Hazard warnings on the rear of the receiver
The label shown on the left is attached to the rear of the EM 9046.
The symbols on this label have the following meaning:
Presence of uninsulated dangerous voltage within the EM 9046's enclosure that may be of sufficient magnitude to constitute a risk of electric shock.
Never open the EM 9046 as there is a risk of electric shock. There are no user serviceable parts inside. Never attempt to change the modules of the EM 9046 yourself. Always refer repairs, servicing and the change of the modules to your authorized Sennheiser service partner.
Read and follow the safety and operating instructions contained in the instruction manual.
Risk of fire due to overloading
Do not overload wall outlets and extension cables as this may result in fire and electric shock.
Danger of hearing damage due to high volumes
This is a professional receiver. Commercial use is subject to the rules and regulations of the trade association responsible. Sennheiser, as the manufacturer, is therefore obliged to expressly point out possible health risks arising from use.
This receiver is capable of producing sound pressure levels exceeding 85 dB(A). 85 dB(A) is the sound pressure corresponding to the maximum permissible volume which is by law (in some countries) allowed to affect your hearing for the duration of a working day. It is used as a basis according to the specifications of industrial medicine. Higher volumes or longer durations can damage your hearing. At higher volumes, the duration must be shortened in order to prevent hearing damage. The following are sure signs that you have been subjected to excessive noise for too long a time:
- You can hear ringing or whistling sounds in your ears.
- You have the impression (even for a short time only) that you can no longer hear high notes.
Intended use
Intended use of the Digital 9000 system components includes:
- having read and understood this instruction manual, especially the chapter "Important safety instructions",
- using the products within the operating conditions and limitations described in this instruction manual.
"Improper use" means using the products other than as described in these instructions, or under operating conditions which differ from those described herein.
This instruction manual is also available at www.sennheiser.com.

The clock LED 📌 ⑥ provides information on the following states:
| clock LED Meaning | |
| lights up The receiver's digital audio output is synchronized with an external word clock signal. | |
| flashes | The "Word clock" menu item is set to "external", but the EM 9046 receiver cannot find an external word clock signal and generates its own word clock signal. The word clock rate of this signal corresponds to the last set or active word clock rate. As soon as an external word clock signal is present at the WORD CLOCK IN BNC socket 9, the digital audio output of the EM 9046 automatically synchronizes with it and the clock LED NR 6 lights up constantly. |

EM9046 ANT A ANT B RF OUT A RF OUT BDaisy chaining receivers
The EM 9046 receivers feature an integrated antenna splitter so that up to four receivers can be daisy chained. This allows you to use two antennas/antenna boosters for up to four receivers. In this case, all receivers have to use the same booster frequency range.
▶ Use GZL 9000 antenna cables to connect two antennas via antenna boosters to the RF IN N-type sockets 15 and 16 of the first receiver.
Connect the RF OUT N-type sockets of the first receiver to the RF IN N-type sockets of an additional receiver. To do so, use the RF patch cables from the EM 9046 CAB cable set.
▶ Repeat the previous steps for up to four receivers.
The length of the RF patch cables from the EM 9046 CAB cable set allows a distance of 1 height unit (HU) between two EM 9046 in a 19" rack.
If you want to pass on word clock signals between daisy chained receivers and/or if you want to connect daisy chained receivers in a network (see the following chapters):
Connect the receivers in the same order in which you connected the RF N-type sockets. Always connect the network sockets from LAN DOWN to LAN UP and word clock sockets from OUT to IN.

* If you have installed a MAN card in the first receiver of the daisy chain and if you use the card's word clock as the external master, the connection to the external word clock generator is no longer required (see next section).
** This diagram illustrates a convenient way of daisy chaining the receivers. Sennheiser recommends using an external switch to connect the receivers in a star topology (see "Connecting receivers in a network" on page 36).

text_image
EM9046 BNC (Word Clock in)Connecting external word clock signals
The EM 9046 receiver supports external word clock sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz and 96 kHz. If you have installed a MAN card, you can alternatively use the card's word clock as external word clock generator.
(This step is not required if you use the word clock signal of a built-in MAN card.)
Use a shielded 75 Ω coaxial BNC cable to connect the word clock output of an external word clock generator to the BNC socket ⑨ of the EM 9046.
Connect the BNC sockets of the receivers.
If you have daisy chained your receivers (see page 35):
Connect the BNC sockets of the receivers in the order shown on page 35.

For an overview of the states of the clock LED, refer to page 20.
Connecting receivers in a network
The EM 9046 has two network sockets LAN UP ③ and LAN DOWN ④, allowing you to connect additional EM 9046 or other network-compatible Sennheiser receivers in a network.
All receivers in the network can be controlled via the Wireless Systems Manager (WSM) software. In addition, interconnected receivers allow you to simultaneously headphone monitor the channels of all receivers and the stream arbitrary channels to an external audio player or to the WSM.
There are two ways to connect several EM 9046 in a network:
- Ethernet daisy chaining:

- You use both network sockets (LAN UP and LAN DOWN) of the receivers. This causes the receivers to act as a switch. You do not require an external switch.
- The Spanning Tree Protocol (STP) and/or the Rapid Spanning Tree Protocol, (RSTP) are used to detect and deactivate redundant paths in the local network. Redundant paths are caused by faulty cabling (unintentional cabling loops).
- STP and RSTP exchange configuration packets and, as a result, induce a higher network load. Individual switches in your local network can be set to a standby mode so that a loop-free network topology results. This makes your network faster and more efficient.
If a connection fails, STP and RSTP automatically attempt to reestablish the failed connection (e.g. by reactivating switches). This can cause network outages of up to 50 seconds.
Connect the first EM 9046 to a switch, PC or laptop. We recommend using a CAT5 Ethernet cable with crush-resistant Neutrik EtherCon connectors.
Connect the receivers to one another using the CAT5 Ethernet cables from the EM 9046 CAB cable set. Always connect the network sockets from LAN DOWN to LAN UP.
If you have daisy chained your receivers (see page 35):
Connect the network sockets of the receivers in the order shown on page 35.
-
Connecting the receivers in a star topology (recommended):
-
You only use the LAN UP network socket of the receivers. This deactivates STP and RSTP.
- You require an external switch.
- Your network uses a star topology
Connect all EM 9046 to a switch using the CAT5 Ethernet cables from the EM 9046 CAB cable set
Connect the switch to a computer or laptop. We recommend using a CAT5 Ethernet cable with crush-resistant Neutrik EtherCon connectors.

For information on headphone monitoring of channels, refer to page 84.
Preparing the A/AB/AD 9000 antennas and/or antenna boosters for use
Antennas and antenna boosters of the Digital 9000 series are available in two variants: A1–A8 and B1–B8.
Select the booster variant (A1–A8 or B1–B8) whose frequency range matches that of your transmitters:
| Booster variant A1-A8 | B1-B8630-798MHz | |||||||||||||||
| Booster frequency ranges | A1 | A2 | A3 | A4 | A5 | A6 | A7 | A8 | B1 | B2 | B3 | B4 | B5 | B6 | B7 | B8 |
| Bandwidth MHz | 470-494 | 494-518 | 510-534 | 534-558 | 550-574 | 574-598 | 590-614 | 614-638 | 630-654 | 654-678 | 670-694 | 694-718 | 710-734 | 734-758 | 750-774 | 774-798 |
| Transmitter | type A1-A4470-558 MHz | type A5-A8550-638 MHz | type B1-B4630-718 MHz | type B5-B8710-798 MHz | ||||||||||||
Use two A 9000 receiving antennas or two AD 9000 receiving antennas or two passive antennas together with AB 9000 antenna boosters:
Product name Type Radiation pattern
A 9000 active, intelligent omni-directional
AD 9000 active, intelligent directional
AB 9000 antenna booster depending on the passive antenna used
If both antenna boosters are connected or replaced, the EM 9046 automatically measures the cable attenuation between the antenna boosters and the antenna inputs and compensates for it. During the measurement, the channel status display displays "Calibrating" for each channel. If only one antenna booster is connected or replaced, the cable attenuation will not be measured. You can also manually initiate the compensation of the cable attenuation (see ""Cable attn" - Displaying the cable attenuation and automatically compensating for it" on page 64).
Positioning the receiving antennas

CAUTION
Material damage and personal injury due to tipping/dropping of the antennas!
If you do not protect the antennas against tipping/dropping, they can cause material damage and personal injury.
Use safety wires to protect the receiving antennas against tipping/dropping. The safety wires, rope terminations and coupling links must comply in their dimensioning and condition with the regulations and standards of the country in which they are used!
▶ Position the receiving antennas in the same room in which the transmission takes place! Maintain a minimum distance of 1 m between the two receiving antennas/antenna boosters and a minimum distance of 50 cm between the antennas/antenna boosters and metal objects (including reinforced concrete walls).
Connecting the receiving antennas/antenna boosters
▶ Use GZL 9000 antenna cables.
Sennheiser GZL 9000 antenna cables are available in lengths of 5 m, 10 m and 20 m.
A/AB/AD 9000:
Connect the RF out sockets ④ of the antennas/antenna boosters used to the N-type sockets RF IN A ⑮ and RF IN B ⑯ of your EM 9046.
AB 9000:
Connect the RF IN socket ⑥ of the two antenna boosters to one antenna each.
▶ Use short cables to keep the cable attenuation as low as possible.
Adjusting the receiving antennas/antenna boosters
The EM 9046 receiver controls the preselection of the booster frequency ranges. No further settings need to be made on the A/AB/AD 9000 antennas/antenna boosters.
You can also use the antennas/antenna boosters with other receivers if the following conditions are met:
▶ Use a receiver with booster supply voltage (e.g. EM 3732-II).
Use a cable whose length and attenuation match the amplification of 17 dB of the A/AD/AB 9000 antennas and antenna boosters.
▶ Use the "Filter" rotary switch ⑧ to manually set the booster frequency range (see table on page 39).

"Frequency scan" – Performing a frequency scan of all 8 frequency ranges
The main menu contains two menu items that allow you to perform a frequency scan:
-
First, use the "Frequency scan" menu item to find and activate a suitable booster frequency range.
-
Then use the "Range detail scan" menu item to assign frequency presets from the activated booster frequency range to the channels. Optionally, you can perform a new frequency scan of the activated booster frequency range.
You can then adjust the settings to be transferred to your transmitters and synchronize the transmitters and the receiver via infra-red.

text_image
Frequency scan freq scanDuring the frequency scan ("Frequency scan" menu item), the interference levels received by the antennas are recorded and displayed for the booster frequency ranges 1 to 8.
Before performing a frequency scan, carry out the following steps:
Switch off all transmitters that you want to wirelessly connect to the EM 9046.
Switch on all possible sources of interference (e.g. light sources, intercom links, video walls) and all other transmission links.
To perform a frequency scan:
▶ Call up the "Frequency scan" menu item.
If a frequency scan has already been performed, the last activated booster frequency range is highlighted in blue.
▶ Turn the jog dial ⑰ until the text "start scan" at the bottom margin of the screen is highlighted in blue:

bar
| Frequency Band | Start scan (dBm) | |---|---| | 630-654 | -100 | | 634-678 | -90 | | 670-694 | -80 | | 694-728 | -70 | | 728-750 | -60 | | 750-774 | -50 | | 774-798 | -40 | | 798 MHz | -30 | | Range | -50 to -90 dBm | | Noise Level Zone: HD | -100 to -90 dBm | | Noise Level Zone: HD/LR | -100 to -90 dBm | | Noise Level Zone: LR/TO | -100 to -90 dBm | | Noise Level Zone: LR | -100 to -90 dBm | | RF IN AID: Start scan | 0 |▶ Start the frequency scan by pressing the jog dial ⑰. Please note: All audio outputs will be muted!
The duration of the frequency scan depends on the number of the built-in EM 9046 DRX receiver modules. The more modules you use, the faster the frequency scan is performed.
The interference levels received by the antennas are recorded and displayed. The interference levels are divided into four interference zones: "HD", "HD/LR", "LR/HD" and "LR". The lower the zone, the lower the received interference level.
In addition, the number of unused frequency presets is displayed per booster frequency range and per interference zone. The number of unused frequency presets depends on the number, the height and the frequency of the received interference levels.

The selection of a suitable booster frequency range depends on several factors:
- Required number of transmission links
- Sufficient number of unused frequency presets
- Sufficient number of transmitters of the correct type (in this example, transmitters of type B1–B4 or B5–B8, see page 39)
- Recommended transmission mode "HD" or "LR":
"HD (High Definition)": Transmission of an audio signal without audio data compression. As a result, the audio signal remains pure and unadulterated. In "HD" transmission mode, the range can be restricted compared to "LR" transmission mode.
"LR (Long Range)": Transmission of an audio signal whose bit rate is reduced – before transmission – by an audio data compression technique (SeDAC, Sennheiser Digital Audio Codec). This compression technique provides excellent audio quality and a large transmission range. The sensitivity to interference is reduced compared to "HD" transmission mode.
| Interference levels of antenna A/B in interference zone | [TYSC] "HD" | [KDZZ] "HD/LR" | [YSAW] "LR/HD" | [4X8C] |
![]() | ![]() | ![]() | ![]() | ![]() |
* Transmission mode can be used with a restricted range
** It might be that the transmission mode can only be used with a severely restricted range
Let us assume that you want to set up 8 transmission links and transmit in "HD" transmission mode with the maximum possible transmission range.
Have a look at interference zone "HD" (see also above diagram): All booster frequency ranges except for B6 provide a sufficient number of unused frequency presets.
| Booster frequency ranges | B1 B2 B3 B4 B5 B6 B7 B8 |
| Number of unused frequency presets in interference zone “HD” | 40 35 27 36 29 6 26 31 |
| Can the booster frequency range be used? | √ √ √ √ √ - √ √ |
Example 1: 8 transmitters of type B1–B4
Let us assume that you have 8 transmitters of type B1-B4:
| Is there a sufficient number of transmitters of the correct type? | √ | √ | √ | √ | ---- |
You can use any of the booster frequency ranges B1–B4 but you should select the booster frequency range with the highest number of unused frequency presets: B1.
Example 2: 6 transmitters of type B1–B4, 8 transmitters of type B5–B8
Let us assume that you have only 6 transmitters of type B1–B4 but 8 transmitters of type B5–B8.
Is there a sufficient number of transmitters of the correct type?

The number of transmitters is sufficient but the booster frequency range B6 does not provide a sufficient number of unused frequency presets in interference zone "HD". You could therefore use the booster frequency ranges B5, B7 or B8 but you should select the booster frequency range with the highest number of unused frequency presets: B8.
In this example, there was a sufficient number of unused frequency presets available for interference zone "HD", allowing you to adjust the "HD" transmission mode for all channels. If this is not the case, you can, in a later step, also adjust the "LR" transmission mode for individual channels.
To activate the booster frequency range:
▶ Select a suitable booster frequency range by turning the jog dial ⑰. The frequency range is highlighted in blue.
▶ Activate the booster frequency range by pressing the jog dial ⑰. "active" appears below the activated booster frequency range (see above diagram). You can still change your selection by choosing a different booster frequency range and then pressing the jog dial ⑰ again.
▶ Finish the frequency scan and store the previously activated range by pressing the button ⑯.
▶ Assign frequency presets to the channels as described in the next section.
"Range detail scan" – performing an optional frequency scan of the active frequency range and assigning frequency presets to the channels
▶ Call up the "Range detail scan" menu item.
The activated booster frequency scan and the result of the last frequency scan ("Frequency scan" or Range detail scan") are displayed. "Select channel or press SET to scan" appears in the menu selection.

Performing a frequency scan
To perform a new frequency scan of the activated booster frequency range (optional):
▶ Start the frequency scan by pressing the jog dial ⑰. Please note: All audio outputs will be muted!
Assigning frequency presets to the channels
To assign frequency presets to the channels:
Select one of the channels 1–8 by pressing its channel button 23. A mark with a flag and a channel number appears.

| Frequency (MHz) | Value (dBm) | | --------------- | ----------- | | 774,000 | -50 | | 778,000 | -90 | | 782,000 | -100 | | 786,000 | -100 | | 790,000 | -100 | | 794,000 | -100 | | 798,000 | -100 |Automatically selecting a frequency preset
There are three ways to assign a frequency preset or a frequency to a channel:
- You can automatically select the frequency preset with the lowest interference level. This is the quickest and most convenient way of assigning a frequency to a channel.
- You can manually select a frequency preset.
- You can manually set an arbitrary frequency.
To automatically select the frequency preset with the lowest interference level, proceed as follows:
▶ Turn the jog dial until "auto" appears.

text_image
Preset auto Freq 787 . 400 MHz Range: 774 - 798 MHz detail scanAfter the frequency scan, the receiver automatically creates an ordered list containing the 32 frequency presets with the lowest interference levels. The frequency presets in the list are ordered according to increasing interference levels.
The first frequency level in the list has the lowest interference levels. The mark automatically snaps into position on this frequency preset and the corresponding frequency value is displayed.
The numeric values of the measured interference levels for antenna A and antenna B are additionally displayed at the top margin of the screen.
▶ Press the jog dial.
The selected channel is assigned the frequency preset with the lowest interference level.

Please note that the frequency presets are assigned in the order of increasing interference levels:
- The first channel is assigned the frequency preset with the lowest interference levels.
- The second channel is assigned the frequency preset with the next higher interference levels.
- The last channel is assigned the frequency preset with the highest interference levels.
You should therefore use the first channel for the most important transmission link in your multi-channel system.
Each new frequency scan creates a new frequency preset list.
Manually selecting a frequency preset
To manually select an unused frequency preset, proceed as follows:
▶ Move the mark by turning the jog dial ⑰.
The mark snaps into position on the frequency presets.
▶ Select a frequency preset.
The numeric values of the measured interference levels for antenna A and antenna B are additionally displayed at the top margin of the screen.
The interference levels of both antennas should be within or below the interference zone that is required or useful for this channel (see page 56 and 58) and should be as low as possible.
Manually setting a frequency
If you do not want to use a frequency preset but you want to set a frequency yourself, proceed as follows:
▶ Press the jog dial.
Each time you press the jog dial, you switch between
- the "Preset" settings,
– the frequency setting in MHz steps and
– the frequency setting in kHz steps.
▶ First set the frequency in MHz steps by turning the jog dial. Press the jog dial to confirm your setting.
▶ First set the frequency in kHz steps by turning the jog dial. Press the jog dial to confirm your setting.
Maintain a frequency spacing of at least 600 kHz in order to avoid intermodulation interference.
Please observe the flag position of the selected frequency preset: If the flag appears on the left or right margin and is pointing outwards, the frequency is outside the selected booster frequency range.
Assigning frequencies to the remaining channels
▶ Select the next channel 1 ... 8 by pressing the channel 1–8 button ^23 and proceed as described above.
All frequencies assigned to a channel are displayed by means of a mark with a flag and a channel number. If you have daisy chained several receivers (see “Daisy chaining receivers” on page 35), their frequency settings are also displayed in contrasting colors. This allows an overview over up to 32 channels.
Once you have selected a frequency preset for all desired channels, press the button 16.
Your settings are stored and the receiver switches to the main menu "System setup".
To switch to the main menu without storing your settings:
▶ Press the esc button ②.
To configure your transmitters:
Change to the "ch" operating mode on the EM 9046 (see page 76).
▶ Select one of the channels for which you have stored frequency presets.
▶ Call up the extended menu "Transmitter setup" and then call up the "RF mode" menu item.
Adjust the transmission mode ("HD" or "LR") depending on the interference zone of the channel (see also table on page 59).
Configure your channels as described from page 76 onwards.
▶ Synchronize the transmitters and the receiver as described on page 77.
▶ Repeat for the other channels.
▶ Perform a walk test to check the reliability of your transmission links (see page 80).
Change the transmission mode for the channels with reception problems and then synchronize the transmitters and the receiver again.
If the reception problems persist, select a different booster frequency range.

Using the SK 9000

Before using your bodypack transmitter, ask the relevant wireless regulatory authority for the exact frequency allocations and apply for an individual license if necessary.
The supplied supplement "Framework requirements and restrictions on frequency usage in Europe" provides an overview of the different European framework requirements and restrictions on frequency usage. If there is no entry in the supplement, ask the relevant wireless regulatory authority for the current rules governing frequency usage.
Switching the SK 9000 on/off

When the SK 9000 is switched on for the first time, it contains the first frequency preset of the transmitter frequency range (e.g. A1.1:470.200 MHz). Via the "ch" menu of the EM 9046 receiver, set the desired frequency preset and adjust the settings of other menu items and then synchronize the transmitter and the receiver (see page 77). In doing so, all frequency presets of the transmitter frequency range will be transferred to the SK 9000.
We recommend you to always adjust the transmitter settings via the EM 9046 receiver and then to synchronize the transmitter and the receiver.
