The RME 12Mic-D features twelve microphone and line level inputs with digital, no-compromise, studio-quality conversion; remote controllable gains; integrated MADI and Dante connectivity; plus a multitude of additional functionality, designed for use in high-end studio recording, live audio, and location sound and music recording. The PAD-free microphone input stages have a 75 dB gain range and accept signals of up to +18 dBu. On the converter side, the 12Mic shines with an outstanding signal-to-noise ratio on all channels. All twelve front-facing XLR connections accept microphone and line level signals, whilst the first four connections also accept TRS connectors, with switchable high impedance (Hi-Z) for instruments.In addition to Dante, the 12Mic-D has two separate MADI ports- with coaxial built into the device as standard, and optical MADI available via an optional SFP module – along with three ADAT outputs and a line level headphone output for monitoring all incoming digital and analog signals. With the help of a routing matrix, any of the 12Mic-Ds 204 input channels can be individually routed to any of the 218 output channels.When connected to a Dante network, a combination of both analog and digital channels (such as connected MADI devices) can be transmitted to the network if required. In return, the 12Mic-D can receive up to 64 audio channels from the Dante network, which in turn can be forwarded to the headphones, ADAT, and two MADI connections as required.Specifications:Inputs:XLR In 1-12: Input: XLR, electronically balanced Input impedance: 3.4 kOhm Gain range: 75 dB, 1 dB steps Resolution AD: 24 bit Frequency response @ 44.1 kHz, -0.1 dB: 8 Hz 20.8 kHz Frequency response @ 96 kHz, -0.5 dB: 4 Hz 29.2 Frequency response @ 192 kHz, -1 dB: 3 Hz 43.7 THD @ 30 dB gain: < -110 dB, < 0.00032 % THD+N @ 30 dB gain: < -104 dB, < 0.00063 % Channel separation: > 110 dB Signal to Noise ratio (SNR): > 117 dB RMS unweighted, > 120 dB(A) Equivalent Input Noise (EIN), 30 dB Gain: 123 dB RMS unweighted, 125.5 dB(A) @ 150 Ohm Maximum input level, Gain 0 dB: +18 dBu Maximum input level, Gain 75 dB: -57 dBuTRS In 1-4:As above, but: Signal to Noise ratio (SNR): 115 dB RMS unweighted, 118 dBA TRS jack, balanced Gain range: 42 dB, 1 dB steps Maximum input level, Gain 8 dB: +20 dBu Maximum input level, Gain 50 dB: -22 dBu Switchable high impedance (unbalanced TS): 1 MOhmDANTE: 2 x RJ45 for Dante network connectivity (up to 64 channels)MADI: Coaxial via BNC, 75 Ohm, according to AES10-1991 Optical via optional SFP module 62.5/125 and 50/125 compatible Accepts 56 channel and 64 channel mode, plus 96k Frame Single Speed: up to 64 channels 24 bit 48 kHz Double Speed: up to 32 channels 24 bit 96 kHz Quad Speed: up to 16 channels 24 bit 192 kHzWord Clock: 75 ohm Word Clock BNC connectivity Support 44.1kHz – 192kHz Support full or single speed operation Intelligent Clock Control switches clock source seamlesslyADAT: 3 x TOSLINK Quad Speed (S/MUX4): 1 x 2 channels 24 bit 192 kHzOutputs:Phones 1/2: Resolution: 24 Bit Noise (DR): 115 dB RMS unweighted, 118 dBA Frequency response @ 44.1 kHz, -0.5 dB: 9 Hz 22 kHz Frequency response @ 96 kHz, -0.5 dB: 9 Hz 45 kHz Frequency response @ 192 kHz, -1 dB: 8 Hz – 75 kHz THD+N: < -100 dB, < 0.001 % Channel separation: > 110 dB Output: 6.3 mm TRS stereo (unbalanced) or mono (balanced) jack Maximum output level at 0 dBFS: +13 dBu (unbalanced), +19 dBu (balanced)DANTE: 2 x RJ45 for Dante network connectivity (up to 64 channels)MADI: Coaxial via BNC, 75 Ohm, according to AES10-1991 Optical via optional SFP module 62.5/125 and 50/125 compatible Accepts 56 channel and 64 channel mode, plus 96k Frame Single Speed: up to 64 channels 24 bit 48 kHz Double Speed: up to 32 channels 24 bit 96 kHz Quad Speed: up to 16 channels 24 bit 192 kHzWord Clock: 75 ohm Word Clock BNC connectivity Support 44.1kHz – 192kHz Support full or single speed operation Intelligent Clock Control switches clock source seamlesslyGeneral:2x RJ45 for Dante network connectivity: Single Speed: up to 64 channels 24 bit 48 kHz Double Speed: up to 32 channels 24 bit 96 kHz Quad Speed: up to 16 channels 24 bit 192 kHz MADI input redundancy (requires optional SFP module) Internal routing of up to 268×282 channels 19 enclosure 1 unit height 1,54 full color display with control knob and four buttons for convenient, direct access to all features Remote control via HTTP, JSON, IEEE 1722.1 AVDECC, MIDI over MADI internal PSU, optional 12V DC redundant power supply USB 2.0 (for remote control and firmware updates) DC-coupled outputsHardware Specifications: Dimensions: 440 x 44 x 243 mm (17.3 x 1.7 x 9.6 inches) Weight: 2.8 kg (6.2 lbs) Package: 560 x 315 x 115 mm (22.1 x 12.4 x 4.5 inches) Conformity: CE, FCC, WEEE, RoHS Power supply: internal 30 W 100-240 V AC, external 12 V 2.5 A DC (optional) Power consumption: typ. 20 W, standby 0.5W
