  • Page 21: Running Compass With Virtual Galileo

    Running Compass with Virtual Galileo Virtual Galileo provides a software simulation of the Galileo 616 hardware. It allows you to be productive when Galileo hardware is not available for your use; it also allows you to create new projects without risking changes to a Galileo unit that is currently in use.
  • Page 22 A new Galileo tab will be added to the top of the window. The text “virtual” will be shown above the Galileo tab name. You may now use the Virtual Galileo device as if it were a real Galileo 616 unit, though without audio signal.
  • Page 23 A new Galileo tab will be added to the top of the window. The text “virtual” will be shown above the Galileo tab name. The Virtual Galileo will now perform in place of the Galileo 616 unit. IMPORTANT: When you disconnect the Virtual Galileo all settings will be lost.
  • Page 24: Running Compass With Galileo

    Galileo units is simple. Network Connections In brief, you can connect your workstation directly to a single Galileo 616 unit, or connect your workstation and multiple Galileo 616 units to a network switch or router. Many modern computers support a network standard named Auto-MDIX which allows you to connect the workstation computer directly to the Galileo without an intervening network switch or router.
  • Page 25 In addition, permitting access to port 8000 on the Galileo 616 units will allow web access to the Galileo log files.
  • Page 26 A full discussion of networking issues is beyond the scope of this manual. If you encounter problems with connecting your workstation computer to a Galileo system, please refer to the Galileo Hardware Reference Manual for details, consult your local hardware installation technician, or contact Meyer Sound technical support.

    CHAPTER 2: COMPASS OVERVIEW Compass Controls Figure 2.1. Illustrated User Interface Element Names On each Compass page are controls for setting values; selecting, isolating, and link grouping channels; enabling or bypassing parts of the signal path; selecting a page or sub-page of controls;...
  • Page 29 COMPASS USER GUIDE Some pages have tabs within the page itself, providing access to a series of sub-pages that further organize controls. On the Input Processing and Output Processing pages these tabs can be hidden or the sub-pages collapsed, freeing up additional space for the plot curve display. The color of the tab indicates the network status of the Galileo unit.
  • Page 30 CHAPTER 2: COMPASS OVERVIEW Using Buttons Buttons perform an action when pressed, perhaps selecting a channel, toggling a function, or displaying a new page. Visually, the buttons look like traditional on-screen buttons. Buttons almost always have a label (unassigned Link buttons are the notable exception);...
  • Page 31 Visually, the encoder looks like a round knob inside a square casing. When the knobs are colored the colors correspond to the colors of the Galileo 616 front panel encoders. Unlike the controls described so far, the encoder is used by dragging: click and hold the mouse button, then drag the cursor around to change the value in the value box.
  • Page 32 CHAPTER 2: COMPASS OVERVIEW Using Faders Faders are shown on the input and output master pages. Visually, they look like traditional physical console faders: a slider that can be dragged up or down to adjust the gain value, with value demarcations beside it. The gain value is displayed in both the associated value box and on the slider knob.
  • Page 33 COMPASS USER GUIDE Parametric sub-page. When the mouse is hovered over a handle, an expanded handle is displayed: three vertical bars intersecting a horizontal bar. The horizontal bar, amber in color, corresponds to the gain level. The center vertical bar, red, corresponds to the frequency centerpoint.

    +26 dBu (standard) or +20 dBu (studio mode). The Galileo 616 also has a standard Ethernet connection for communication with Compass. In facilities with more than one Galileo, the Ethernet connections will be made to a network hub or router, allowing Compass to communicate with all Galileos simultaneously.
  • Page 35 Output page. Detailed instructions are provided in Configuring Audio Inputs and Outputs (p. 28). Network configuration is managed through the Galileos page. Find Galileos will, in most situations, auto-discover network-connected Galileo 616 units. Detailed instructions are provided in Running Compass with Galileo (p. 6). 2. Label Galileos, Inputs, and Outputs Although most Galileo installations are relatively simple, it is still important to provide useful names for the Galileos and their input and output channels.
  • Page 36 To make your work progress more quickly, learn to use the Using Shortcuts (p. 24). Although the Galileo 616 has a very low noise floor and wide dynamic range it is best to work the mixing console at its optimum levels. The Galileo will accept the maximum output of most mixing consoles, allowing you to restrict gain control in the Galileo to the adjustment and balancing of signals.
  • Page 37 It is a superlative tool for determining optimal loudspeaker placement and appropriate acoustic environment correction. When connected to a Galileo 616, the Galileo is used as a line switcher, eliminating the need for any additional patching.

    Each Galileo 616 unit can receive six channels of audio input signal and send sixteen channels of output signal. The Galileo 616 can accept the line level output of most mixing consoles and can directly drive Meyer Sound self-powered loudspeakers to full output.
  • Page 47 AES input does not require selecting an input voltage range. Configuring the Galileo 616 Audio Outputs The adjustable output range provides two level output settings to drive Meyer Sound self-powered products.

All globally linked Galileos will now be set to the same environment conditions. You should now set the distances between the loudspeakers and listening area.
  • Page 68 Bypassed buttons in the Output Processing pages do not affect array correction. Configuring M Series Array Correction This setting assumes the output channel(s) on the Galileo 616 unit are connected to a Meyer Sound M Series curvilinear or line array.

The control setting controls will now be hidden, providing significantly more vertical space for the plot.
  • Page 73 Parametric EQ Compass provides a digital version of the Meyer Sound CP-10 filter set through its five-band (inputs) and ten-band (outputs) complementary phase parametric equalizers. As a second-order filter, it is ideal for treating interaction artifacts.
  • Page 74 EQ. With TruShaping, phase shift is kept to a minimum, making it ideal for shaping low frequency signal and the associated subjective qualities perceived by the listening audience. When VX-1 Mode is enabled, the EQ curve will duplicate the functionality of the Meyer Sound VX-1. Setting TruShaping EQ Values There are several methods available to set the value for a TruShaping EQ control: Drag a horizontal handle to adjust gain.
  • Page 75 COMPASS USER GUIDE Using VX-1 Mode In VX-1 mode the upper two gain handles are locked together, such that the upper frequency handle has no effect on the EQ curve. This creates a smooth, broad high-frequency boost or cut. When VX-1 Mode is first enabled the TruShaping EQ plot does not change: this preserves your TruShaping design until you deliberately adjust one of the upper handle components.
