Microphone Input
Microphone Input: Input impedance 300 Ohms or 1200 Ohms, gain +80dB to +20dB in 5dB steps.Input is transformer balanced and earth free
Line Input
Line Input: Input impedance 10,000 Ohms bridging, gain +20dB to -10dB in 5dB steps.Input is transformer balanced and earth free
Output:
Output: Maximum output is >+26dBu into 600 Ohms. Output impedance is 75 Ohms +/-5% @ 1kHz, balanced and earth-free.An unbalanced output 8dB below the level of the balanced output is also provided.
Frequency Response
Frequency Response: +/-0.5dB from 20Hz to 20kHz, -3dB at 7Hz and 35kHz
Noise
Noise: Output noise better than -42dBm from Zin 1200 Ohms and -80dB input, giving an equivalent noise of -125dBm referred to 600 Ohms input impedance fed from 100 OhmsOutput noise better than 80dBm at all line input levels 22Hz to 22kHz bandwidth
