We always quote 'real world' performance figures (measured to the AES17 standard). Some companies choose to quote chipset performance, which is misleading, and here's why.
Mic Input Response
- Gain range: 0dB to 60dB in 10dB steps
- Input Impedance, variable: 600?, 1k4?, 2k4?, 6k8?
- EIN (equivalent input noise): -126dB measured at 60dB of gain with 150 Ohm terminating impedance and 22Hz/22kHz bandpass filter
- Noise at main output with gain at unity (0dB): -97dBu measured with a 22Hz/22kHz bandpass filter
- Signal to noise ratio relative to max headroom (9dBu): 106dB
- THD at medium gain (30dB): 0.0008% measured with a 1kHz -20dBu input signal and with a 22Hz/22kHz bandpass filter
- Frequency response at minimum gain (0dB): -0.5dB down at 10Hz and –3dB down at 110kHz
- Frequency response at maximum gain (60dB): –3dB down at 16Hz and –3dB down 85kHz
- CMRR: 91.8dB (Channel 1, 1kHz, maxiumum gain)
- Crosstalk Channel to Channel: with 10dB@1kHz input to chA, chB output =102dBrA. With 10dB@10kHz input to chA, chB output = 84dBrA
Line Input Response
- Gain range: -20dB to +10dB in 10dB steps
- Input Impedance: 10k? from 10Hz to 200kHz
- Noise at main output with gain at unity (0dB): -96dBu measured with a 22Hz/22kHz bandpass filter
- Signal to noise ratio relative to max headroom (24dBu): 120dB
- Signal to noise ratio relative to 0dBFS(+22dBu): 118dB
- THD at unity gain (0dB): 0.001% measured with a 0dBu input signal and with a 22Hz/22kHz bandpass filter
- Frequency Response at unity gain (0dB): 0.3dB down at 10Hz and –3dB down at 122kHz
Instrument Input Response
- Gain range: 10dB to 40dB continuously variable
- Input Impedance: 1M? or 300k?
- Noise at minimum gain (+10dB): -90dBu measured with a 22Hz/22kHz bandpass filter
- Noise at maximum gain (+40dB): -62dBu measured with a 22Hz/22kHz bandpass filter
- THD at minimum gain (+10dB): 0.002% measured with a 10dBu input signal and with a 22Hz/22kHz bandpass filter
- Frequency Response at 10dB gain with -10dB input: 10Hz-200kHz +/- 0.6dB
- Frequency Response at 40dB gain with -40dB input: -2.5dB down at 10Hz and 0dB at 200kHz
High Pass Filter
- Roll off: 18dB per octave 3 pole filter
- Fixed Frequency 75Hz measured at the 3dB down point
