Appendix C – Performance Specification

Conditions:

Source impedance 150Ω unless otherwise stated.

All measurements are RMS and are made using a 22Hz to 22kHz filter unless otherwise stated.

General

Gain:	Continuously variable from +18dB to +72dB with switchable 20dB pad
Input Impedance:	>1200Ω switchable to 8200Ω

Noise

Input terminated with 150Ω

Equivalent input noise:
Gain	EIN
70dB	–129dBu
50dB	–129dBu
40dB	–128dBu
30dB	–127.5dBu
18dB	–120dBu

Frequency Response

Measured reference level at 1kHz. Source impedance 50Ω.

	Minimum Gain	Maximum Gain
20Hz to 20kHz	±0.1dB	±0.1dB
10Hz to 96kHz	±0.2dB	+0.2/–0.75dB
10Hz to 200kHz	+0.2/–1dB	+0.2/–6dB

Common Mode Rejection Ratio (CMRR)

At minimum gain (+18dB), input level +6dBu, ground referenced:

Frequency	CMRR (dB)
20Hz to 1kHz	> 75dB
10kHz	> 60dB

At maximum gain (+72dB), input level –45dBu, ground referenced:

Frequency	CMRR (dB)
20Hz to 1kHz	> 85dB
10kHz	> 75dB
