The ew 300 IEM G2 system

With the Sennheiser evolution wireless in-ear monitoring system ew 300 IEM G2 (suitable for both stage and broadcast use), 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.

The evolution wireless in-ear monitoring system ew 300 IEM G2 is a highquality state-of-the-art RF transmission systems with a high level of operational reliability and ease of use. Transmitter and receiver permit wireless transmission with studio-quality sound. The excellent transmission reliability of the ew 300 IEM G2 system is based on the use of

yfurther optimized PLL synthesizer and microprocessor technology,

ythe HDX noise reduction system,

ythe pilot tone squelch control (during stereo operation),

yand the scan function for scanning the channel banks for free channels.

The channel bank system

The ew 300 IEM G2 system is available in five UHF frequency ranges with 1440 transmission/receiving frequencies per frequency range. Please note: Frequency usage is different for each country. Your Sennheiser agent will have all the necessary details on the available legal frequencies for your area.

Range A:	518 to 554 MHz
Range B:	626 to 662 MHz
Range C:	740 to 776 MHz
Range D:	786 to 822 MHz
Range E:	830 to 866 MHz

Transmitter and receiver have nine channel banks with up to 12 switchable channels each.

		channel 1		preset frequency
		channel 2		preset frequency
channel bank 1...8
		channel 12		preset frequency
		channel 1		freely selectable frequency
		channel 2		freely selectable frequency

channel bank U

channel 12		freely selectable frequency

The channel banks “1” to “8” have switchable channels that are factorypreset to a transmission/receiving frequency (see enclosed frequency table). These transmission/receiving frequencies cannot be changed but have been preset so that e.g. country-specific regulations on frequency usage are taken

42

into account. The channel bank “U” (user bank) has up to 12 switchable channels to store your selection out of 1440 transmission/receiving frequencies that are freely selectable within the preset frequency range.

An advantage of the factory-preset frequencies is that

ythe system is ready for immediate use after switch-on,

yseveral in-ear monitoring systems can be operated simultaneously on the preset channels without causing intermodulation interference.

Safety instructions

Never open electronic units! If units are opened by customers in breach of this instruction, the warranty becomes null and void.

Keep the units away from central heating radiators and electric heaters. Never expose them to direct sunlight.

Use the units in dry rooms only.

Use a damp cloth for cleaning the units. Do not use any cleansing agents or solvents.

Attention! High Volume!

This is a professional transmission system. 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 system 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 damage. The following are sure signs that you have been subjected to excessive noise for too long a time:

yYou can hear ringing or whistling sounds in your ears.

yYou have the impression (even for a short time only) that you can no longer hear high notes.

Indications and displays on the transmitter

Modulation display

The level display for audio signal “AF” shows the modulation of the transmitter.

When the transmitter’s audio input level is excessively high, the level display for audio signal “AF” shows full deflection.

When the transmitter is overmodulated frequently or for an extended period of time, the text “PEAK” (backlit in red) flashes in alternation with the standard display.

Button backlighting

During standby operation, the ON button is backlit in red. When the transmitter is switched on, the SET button and the / button are additionally backlit in green.

Indications and displays on the receiver

Operation and battery status indication

The red LED (LOW BAT/ON) provides information on the current operating state of the receiver:

Red LED lit up:	The receiver is switched on and the capacity of the
	batteries/accupack BA 2015 is sufficient.
Red LED flashing:	The batteries are/the accupack BA 2015 is going flat
	(LOW BAT)!

In addition, the 4-step battery status display on the display panel provides information on the remaining battery/accupack BA 2015 capacity:

3 segments:	capacity approx. 100 %

Mounting the transmitter feet

To ensure that the transmitter cannot slip on the surface on which it is placed, four self-adhesive soft rubber feet are supplied.

Ensure that the base of the transmitter is clean and free from grease before mounting the rubber feet.

Fix the rubber feet to the base of the transmitter by peeling of the safety paper and fitting them as shown in the digram on the left.

Attention!

Some furniture surfaces have been treated with varnish, polish or synthetics which might cause stains when they come into contact with other synthetics. Despite a thorough testing of the synthetics used by us, we cannot rule out the possibility of staining.

Connecting the antenna

The supplied telescopic antenna can be mounted quickly and easily to the rear of the transmitter and is suitable for all applications where – good

transmission conditions provided – a wireless transmission system is to be used without a large amount of installation work.

Connect the telescopic antenna to the BNC socket at the rear of the transmitter.

Pull the end cap to extend the telescopic antenna .

Use a remote antenna (available as an accessory) when the transmitter position is not the best antenna position for optimum transmission.

Connecting the mains unit

The transmitter is powered via a mains unit.

Pass the cable through the cable grip .

Insert the DC connector on the mains cable into the DC socket .

Connecting the amplifier/mixing console

Connect the amplifier/mixing console to the XLR-3F sockets (left and MONO) or (right).

Both balanced and unbalanced connection is possible (see “Connector assignment” on page 73).

Note:

Any unit that is only suitable for mono operation must be connected to XLR-3F socket . In this case, set the transmitter to mono operation via the menu.

Via the “Sensitiv” menu, adjust the transmitter’s input sensitivity (see “Adjusting the sensitivity (transmitter only)” on page 64).

Connecting the headphones/monitoring the audio signal

NeueAbbildung

To monitor the audio signal, connect headphones with a ¼” (6.3 mm) jack plug to the headphone output (PHONES) .

Attention! High volume!

Even short exposure to high volume levels will damage your hearing! Set the volume for the connected headphones to the minimum before putting the headphones on.

First, set the volume control ! to the lowest volume by turning it to the left as far as possible. Then gradually turn up the volume.

Volume up? – NO!

When people use headphones, they tend to choose a higher volume than with loudspeakers. Listening at high volume levels for long periods can lead to permanent hearing defects. Please protect your hearing, Sennheiser headphones have an excellent sound quality even at low volumes.
