- Antenna cables for active antenna supply
- Transformer-balanced audio outputs
- HDX noise reduction system with signal-to-noise ratio less than 120 dB(A)
- Ethernet for connecting to a PC
- Monitoring and control using Sennheiser WSM PC software
- User-friendly menu interface with two-color backlit graphic display (red as a warning)
- Transmitters can be configured from the receiver menu
- Transmitters can be synchronized over the infrared interface
- 4 selectable equalizer presets
- Soundcheck mode for monitoring transmission conditions
- Adjustable headphone connection
Delivery Includes
- EM 2050 stationary twin receiver
- 3 mains cables (EU, UK, and US)
- 2 rod antennas
- 4 self-adhesive device feet
- Instruction manual
- Supplementary frequency sheet
- Supplementary RF power sheet
CONSUMER ALERT
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at

Glossary
| Audio output level (balanced) |
| Logarithmic value of the audio output voltage based on a standard reference value. A balanced circuit or connection uses separate signal lines for sending a signal, returning the signal and ground (3-pole connection). |
| Booster |
| RF amplifier which is powered via the antenna cable, which means that it can easily be connected into existing wiring. |
| Cascadable |
| Ability of units to be daisy-chained. For example, charging units can be daisy-chained (connected in series) and powered by only one power supply unit. |
| Compander |
| Also known as noise reduction system. A system which improves the signal-to-noise ratio by compressing the dynamics on the transmitter side using a compressor, and subsequently restores the normal dynamics on the receiver side using an expander. |
| Frequency response |
| The frequency response of a microphone is given within the limits defined by the manufacturer. In studio condenser microphones it is generally within the range of between 20 Hz and 20 kHz. |
| Gain |
| Ratio of input voltage to output voltage. A negative value means an attenuation. |
| Intermodulation spacing |
| In RF transmission, the different carrier frequencies produce not only hamonics (integral multiples) but also a large number of (odd number) sums and differences of integral multiples of the input frequency components. These limit the number of usable frequencies within a certain band. The intermodulation spacing gives the level difference between the carrier frequency and these unwanted frequencies. |
| Operating temperature |
| Gives the range of temperatures at which a unit can be operated without damage. |
| Peak deviation |
| Maximum permissible deviation for FM. |
| Power supply |
| Description of the power source used for powering a unit, for example mains, battery, rechargeable accupack, etc. |
| RF frequency range |
| The range of frequencies to which a unit (e.g. a receiver) can be tuned. |
| Squelch |
| Adjustable value for muting a receiver if the RF power received falls below a certain threshold value.
|
| Switching bandwidth |
| The frequency band in which frequencies can be switched directly. |
| Total harmonic distortion (THD) |
| Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%. |
| XLR connector |
| Most common form of connector in audio studio technology. |
