Note: Dependent on microphone type |
- Audio Dynamic Range (System Gain @ +10): >120 dB, A-weighted, typical
- Total Harmonic Distortion (−12 dBFS input, System Gain @ +10): <0.1%
- System Audio Polarity: Positive pressure on microphone diaphragm produces positive voltage on pin 2 (with respect to pin 3 of XLR output) and the tip of the 6.35 mm (1/4-inch) output.
- Operating Temperature Range: -18°C (0°F) to 50°C (122°F)
Note: Battery characteristics may limit this range.
- Storage Temperature Range: -29°C (-20°F) to 74°C (165°F)
Note: Battery characteristics may limit this range.
