 Euphonix SH612 Studio Hub User Guide Getting Started

Synchronization signals are distributed via four AES Sync (AES/EBU), Word Clock, 
video, or MTC outputs to System 5 or R-1 components. The SH612 can generate or 
lock to Time code, or convert between different formats. All standard time code rates 
are supported: 
• Film: 24 fps
• PAL/SECAM: 25 fps
• Color NTSC: 29.97 (drop and non-drop)
• black and white video rate
• MIDI sequencers: 30 fps (drop and non-drop) 
The SH612 routes digital audio via 12 MADI In and 12 MADI Out ports, each with the 
capacity to receive or transmit up to 56 channels (up to 24-bit, 48 kHz). For sample 
rates exceeding 50 kHz, each MADI channel can carry only 28 digital audio channels. 
1.1.2 Power On Sequence
Attach the provided IEC-compatible power cable to the IEC inlet. Connect the other 
end to a wall outlet with appropriate plug adapter if necessary. The SH612 power sup-
ply automatically adjusts to any voltage in the range 110–240 V.
We recommend powering up the SH612 before the digital devices to which it is con-
nected. The SH612 conducts a brief self-test routine upon power-up and displays the 
firmware revision number. When the Main Menu is displayed, power up the attached 
converters.
NOTE: Please refer to the power up routine for System 5 before attempting to power the 
DF64 Digital Frames and the Pilot Computers. 
1.2 MADI Connections for the R-1
These are the standard MADI connections for the R-1:
• MADI Ports 1–4 are for converter or I/O devices
• MADI Port 7 is for AudioDeck 1
• MADI Port 8 is for AudioDeck 2
• MADI Port 9 is for AudioDeck 3
• MADI Port 10 is for AudioDeck 4
• MADI Ports 5, 6, 11, and 12 are for additional MADI devices that require a 
custom route to be used with the R-1 (see Section 3.1.5 - MADI Routing Menu).
