Step 4 — Set Mixer Mode

Once your physical G-Link network is established and unique G-Link
DEVICE ID numbers for each AP400 on the network are established,
the mixer mode must be set. There are three mixer-mode settings (see
Figure 11, left): master-single (default), master-linked, and slave.

Master-single must be used when only one AP400 is used in a system.

Master-linked denotes the master AP400 unit when more than one
AP400 is on the network; only one AP400 can be designated as master-
linked when multiple AP400s are used in a system.

Slave is used for all networked AP400s that are not designated as mas-
ter-linked or master-single. If two AP400s are part of the same system,
one must be set with the master-linked parameter, the other must be
set with the slave parameter.

A system is defined as one or more AP units that communicate to per-
form mixing functions. A system may consist of one unit in master-sin-
gle mode or several units that work together with one master-linked unit
and multiple slave units. Systems may be G-Linked together for easy
reconfiguration as shown in Figure 11. The physical location on the G-
Link network determines which system individual units belong to. In
Figure 11, for example, AP400 Device 4 has been designated as master-
linked, the units located below this unit on the G-Link network constitute
System 3, while units above it belong to different systems. The entire
network could be easily reconfigured into one system by changing the
mixer mode on Devices 3 and 4 to slave units which would then refer to
the only master-linked unit on the system: AP400 Device 0.

To set Mixer Mode:

1. Press the SYSTEM button. Scroll through the menu until you see

MIXER MODE.

2. Press ENTER, then scroll through the three options.
3. Press ENTER at the appropriate option to select it.
4. Repeat this process for all AP units in the G-Link network.

Hardware installation is now complete.

Step 5 — EC Reference

When multiple AP400 units are linked together and will be using only
one output channel to drive the speaker system, this output must be
defined as the acoustic source which will be used by all of the linked
AP400s. In other words, the output which the master unit will use as the
EC reference must be identified to the slave units via the G-Link. (See
page 38 for details on Echo Cancellation Setup for multiple units.)
