Technical Specifications
D612 Digital & Analog console
Audio Inputs
4 balanced MIC inputs (XLR)
2 balanced stereo Line inputs (DIN 5)
3 unbalanced stereo Line inputs (RCA)
1 Digital stereo Line input (USB)
Inputs Level & Impedance
Balanced MIC= -10 dBu/-75 dBu; 150 / 250 Ohms
Balanced LINE = -20 dBu / +26 dBu; 600~ 10Kohms
Unbalanced LINE = -15 dBu / +12 dBu; 600~ 10Kohms
Phantom Power
Two MIC inputs have 48 V phantom power supply, switchable ON / OFF // Complies with DIN 45596 standard
Analog Outputs
2 bus stereo outputs; PGM (6,35mm, TRS plug) & REC (RCA connector)
Both at + 4 dBm = 0 VU
PGM balanced: Max Level +26dBu (10K), +20dBm (600 ohms)
REC unbalanced, Max level 20 dBu
External Hybrid: unbalanced Mic-Minus out at + 4 dBu
Digital USB Input / Output
USB digital In/Out; Input to channel 5; Output to PGM or REC
It uses the K15 Overload recommendation for broadcating;
Then, 0 VU is at -15 dB Full Scale level
