| External dimensions | 320X360X100mm |
| Weight | 4kg |
| The characteristic | 1、Adopting 7th order Chebyshev-type high pass and low pass adjustable active filters, it can carry out band pass, low pass, high pass, and limiting processing on audio signals with good frequency characteristics and easy to use, and can be widely used in electro-acoustic devices and audio equipment electro-acoustic performance testing and acoustic measurement research.
2、The cutoff frequency of the low-pass filter is 10 Hz – 3100 Hz in 10 HZ increments or decrements. 3、The cutoff frequency of the high pass filter is 500Hz-20KHz with a 500Hz increment or decrement. 4、There are two sets of analog holiday signal filters, of which set “I” is suitable for pink noise input and set “II” is suitable for white noise signal input. |
| Main technical parameters | 1、Frequency range: 20Hz – 20KHz.
2、Fluctuation within the passband of the filter: 0.5dB. 3、Loss at cutoff frequency: (-3dB)–(+3dB). 4、 First-octave wail at cutoff frequency: not less than 50dB. 5、Limiter: Capable of limiting the input signal by 2, 3, or 4 times the peak value. 6、Maximum input signal: 1Vrms (with level meter indication). 7、Input impedance: 500kΩ. 8、Output impedance: 600Ω. |
