Integrator Series Room Combine 788
Introduction
Integrator Series products are designed with specific
applications in mind. The Room Combine 788 is a complete
solution for selectively combining or separating automixing,
paging and background music in up to eight (8) rooms in
hotels, banquet halls, schools, and conference venues.
Today’s hospitality and meeting centers demand
sophisticated audio systems that are easy to operate.
The 788 delivers with complete signal processing,
automixing and combining of eight (8) microphones and
four(4)backgroundmusic(BGM)sourcesintoasmany
as eight (8) rooms, each with comprehensive loudspeaker
management.Combinationsofaudio,page,andBGM
routing, including non-adjacent spaces, are assigned in the
setupsoftware.Buteaseofsetupisonlyhalfthestory.
The other half is real time user control. Our ARC-SWK
wall panel (sold separately) is perfectly suited for audio
sourceselectionandvolumecontrol.MultipleARC-SWK’s
dynamically synchronize as spaces are combined and
separated. Preset room combinations can be recalled
from the 788’s front panel, the ARC-2i wall panel, or
your favorite third-party control system. The 788 also
easily accommodates “soft wall” sensors with its eight (8)
analog control inputs for a simple, foolproof triggering of
combinations.
As with all of the Integrator Series products, ease of
integration is key. Software Wizards effortlessly guide
connection, wall panel programming, and graphical layout
of the rooms and their relationships. Room Combine 788,
Engineered by Symetrix to save integrators time and money.

WARNING: When designing an ARC network, one must be careful
not to double power any ARCs. If all pins on the CAT5 connections are
used, power can travel over the CAT5 cable and reach any ARC on that
particular chain. Power over CAT5 could potentially come from the ARC
that is powered locally and then daisy-chained via CAT5 to other ARCs or
directly from a particular ARC’s terminal block connections. In general, we
recommend using only one type of power connection on
the ARCs, either the RJ45s (with CAT5 cable) or the terminal blocks
but not both.

Unbalanced Connections:
Unbalanced out to balanced in
The RCA connector and the 1/4” TS connector are
unbalanced connectors. However, the wiring differs
depending on if they are sending to, or receiving from a
balanced connector.
In this example, the unbalanced connector is sending signal
to a balanced connector. When wiring this connection,
use a shielded twisted pair cable. The balanced side wires
the same as a standard, balanced connection. On the
unbalanced side, you wire the white (minus) wire together
with the ground. This provides some common mode
rejection at the balanced input.
Unbalanced Connections:
Balanced out to unbalanced in
When your output requires a balanced connector, but you
are sending signal to an unbalanced input, the rules change.
Use a single strand shielded wire. Wire only to the plus and
ground terminals of what would typically be the balanced
connector.

Integrator Series Room Combine 788
Network Configuration
TThe 788 is setup and controlled by a host computer via
Ethernet. This requires the host computer to be connected
to the 788 directly via a standard CAT5 Ethernet cable,
indirectly via an Ethernet switch, or via an existing Ethernet
network.
The primary difference between the three methods of
connection is that in the first two, the 788 software
application assumes there is no DHCP server or other
network infrastructure in place. It assumes the 788 is using
a self-generated IP address and adjusts its connection steps
appropriately. In the third method, it is assumed that a DHCP
server and/or router with DHCP server are already present
on the existing network so the 788 may already have
obtained an IP address. Consult your network administrator
if in doubt.
General Notes
1. The 788 boots up with DHCP enabled by default. This
means that as soon as you connect it to a network, it will
look for a DHCP server in order to obtain an IP address. If
a DHCP server is present, the 788 will get its IP address
from it. This process may take several minutes. With your
PC attached to the same network and thus getting its IP
address from the same DHCP server, all will be ready to
go.
2. If your network does not have a DHCP server, the 788
will not be able to obtain an IP address. While waiting,
the 788 will default to a private IP address in the range
of 169.254.x.x where x.x is the last four alphanumeric
charactersofthe788’sMACaddress.The788’sMAC
address can be found on a sticker on the bottom of the
788 or within the front panel System menu. When there is
no DHCP server present to assign IP addresses to either
the 788 or your PC, you may need to configure your PC
with a static IP in the range of 169.254.x.x with a Subnet
Maskof255.255.0.0inordertocommunicatewiththe
788 in a direct connect mode. However, if your PC is
using the default network settings, it should also have
automatically self-assigned a similar private IP address
in the range of 169.254.x.x, and if this is the case, you
should be able to connect to the 788 directly. Even if the
PC’s default settings have been changed, the 788 will try
to establish communications by setting up appropriate
routing table entries to reach devices with 169.254.x.x
addresses.
3. In the case of the first two methods (direct connection
and indirect connection), the 788 software will attempt
to set-up appropriate routing table entries for a seamless
connection regardless of the IP addresses of your PC
and 788. However, under Windows® Vista, administrative
privileges are required to allow the 788 software to
modify the routing table. For best results, launch the 788
software while logged in as an administrator, or choose
to run the software as an administrator. Note: To run
a program as the Administrator under Vista, right click
on the program’s icon or shortcut and choose “Run as
administrator”.
4. The 788 will display its current IP address, subnet
mask, and gateway as well as other useful information
onthefrontpaneldisplaywheninSystemMode.To
enterSystemMode,holddowntheMenubuttonfor5
seconds. Then the up and down arrow keys can be used
to move between various displays. This information may
be useful for troubleshooting.
Network configuration of the 788:
Connecting to the 788 from a host computer on the
same LAN
Boththe788andthehostcomputerrequirethefollowing
3 items:
1. IP Address - The unique address of a node on a network.
2.SubnetMask-CongurationthatdeneswhichIP
Addresses are included in a particular subnet.
3. Default Gateway (optional) - The IP address of a device
that routes traffic from one subnet to another. (This is only
needed when the PC and 788 are on different subnets).
If you are putting the 788 on an existing network, a network
administrator will be able to provide the above information or
it may have been provided automatically by a DHCP server.
For security reasons, it is not recommended to put the 788
directly on the Internet. If you do, a network administrator
or your Internet Service Provider can provide the above
information.

If you are on your own private network, directly or indirectly
connected to the 788, you may allow the 788 to choose
an automatic IP address or you may choose to to assign it
a static IP address. If you are building your own separate
network with static assigned addresses, you may consider
using an IP Address from one of the ”Private-Use” networks
noted in RFC-1918:
