The NET 1 network system The NET 1 allows you to control and monitor wireless Sennheiser multichannel systems. Its main feature is frequency management, significantly simplifying the set up of complex wireless systems. The NET 1 is a suitable tool for configuring your system: It scans the channel banks, automatically assigns the frequencies to the connected receivers and wirelessly synchronizes the transmitters. You can connect up to 10 receivers to one NET 1.

Putting the NET 1 into operation When putting the NET 1 into operation for the first time or when changing system components, operate the NET 1 with a PC. Setting up the NET 1 Strong extraneous light may interfere with the transfer of the transmission frequencies via the infra-red interface. Therefore, position the NET 1 so that any possible interference caused by extraneous light is avoided. Rack-mounting the NET 1 Note: All NET 1 are delivered with the rack-mounting kit pre-assembled.
Fitting the device feet (table top device only) To ensure that the NET 1 cannot slip on the surface on which it is placed when using it as a table top, fix the supplied four self-adhesive soft rubber feet to the base of the NET 1. 왘 Ensure that the base of the NET 1 is clean and free from grease before fitting the rubber feet. 왘 Fix the rubber feet to the base of the NET 1 by peeling off the backing paper and fitting them as shown in the diagram on the left.
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. Connecting the EM 3532 twin receiver 왘 Connect the EM 3532 twin receiver via its right-hand data interface DATA IN/OUT to the sub-D socket on the NET 1 as shown in the diagram below.
Connecting the NET 1 to a PC The following applications with up to five NET 1 require the connection of a PC : y Systems with up to 50 evolution wireless G2 receivers y Systems with up to 25 EM 3532 twin receivers y Mixed systems consisting of evolution wireless G2 receivers and EM 3532 twin receivers The MAC addresses of the NET 1 are indicated on the type plate (refer to the instructions for use of the “Wireless Systems Manager” software).
Switching on the receivers 왘 Switch on the receivers as described in the instructions for use of the receivers. Switching on the NET 1 왘 Press the ON/OFF switch to switch on the NET 1. After switch-on, the green “READY” LED flashes, indicating that the NET 1 is being initialized. As soon as the NET 1 is ready for operation, the “READY” LED lights up permanently and the infra-red interface is permanently backlit in blue.
Updating the firmware The NET 1 is compatible with previously released Sennheiser wireless systems of the evolution wireless G2 series or the 3000/5000 series – provided they have the latest firmware installed. These receivers or transmitters are marked with “NET” on their type plate or can be identified via the additional menu item “Software-Revision” or “SW REV” in the operating menu.
Problems that may occur when putting the NET 1 into operation Problem Possible cause Possible solution The green “READY” LED has gone off. The power cord is not connected correctly. Check if the power cord is connected correctly. The NET 1 is switched off. Switch on the NET 1. The green “CHANNEL” LED The cable of the corresponding receiver Check if the cable is connected does not light up, even though a is not connected correctly. correctly. receiver is connected.
Operation with systems of the evolution wireless G2 series When using receivers of the evolution wireless G2 series, there are three operating modes: 1. “Single Device” operating mode: one NET 1 with up to 10 receivers 2. “Master/Slave” operating mode: two NET 1 with up to 20 receivers 3. “Remote” operating mode: up to five NET 1 connected to a PC with up to 50 receivers. The connected receivers may well have different frequency ranges.
Selecting a channel bank and transferring the scan result to the receivers The receiver that has performed the frequency preset scan will then display (for each channel bank) the number of free frequencies (channels). The “CHANNEL” LEDs of all receivers of this frequency range flash slowly. Disturbed or occupied frequencies are blocked for frequency assignment.
왘 Place the transmitter in front of the infra-red interface . The distance between the infra-red interface of the NET 1 and the infra-red interface of the transmitter should be approx. 10 cm. 왘 On the NET 1, press the channel button you want to transfer. of the receiver whose frequency The green “CHANNEL” LED of the selected receiver flashes rapidly, indicating that data is being transferred to the transmitter.
"Master/Slave” operating mode 왘 Connect two NET 1 as described under “Connecting two NET 1” on page 13. You can connect up to 20 receivers to two NET 1. They may even belong to different frequency ranges. However, the number of receivers from one frequency range may not exceed the number of channels in one channel bank of the receivers.
Operation with 3000/5000 series systems Transferring frequencies to receivers when a PC is connected For information on how to transfer frequencies to an EM 3532 twin receiver when a PC is connected, please refer to the instructions for use of the “Wireless Systems Manager” software. For information on how to perform a frequency preset scan when a PC is connected, please also refer to the instructions for use of the “Wireless Systems Manager” software.
Transferring frequencies to the transmitters The infra-red interface of the SK 5212 bodypack transmitter is located under the display in the black frame. The infra-red interfaces of the SKM 5200 handheld transmitters and the SKP 3000 plug-on transmitters are is located under the display’s faceplate. Note: SK 5212 SKP 3000 Strong extraneous light may interfere with the transfer of the transmission frequencies via the infra-red interface.
Mixed operation of evolution wireless G2 series systems and 3000/5000 series systems For information on mixed operation of evolution wireless G2 series systems and 3000/5000 series systems, please refer to the instructions for use of the “Wireless Systems Manager” software.
Problems that may occur during operation Problem Possible cause Possible solution NET 1 has assigned the same frequency to several evolution wireless G2 receivers You have connected more receivers from one frequency range than there are free channels in the channel bank. Only connect as many receivers from one frequency range as there are free channels in the channel bank and restart the frequency preset scan.
If a problem occurs ... You will find tables describing possible problems y at the end of the chapter “Putting the NET 1 into operation” on page 11 y at the end of the description of the different operating modes on page 25 If a problem occurs that is not listed in the tables or if the problems cannot be solved with the proposed solutions, please contact your local Sennheiser agent for assistance.
