Multi-way top speakers, one-way subwoofers
This example is connected using analogue XLR. The
left and right channels are daisy chained per channel.
This setup can be used with, or without remote kit.

Without a preamp, with multiple sources
This example features two multi-way models that are
equipped with the remote kit. The two FusionAmps are
linked via the S/PDIF I/O for remote communication
and this also functions as a daisychain for the digital
domain. If toslink is selected in the master(1), the
slave(2) can be configured to listen to the S/PDIF
daisychain.
A couple of examples are given. These examples are
meant as reference. Other configurations are also
possible. Read all examples, since valuable principles
are explained in different examples. These examples
assume your have read the other chapters in this
guide. In the schematic drawing, the remote link is
depicted as a dotted line:
Other connections are depicted as dashed line and
may be digital, analogue, balanced ore unbalanced.
Setup with preamp or directly from source
This is the most simple setup. Use your (existing)
preamp for source selection, volume etc. The
FusionAmps can be connected analogue or digitally,
depending on your preamp. This setup can be easily
expanded with additional FusionAmp speakers. This
setup can be used with, or without a optional remote.

Multi-way top speakers with dual mono sub.
You can choose for a full-digital setup here. The
master (1) can be used as input and can be daisy
chained to the other modules. A digital signal carries
both left and right channel. Using HFD the channel can
be selected and filters need to be configured
accordingly. Module 2,3 and 4 must be set as slave.
You can also choose for a BTL setup in the subwoofers,
using only one driver and the multi-way FusionAmp
configured as BTL.

High level input
In this setup we add one (or two) FA one-way models
to act as active subwoofer. If only one subwoofer is
added, both left and right channel should be
connected to the respective high-level input of that
one subwoofer. If two subwoofers are added, connect
them in respect to the corresponding channel.
In this setup a remote kit does not add much value,
since volume is controlled by the existing amplifier,
just as source selection. The gain of the subwoofer(s)
can be adjusted using the gain control knob.

Using the remote (optional)
All modules can be extended with the Fusion IR
Receiver set. This set contains a PCBA with IR receiver
and bi-colour LED, and the necessary cables.
Additionally you need a Hypex Remote. Installation
instructions for this kit are supplied with the product.
Principle of master and slave.
To work with the remote feature, you need to
understand the principle of master and slave modules.
In principle, the module to which the Fusion IR
Receiver Kit is connect, should be configured as
master. Additionally, the other FusionAmps in your
setup should be configured as slave.
The IR receiver PCBA can be used in both master and
slave devices, only in slave devices the IR functionality
is disabled. The bi-colour LED can then be used to
indicate the status of the particular slave device. Note
to correctly configure master and slaves to prevent
unexpected behaviour.
How to link the slave modules to the master?
The S/PDIF I/O is utilized to communicate between
the modules. The master module modulates a
communication link on to the S/PDIF I/O. Use a decent
quality 75 ohm coaxial cable to link the modules. The
maximum total cable length should be kept under 25
meter. A maximum of three slave modules can be
connected to one master. Refer to the application
examples for more information.
What to do with a mixed model setup?
If a mixed setup is created (one-way models mixed
with multi-way models) the master should be a multi-
way model. Since a mixed configuration has
conflicting inputs (digital vs high-level), the one-way
models are muted if a digital source is selected at the
master. If this is undesirable, consider a two-way
model in BTL or dual-mono as subwoofer amplifier.
Analogue or digital and remote?
The remote feature can be used with all types of
inputs. Thus, analogue balanced and unbalanced can
be used, providing that the remote link (S/PDIF) is
connected. In case of analogue inputs, the S/PDIF link
only carries the remote signal.
