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

+0.2/-0.5dB

10Hz to 200kHz

+0.2/-2dB

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

< –105dB

Crosstalk @ 1kHz

< –90dB

Impedance

Input Impedance

> 10kΩ

Output Impedance

< 40Ω
