Important safety instructions

Danger due to high volumes

This is a professional transmitter. 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 transmitter is capable of producing sound pressure 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 SR 300 IEM transmitter includes:

• having read this instruction manual 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 evolution wireless series ew 300 IEM G3

This transmitter is part of the evolution wireless series generation 3 (ew G3). 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 are designed for monitoring applications and permit wireless transmission with studio-quality sound.

The SR 300 IEM rack-mount transmitter

With the 2-channel/stereo monitoring system of the SR 300 IEM transmitter, musicians, video and sound amateurs, reporters/broadcasters, etc. can directly monitor the received sound signals without troublesome cables or monitor speakers being required. In addition, the system can also be used for any application where talkback signals are to be transmitted.

Features of the SR 300 IEM G3 transmitter:

• Optimized PLL synthesizer and microprocessor technology

• HDX noise reduction system

• Pilot tone squelch control

• True diversity technology

• Switching bandwidth of 42 MHz

• Safe configuration of a multi-channel system using the WSM

The frequency bank system

The transmitter is available in 6 UHF frequency ranges with 1,680 transmission frequencies per frequency range:

516 – 558 566 – 608 626 – 668 734 – 776 780 – 822 823 – 865

Delivery includes

Each frequency range (A–E, G) offers 26 frequency banks with up to 16 channels each:

Kanal 1 – Frequenz-Preset

Kanal 2 – Frequenz-Preset

Kanalbank 1... 20

Kanal 16 – Frequenz-Preset

Kanal 1 – frei wählbare Frequenz

Kanal 2 – frei wählbare Frequenz

Kanalbank U1 ... U6

Kanal 16 – frei wählbare Frequenz

Each of the channels in the frequency banks “1” to “20” has been factory-preset to a fixed transmission 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 information sheet can be downloaded from the corresponding product page on our website at www.sennheiser.com.

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 (see page 20).

Delivery includes

1 SR 300 IEM G3 rack-mount transmitter

1 NT 2-3 mains unit with one country adapter

1 rod antenna

1 GA 3 rack adapter

1 instruction manual

Putting the transmitter into operation

Preparing the transmitter for use

When using more than one transmitter, we recommend connecting remote antennas and, if necessary, using Sennheiser antenna accessories. Fore more information, visit the ew G3 product page at www.sennheiser.com.

Setting up the transmitter on a flat surface

Place the transmitter on a flat, horizontal surface. Please note that the device feet can leave stains on delicate surfaces.

The rack mount “ears” are designed to help protect the operating elements from damage or deformation, e.g. if the transmitter is dropped. Therefore, fasten the rack mount “ears”, even if you do not want to rack mount your transmitter.
