Here some preliminary results on TSR inputs, phantom off, 96 kHz sampling, 24
bits, latest firmware, signal generator with 50 ohm output
max input before the red LEDs light on (1 kHz sinusoidal):
Level set to MAX with the buttons on the top of the unit:
L 850 mVpp
M 300 mVpp
H 110 mVpp
Level set to MIN:
L 3.3 Vpp
Level set to MAX, plus +27 boost:
L 39 mVpp
M 13 mVpp
H 4 mVpp
Low-end frequency response:
given 0 dB at 50 Hz
-1.0 dB at 20 Hz
-2.5 dB at 10 Hz
-3.0 dB at 8 Hz
-6.0 dB at 5 Hz
-8.0 dB at 4 Hz
-11.0 dB at 3 Hz
High-end frequency response:
flat up to 45 kHz, aliasing-free up to 42.5 kHz (aliased components - if any -
lower than -70 dB)
