Page 7: Product Overview
Product overview The KH 310 comes in two variants named “left” and “right” (see figure). It is also possi- ble to use a “left” in the “right” position, and vice versa. Both variants can also be used as a center loudspeaker. Information about positioning your KH 310 can be found from page 8. - Page 8 Back panel KH 310 A 5 ANALOG INPUT socket (XLR) 0 ACOUSTICAL CONTROLS switches 6 GROUND switch A Threaded inserts for Neumann mounting hard- (Connects/disconnects ground) ware 7 DISPLAY BRIGHTNESS switch B Handles with mounting holes (Dims the Neumann logo)

Installing and connecting the KH 310 CAUTION Danger of injury and material damage due to tipping/dropping of the product! If improperly mounted, the product and/or the mounting hardware (e.g. rack) can tip over or drop down. Always have the product mounted by a qualified specialist according to local, national and international regulations and standards. -
Page 10: Preparing The Room
To place the loudspeaker on a flat surface: Attach the supplied self-adhesive feet to the bottom of the cabinet. This reduces the risk of scratching the surface and acoustically isolates the loudspeaker from the surface. Preparing the room Arrange all acoustically relevant surfaces and objects symmetrically on either side of the listening axis of the room (left/right). - Page 11 0° -30° +30° Front Left Front Center Front Right -30° +30° Arranging the Copy the diagram “Installation angles” that can be found at the end of this operating manual. loudspeakers Place the diagram at the listening position or center of the listening area. Using a tape measure, place the loudspeakers at the same distance from the center of the dia- gram “Installation angles”.

Connecting/disconnecting the KH 310 to/from the mains power supply To connect the KH 310 to the mains power supply: Make sure that the on/off switch D is set to “0”. Connect the IEC connector of the supplied mains cable to the mains socket E. Power Source Connect the mains plug of the mains cable to a suitable wall socket. -
Page 17: Adjusting The Acoustical Level
The same loudspeaker installed in different positions in the same room may require different acoustical control settings. In a symmetrical installation, left/right pairs (front or back) will probably have the same acoustical control settings. Before using your loudspeaker system for the first time, calibrate the frequency response of the loudspeakers in the room in order to obtain the desired response. -
Page 18: Compensating For Video Delay (Lip Sync)
Set the OUTPUT LEVEL switch 9 and the INPUT GAIN control 8 of your loudspeakers so that the desired acoustic level is obtained. Recommended sound pressure levels: Application Sound pressure level Film 85 dB(C) Broadcast 79 to 83 dB(C) Music No defined reference levels If the Neumann logo flashes red, the loudspeaker‘s protection system has been activated. -

It might be possible to eliminate the noise by disconnecting the ground from the input signals (activating ground lift). To activate ground lift: Reconnect the signal cables and set the GROUND switch 6 to “LIFT”. This internally disconnects pin 1 of the ANALOG INPUT socket (XLR) 5 from the loudspeaker’s chassis ground (see diagram “Pin assignment of the XLR socket”... -
