[. . . ] If the speaker's voice sounds distorted, reduce the line output level by turning control ¸ counterclockwise. Installing a system with up to eight loudspeakers By connecting two loudspeakers to each loudspeaker output, you can connect up to eight loudspeakers to the Soundfield System: The Soundfield System should generate a uniform sound field in the entire room. Therefore, install the loudspeakers so that two loudspeakers are not exactly facing each other. This can lead to cancellations, resulting in a nonuniform sound field. Connecting the loudspeakers When installing a system with up to eight loudspeakers, make sure that the individual loudspeakers have an impedance from 4 to 8 ohms. When using more than one loudspeaker, make sure that the individual loudspeakers have the same polarity (+/­). Never connect the loudspeaker cables to the ground and never allow the cables to come into contact with another cable or metal casing parts. During operation, the ends of the loudspeaker cables must never come into contact. The connected device records the same signal that can be heard in the room through the loudspeakers. If possible, connect the sound recording device via its line input (LINE IN, REC. For correct connection of the different audio devices, please refer to the diagrams at the left. Adjusting the recording level The recording level is independent of the setting of the volume controls · and ». It is, however, dependent on the setting of the line input sensitivity control (LINE IN) µ. control µ adjusts the input level of the connected audio device. The recording level of the line output can be adjusted from 0 to 700 mVrms (corresponds to minus infinite to up to 0 dBU). The sound recording device is connected via its line input (LINE IN, REC. IN, AUX IN, TB IN or similar): Turn control ¸ clockwise as far as possible and adjust the input level of the sound recording device. The sound recording device is connected via its microphone input: Set the input level of the sound recording device to maximum and use control ¸ to adjust the recording level so that, during loud passages, distortion is avoided. Note: If control ¸ is turned counterclockwise as far as possible, no audio signal will be available at the line output . If you have connected two mono sound recording devices, the control adjusts the recording level of both devices. With one Soundfield System, up to three speakers can speak simultaneously in the same room. For installing the system described above, you require additional SK 500 bodypack transmitters and EM 500 rack-mount receivers (u "Recommended accessories"). [. . . ] press the SET button four times to select the "Ch no" menu. "Ch no" appears on the display; after a short pause the currently assigned channel number is indicated. The new channel number starts flashing on the display and becomes effective immediately. Note: Channel numbers which have already been assigned to a fixed frequency memory are skipped! [. . . ]
