Schoeps DigitalShotgun microphone SuperCMIT
AES42 Interface
The SuperCMIT is a digital microphone. Its output signal format is AES42, Mode 1. This means that it runs on its own clock (48 kHz) and must be driven by an AES42 input with a sample rate converter (SRC). With the optional PSD 2U powering adapter, it can also be used with a conventional AES3 input having built-in SRC.
The AES42 standard defines the interface for digital microphones. In the simplest case AES42 requires only an AES-3 interface plus 10-Volt digital phantom powering (DPP). AES42 interfaces are available in some equipment such as the RME DMC-842 8-channel interface and the Sound Devices 788T portable 8-channel recorder.

Options for connecting the SuperCMIT
You can download the list below.
If you want to use the SuperCMIT properly in a normal workflow, you have to care for:
- digital phantom power (DPP, 10 Volts)
- a digital input with sample rate converter (SRC)
- sufficient gain of the digital input for instantly making recordings and for monitoring, peak limiter
The following list comprises some currently available devices and depicts their properties with regard to the above-mentioned
demands.

- 1. SCHOEPS PSD 2U
- powering box for 10 Volt digital phantom powering (DPP) with XLR and RCA outputs
- input: AES42, outputs: AES3 (AES/EBU) and AES-id (Cinch)
- an AC adapter for 100 - 240 V, 50 / 60 Hz with HIROSE plug is included
- this device needs to be connected to an AES3 input with sample rate converter (SRC)
- 2. SCHOEPS Mini-DA42
- miniature D/A converter with 10 Volt digital phantom powering (DPP)
- input: AES42
- outputs: AES3 (XLR-3M), 2 × analog (balanced, XLR-3M)
- a Sub-D breakout cable is included
- an AC adapter for 100 - 240 V, 50 / 60 Hz with HIROSE plug is included
- 3. SoundDevices
a) 788T- with built-in DPP and SRC (= it has an AES42/mode 1 interface)
- with sufficient gain (+50 dB) in the digital input
- peak limiter and low-cut available
- b) other products from SoundDevices
- no DPP, need a powering device like the SCHOEPS PSD 2U
- 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
- 4. ZAXCOM DEVA
- has no DPP, needs a powering device like the SCHOEPS PSD 2U
- all newer Zaxcom devices have SRC in the digital inputs
- offers digital input gain:MENU > Input configure > "Analog input toggle" > choose the "digital input" > digital fader max. 30 dB gain
- a compressor / limiter can be inserted in the digital inputs
- 5. AATON Cantar
- with SRC in the digital input
- no gain adjustment in the digital inputs
- until now: no DPP
- 6. AETA 4MinX
- 2 × AES42 inputs with SRC
- 7. TASCAM HS-P82
- 8 AES/EBU inputs with SRC
- has no DPP, needs a powering device like the SCHOEPS PSD 2U
- no gain adjustment in the digital inputs available, +30 dB gain option in the SuperCMIT should be used
- peak limiter and low-cut available
- 8. RME DMC-842
- 8 × AES42 input with SRC, DPP and gain
- 8 × analog output (XLR)
- 4 × AES3 output (AES/EBU), 2 × ADAT output
- For operation with SCHOEPS digital microphones, the control pulses (CP) and sync pulses (SP) have to be turned off in the setup menu of the DMC-842 - otherwise the signal-to-noise ratio may decrease. The easiest way is to activate 'Auto CP/SP' and 'Auto SRC' in the setup of the remote software.
- 9. Lake People DAC C462
- 1 × AES42 input
- 1 × AES3 output (AES/EBU)
- 2 × analog output
- gain adjustable from 0 dB to 48 dB in steps of 6 dB
- headphone monitoring options: L/L, L/R, R/R
- 10. Neumann
a) Neumann Connection Kit- powering box for 10 Volt digital phantom powering (DPP) with XLR output
- input: AES42, output: AES3 (AES/EBU)
- this device needs to be connected to an AES3 input with sample rate converter (SRC)
- b) Neumann DMI-2
- 2 × AES42 input
- 2 × AES3 output (AES/EBU)
- this device needs to be connected to an AES3 input with sample rate converter (SRC)
- c) Neumann DMI-8
- no mode-1 support
- does neither work with the SCHOEPS SuperCMIT nor with the CMD 2!
- 11.Zaxcom TRX942
- digital recording transceiver for boom (the launch has been announced for November 2010)
- custom-made AES42 input for the SuperCMIT
- transmission of one output channel only (can be selected)
- 12.Audioroot eSMART 42-DH
- battery-powered box for 10 Volt digital phantom powering (DPP)
- input: AES42, output: AES 3
- 2 additional HRS power outputs for mixer / recorder supply
- can also be operated from an external power supply
