Specifications
Analog Inputs:
The analog signal can be amplified by 0-12dB utilizing the front panel screw adjust trim pots. Full-
scale signal with 0dB gain is 24dBu, (full-scale signal with 12dB gain is 12dBu).
Input impedance over 0-100 kHz: greater than 20k ohm (pin 2 to pin 3).
Noise Floor at 44.1-48KHz sampling:
-130dB ±1dB from full scale A weighted
-126dB ±0.5dB from full scale unweighted
Noise Floor at 96KHz sampling:
-127dB ±1dB from full scale A weighted
-123dB ±1dB from full scale unweighted.
Notes:
1. Measuring noise floor with unconnected (opened) inputs may yield erroneous results.
Unconnected high impedance inputs may pick up unwanted signals.
2. Care must be exercised when measuring the noise floor. The signal applied to the converter
must be lower then the noise floor. Ordinary relays and switches may leak too much signal, and it
may be necessary to move a test tone signal to frequency above Nyquist (approx. 30KHz).
Output Bits: 16 to 24 bits, user selectable.
Total Harmonic Distortion and Noise:
(Specified for 22-24 Bits output, balanced inputs)
0.00005% for signals lower than -40dBF
0.0004% for signals lower than -20dBF
0.0008% for signals lower than -6dBF
0.0012% for full scale signals
Channel Separation:
Greater than 120dB (0-20KHz)
