S-1608/S-0816 Digital Snake Owner’s Manual 57
Traditionally, when using an analog snake system, audio splits are taken directly at the source. This
requires the use of expensive and bulky transformer-based audio splitters, as well as an additional
analog snake for each split destination. Besides this, analog signal splitting can reduce the source
signals’ quality and greatly increase the potential for introducing noise into the entire sound
reinforcement system via ground loops and RF interference.
Using REAC, splitting the stage audio in an S-1608/S-0816 System is extremely easy. Simply add a
REAC splitter or a switching hub and an S-0816 unit for each split destination, hook them together
with Cat5e cables, and you’re ready to go! Besides this setup convenience, REAC splits provide pristine
audio quality—once the input signals are converted to digital data in the S-1608, they can be split as
many times as you wish with absolutely no loss in quality.
What You’ll Need
To split the S-1608’s 16 channels of input audio, you’ll need:
• a REAC splitter S-4000-SP or an Ethernet switching hub with enough ports to connect each REAC
device.
• an additional S-0816 unit for each split destination.
• REAC cable SC-W100S or Cat5e cables.
Ethernet Switching Hub Requirements
To work with REAC, an Ethernet switching hub must meet the following requirements:
• 1000BASE-T transmission speed (IEEE802.3ab, Gigabit Ethernet)
• Support for 100BASE-TX devices (IEEE802.3u, Fast Ethernet)
• Bi-directional (full-duplex) communication
Connect REAC devices only to switching hub ports that support 100BASE-TX.
Ethernet connection standards recommend using straight-through cables to connect devices to the
ports on a switching hub, and crossover cables when connecting hub-to-hub. However, some
switching hubs provide ports that allow the use of either crossover or straight-through cables—the
port will detect the type of cable that’s connected and adjust the signal transfer accordingly. Consult
the switching hub’s documentation to determine which type of cables you should use with it.
