A.2.4 Instrument Input Performance

Un-balanced signal applied to Instrument Input and measured at Output. Pad switched out and Input Gain control set to +12dB (minimum).

Gain	Continously variable from +12dB to +75dB
	Independently switchable 18dB Pad available
Input Impedance	1MΩ
Output Headroom	> +26dBu at onset of clipping
THD + Noise	< 0.03% at 1kHz
(-18dBu applied, +28dB gain)	< 0.05% at 10kHz
Frequency Response	+0.05dB/-0.1dB from 20Hz to 20kHz
	–3dB at 150kHz
Equivalent Input Noise	< –82dB at +12dB (minimum) gain
(Input terminated with 150Ω)	< –88dB at +28dB gain (mid’ position)
