®
BUILDING YOUR SYSTEM WITH MULTIPLE VORTEXES
The following is a checklist for building a system with multiple Vortexes:
1. Assign Inputs.
2. Assign Outputs.
3. Configure submatrix (the EF Bus).
4. Configure your echo canceller reference.
1. ASSIGN INPUTS
Assign each audio source to an input. Remember to include the conferencing equip-
ment such as the EF200 Phone Add or a video codec and any program audio.
2. ASSIGN OUTPUTS
Try to assign as many outputs as you can to each Vortex to make a simpler submatrix.
Remember that Outputs 1-8 can also be used as outputs of the matrix. The bussing
can get very complicated very quickly if you choose to spread your outputs over sev-
eral units.
3. CONFIGURE THE SUBMATRIX
To link multiple Vortex devices together, use the submatrix on the EF Bus.
The EF Bus
The EF Bus is a high speed, low delay digital bus that includes the W, X, Y, and Z
audio busses as well as the echo canceller reference and remote control information
(for other Vortexes) and can link up to 8 Vortex devices. All busses include NOM
information and can be used for sharing microphone inputs, or for sharing mono or
stereo program information.
Crosspoint Mix Minus Bus. Each Vortex device in the system can create four
output mixes (W, X, Y, and Z) and place them on the bus. Each device also can create
three input mixes each from the W, X, Y, and Z busses of the other devices (for a total
of 12 mixes). The mixes can have crosspoint gains on the signals from the other
devices. See Figure 1 below. All 12 mixes become inputs to the main matrix and can

and Z bus outputs.

Figure 1. W, X, Y, and Z submatrices.
EF Bus Reference. In a system with multiple devices, if all devices need the
same echo canceller reference, one device should be designated to put its echo cancel-
ler reference (either Ref 1 or Ref 2) on the EF bus to be used as the EF Bus Reference.
All other Vortexes may use the EF bus reference as the reference for their echo can-
cellers, or they can use their own internal references. The references may include a
mix of any input, with crosspoint gains, including W, X, Y, and Z busses.
NOM Bus. All busses on the EF Bus contain NOM information. See “NOM
Active” on page 29 of the Vortex Reference Manual for more information on how
NOM attenuation is applied.
Note. The EF Bus must be connected so that the EF BUS OUT of one
Vortex device is connected to the EF BUS IN of another Vortex.
Connecting EF BUS IN to another EF BUS IN (or EF BUS OUT to
EF BUS OUT) will not work. See“Connector Pinouts” on
page 43 for pinout of Cat 5 cable.
4. CONFIGURE YOUR ECHO CANCELLER REFERENCE
Review what inputs need to be included in your echo canceller reference — See
“Build Your Echo Canceller Reference (if not using Preset 0)” on page 13. of the Vor-
tex Reference Manual. Remember that each microphone needs an echo canceller ref-
erence. If all microphones are in the same room and use the same reference,
configure the echo canceller reference on one Vortex and assign it to the EF Bus as
the EF Bus Reference. Only one Vortex out of multiple units linked together can put

an echo canceller reference on the EF Bus. For each additional unit, assign the echo
canceller reference to use the EF Bus Reference.
For systems with more than one room, you will need to use the W, X, Y, or Z sub-
busses to share the echo canceller reference in your additional rooms if the EF Bus
Reference has already been assigned to the EF Bus.
AUTOMIXER SETTINGS FOR MULTIPLE VORTEXES
When using more than one Vortex in your room system, you have several possibilities
for how you configure the automixer. Each Vortex can operate as one of the follow-
ing:
•
•
•
•
One automixer, independent of other Vortexes linked to it
Two automixers, independent of other Vortexes linked to it
One large automixer, sharing automixer functions with other Vortexes linked to it
Two large automixers, sharing automixer functions with other Vortexes linked to
it
Figure 2. Vortex Automixer Global Parameters in Conference Composer Software
Automixer and Bus
Mixer Settings
To operate the Vortex in any of the above possibilites, two global parameters need to
be changed: the AUTOMIXER and the BUS MIXER (see Figure 2). The AUTOMIXER
parameter chooses which automixer the input channel will be on (this is changed
either on the AUTOMIXER page in Conference Composer or on the MATRIX MIXER
page).
The BUS MIXER parameter is used to assign one of the two internal automixers to one
of the eight EF Bus automixer groups. For example, consider three Vortexes each of
which has four microphones assigned to Automixer 1 and 4 microphones assigned to
Automixer 2. Now, if each of these Vortexes sets their Automixer 1 to have Bus
Mixer 5 (the Bus Mixer is also referred to as the Bus ID), then the three automixers
(one from each Vortex) will work as a single automixer containing 12 (3 x 4) micro-
phones. Setting BUS MIXER to 0 means that the automixer is not grouped on the EF
Bus.
Operating as an
Independent
Automixer
To set the Vortex to operate as an independent automixer (or two independent mix-
ers), set the BUS MIXER parameter to 0, or to a number that is different from any other
automixer group currently in use on the EF Bus.

Operating as One
Automixer with
To set the Vortex to operate as one automixer across several Vortexes, set the BUS
MIXER parameter on all Vortexes to the same automixer group.
Multiple Vortexes
Example: Room
Combining
Let’s take a room combining setup as an example. You have 3 rooms, each with 8
microphones, therefore needing 3 Vortexes. For the purposes of this example, the 3
rooms can operate as 3 separate rooms, 2 rooms with 12 mics each, or one large room.
When the system is split into 3 Rooms, the BUS MIXER option should have the fol-
lowing settings:

BUILDING YOUR SYSTEM WITH MULTIPLE VOR-
CONNECTING MULTIPLE VORTEXES
Up to 8 Vortexes can be linked together at one time. Each unit in the chain must have
a unique Device ID. Use the EF Bus to link multiple Vortexes together.
The following steps should be followed to connect the EF Bus:
•
•
Connect the RS-232 remote control device to the first Vortex in the chain.
Connect the provided Cat-5 cable between the EF BUS OUT of the first device,
and the EF BUS IN of the second device.
Note. The EF Bus must be connected so that the EF Bus In of one
box is connected to the EF Bus Out of another. Connecting
the EF Bus In to another EF Bus In (or Out to Out) will not
work.
•
•
Connect another Cat-5 cable between the EF BUS OUT of the second device and
the EF BUS IN of the third device, and so on.
Terminate the chain of Vortexes using the instructions below.
Terminating the
Vortex
The Vortex must be terminated with the provided EF Bus terminator. Place a termina-
tor in the EF BUS IN of the first device in the chain and also in the EF BUS OUT of the
last device. If you lose the terminator provided with your Vortex unit, see “Making an
EF Bus Terminator” on page 45 for information and instructions on how to make one.

EchoFree Devices
If you are linking multiple Vortexes, you must use the EF bus to link the Vortexes to
each other. If you are linking a Vortex to other EchoFree devices, such as the EF200
Phone Add, for RS-232 control, use the ASPI bus. See Figure 4 below. The ASPI
Bus does not need to be terminated.
