2 Important safety instructions

Important safety instructions

• Read this instruction manual.

• Keep this instruction manual. Always include this instruction manual when passing the device on to third parties.

• Heed all warnings and follow all instructions.

• Clean the device only with a slightly damp cloth.

• Do not place the device near any heat sources such as radiators, stoves, or other devices (including amplifiers) that produce heat.

• Only use attachments/accessories specified by Sennheiser. • When replacement parts are required, only use replacement parts spec ified by Sennheiser or those having the same characteristics as the orig inal part. Unauthorized substitutions may result in fire, electric shock, or other hazards.

• WARNING: To reduce the risk of short circuits, do not use the device near water and do not expose it to rain or moisture.

Intended use

Intended use of the SKM 2000 radio microphone includes: • having read these instructions especially the chapter “Important safety instructions”, • using the device within the operating conditions and limitations described in this instruction manual.

“Improper use” means using the device other than as described in these instructions, or under operating conditions which differ from those described herein.

The SKM 2000 radio microphone

The SKM 2000 radio microphone

This radio microphone is part of the 2000 series. With this series, Sennheiser offers high-quality state-of-the-art RF transmission systems with a high level of operational reliability and ease of use. Transmitters and receivers permit wireless transmission with studio-quality sound.

Features of the 2000 series: • Optimized PLL synthesizer and microprocessor technology • HDX noise reduction system • Pilot tone squelch control • True diversity technology • Switching bandwidth of up to 75 MHz • Increased immunity to intermodulation and interferences in multi channel operation

Areas of application

The radio microphone can be combined with the EM 2000 or EM 2050 rack mount receiver. The receivers are available in the same UHF frequency ranges and are equipped with the same frequency bank system with factory-preset frequencies. An advantage of the factory-preset frequen cies is that • a transmission system is ready for immediate use after switch-on, • several transmission systems can be operated simultaneously on the preset frequencies without causing intermodulation interference.

Synchronizing the radio microphone with a receiver

Synchronizing the radio microphone with a receiver

When synchronizing the radio microphone with a receiver, please observe the following: Only use a radio microphone and a receiver from the same frequency range (see the type plate on the radio microphone and the receiver).

Make sure that the desired frequencies are listed in the enclosed frequency information sheet.

Make sure that the desired frequencies are approved and legal in your country and, if necessary, apply for an operating license.

Synchronizing the radio microphone with the receiver – individual operation

Upon delivery, the radio microphone and the receiver are synchronized with each other. However, if you cannot establish a transmission link between radio microphone and receiver, you have to synchronize the channels of the devices.

For information on automatic synchronization of the radio microphone with the receiver (individual operation), refer to the instruction manual of the receiver. This information is marked with the icon.

Alternatively, you can set the channel on the radio microphone manually: Make sure that you set the radio microphone to the same frequency bank and the same channel as the receiver.

If you still cannot establish a transmission link, refer to the chapter „If a problem occurs ...“ auf Seite 21.

Synchronizing radio microphones with receivers – multi-channel operation

Combined with 2000 series receivers, 2000 series radio microphones can form transmission links that can be used in multi-channel systems. In order to ensure an intermodulation-free transmission, use the same frequency bank for all transmission links.

For information on automatic synchronization of radio microphones with receivers (multi-channel operation), refer to the instruction manual of your receiver. For more information on multi-channel operation, visit the corresponding product page at www.sennheiser.com.
