XLogic Multichannel Compressor Owner’s Manual
Appendix C – Performance Specification
Conditions
Source impedance 50Ω unless otherwise stated.
All measurements are RMS and are made using a 22Hz to 22kHz filter unless otherwise stated.
Noise
Input terminated with 50Ω. Compressor switched in and set for 0dB gain.
Noise | < 99dBu |
Headroom
Headroom is defined at the output level at which THD exceeds 1%.
Headroom | > +26dBu output level, 20Hz to 20kHz at 0dB gain |
Dynamic Range | > 125dB |
Frequency Response
Measured reference level at 1kHz. Any gain setting. Source impedance 50Ω.
20Hz to 20kHz | ±0.05dB |
10Hz to 96kHz | |
10Hz to 200kHz |
Common Mode Rejection Ratio (CMRR)
Input level +20dBu, ground referenced.
20Hz to 10kHz | > 50dB |
THD + Noise
Gain +0dB, input level +4dBu. Master Fader switched in. Compressor switched out.
10Hz to 20kHz (80kHz filter) < 0.006%, typically 0.003%
Gain +0dB, input level +20dBu. Master Fader switched in. Compressor switched out.
10Hz to 20kHz (80kHz filter) < 0.01%, typically <0.006%
THD with the compressor switched in is dependent on attack and release times and signal content.
Crosstalk
Channel to channel crosstalk, measured with one input terminated with 50Ω. All channels at 0dB gain. Apply +20dBu test tone to any channel input except the one under test. Crosstalk is the ratio of level at the output of the test channel and the output of the channel to which the signal is applied.
Crosstalk @ 50Hz | < |
Crosstalk @ 1kHz | < |
Impedance
Input Impedance | > 10kΩ |
Output Impedance | < 40Ω |
