The NET 1 network system
The NET 1 allows you to control and monitor Sennheiser wireless microphone
and monitoring systems.
Its main feature is frequency management, significantly simplifying the set
up of complex wireless systems by
y scanning the channel banks and automatically assigning the frequencies to
the connected rack-mount devices and
y wirelessly transferring data to the portable devices.
One NET 1 device with up to 10 connected rack-mount devices is a suitable
tool for configuring your system. A second, daisy-chained NET 1 allows you to
configure systems comprising up to 20 devices, without the need for a PC.
Applications with up to five NET 1 devices, i.e. multi-channel systems with up
to 50 channels, can be controlled via a PC and the supplied “Wireless Systems
Manager” (WSM) software. These multi-channel systems are connected to
the PC via Ethernet connections.
The WSM software enables real-time monitoring as well as remote controlling
of all relevant device parameters during live operation, ensuring an excellent
overview of the system at all times. In addition, the WSM software allows you
to integrate and control devices of the Sennheiser 3000/5000 series.
The following Sennheiser systems can be configured using the NET 1:
For correct operation, only transmitters and receivers that are equipped with
the same compander system can be combined with each other:
Sennheiser is continuously improving the NET 1 and the WSM software. We
therefore recommend that you register on our homepage at
www.sennheiser.com/net1 to regularly receive a newsletter providing
information on the NET 1, the WSM software and future software updates.

Connecting the devices
Note:
Only use original Sennheiser cables to connect the devices (see
“Accessories/replacement parts” on page 29).
The NET 1 has five connection groups. Devices can be connected either to the
sub-D socket or to the two RJ 10 sockets of a connection group, not to both:
Connecting evolution wireless G2 devices
왘Use separate RJ 10 cables to connect the service interface (DATA) of each
evolution wireless G2 device to the desired RJ 10 socket on the NET 1.
왘When connecting an EM 550 G2 twin receiver, use two cables to connect
the individual receivers DATA A / DATA B to two RJ 10 sockets on the NET 1.
Note:
For multi-channel systems, you can daisy-chain several NET 1 devices.
Make sure that within the network the number of connected devices per
frequency range does not exceed the number of free preset frequencies
within a channel bank.
When using more than eight receivers from different evolution wireless G2
series, at least one EM 500 G2 or EM 550 G2 receiver per frequency range
must be connected to the first connection group. The preset frequencies of
these receivers are then used for assigning the frequencies.

there are two operating modes:
1. “Stand Alone” operating mode (without a PC):
yone NET 1 with up to 10 connected devices
ytwo daisy-chained NET 1 with up to 20 connected devices
2. “Remote” operating mode (with a PC):
yup to five daisy-chained NET 1 connected to a PC with up to 50
connected devices
Note:
In “Remote“ operating mode, the frequency scan can only be performed
using the “Wireless Systems Manager” software (see the instructions for
use of the “Wireless Systems Manager” software).
The rack-mount receivers and transmitters (IEM) may well have different
frequency ranges.
Performing a frequency scan in “Stand Alone”
operating mode
With the frequency scan, the NET 1 searches for free frequencies for multi-
channel operation (see the instructions for use of the evolution wireless G2
devices).
There are the following possibilities:

receiver as described from page 18 and
y then using a rack-mount receiver as
described from page 21

18
Performing a frequency scan for wireless monitoring
systems (IEM)
For wireless monitoring systems, the frequency scan is performed using the
EK 300 IEM G2 portable receiver. The frequencies of a selected channel bank
are then assigned to all SR 300 IEM G2 rack-mount transmitters of this
frequency range. Subsequently, the frequencies are transferred to the
corresponding portable receivers.
Switching the portable transmitters off
왘Switch off all portable transmitters that are to be configured via the NET 1.
Preparing the frequency scan
왘Press and hold the MODE button on the NET 1.
The NET 1 selects one rack-mount device from each of the frequency
ranges. The “CHANNEL” LEDs assigned to these devices light up.
When two NET 1 are daisy-chained, pressing the MODE button 
automatically determines the “master” NET 1. The “REMOTE” LED of the
“slave” NET 1 lights up and its MODE button is deactivated.
To determine the desired frequency range for the frequency scan, you first
have to select a rack-mount transmitter (IEM) belonging to the desired
frequency range as follows:
왘Press the corresponding channel button .
The green “CHANNEL” LEDs of the rack-mount transmitters (IEM) with
the same frequency range flash. The infrared interface is permanently
backlit in blue and the yellow “SCAN” LED 쐋flashes.
The RF signals of the rack-mount transmitters are muted. The display
backlighting changes from green to red.
Example:
The connection groups 1 to 4 of the NET 1 are occupied by transmitters (IEM).
The connection groups 6 to 10 are occupied by rack-mount receivers. After
pressing the MODE button , the green “CHANNEL“ LEDs for the first rack-
mount transmitter (connection group 1) and the first rack-mount receiver
(connection group 5) light up. The “CHANNEL“ LEDs of the other rack-
mount devices do not light up, i.e. they belong to the same frequency range.
After pressing the channel button , both the “CHANNEL“ LEDs 2 to 4 of
the monitoring system and the yellow “SCAN” LED 쐋flash.

channels as transmitters (IEM) from this frequency range are connected to
the NET 1.
왘Confirm your selection by pressing the SET button.
Transferring frequencies to the rack-mount transmitters (IEM)
The frequencies are transferred to the corresponding rack-mount
transmitters via the infrared interface.
The infrared interface of the receiver (IEM) is located in the battery
compartment.
왘For data transfer, open the cover of the portable receiver (IEM).
왘Place the receiver (IEM) in front of the infrared interface . The distance
between the infrared interface of the NET 1 and the infrared interface of
the receiver (IEM) must not exceed 10 cm.
Note:
Strong extraneous light may interfere with the data transfer via the
infrared interface. Therefore, position the receiver (IEM) so as to avoid
interference from extraneous light. The arrow in the diagram on the left
indicates the direction from which the IR radiation must impinge upon the
receiver (IEM).
The NET 1 assigns the frequencies of the selected channel bank to all rack-
mount transmitters (IEM) of the frequency range. If all frequencies have
been successfully transferred to the transmitters (IEM), the yellow “DATA
LINK” LED flashes slowly.
Note:
If you have connected more rack-mount transmitters (IEM) from one
frequency range than free channels are available in one channel bank,
switch off the surplus transmitters.
