1. Introduction

Welcome to Power Core.

About this Manual

This document describes all aspects of Power Core, including its hardware, installation, licensing, configuration,

remote control, networking and maintenance.

Power Core can be installed as a stand-alone device, or as the integrated DSP Core for a Lawo control surface.

If installing with a control surface, you will find more information on the surface components in the relevant

manual.

Look out for the following which indicate:

Notes - points of clarification.

Tips - useful tips and short cuts.

Attention - alert you when an action should always be observed.

Further Information

Mechanical drawings and data sheets (including weights and dimensions) are available from the Download-

Center (after login).

3. Product Overview

Power Core is a 1RU, 19-inch DSP Core, IO interface and routing matrix. It can be installed as a stand-alone

processing engine / matrix, or as the integrated DSP / IO Core for a Lawo control surface.

Audio Interfacing

As standard, there are two RAVENNA/AES67 streaming ports, four optical MADI ports and eight GPIOs for

contact closures. Optionally, up to eight plug-in IO cards can be fitted to the rear expansion slots to add Mic/Line

In, Line Out, Studio IO, AES3 IO, MADI or DANTE IO.

Signal Processing

All units include DSP to create sources and summing buses with signal processing: EQ, Dynamics, Delay,

Limiting, De-essing and Automix, available for some signal paths. The total number of resources is determined by

the licensed feature set. Thus, you can purchase a suitable package for your application.

Licensed Feature Sets

Power Core must be purchased with a license to "unlock" the system resources. Several main license packages

are available. Where applicable, a main package can be expanded by purchasing one or more add-ons. The

main license plus any add-ons must be installed onto a USB memory stick connected to the DONGLE port.

The Configuration

All programmable functions are defined by the system configuration. This is stored on the device's control

system and read during boot-up. The configuration can be edited using the ON-AIR Designer software, and a

new version uploaded via the control network. The configuration possibilities are extensive and include the

definition of audio inputs and outputs; sources and buses; signal processing; and MF Key functions.

Power

The device provides dual power feeds: AC and DC. If both inputs are connected, then AC provides the main and

DC the redundant power supply. To use the DC input, you will need an external 12V DC power supply; this can

be ordered separately.

Remote Control

If Power Core is connected to a control surface (via the CANbus), then all resources can be controlled from the

console. In addition, Power Core supports a range of remote control options (via TCP/IP) including VisTool MK2

and Ember+.

During installation and setup, a HTML interface known as the "Web UI" can be used to set the IP address, check

system statuses and manage the RAVENNA/AES67 streaming connections. Some of this information is also

visible on the front panel display.

4. The Hardware

4.1 Front View

1 SYSTEM Display & Menu Control

The front panel display can be used to edit local device parameters such as the IP address.

2 STATUS LED

The STATUS LED indicates the health of the device and sync status. If the LED is blinking at regular intervals,

then the device is working properly; the LED color indicates the sync status.

3 RESET button - warm start

Press this button to perform a warm start. The button is recessed to prevent accidental operation.

A warm start will reboot the device. Do NOT perform a warm start while live on air!

4 DONGLE

Use this port to connect the USB memory stick containing your system's WIBU license(s). A safety cap is

available to prevent accidental removal of the dongle. If fitted, you will need a T10 star tool to remove the cap.

5 CAN

The CAN bus port connects to the control surface frame.

6 RS 422

The serial port can be used for remote control (e.g. for playout systems), MACKIE HUI interfacing to a Digital

Audio Workstation and for debugging. It is usually left unconnected.

7 CONTROL A & B (via SFP)

The two CONTROL ports connect other devices to the Power Core control system.

Applications include remote control via TCP/IP; networking to other products; updating firmware and uploading

a configuration. Usually only the CONTROL A port is connected. If both ports are used, then redundancy can

be implemented via LACP.

8 RAVENNA/AES67 A & B (via SFP)

The two RAVENNA/AES67 interfaces stream audio to and froman IP network.

The streams are fully compatible with the SMPTE ST2110-30/31, AES67 and RAVENNA standards. To achieve

redundant streaming, compatible with SMPTE ST2022-7, you must use both interfaces: A and B.

The streaming network must be properly managed and configured.

Power Core User Manual Version: 6.6.0/3 9/539

4. The Hardware

9 MADI 1 to 4 (via SFP)

The four MADI ports can be used to connect multi-channel digital audio to the device (up to 64 bi-directional

MADI channels per port). Ports 1&2 and 3&4 can be dual-redundant (defined by the ON-AIR Designer).

10 WCLK IN & OUT

WCLK IN can be used to connect an external wordclock sync reference. Other reference options are PTP,

MADI or Internal.

WCLK OUTalways provides an output of the current system reference.

11 GPIO

This connector provides 8 x GPI (optocouplers) and 8 x GPO (silent and self-healing relays) for local signaling

and switched functions.

For Power Core Edge or Super Audio Node, you must purchase the GPIO add-on license to activate these

signals.

4. The Hardware

4.2 Rear View

12 Expansion Card Slots x 8 (optional)

Up to 8 plug-in IO cards can be fitted to the expansion slots at the rear of the frame. All cards are hot-

pluggable. Options include: MIC/LINE, LINE IN, LINE OUT, STUDIO IO, AES3, AES3id, MADI and DANTE.

13 CASE

The CASE grounding screw should be used to ground the frame.

14 12V DC Input & AC Mains Input

Every device comes with dual power feeds: AC and DC. To use the DC input, you will need an external 12V DC

power supply. The 955/50-80 power supply can be ordered separately.

If both inputs are connected, then AC provides the main and DC the redundant power supply.

Power Core MUST be connected to the mains using the power cable supplied with the system.
