Project Description

Salzbrenner Media Polaris evolution

Polaris evolution is a highly flexible, scalable, modular audio mixing system based on Ethernet connectivity, which allows multiple tasks to be performed simultaneously. Each user interface can be personalised to an unprecedented degree to suit personal preferences or the task in hand. User interface options include control from tablets and other mobile devices. Software modules are available to optimise the system for use in live sound, theatre and post production or broadcast applications.

Hardware:

  • POLARIS access: base control surface with:
    • 16 P&G faders
    • 16 dual concentric rotary controls
    • 48 illuminated push-buttons
    • 19” touch display
  • POLARIS view: large screen interface, with:
    • 21.5” multi-touch display
    • Docks to access module; motorised angle adjustment
    • Provides enhanced display of console functions and allows control of all parameters
  • POLARIS scala system DSP frame offers:
    • Up to 256 input and 256 output DSP channels
    • Ethernet connection to control surfaces
    • One or two matrix cards, 64 or 128 matrix buses
    • MADI interface to NEXUS I/O rack or external equipment
    • Can be cascaded to create larger DSP matrix or to provide redundancy
    • Processing can be shared by several control surfaces
    • Silent operation

Software:

  • Live module (supplied as standard) provides:
    • 6-band EQ, dynamics, delay and de-esser per channel
    • VCA and mute groups
    • Effects modules
    • Library system for channel strip and effects storage
    • DAW control
    • Mobile device integration
  • Theatre and Post Production module adds:
    • Powerful show-based automation system
    • Extended automation grouping
    • Support for surround audio formats
  • Broadcast module adds:
    • AFV operation with pre-channel curves and timing
    • Extended automation grouping
    • Support for surround formats
    • N-1 matrix
    • Loudness metering interface

System:

  • Control surfaces connect to scala frame via WLAN/Ethernet
  • scala frame provides up to four 64-channel MADI I/O
  • Modular NEXUS I/O rack can host any combination of analogue and digital I/O
  • NEXUS connects to scala via MADI
  • IP network architecture gives instant expandability

The Stagetec NEXUS routing matrix may form part of a Polaris evolution system; NEXUS is fully modular and can be configured with whatever mix of audio I/O formats is needed.

Description

The Polaris evolution from Salzbrenner represents a radical development in the concept of audio mixing. Recognising the increasing standardisation of MADI as an audio transport format in broadcast, post production, theatre and live sound applications, it combines hardware and software elements to provide users with precisely the control facilities they need, where they need them, with minimal connectivity issues.

The Polaris evolution system comprises three primary hardware components: the access 16-fader control surface, the view multi-purpose touch screen and the scala DSP frame.

The scala DSP frame is a 3U 19” rackmounting unit: as well as the DSP core, it provides a 256 x 256 routing matrix and card slots to accommodate optical MADI I/O ports. In facilities where MADI is the standard audio transport format, no additional I/O hardware is required. However, analogue and digital inputs and outputs may be added at will by the addition of a Stagetec NEXUS audio routing system (see separate website entry), which can be configured with any combination of analogue (mic or line), AES3, HD SDI, DANTE or further MADI I/O modules.

Two scala modules may be cascaded to add a further 384 inputs, resulting in a system mix architecture of 640 into 256. Furthermore, scala units may be duplicated at network level to provide a fully redundant system.

scala communicates with the control surface components using IP over Ethernet; connections are via standard Cat 6 cable and IT architecture.

The access console is a 16-fader control surface; multiple access consoles may be physically interconnected to provide a larger surface if one is required; an inter-module script area is also available. As well as 16 motorised faders, each access is fitted with 16 dual concentric rotary encoders, 48 recessed, illuminated push buttons and a full-width, multi-purpose touch-sensitive display. The user can choose the channel parameters to be displayed – input levels, EQ curve, send levels, etc. The dual encoders are “soft” and their function assigned according to the currently displayed parameters.

Local I/O may be added to provide talkback and headphone monitoring, using Dante™ as the audio transport format: a Dante™ client card is fitted as standard and communicates with an optional Dante™ card in scala.

A view module, consisting of a 21.5” touch screen, may be added to any access console to greatly increase the amount of information that can be displayed. view is attached to the rear of access, and is motorised, to optimise the viewing angle to suit operator and ambient lighting conditions. view has its own powerful internal processor, to permit it to be used as a stand-alone module.

Polaris evolution systems are supplied as standard with a Live software module, which provides a wide range of standard mixing console features, including per-channel 6-band EQ, delay, dynamics and de-essing, plus multiple PFL/Solo busses, VCA and Mute groups, and EQ, dynamics and effects processing per-bus. Extension software modules for Theatre and Post Production, and for Broadcast applications are also available, which add further mixer features relevant to these types of task, such as scene-based automation, N-1 outputs and surround sound capability.

Control of audio in a Polaris evolution system is not limited to the dedicated hardware control surfaces; being a network-based system, it is compatible with tablet PCs and other mobile devices via WiFi.
