Using computer networking technology, the system allows you to transfer 24 channels of high-quality audio over an extremely long distance on a single lightweight cable. The digital advantage also brings with it easy installation, low cost, portability, and pain-free expansion.
40 channels of digital audio over a single Cat5e Ethernet cable. The S-1608/S-0816 system transfers a total of 24 channels of audio signal: 16 channels from the S- 1608 and 8 channels from the S-0816.
When using the S-4000-SP REAC splitter to extend the REAC cable or to split connect a separate S-1608 or S-0816 • When connecting the S-1608/S-0816 and S-4000S/S-4000H via REAC, see Page 66 for more information. 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.
S-4000R Remote Controller or a personal computer running the S-4000 Remote Control Software (S-4000 RCS). If RS-232C devices are connected to the REMOTE connectors on both the S-1608 and S-0816, the system can be controlled from either device (though only one remote device can control the system at any given time).
As it name suggests, the S-0816 FOH Unit’s main application is near the FOH mixing console. However, the S-0816 can be used anywhere you need to receive stage audio from the S-1608—at a monitor console, a multi-channel recording device, a broadcast feed, etc. Additionally, multiple S- 0816 units can be used for split destinations when connected to the system via an Ethernet switching hub.
5—S-1608/S-0816 System Overview S-4000R Remote Controller The S-4000R functions as a remote controller for the S-1608/S-0816 System. It can be connected to either the S-1608 or S-0816 unit, whichever is most convenient for you. • Input channel control—The S-4000R provides control over the S-1608/S-0816 System’s input channels.
Avoid using the S-1608 or S-0816 in sealed-type rack mounts. As this type of rack does not permit heated air within the rack to be expelled, the heated air is drawn into the S-1608 or S-0816 as a result, thus preventing adequately efficient cooling.
Use the following procedure to install the rack-mount brackets on the S-4000R. Disconnect the RS-232C cable from the S-4000R unit. Install the S-4000R rack-mount brackets with the supplied screws as shown in the following diagram. fig.6-08.eps S-1608/S-0816 Digital Snake Owner’s Manual...
6—Using the S-1608/S-0816 System Using the AC Cord Clamp The S-1608 and S-0816 units have AC cord clamps to prevent the cord from being pulled out accidentally. Remove only the screws shown in the following diagram (2 screws total), and detach the AC cord clamp.
Installing the Included Ferrite Core on Ethernet Cables One ferrite core is included with both the S-1608 and S-0816 for installation on Ethernet cables. Install a ferrite core on REAC cable SC-W100S (sold separately) or Ethernet cable near the RJ45 plug that will be connected to a REAC port.
Attaching the Rubber Feet Attach these as required, such as when you’re using the S-1608 or S-0816 without mounting it on a rack or the like. Peel off the double-sided tape from the rubber feet and affix the rubber feet at the locations shown in the following figure.
To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections. fig.6-14.eps_90 S-1608 16x8 (Master REAC device) 8 outputs from console 16 mic/line inputs...
6—Using the S-1608/S-0816 System Setting the REAC Mode fig.6-15.eps The S-1608 and S-0816 each feature a [REAC MODE] switch. This switch sets the REAC behavior of each device, and determines how audio is transferred throughout the system. Each unit’s [REAC MODE] switch must be set properly for correct system operation.
Setting the [REAC MODE] Switches fig.6-16.eps The [REAC MODE] switch on the S-1608/S-0816 is recessed from the front panel so that its setting can’t be changed inadvertently. To change the switch setting, use a blunt-tipped instrument such as a ball-point pen, mechanical pencil, etc.
On the S-1608: • Connect one end of the supplied AC power cord to a grounded AC outlet, and the other end to the POWER AC INPUT jack to provide power for the S-1608’s internal power supply. On the S-0816: •...
If the REAC cable is disconnected while [MUTE ALL OUTPUTS] is held, it’s possible that one of the S-1608 or S-0816 will remain in a muted state when [MUTE ALL OUTPUTS] is released. If this occurs, use the following procedure: Reconnect the REAC cable.
If you require a longer cable than the one provided, you can use an off-the-shelf RS-232C cable or fabricate your own. See Appendix B: Connector Information for an RS-232C pin out diagram. The S-4000R can be connected to either the S-1608 or S-0816. Connect it to whichever device location is most convenient for you.
Note that [MUTE ALL OUTPUTS] only mutes the outputs of the S-1608/S-0816 System, and not the outputs of other devices. Before connecting the audio outputs on the S-1608 and S-0816 units to the audio inputs of other devices, always turn down the volume or turn off the power on the receiving devices to prevent possible damage.
6—Using the S-1608/S-0816 System S-1608/S-0816 Audio Inputs The S-1608’s (S-0816’s) audio inputs are used to send source audio signals to the S-0816’s (S-1608’s) audio outputs. Connect the output of balanced audio devices (microphones, instrument outputs, etc.) to the balanced audio inputs on the S-1608 (S-0816) front panel.
(S- 1608/S-0816 Audio Inputs). When audio outputs from an S-1608 or an S-0816 are connected to inputs of external devices such as mixing consoles, please be sure to turn off the phantom power supply from these external devices.
Power is supplied to the S-1608/S-0816, and the POWER indicator lights up. The S-1608 and S-0816 units are equipped with protection circuits. A brief interval (a few seconds) after power up is required before the units will operate normally.
6—Using the S-1608/S-0816 System System Status Indicators The S-1608, S-0816, and S-4000R have system status indicators that allow you to monitor the integrity of the component connections when the system is powered up.

6—Using the S-1608/S-0816 System S-1608/S-0816 Input Channel Settings With the S-4000R unlocked, use the following procedures to adjust settings on the S-1608 and S-0816 input channels. To retain your changes to the S-1608/S-0816 system’s input channel settings, lock the S-4000R before powering down the S-1608/S-0816 System.
While a channel’s input pad setting (on/off) is changed, its output is temporarily muted to avoid noise. Phantom Power Each of the S-1608/S-0816 system’s inputs can supply +48 V phantom power to devices that require it, such as condenser microphones or active direct boxes.
6—Using the S-1608/S-0816 System Stereo Link The Stereo Link function allows you to link odd/even adjacent S-1608/S-0816 system’s input channel pairs (1/2, 3/4, etc.). When channels are linked, gain and pad settings made on one channel of the linked pair will be duplicated on the other. This can be convenient when audio devices with stereo outputs are connected to the S-1608 or S-0816.
The S-1608/S-0816 system features 10 user-storable memory presets. A memory preset contains channel settings (preamp gain, pad, phantom power, and stereo link) for all of the S-1608/S-0816 system’s 24 input channels. Using memory presets, you can quickly reconfigure the S-1608/S-0816 for frequently used audio input setups.
Using Two S-4000R Units in a Single S-1608/S-0816 System As discussed in Chapter 6, the S-4000R can be connected to either the S-1608 or S-0816. However, if you have a second S-4000R (available separately), you can connect one to each unit. This allows for control and signal monitoring of the S-1608/S-0816 System at the location of either unit.
100 memory presets—Store and recall up to 100 different S-1608/S-0816 input setups. • Integrated monitoring and control of multiple systems—You can connect up to four S-1608/S-0816 Systems to multiple RS-232C ports on a personal computer. This allows for control and signal monitoring of multiple systems from a single interface.
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.
See Page 38 for a discussion about the [REAC MODE] switches and how they affect REAC signal flow. With their power off, set the units as follows: On the S-1608, set the [REAC MODE] switch to M. On the primary S-0816 (usually at the FOH position), set the [REAC MODE] switch to S.
7—Advanced Use REAC Connections For the REAC connections: • Using Cat5e cables, connect the REAC port on the S-1608/S-0816 units to ports on the REAC splitter S-4000-SP or the switching hub. fig.7-03.eps REAC Splitter S-4000-SP or Switching hub S-1608 S-0816...
