Input/Output Characteristics
DME24N ANALOG INPUT CHARACTERISTICS
• 0dBu = 0.775 Vrms
• All AD converters (CH1-8) are 24-bit linear, 128 times oversampling.
• +48V DC (phantom power) is supplied to CH INPUT (1-8) connectors via each individual
controlled switch.
DME64N ANALOG OUTPUT CHARACTERISTICS
• 0dBu = 0.775 Vrms
• Stereo Phone Jack = unbalanced (Tip = LEFT, Ring = RIGHT, Sleeve = GND)

Frequency Response 20Hz – 20kHz, reference to the nominal output level
@1kHz
Frequency Response fs = 96kHz@20Hz – 40kHz, reference to the nominal
output level @1kHz
Gain Error @1kHz
Total Harmonic Distortion fs = 48kHz
Total Harmonic Distortion fs=96kHz
Hum & Noise EIN = Equivalent Input Noise
• Hum & Noise are measured with a 6dB/octave filter @12.7kHz; equivalent to a 20kHz filter
with infinite dB/octave attenuation.
Dynamic Range
• Dynamic range are measured with a 6dB/octave filter @12.7kHz; equivalent to a 20kHz filter
with infinite dB/octave attenuation.
