate audio white noise. It has a much flatter frequency response than using a diode. Model****1C has: (1)White noise source. (2)Weighting filters.(3)Built-in power amplifier. (4) TRUE RMS voltage meter circuit. It can generate five different kinds of noise spectrum, including White Noise, Pink Noise, and three kinds of Weighted Noise, that conform to the following nations standards:(1) JIS C***1, IEEE **9, CNS ***5 (2) EIA **6B(3) DIN ****3 
 

1. White Noise:

*3dB Bandwidth: *0Hz～**0kHz,

Roll off:**4dB / Oct.  Flatness: ±1dB

2. Pink Noise:

*3dB Bandwidth: *0Hz～*0 kHz

Roll-off: **4dB / Oct. Crest factor: 4 ( IEEE **9 )

Amplifier:

1.**0W output is defined at an unclipped maximum output of sine wave.

2.Frequency response : *0 Hz~*0 kHz ±0.2dB; *0 kHz~**0kHz ±1dB

3. Output: With permanent short circuit protection.

Load Impedance: ≧ 3.2 Ω.
