Safety Instructions

Please read these operating instructions carefully before using the product. They contain important information for the correct use of your product. Please keep them for future reference.
The wireless microphone systems of the E series consist of dynamic hand-held microphones with integrated transmitter which serve for wireless signal transmission to the receiving unit. The transmission range is approx. 60 m and depends on the local conditions. The system is available with 2 or 4 channels and up to 12 different transmission frequencies. Due to the color code it can easily be recognized which microphone operates with the respective receiver. Matching pocket transmitters are available as accessories.
These products are intended for use in the EU. The operation is license-free in Germany but is subject to restrictions in certain areas (status as of 2020): 518-534 MHz: AT, BE, LV, LT, RO, SE, GB, MT 823-832 MHz: AT, CZ, LT, LV, SK, RO, GB Prior to use, make sure that the desired frequencies are approved and legal in your country.

Setup and Operation

OMNITRONIC E2 Wireless Microphone System - Figure 5

4.1 Placing the receiver

Place the receiver on an even surface and connect the antennas provided to the antenna jacks. Put the antennas upright in a V-shaped position. Please note that the antennas provided are suitable for use in good reception conditions. If more than one receiver is to be used, it may be better to use remote antennas and, if necessary, an antenna splitter.
For 19″ rack installation (483 mm) screw on the two mounting brackets provided at the left and right sides of the housing. For rack mounting, the rod antennas can be attached to the front panel.

Notes

In order to ensure sufficient cooling of the unit, air must always be able to flow freely through all air vents.
Place the receiver at least 1 meter above the ground and not too close to lateral walls.
Avoid sources of interference such as metal surfaces or electronic devices (e.g. computer, CD player).
Ideally, position the receiving antennas at the height of the transmitter. When using multiple systems, do not allow antennas to cross or touch each other.
For optimum reception, keep the transmitter at least 1 meter away from the receiver and avoid obstacles.

4.2 Connecting the receiver

Connect the receiver to the subsequent unit:
• The balanced XLR outputs of the individual channel outputs can be connected to a microphone input each of a mixer.
• Use the unbalanced 6.3 mm jack “MIX OUT” for the master signal of all receiving channels for connection to a microphone input or a highly sensitive line input via the connection cable provided.
Finally, connect the power adapter to the power input of the receiver and the mains plug to a mains socket. Pass the cable through the cable grip. Use the receiver only with the supplied power adapter. Always disconnect the mains connector when you wish to change connections, move the unit to a different place or if it is not used for a longer period.

4.3 Hand-held microphone and pocket transmitter

For operation, the hand-held microphone and the pocket transmitter require two 1.5 V AA batteries each. To access the battery compartment unscrew the lower part of the microphone and unfold the locking part. In case of the pocket transmitter, fold up the front cover. Insert two batteries as indicated in the battery compartment.
With new batteries, the devices can be operated for approx. 10 hours. If the power indicator does not light up after switching on or if it starts flashing, the batteries are exhausted and have to be replaced. Ifthe devices are not used for a longer period, please remove the batteries to prevent damage in case ofbattery leakage.
Attach the pocket transmitter with the belt clip to your clothing or strap on your instrument. Connect the lavalier or headset microphone to the microphone input. The volume level of the pocket transmitter can be adjusted by changing the sensitivity with the gain control.
The pocket transmitter’s volume level can be adjusted by changing the sensitivity with the gain control in the battery compartment. Use a small screwdriver to turn the selector switch to another position. Reduce the sensitivity if the volume of the transmitter signal is too high and thus distorted. Increase the sensitivity if the volume is too low and a poor S/N ratio results.

4.4 Operation

Switch on the receiver and the microphones or pocket transmitters.
After switching on the transmitters, a radio connection to the individual receiver module is set up. The RF reception indicators of the individual reception channels indicate that a connection exists to the corresponding transmitters.
Switch on the following audio unit or advance the respective fader on the mixer. Speak into the microphones and match the output level of the individual reception channels to the input of the following unit with the volume controls. The AF indicators of the reception channels light up when an audio signal from the corresponding microphone is received.
To mute a microphone during operation, set the sliding switch to the center position. Then no sound will be transmitted.
After operation, switch off the receiver and do not forget to switch off the transmitters. Otherwise the batteries will be exhausted the next time they are used.

Problem Chart

Problem	Remedy
No power.	• Check connection cable of power unit and any extension cables.
No sound; receiver RF indication does not light.	• Make sure transmitter and

receiver are switched on.
• Check receiver battery indication to ensure that batteries are providing power. Replace batteries if necessary.
• Make sure that receiver is in line of sight of transmitter. If necessary, reduce distance between transmitter and receiver.
No receiver sound; receiver RF indication lights.| • Turn up the level on receiver and/or pocket transmitter.
• Check for proper connection between transmitter and mixer/amplifier.
• Apply signal to transmitter and observe receiver’s RF indication. If it lights up, the problem is elsewhere in the sound system.
Received signal is noisy or contains extraneous sounds with transmitter on.| • Check transmitter’s battery indication to ensure that battery is providing power.
• Remove local sources of HF interference, such as lighting equipment.
• Two transmitters may be operating on the same frequency. Locate and turn one off.
• Signal may be too weak. If possible, move receiver closer to transmitter.
Noise from receiver with transmitter off.| • Remove local sources of HF interference, such as lighting equipment.
• Reposition the receiver.
Momentary loss of sound as receiver is moved around performing area.| • Reposition transmitter and perform another test and observe RF indication. If audio drop-outs persist, mark dead spots in performing area and avoid them during performance.
