Installing and connecting the KH 80 DSP
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.
X
Always have the product mounted by a qualified specialist according to local, national
and international regulations and standards.
X
Use the mounting systems recommended by Neumann and always provide sucient
additional protection against tipping or dropping.
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 system
which limits the maximum output level of the loudspeaker. In rare cases, damage to the
product may also occur.
X
Never cover the cooling vents.
X
When installing the product into tight spaces such as wall recesses, maintain an air gap
of at least 5 cm (2") around the top, rear and side panels of the product and provide sufficient air circulation. If necessary, use forced-air cooling (e.g. in OB vans).
For information on installation, please refer to the supplied “Getting Started Quickly”
supplement. This will help you set up the loudspeakers in a way that will give you the
best acoustic performance from the system.
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 suer from stains when they
come into contact with other synthetics. Despite a thorough testing of the synthetics used
by us, we cannot rule out the possibility of staining.
X
Do not place the loudspeaker on delicate surfaces.
To place the loudspeaker on a flat surface:
X
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
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 not to aect the
quality of reproduction, make sure that the product is used in an EMC (electromagnetically compatible) environment.

Positioning the loudspeakers
X
Carry out the following steps very accurately, since the more accurate the physical arrangement of the loudspeakers in the room, the more accurate the reproduction will be at the
listening position.
X
Observe the recommended distances between the loudspeakers and your listening position
(imperial dimensions are approximate):
• Minimum: 0.50 m (2')
• Recommended: 0.8–1.75 m (2'6"–6')
• Maximum: 3.0 m (9')
X
Avoid positioning the loudspeaker at a distance “d

distance “d
avoid these distances from solid side walls or a solid ceiling. Respecting these positio-
” of 0.8 to 1 m (2'6"–3') from a solid wall behind the loudspeaker. Similarly,

y = 12.9 cm
X
Print out 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, 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
1 cm (

X
If the loudspeakers cannot be placed at the same distance from the listening position, compensate for distance dierences > 1 cm (
1
/
") by delaying closer loudspeakers by 30 µs/
2
cm (76 µs/inch). Delay can be set directly in the loudspeaker using the Neumann.Control
software.
X
Check the location of the loudspeaker cabinet. This depends on the application:
• 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°, arrays to the surround left and to the surround 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 KH 80 DSP is located at the midpoint of the bass and tweeter drivers.
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.
Pointing the acoustical axis, in the horizontal and vertical planes, towards the listening
position or center of the monitoring area will give the best measured and perceived
sound quality.

Switching the KH 80 DSP on/off
On/Off
X
Set the on/o switch to:
• “ON” to switch on the loudspeaker. The Neumann logo lights up solid red while the
DSP system boots up. After approximately 5 seconds it turns white indicating the loudspeaker is ready to be used. If the logo brightness has been set to less than 100% in the
Neumann.Control software, it will be dimmed or o after the bootup phase is complete.
• “OFF” to switch o the loudspeaker. The Neumann logo switches to red for a short moment
and then goes o.
There is a 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. Conversely, switching o the loudspeaker immediately mutes the audio.

SETTINGS switch
The SETTINGS switch has two functions which can be turned on or o independently.
STANDBY
If the SETTINGS switch has been set to one of the two AUTO STANDBY = ON positions, the
KH 80 DSP will switch to standby after 90 minutes.
Standby means that the network interface, signal processing circuitry and power amplifiers
are all powered down. Standby mode is automatically deactivated when a suciently large
audio signal is detected at the analog input. The time taken to resume normal operation and
hear sound is 5 seconds. It is possible to change the time before standby mode is activated
using the Neumann.Control software.
Standby can be disabled by moving the SETTINGS switch to one of the two AUTO STANDBY =
OFF positions.
CONTROL
If the SETTINGS switch has been set to one of the two LOCAL CONTROL positions, the KH 80 DSP
will not react to network commands. Control of the loudspeaker will be from the backplate
only.
If the SETTINGS switch has been set to one of the two NETWORK CONTROL positions, the
KH 80 DSP will react to network commands from the Neumann.Control software. The other
backplate controls will be ignored.
If the SETTINGS switch is set to NETWORK CONTROL but there is no network connection and
active Neumann.Control software, the last used network configuration will be used.
If you have configured any settings via the Neumann.Control software and you remove the
network cable, the current settings will stay active.
By switching from network control to local control you can easily switch between a configuration measured in the Neumann.Control software and settings made directly on the loudspeaker.
This can make sense if you want to temporarily use the loudspeaker in a dierent location than
your measured studio environment.
The loudspeaker does not lose its settings even when disconnecting it from the network or the
mains supply.
Resetting the KH 80 DSP
To reset the KH 80 DSP internal controls to their factory default values:
X
Switch on the KH 80 DSP.
X
While the Logo is flashing during the boot up phase, move the SETTINGS switch up and
down repeatedly.
The Logo will then light up with a rosé flutter flash before reverting to white.
Firmware update
Firmware updates are done via the Neumann.Contol software. When it is opened it surveys
the network for loudspeakers and checks if the firmware is up to date. If a firmware update is
needed, you will be prompted to follow the on-screen instructions. It takes approximately 10
seconds per loudspeaker to do the update.
EN
KH 80 DSP | 11
Adjusting the frequency response using the backpanel controls
When the LOW MID control is set to FREE STANDING or, via the Neumann.Control software,
the acoustical controls have been set to 0 dB, the KH 80 DSP loudspeaker is designed to have
a flat frequency response in anechoic conditions. When the loudspeaker is installed in your
monitoring environment, the response changes. The same loudspeaker installed in dierent
positions in the same room may require dierent acoustical control settings. In a symmetrical
installation, left/right pairs (front or back) will probably have the same acoustical settings.
X
Before using your loudspeaker system for the first time, align the frequency response of the
loudspeakers in the room in order to obtain the desired response.
X
Repeat the above step if you change the physical conditions in your studio.
X
At your listening position, determine the frequency response of each loudspeaker.
X
Use the ACOUSTICAL CONTOL switch to compensate for the acoustical loading in the lowmid frequency range due to nearby large solid objects (e.g. mixing consoles, desks or computer screens).
ACOUSTICAL CONTROL switch Possible settings
Low-Mid Free Standing (0 dB),
Small Desk (-1.5 dB),
Medium Desk (-3 dB),
Large Desk (-4.5 dB)
Adjusting the acoustic level
X
On your KH 80 DSP loudspeakers, set the OUTPUT LEVEL switch to 94 dB SPL and the INPUT
GAIN control to -15 dB.
X
Play a broadband pink noise test signal that is set to -18 dBFS (Europe) or -20 dBFS (USA)
on the mixing console’s output level meters.
X
Measure the sound pressure level at the listening position using a sound level meter with
the following settings:
• “C”-weighted
• slow integration time
X
Set the OUTPUT LEVEL switch and INPUT GAIN control 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. To
avoid this and achieve the desired output level, use larger loudspeakers or add a bass managed subwoofer to the system.
