EF BUS
The EF BUS page allows the user to configure how to combine the bus signals from the other linked Vortexes and control which echo canceller reference is sent to other devices as the Bus Reference. Since there can be up to 8 Vortexes linked together and each device can put 4 different signals on the bus (W, X, Y, and Z), there are 4 submatrices to allow flexibility in how the signals from other devices get mixed together and get presented to the main matrix. Figure 11 shows the EF BUS submatrix and the fact that there are 4 submatrices and the inputs are WB0, . . . WB7 for the W bus, XB0, . . . , XB7 from the X bus, and the same for the Y and Z busses. The cross points can be changed by left clicking on the cell and adjusting the gain. Cross points can be muted by right-clicking on the cell (an unmuted crosspoint is indicated by a bolded black value; muted is indicated by a gray value). Any of the rows of the matrices can be configured as a mix-minus which allows the user to work with a simple mix-minus sum of all the other devices. If more complicated mixing from other devices is required, any of the matrix rows can have arbitrary cross points gains.
EXPORTING THE ECHO CANCELLER REFERENCE ON THE EF BUS
You can set which echo canceller reference is assigned as the Bus Reference to be used by all other linked Vortexes in the EXPORTED SIGNALS section on the page. The

DEVICE PARAMETERS
choices are REFERENCE 1, REFERENCE 2, or NONE. In this example, WB0 is grayed out because we are working with Device 0. Any of the cross points can have arbitrary gains.
MATRIX MIXER
The Matrix Mixer in Figure 12 allows the user to map any input to any output with an arbitrary gain in dB applied from -100 dB to +20 dB. Muted cells are shown in light gray while unmuted cells are shown in bold. To set the gain of a single cross point, "left" click on the cell. To set the gain of a collection of cross points click and drag to select a rectangular area. A slider control with a text box will appear to allow you to change the gain, select mute/unmute, or, on Inputs 1-8, choose the gated version of the Input. If you are using signals for reinforcement and specifically want the gated signals at an attenuated level, then set the gated crosspoint to the desired level such as -15 dB. In general, the gain of gated signals should be set to 0 dB since the matrix will sum the automixed signals and use the appropriate weightings of the signals based on the information from the automixer.

DEVICE PARAMETERS
To change the gain of an entire row or column you may simply click on the column or row header (any of the labels 1-D on the columns or the rows) to see a collection of sliders as shown in Figure 13.

The outputs R1 and R2 correspond to the echo canceller references REF 1 and REF 2. While these outputs are not physical outputs on the product, they allow you to build the echo canceller reference without using physical outputs from the device. In the example in Figure 12, we used stereo program audio and consequently had a local left output (Output C) and a local right output (Output D) in the room.
