settings.
►
Setting the frequency automatically (AUTO SCAN)
Performs an automatic frequency scan of your area. This en-
ables you to easily find and assign free radio frequencies.
▷ Switch off all transmitters before you perform the scan. If
transmitters are still switched on, they are detected as un-
available frequencies and the frequencies that are actually
available cannot then be used.
▷
▷
Press the SET/SCAN button for approx. 3 seconds.

►
▷ Press the SET/SCAN button to accept the displayed chan-
nel.
If you have set a new frequency, you must still syn-
chronize the receiver with the transmitter to es-
tablish the radio link (see „Establishing a radio link
| Synchronizing the receiver and transmitter“).
Setting the frequency manually
▷ Press the SET/SCAN button.

Adjusting the volume of the audio outputs
Use the VOL+/VOL- buttons to set the level of the audio signal
coming from the receiver’s audio outputs (Balanced/Unbal-
anced). This audio signal can be output to a mixing console or
an amplifier, for example.
▷ Press the VOL+/VOL- buttons to adjust the volume.
►
▷ Make sure that the signal in the next device in the signal
chain (e.g. mixing console, power amplifier, guitar amplifi-
er, etc.) is not overdriven.

Setting options on the rear of the device
Selecting the signal type (Mic/Line)
▷ Set the Line/Mic switch to the desired position.
• Line: when using instruments or other line sources with
the SK-XSW bodypack transmitter
• Mic: when using the SKM-XSW handheld transmitter or a
microphone with the SK-XSW bodypack transmitter
Setting the squelch
The squelch function can be used to suppress disturbing noise
during transmission, such as hiss. If the signal level is below
the squelch threshold, the signal is muted.
If the squelch threshold is set very high, this will shorten the
radio range.
▷ Turn the control knob to the left or right to adjust the
squelch.
EM-XSW 1 rack receiver

Configuring a multi-channel system
Please note when creating multi-channel systems:
Only the factory-preset transmission frequencies within one
frequency bank are intermodulation-free.
▷ Set the same channel bank for all receivers.
▷ Assign one channel from this channel bank to each receiv-
er.
We recommend using the AUTO SCAN function, as this is the
most reliable way to identify free frequencies (see „Setting the
frequency automatically (AUTO SCAN)“).
If you know free frequencies in your area, you can also set the
frequency manually (see „Setting the frequency manually“).

tablish the radio link (see „Establishing a radio link
| Synchronizing the receiver and transmitter“).

Adjusting the volume of the audio outputs
Use the VOL+/VOL- buttons to set the level of the audio signal
coming from the receiver’s audio outputs (Balanced/Unbal-
anced). This audio signal can be output to a mixing console or
an amplifier, for example.
▷ Press the VOL+/VOL- buttons to adjust the volume.
►
▷ Make sure that the signal in the next device in the signal
chain (e.g. mixing console, power amplifier, guitar amplifi-
er, etc.) is not overdriven.

the two channels.
• Line: when using instruments or other line sources with
the SK-XSW bodypack transmitter
• Mic: when using the SKM-XSW handheld transmitter or a
microphone with the SK-XSW bodypack transmitter
Setting the squelch
The squelch function can be used to suppress disturbing noise
during transmission, such as hiss. If the signal level is below
the squelch threshold, the signal is muted.
If the squelch threshold is set very high, this will shorten the
radio range.
▷ Turn the control knob to the left or right to adjust the
squelch.

Configuring a multi-channel system
Please note when creating multi-channel systems:
Only the factory-preset transmission frequencies within one
frequency bank are intermodulation-free.
▷ Set the same channel bank for all receivers.
▷ Assign one channel from this channel bank to each receiv-
er.
We recommend using the AUTO SCAN function, as this is the
most reliable way to identify free frequencies (see „Setting the
frequency automatically (AUTO SCAN)“).
If you know free frequencies in your area, you can also set the
frequency manually (see „Setting the frequency manually“).

relief.
▷ Insert the plug of the power supply unit into the Power
socket on the receiver.
▷ Slide the supplied country adapter onto the power supply
unit.
▷ Plug the power supply unit into the wall socket.
To completely disconnect the receiver from the power supply
system:
▷ Unplug the power supply unit from the wall socket.
▷ Unplug the power supply unit from the Power socket on the
receiver.

Installing receivers in a rack
CAUTION
Rack mounting poses risks
When installing the device in a closed 19" rack or multi-rack
assembly, please consider that, during operation, the ambient
temperature, the mechanical load and the electrical potentials
will be different from those of devices which are not mounted
into a rack.
▷ Make sure that the ambient temperature within the rack
does not exceed the permissible temperature limit stated
in the specifications. See „SPECIFICATIONS“.
▷ Ensure sufficient ventilation; if necessary, provide addi-
tional ventilation.
▷ Make sure that the mechanical load of the rack is even.
▷ When connecting to the power supply system, observe the
information indicated on the type plate. Avoid overloading
the circuits. If necessary, provide overcurrent protection.
▷ When mounting in a rack, please note that intrinsically
harmless leakage currents of the individual power supply
units may accumulate, thereby exceeding the permissible
limit value. As a remedy, ground the rack via an additional
ground connection.
To mount the receiver in a rack, you will need the GA 1-XSW 2
rack mount kit (see „Accessories“).

Mounting a single receiver in a rack
▷ Connect the mounting brackets to the sides of the receiver
as shown in the figure.
►
▷ Attach the front panel as shown in the figure.
▷ If desired, attach the antennas to the front panel as shown
in the figure.
This requires the optional GA 2-XSW 2 antenna front
mount kit (see „Accessories“).
►

Mounting two receivers side by side in a rack
▷ Place both receivers upside down and side by side on an

www.sennheiser.com/sifa
To establish a radio link between the transmitter and receiver,
we recommend the following procedure.
To successfully pair a receiver and a transmitter, both
devices must have the same frequency range.
Step 1: Set a free frequency on the receiver
We recommend using the AUTO SCAN function, as this is the
most reliable way to identify free frequencies (EM-XSW 1:
„Setting the frequency automatically (AUTO SCAN)“ | EM-
XSW 1 DUAL: „Setting the frequency automatically (AUTO
SCAN)“ | EM-XSW 2: „SCAN menu item“).
If you know free frequencies in your area, you can also set the
frequency manually (EM-XSW 1: „Setting the frequency manu-
ally“ | EM-XSW 1 DUAL: „Setting the frequency manually“ |
EM-XSW 2: „PRESET menu item“ or „TUNE menu item“).
Step 2: Synchronize the receiver and transmitter
▷ Press and hold the SYNC button on the transmitter.
The LED flashes alternately red and green.
▷ While the LED is flashing, short-press the SYNC button on
the receiver.
The transmitter and receiver are synchronized and the con-
nection is established.

▷ Note the special cleaning instructions below for the follow-
ing products.
Cleaning the sound inlet basket of the microphone
module
▷ Unscrew the top sound inlet basket from the microphone
module by turning it counterclockwise.
▷ Remove the foam insert.
You can clean the sound inlet basket in two ways:
• Use a slightly damp cloth to clean the top sound inlet basket
from the inside and outside.
• Use a brush and rinse with clean water.
▷ If necessary, clean the foam insert with a mild detergent or
replace the foam insert.
▷ Dry the top sound inlet basket and foam insert.
▷ Reinsert the foam insert.
▷ Screw the sound inlet basket back onto the microphone
module.
