Power On Sequence, PAL/SECAM 25 fps

Euphonix SH612 Studio Hub User Guide	Getting Started

If necessary, the SH612 can distribute synchronization signals via four AES Sync (AES/EBU), Word Clock, video, or MTC outputs to System 5/Max Air 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)

NOTE: Euphonix does not recommend using the SH612 for synchronization distribution. System 5 and Max Air installations should use synchronization distribution amplifiers with separate sync lines going to each component (no looping). Please see the syn- chronization notes in your console’s install guide.

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.

The MADI spec allows 64 channels of audio per port - however, Euphonix’ VariSpeed technology occupies some of this bandwidth and thus each port supports 56 channels at

48 kHz.

1.1.2Power On Sequence

Attach the provided IEC-compatible power cables to the two IEC inlets. Connect the other ends to wall outlets with appropriate plug adapters if necessary. The SH612 power supply 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 devices.

NOTE: For console installations, please refer to the power up routine for System 5/Max Air- before attempting to power the DF64 Digital Frames and the Pilot Computers.
