20 Hz - 22 kHz, +0.1, -0.5 dB, -1 dB at 50 kHz (relative to 1 kHz level with 150 ohm source)
Equivalent Input Noise:
-126 dBu (-128 dBV) maximum (150 ohm source, flat weighting, 22 - 22 kHz bandwidth, gain setting 36 dB or greater)
Output Clipping Level: +22 dBu min. with 100k ohm load; +20 dBu min. with 600 ohm load
Input Clipping Level:
+4 dBu minimum at the 0 or +18 dB gain setting
Dynamic Range:
122 dB minimum at the +18 dB gain setting
THD + Noise:
0.05% Maximum (from 60 Hz to 22 kHz @ +4 dBu output level, 22 Hz - 22 kHz filter bandwidth, +46 dB gain setting)
Common Mode Rejection Ratio:
100 dB minimum at 80 Hz; 60 dB minimum at 10 kHz
Input:
Transformer-balanced, 2000 ohm input impedance
Output:
