Always include this instruction manual when passing the product on to third parties.•Heed all warnings and follow all instructions.•Use only a cloth for cleaning the product.•Do not place the product near any heat sources such as radiators, stoves, or other devices (including amplifiers) that produce heat.•Only use attachments/accessories specified by Sennheiser.•Refer all servicing to qualified service personnel.Servicing is required if the product has been damaged in any way, liquid has been spilled, objects have fallen inside, the product has been exposed to rain or moisture, does not operate properly or has been dropped.•WARNING: To reduce the risk of short circuits, do not use the product near water and do not expose it to rain or moisture.Intended useIntended use of the SK 2000 bodypack transmitter includes:•having read this instruction manual, especially the chapter “Important safety instructions”,•using the product within the operating conditions and limitations described in this instruction manual.“Improper use” means using the product other than as described in these instructions, or under operating conditions which differ from those described herein.2The SK 2000 bodypack transmitterThe SK 2000 bodypack transmitterThis bodypack transmitter 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 operationAreas of applicationThe bodypack transmitter can be combined with the EM2000 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 frequencies 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.3The SK 2000 bodypack transmitterOverview of the microphones and instrument cables:The frequency bank systemThe bodypack transmitter is available in 6 UHF frequency ranges with up to 3,000 transmission frequencies per frequency range:Each frequency range (Aw–Ew, Gw, GBw) offers 26 frequency banks with up to 64 channels each:4Delivery includes Each of the channels in the frequency banks “1” to “20” has been factory-preset to a fixed frequency (frequency preset). The factory-preset frequencies within one frequency bank are intermodulation-free. These frequencies cannot be changed.For an overview of the frequency presets, please refer to the supplied frequency information sheet. Updated versions of the frequency informa-tion sheet can be downloaded from the corresponding product page on our website at .The frequency banks “U1” to “U6” allow you to freely select and store transmission frequencies. It might be that these transmission frequencies are not intermodulation-free.Delivery includesThe packaging contains the following items:1 SK 2000 bodypack transmitter2 AA size batteries, 1.5 V1 instruction manual1 frequency information sheet1 supplement “Framework requirements and restrictions on the use of radio microphones”5Product overviewProduct overviewOverview of the SK 2000 bodypack transmitter³Microphone/instrument input (MIC/LINE), 3-pole special audiosocket, lockable·MUTE switch»Antenna¿Operation and battery status indicator, red LED:lit = ONflashing = LOW BATT´Audio overmodulation indicator, yellow LED:lit = AF PEAK ²Charging contacts¶SET buttonºUP/DOWN button ̆/̄¾Battery compartmentµBattery compartment cover (metal)¸Battery compartment catches ¹Infra-red interfaceƸON/OFF button(serves as the ESC (cancel) key in the operating menu)ƹDisplay panel, backlit in orange6Product overviewOverview of the displaysAfter switch-on, the bodypack transmitter displays the standard display “Frequency/Name”.
