Mini-DA42
AES42/AES3 converter with analog outputs
The Mini-DA42 powers digital microphones and has both digital andanalog outputs. All inputs and outputs are available through a Sub-D
breakout cable.
On the Mini-DA42 there are a green Power LED and a red“Unlocked” Error LED which turns off as soon as the device
successfully locks to the connected digital microphone.
Inputs:-AES42, Mode 1 (XLR-3F, 100 Ohms, black label)-power: DC 12 - 18V / 200 - 500 mA, available throughincluded AC adapter for 100 - 240 V, 50 / 60 Hz withHIROSE plug. Operation is also possible with other AC
adapter models or batteries / rechargeable batteries.

Mini-DA42:
AES42 converter with analog outputs

Outputs (available through included Sub-D breakout cable):-

AES3 (XLR-3M, 100 Ohms, blue label)-

2 * analog (XLR3-M, yellow and red label), balanced,referring to ground, maximum cable length: 300 m

Technical specifications:-sampling rate: max. 192 kHz-

dynamic range: 112 dB (A, RMS), >98 dB(CCIR, q-peak)-frequency range: 2 Hz .. 20 kHz (-1 dB)-

THD + N: < -95 dB @ 1 kHz-output level: max 14.5 dBU @ 0 dBFS.
In normal operation, the analog outputs will require someamplification, since digital input signal levels are typicallyrather far below full scale. When using the +30dB levelboost of the SCHOEPS SuperCMIT, normal line inputs aresufficient.

-power consumption (including SuperCMIT): 200 mA-dimensions in mm: 84 * 84 * 34; weight: 173 g

Breakout cable for Mini-DA42:
input: 1 * AES42,output: 1 * AES3 out, 2 * analog

PSD 2U
Digital Phantom Powering (AES42/AES3 converter)
The PSD 2U provides the digital phantom power (DPP, 10V) for adigital microphone like the SuperCMIT. It can be connected to anormal digital AES3 input (XLR/RCA).
Inputs:-AES42, Mode 1 (XLR-3F)-power: DC 12 - 18V / 500 mA, available through included
AC adapter for 100 - 240 V, 50 / 60 Hz with HIROSE plug

Connecting the digital microphone SCHOEPS SuperCMITThe SuperCMIT is a digital microphone that conforms to the AES42 standard, Mode 1. You
connect it to an interface offering Digital Phantom Power (DPP, 10 Volts).
The SuperCMIT runs on its own internal clock. If you run more than one SuperCMIT or if youprefer to use an external clock, your digital input must use sampling rate converters (SRC).
Furthermore, in a normal workflow, the digital input should also offer sufficient gain (20 - 30dB) for recording and monitoring in real time.
The following chart lists some currently available devices and shows their properties withregard to the above requirements.

built-in DPP and SRC (= it has an AES42/Mode1 interface)sufficient gain (+50 dB) in the digital input-peak limiter and low-cut filter are available-Digital input gain is controlled by rotating the “Select Encoder” from the input's
Input Settings Screen. You can see this in the PFL-mode.

no DPP, need a powering device like the SCHOEPS PSD 2U or Mini-DA42
no SRC in the digital input, the digital microphone has to be the master clock!

-no digital gain available, +30 dB gain option in the SuperCMIT should be used

RME DMC-842
8 × AES42 input (=4 two-channel inputs) with SRC, DPP and gain-

8 × analog output (XLR)
4 × AES3 output , 2 × ADAT output-For operation with SCHOEPS digital microphones, the control pulses (CP) and syncpulses (SP) have to be turned off in the setup menu of the DMC-842 or the signal-tonoise ratio may decrease. The easiest way is to activate 'Auto CP/SP' and 'Auto SRC'in the setup of the remote software.
