Danger due to high sound pressure levels WARNING Danger of hearing damage due to sudden high sound pressure levels! Audio signals that are present at switch-on of the product or that can be present during operation, can create sudden, very high sound pressure levels which can damage your hearing. XX Always lower the output level of the audio source before connecting it to the loudspeaker or starting it (pressing “play”). This loudspeaker can be used for commercial purposes.
The KH 310 studio monitor Thank you for purchasing a Neumann studio monitor. The KH 310 features a Mathematically Modeled Dispersion™ Waveguide (MMD™), flexible acoustical controls, various input options and an extensive range of mounting hardware. This allows the loudspeaker to be used in diverse acoustical conditions, with any source equipment and in a wide variety of physical locations.
Product overview The KH 310 comes in two variants named “left” and “right” (see figure). It is also possible 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 on page 7.
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. XX Always have the product mounted by a qualified specialist according to local, national and international regulations and standards.
Preparing the room X Arrange all acoustically relevant surfaces and objects symmetrically on either side of the listening axis of the room (left/right). X Minimize the sound that is reflected back to the listening position by using angled surfaces and/or acoustical treatment. This product has been optimized for use in recording studios. In order to not affect the quality of reproduction, make sure that the product is used in an EMC environment.
Arranging the loudspeakers X Copy the diagram “Installation angles” that can be found at the end of this operating manual. X Place the diagram at the listening position or center of the listening area. X Using a tape measure or a cable, place the loudspeakers at the same distance from the center of the diagram “Installation angles”. To ensure good imaging, do this at an accuracy of at least 1 cm (1/2").
The acoustical axis of the KH 310 starts from the midpoint of the midrange and tweeter drivers. x = 9.1 cm y = 17.0 cm X Always point the acoustical axis, in the horizontal and vertical planes, towards the listening position. The acoustical axis is a line perpendicular to the loudspeaker’s front panel along which the microphone was placed when tuning the loudspeaker’s crossover during design.
Connecting/disconnecting the KH 310 to/from the mains power supply To connect the KH 310 to the mains power supply: X Make sure that the on/off switch D is set to “0”. X Connect the IEC connector of the supplied mains cable to the mains socket E. D E Power Source X Connect the mains plug of the mains cable to a suitable wall socket. To disconnect the KH 310 from the mains power supply: EN 10 | KH 310 X Set the on/off switch D to “0”. X Pull the mains plug out of the wall socket.
Configuring and using the KH 310 Switching the KH 310 on/off X Set the on/off switch to: • “I” to switch on the loudspeaker. The Neumann logo lights up, provided that it has not been switched off by means of the DISPLAY BRIGHTNESS switch 7 (see page 13). • “0” to switch off the loudspeaker. The Neumann logo goes off. There is an approximate five second delay before sound can be heard from the loudspeaker in order to avoid noises (pops) from preceding equipment switched on at the same time.
Acoustical control Function Possible settings Bass Compensates for acoustical loading in the low frequency range due to nearby large solid boundaries (e.g. walls). 0, −2.5, −5, −7.5 dB Low-Mid Compensates for acoustical loading in the low-mid frequency range due to nearby large solid objects (e.g. mixing consoles or desks). 0, −1.5, −3, −4.5 dB Treble Compensates for insufficient or excessive high-frequency damping in the room.
Examples of sound pressure levels as a function of the input and output level of the KH 310: Input signal dBu 0 (0.775 V) 0 (0.775 V) +4 (1.23 V) −20 (77.
Cleaning and maintaining the KH 310 CAUTION Damage to the product caused by liquids! Liquids entering the product can cause a short-circuit in the electronics and damage or even destroy the product. XX Keep XX Before all liquids away from the product! cleaning, disconnect the product from the mains power supply. XX Use a soft, dry, and lint-free cloth to clean the product. Do not use any solvents or cleaning agents. XX Clean the cooling fins regularly. They should always be kept free from dust.
