Studio Monitors KH 120 II AES67 and
KH 150 AES67
Thank you for purchasing a Neumann studio monitor. The loudspeaker features a Mathemat-
ically Modeled Dispersion Waveguide (MMD™), DSP acoustical controls, a digital S/PDIF
input and output, network control capabilities, and an extensive range of mounting hard-
ware. This allows the loudspeaker to be used in diverse acoustical conditions, with any source
equipment and in a wide variety of physical locations. The KH 120 II AES67 / KH 150 AES67
represents the latest in acoustic and electronic simulation and measurement technologies to
ensure the most accurate sound reproduction possible.
The AES67 variants of the KH 120 II and KH 150 studio monitors support AES67 digital audio
signals and act as an interface in an existing AES67 audio infrastructure in the studio. The
integrated redundant AES67 audio network ports are fully compliant with ST 2110 and ST
2022-7 broadcast standards. The KH 120 II AES67 and the KH 150 AES67 also work with DAN-
TE®-generated AES67 network streams.
Depending on the size, Neumann’s two-way loudspeaker systems are designed for use as near
field monitors or as rearward or ceiling-mounted loudspeakers in larger multi-channel sys-
tems. They can be used in project, music, broadcast, and post production studios for tracking,
mixing, and mastering.

Setting up and connecting the loudspeaker
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 fall.
XAlways have the product mounted by a qualified specialist according to local, national
and international regulations and standards.
XUse the mounting systems recommended by Neumann and always provide sucient
additional protection against tipping or falling.
CAUTION
Damage to the product due to overheating!
If air cannot circulate properly around the cooling vents on the rear of the product, the
amplifier(s) may overheat, leading to premature activation of the thermal protection sys-
tem which limits the maximum output level of the loudspeaker. In rare cases, damage to the
product may also occur.
XNever cover the cooling vents.
XWhen installing the product into tight spaces such as wall recesses, maintain an air gap
of at least 5 cm around the top, rear and side panels of the product and provide sucient
air circulation. If necessary, use forced-air cooling.
For further information on setting up loudspeakers, please refer to the “Questions &
Answers” section on the product page at www.neumann.com.
For more information on building systems using Neumann loudspeaker products, please
refer to the Product Selection Guide at www.neumann.com
Preparing the loudspeakers
CAUTION
Risk of staining surfaces!
Some surfaces treated with varnish, polish or synthetics may suer from stains when they
come into contact with other synthetics. Despite a thorough testing of the synthetics we
use, we cannot rule out the possibility of staining.
XDo not place the loudspeaker on delicate surfaces.
To place the loudspeaker on a flat surface:
XAttach 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
XArrange all acoustically relevant surfaces and objects symmetrically on either side of the
listening axis of the room (left/right).
XMinimize 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 aect the
quality of playback, make sure that the product is used in an EMC (electromagnetically
compatible) environment, ideally without electromagnetic radiation from other devices.
EN
KH 120 II AES67 / KH 150 AES67 | 7
Positioning the loudspeakers
XCarry out the following steps very accurately, since the more accurate the physical arrange-
ment of the loudspeakers in the room, the more accurate the reproduction will be at the
listening position.
XObserve the recommended distances between the loudspeakers and your listening position:
Recommended listening distance for KH 120 II AES67: 1.0m – 2.0m
Min./max. listening distance for KH 120 II AES67: 0.75m – 4.0m
Recommended listening distance for KH 150 AES67: 1.0 m – 2.5m
Min./max. listening distance for KH 150 AES67: 0.75m – 6.0m
XAvoid positioning the loudspeaker at a distance (dwall) of 0.8 to 1.75m from the wall behind
the loudspeaker. When positioning bass-managed loudspeakers, avoid a distance (dwall) of
0.8 to 1 m from a solid wall behind the loudspeaker. Similarly, avoid these distances from
solid side walls or a solid ceiling. Respecting these positioning limitations reduces the
chances of dips in the low frequency response (comb filtering) caused by strong reflections.
XPrint out the “Installation angles” diagram that can be found at the end of this operating
manual.
XPlace the diagram at the listening position or the center of the listening area.
XUsing a tape measure, 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.
XIf the loudspeakers cannot be placed at the same distance from the listening position, com-
pensate for distance dierences > 1cm by delaying closer loudspeakers by 30 µs/cm. The
MA 1 – Automatic Monitor Alignment software automatically compensates for dierent dis-
tances between the loudspeakers and the listening position.
XArrange the loudspeakers as follows:
2.0 systems (stereo): ± 30°, plus optional subwoofer(s)
5.1 systems:
ITU-R BS.775-1: 0°, ±30°, ±110° (±10°), plus optional subwoofer(s)
(center, front left/right, surround left/right)
ANSI/SMPTE 202M: 0°, ± 22.5°, one surround array left and right, plus optional
subwoofer(s)
7.1 systems: 0°, ± 30°, ± 90°, ± 150°, plus optional subwoofer(s)
(center, front left/right, side left/right, back left/right)
3D systems See the recommendations from Dolby, DTS, Auro3D and
ITU-R BS.2051-0 for loudspeaker positioning.
The acoustical axis of the loudspeaker is between the bass and tweeter drivers.
XAlways 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 to tune the loudspeaker’s crossover when the monitor was
designed. Pointing the acoustical axis, in the horizontal and vertical planes, toward
the listening position or center of the monitoring area will give the best measured and
perceived transient response quality.
XPosition the loudspeaker so that there is a direct line of sight from the listening position to
the bass and tweeter drivers.
XMake sure that the ports are not blocked or partially covered.
XKeep sharp edges away from the port outlets, as they can cause air noise.

XUse an XLR adapter (not supplied) to connect unbalanced cables (e.g. RCA cables).
XUse this adapter directly at the source and connect the adapter via a properly wired bal-
anced XLR cable to the loudspeaker. The connection of pin 3 to ground should be as close as
possible to the source to maximize hum rejection on the cable.

KH 120 II AES67 / KH 150 AES67 | 9
XUse the following wiring if you want to make your own RCA-to-XLR cable:
Connecting digital AES3id and S/PDIF signals to the loudspeaker
XConnect the digital AES3id or S/PDIF output signal of your audio source to the DIGITAL S/
PDIF INPUT socket on the first loudspeaker (see figure below).
The loudspeaker only supports non-encoded AES3 and S/PDIF signals. Encoded signals
such as MP3, DTS or Dolby Digital are not supported. The cable connection must be
unbalanced with a characteristic impedance of 75 Ω.
Only one cable is needed for uncompressed AES3 and S/PDIF digital signals (single-wire
mode). They contain two audio channels: “subframe Aand “subframe B.” Usually, the
audio channels are:
Subframe A Subframe B
Left Right
Center LFE
Surround left Surround right
Back left Back right
A clock input is not required because loudspeakers are not audio sources and the con-
verters are clocked to a very stable internally generated clock source.
If the signal source is based on internal digital signal processing, it is recommended
that you choose a digital connection between the signal source and the loudspeaker.
This eliminates the need for additional signal conversion from digital to analog in the
source and from analog to digital in the loudspeaker. This also applies if you are con-
necting to an upstream DSP subwoofer (e.g. KH 750 DSP). This should be connected to
the loudspeakers via its digital output.
Note that the supplied digital signal often has a maximum signal level, and that the
level in the source is often not adjustable. Therefore, before making the digital connec-
tion, set the OUTPUT LEVEL switch on the loudspeaker to 94dB SPL and the INPUT GAIN
knob to -15dB.
XConnect the DIGITAL S/PDIF OUTPUT socket on the first loudspeaker to the DIGITAL S/PDIF
INPUT socket on the second loudspeaker.
XSet the INPUT SELECT switch on the left loudspeaker to S/PDIF L and the INPUT SELECT
switch on the right loudspeaker to S/PDIF R. The CONTROL switch must be in the Local
position.

The settings of the first loudspeaker in the signal chain are not looped through to the
second loudspeaker. Each loudspeaker must be configured separately.
When using a daisy chain connection as shown here, the signal from the second loud-
speaker is not delayed relative to the first loudspeaker.
