Important safety instructions

Danger due to high volumes

This product is also intended for professional use. Commercial use is subject to the safety-atwork regulations. Sennheiser, as the manufacturer, is therefore obliged to expressly point out possible health risks arising from use.

This product 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 G3 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.

With the SR 300 IEM G3 2-channel/stereo monitoring 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, it 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

•Stereo/mono selection

• HDX noise reduction system

• Switching bandwidth of 42 MHz

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

• Easy setup of a multi-channel system using the Easy Setup Sync function

The frequency bank system

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

Range A:

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

Range G:

Delivery includes

Frequency bank 1... 20

Frequency bank U1 ... U6

Channel 16 – frequency preset

Channel 1 – frequency preset

Channel 2 – frequency preset

Channel 16 – freely selectable frequency

Channel 1 – freely selectable frequency

Channel 2 – freely selectable frequency

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

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 22).
