multi channel receiver, musical, broadcast - applications
General Description
The EM 1046 receiver module is at the heart of any 5000 series receiver system.
All functions can be quickly checked via an alphanumeric multi-function display panel, LED bargraphs and individual LEDs. Due to the menu-assisted operation, parameters can quickly and easily be modified.
Features
- Modular multi-channel receiver system for demanding musical and broadcast applications
- Large mainframe houses up to 8 true diversity receiver modules
- Small mainframe houses up to 3 true diversity receiver modules
- Several mainframes can be daisy-chained
- Indication of transmitter battery status (only with Sennheiser transmitters transmitting battery status information)
- "HiDyn plus" noise reduction system
- Mikroport computer display for remote controlling large systems

Glossary
| Adjacent channel rejection |
| The ability of a receiver to respond to the desired signal and to reject signals from adjacent channels. |
| 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 (microphone) |
| 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. |
| Image rejection |
| The ratio of actual receiving frequency to image frequency. Given in dB. |
| Intermodulation |
| In RF transmission, the different carrier frequencies produce not only harmonics (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. |
| Intermodulation attenuation |
| 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. |
| Limiter |
| An electronic circuit used to prevent the amplitude of an electric signal from exceeding a specified value. |
| Min. channel spacing |
| The minimum distance between FM signals which has to be observed in order to avoid interference with adjacent channels. |
| Nominal deviation |
| Also known as reference deviation. The nominal deviation has been fixed at 40kHz to be able to give comparable technical data. |
| Peak deviation |
| Maximum permissible deviation for FM. |
| RF frequency range |
| The range of frequencies to which a unit (e.g. a receiver) can be tuned. |
| RF sensitivity |
| The ratio of signal level at a unit´s input to signal level at its output. |
| 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. |
