Lynx Pro Audio OCS Software V2.0 Quick User Guide
1. Introduction
The O.C.S. (Online Control System) software is available for all self-powered DSP-incorporated Lynx Pro Audio cabinets supplied with an Ethernet module kit. O.C.S. provides detailed cabinet behavior information and real-time monitoring via the user's PC, allowing control of single cabinets or entire systems. It features a Parametric EQ with 6 configurable filters, delay up to 90 ms, and controls for preset, gain, mute, polarity, phase, air absorption compensation, and SOLO mode.
The software operates via Ethernet (wired or wireless). Upon installation, it automatically detects connected cabinets and displays them in the O.C.S. window. The software monitors RMS levels, delay, EQ, compression, output levels, power module temperature, air absorption compensation, and cabinet angulation in real-time.
Screenshot Description: The OCS software interface is shown, displaying a list of connected devices (e.g., LXV8psf, ADP12Mpsf, ADP26psf) with their IP addresses and status. It also shows controls for Gain, Polarity, Mute, Delay, and Air Absorption Compensation for individual cabinets, along with a frequency response graph.
2. Overview
The O.C.S. main screen is designed for simplicity, providing access to all basic functions. The interface includes a Tools bar, a list of connected devices, and a visualization window.
The Tools bar offers the following options:
- Project management: New, Open, Save, Save Project As
- Project options
- Ethernet configuration
- Climate options (Temperature, Humidity)
- Show Frequency Monitor / Response
- Online View
The window displaying connected devices provides functions such as searching for devices, creating/deleting folders, expanding/shrinking the device tree, and opening all connected devices. It also shows device general information like Model, Name, IP, MAC, and Firmware Version.
Screenshot Description: The OCS main interface is displayed, highlighting the Tools bar with icons for Project, File, Ethernet, Climate Options, Settings, and monitoring functions. It also shows the Device Information panel listing connected cabinets and processors, and the main visualization window.
3. Cabinet Control
The OCS software opens a dedicated window for each connected cabinet, offering detailed information on its behavior. Users can adjust delay (up to 90 ms), change presets, gain, mute status, and polarity. Air absorption compensation and SOLO mode can also be activated. Clicking the "Show EQ" button reveals the Parametric EQ controls.
Within the cabinet control window, users can view:
- Cabinet model and IP address
- Cabinet name
- Power module internal temperature
- Gain control (with +/- 0.1dB increments)
- Mute function
- Polarity control
- Delay control (0-90 ms)
- Air Absorption Compensation (enabled/disabled, with meter/feet settings)
- Preset selection
- Cabinet inclination (if available)
Screenshot Description: A detailed view of a single cabinet's control window is shown. It displays the cabinet model (LXV8psf), IP address, internal temperature, and controls for Gain, Polarity, Mute, Delay, Air Absorption Compensation, and Preset selection. The "Show EQ" button is visible.
3.1. Equalization Control
Activating the "Show EQ" button expands the cabinet window to reveal the Equalisation control section. The software supports up to 6 filters per channel, offering flexibility with configurable filter types such as adaptable or constant Q, All Pass, Band Pass, Notch, HP Q, LP Q, and High/Low Shelves.
EQ settings are saved with the current preset. If a cabinet is disconnected and reconnected, the EQ settings remain. Changing the preset will reset user-applied EQ changes, returning the cabinet to EQ bypass mode.
The Equalisation section includes:
- Bypass EQ / Reset EQ buttons
- Filter Type selection
- Filter Number selection (up to 6 filters)
- Frequency adjustment (+/- 1 Hz increments)
- Q (Quality Factor) adjustment (+/- 0.1 increments)
- Gain adjustment (+/- 0.1 dB increments)
Screenshot Description: The Parametric Equalization window is displayed, showing controls for Bypass EQ, Reset EQ, Filter Type (e.g., Parametric Q adap), Filter Number, Frequency, Q, and Gain sliders. It also indicates how to increase/decrease values and write exact levels.
4. View Section
The Monitor online icon indicates the connection status: green means online and data capture is active, while red means disconnected. From the View section, users can activate or hide the Frequency Response window.
The Frequency Response window displays the cabinet's frequency response. When EQ is in bypass mode, the response is shown as a hyphenated line. Users can also display the EQ phase by activating the "Show Phase" function in the Legend. Graphic colors for each cabinet can be customized and are saved upon closing the software.
Screenshot Description: The Frequency Response window is shown, featuring a graph with axes for Gain and Frequency. A legend indicates controls for Cursor, Show, Phase, and EQU. The frequency response curve is displayed. Another part of the screenshot shows a color selection dialog for customizing graphics.
5. Settings Section
This section allows users to configure various software options. The climate part enables setting temperature and humidity, which directly influences the Air Absorption Compensation for connected cabinets.
Clicking the "Ethernet devices" icon opens a window for setting Ethernet parameters. This includes viewing and managing the Device List (MAC Address, Name, Device, IP Address, Status) and Network Information (Environment, Local Host, Local IP, Local Port). Users can change device IP addresses and names, and identify devices (making their Ethernet LED blink).
The "Options" icon allows configuration of general project data, including Response Window limits (Axis dB Maximum/Minimum Value), Default Folder, Project Name, Installation details, Engineer, and Comments. It also offers startup options like loading the last project, auto-saving, and restoring default values.
Screenshot Description: The "Ethernet configuration" window is shown, listing connected devices with their IP addresses and status. It also displays network information and fields to change the device IP and name. Another screenshot shows the "Options" window with project settings and general preferences.
6. Ethernet Configuration Guide
Configuring an Ethernet network for OCS is straightforward. Two connection methods are available:
- Direct connection: PC to cabinet using a crossed Ethernet cable.
- Via Switch/Hub: Connecting through an Ethernet Switch or Hub using a standard CAT5 cable.
To configure the network, a static IP address must be set for the computer. This is done via Windows settings: START > CONFIGURATION > NETWORK CONFIGURATION.
The process involves accessing the properties of the "Local Area Connection" (or similar network adapter), selecting "Internet Protocol (TCP/IP)", and then configuring the IP address, Subnet Mask, and Default Gateway. It's recommended to obtain IP settings from the network administrator or use a static IP within the network's range (e.g., 192.168.1.xxx).
After configuring the PC's static IP, connect to the line array system using the OCS software. In the OCS software, navigate to the Initial Screen and select "Ethernet Device" from the Configuration menu.
Within the OCS software's "Ethernet configuration" window, users can manage device IPs and names. The network environment requires the first three sets of IP numbers to match between the PC and the devices for successful communication. If the network environment differs, connection issues may arise, especially with certain Windows versions.
To check PC network settings, use the Command Prompt (START > ALL PROGRAMS > ACCESSORIES > Command Prompt) and type ipconfig. This command displays the PC's current IP settings.
The ping command can be used to verify if an IP address is already in use. Typing ping [IP address] will show if a device responds, indicating the IP is occupied. A lack of response suggests the IP is free.
Screenshot Description: Several screenshots illustrate the Windows network configuration process. One shows the Windows Start menu navigation to Network Configuration. Another displays the "Local Area Connection" properties, highlighting the selection of "Internet Protocol (TCP/IP)". A third shows the TCP/IP Properties window for setting static IP addresses. Subsequent screenshots show the OCS "Ethernet configuration" window and Command Prompt windows displaying ipconfig and ping command outputs.
