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.

Delivery includes

1 KH 120 II AES67 or KH 150 AES67

4 Self-adhesive feet

1 Quick guide

1 Safety instructions

1 Power cord (EU, UK, USA, China or Korea)

About this manual

This operating manual describes the physical setup and autonomous operation of the loud-

speaker. For information on how to control the speaker over a network using the MA 1 – Auto-

matic Monitor Alignment software, please refer to the software help.

The MA 1 – Automatic Monitor Alignment software is available for macOS and Windows and

oers the following advantages:

• Precise adaptation to your listening preferences

• Calibration to the listening environment

• Optimized stereo imaging

• Perfect matching of amplitude and phase to subwoofers

• Compensation for suboptimal listening situations

• Settings for system level, display brightness, delay and other features

The MA 1 – Automatic Monitor Alignment software is available at www.neumann.com.
