User manual ROLAND S-0808

[. . . ] Owner's Manual Before using this unit, carefully read the sections entitled: "USING THE UNIT SAFELY" (Owner's Manual p. These sections provide important information concerning the proper operation of the unit. Additionally, in order to feel assured that you have gained a good grasp of every feature provided by your new unit, Owner's Manual should be read in its entirety. The manual should be saved and kept on hand as a convenient reference. Copyright © 2010 ROLAND CORPORATION All rights reserved. [. . . ] Use female XLR connectors to make the connections. fig. output-connection. eps The signal level that is output is +4 dBu (nominal, maximum output: +22 dBu). If the input to the connected amps or powered speakers is too high and the audio output is distorted, adjust the gain using the input attenuator for the amp. Adjusting by lowering the preamp gain on the S-0808 may result in a poor signal-to-noise ratio. 12 Connecting REAC Devices Before Making REAC Connections Cables for REAC Connections With Digital Snake and V-Mixing Systems, digital transmission of audio signals is performed by means of REAC (Roland Ethernet Audio Communication). Compared to analog transmission, this system is extremely resistant to external noise, but in very rare instances, noise can occur. Selection of the wrong cable and incorrect cable handling can cause noise. Observe the following points when using cables. · · · · · Ensure that the cables used for connections conform to the Cat 5e (Enhanced Category 5) standard. Do not wind cables too tightly or sharply bend them. To maintain transmission quality, use of the following optional REAC cables is recommended. · 100-meter cables: · 20-meter cables: SC-W100S (cable only) or W100S-R (with reel) SC-W20F REAC Connector Cover When using an ordinary available Ethernet cable (as opposed to optional cables) to connect a REAC device, fit the included REAC connector covers onto the REAC ports. Electromagnetic noise may be a problem if these are left unattached. fig. fit-connector-cover. eps * Attaching a REAC connector cover is not necessary when you're using an optional REAC cable (described above). When using an ordinary available Ethernet cable, be sure to use a cable that conforms to the Cat 5e (Enhanced Category 5) standard. About Ferrite Cores The S-0808 comes with two ferrite cores. Clamp the ferrite core onto the cable at a location near the plug at the end of the cable, pressing down on the ferrite core until it clicks closed. Attach another ferrite core to the power cable from the external battery. fig. fit-ferrite-core. eps * When attaching a ferrite core, be careful to avoid pinching your fingers. * When connecting a REAC device, use a cable that has a ferrite core attached to it. 13 Connecting REAC Devices Connecting S-0808 Units to One Another You can configure a simple digital snake system having 8-channel inputs and 8-channel outputs by installing one S-0808 at the stage and another one at the mixing desk (front of house [FOH]). fig. 0808-0808. eps STAGE FOH M (Master) S (Slave) * Set the operation mode of the S-0808 at the stage to M (master) and the mode of the S-0808 at FOH to S (slave). The signals from INPUT 1 through 8 on the master unit are output to OUTPUT 1 through 8 on the slave unit, and the signals from INPUT 1 through 8 on the slave unit are output to OUTPUT 1 through 8 on the master unit. Make the settings for the REAC mode only when the S-0808 units are powered off. When connecting two S-0808 units directly using a REAC cable, attach external batteries to both S-0808 units and power them via their DC IN ports. For more information about external batteries, refer to "Using an External Battery" (p. The output level of OUTPUT 1 through 8 on the S-0808 is fixed at +4 dBu (nominal, maximum: +22 dBu). When connecting the unit to a mixer at the FOH, make the connection to an input connector capable of a maximum +22 dBu signal. 14 Connecting REAC Devices Connecting to a REAC Splitter (S-4000D/S-4000-SP) Connecting an S-4000D or S-4000-SP or an ordinary available Ethernet switching hub lets you split the input signals of the REAC master device. When you want to output audio not to speakers but to recording or broadcast equipment, make the connections as shown below. fig. via-S-4000D. eps STAGE FOH M (Master) S (Slave) Master Device Slave Device S-4000D Split Device Split Device Recording Room SP (Split) * Set the operation mode of the S-0808 unit at the recording equipment to SP (split). Set the unit at the stage to M (master) and the unit at FOH to S (slave), in the same way as when connecting two S-0808 units to one another. Make the settings for the REAC mode only when the S-0808 units are powered off. When power is provided by an S-4000M, S-4000D, or other source device providing REAC EMBEDDED POWER, no external batteries are required. [. . . ] Check that S-0808 is booted correctly and then connect the S-4000R. No power is supplied by the external battery. Is the battery compatible with the rated voltage of the S-0808?When receiving power from an external battery, the voltage must be between 12 V and 18 V. Also, batteries for broadcast video-cameras have a feature to display the remaining charge. Check the remaining charge before connecting. Input and Output No input or output is possible. Is the operation mode set correctly? [. . . ]
