Chapter 1: Technical Overview
Hardware Components
Nova73
The Nova73 forms the "heart" of the system, and is available in two sizes - Nova73 HD (10RU) or Nova73
Compact (7RU):
Nova73 HD (10RU) Nova73 Compact (7RU)
In each case, the front of the frame houses the:
·
Router Modules MKII - two central slots are available for a main and redundant Router Module. The
Router Module MKII (980/33) contains the summing matrix AND control system. The summing matrix
offers a 8k
2
capacity* router at 48kHz (or 4k
2
capacity at 96kHz). The control system runs on an
embedded Linux operating system, and stores both the application software and user data. Connections
are made via the two TCP/IP Ethernet ports:
o
ETHERNET A – connects to the control surface.
o
ETHERNET B – connects to the Lawo system network (to other Lawo devices; third-party controllers;
computers running configuration, maintenance or remote control software).
·
DSP and I/O Modules - 16* slots are available for plug-in DSP or I/O modules. Up to 8* DSP boards can
be fitted supporting a range of DSP configurations ; I/O options include AES/EBU, MADI, RAVENNA and
DANTE, see Nova73 Module Options . All modules are hot-pluggable enabling them to be be replaced
without affecting other aspects of the system. Further breakout formats are realised by connecting to
DALLIS I/O or Compact I/O stageboxes.
·
Power Supply Units - two slots are available for main and redundant power supplies .
The rear of the frame houses the:
·
Sync ports - accepting Wordclock, AES/EBU (AES3-id) or Video Black Burst (PAL or NTSC).
·
Alarm and control contacts - including a global alarm; prepare cold start; force redundant Router Module
takeover.
·
AES connector panels - for front-mounted AES3 I/O modules.
·
5* Cooling Fans - hot-pluggable and easily accessible.
