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. 4), and "IMPORTANT NOTES" (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. [. . . ] You can supply +48 V phantom power from the XLR connectors at INPUT 1 through 8. When a condenser microphone or the like is connected and supplying phantom power is required, switch it on by remote control. Refer to "Setting the Input Channel" (p. Preamp gain and phantom power on/off settings made by remote control remain in memory after the power to the S-0808 is switched off. You can ensure that the settings are stored in memory by locking the remote control before switching off the power. If you're using the S-4000R, press the [LOCK] button to make it light up, wait several seconds, then power off the S-0808. 11 Connecting Input and Output Devices Connecting Amps and Speakers Connect amps and powered speakers to OUTPUT 1 through 8. OUTPUT 1 through 8 on the S-0808 are male connectors. 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. No single cable should be longer than 100 meters. Do not use cables with cut or torn covering. Do not step on cables or subject them to undue stress. 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. Attach one ferrite core to the REAC cable connected to the S-0808. 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. [. . . ] 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?REAC has the following three operation modes, and the mode setting for each connected REAC device must be made correctly. Making the wrong settings may result in incorrect audio input and output. [. . . ]
