Encrypted radio transmission - Radiolink Spike
Aurora is a complex devices' set allowing to perform safe audio radio transmission.
The most important features of the Spike radiolink set
PERFECT SOUND QUALITY
Very clear sound, obtained thanks to modern 16bit A/C converter which guarantees great quality of the processed sound. The signal is converted into digital form by a quartz crystal, then the GMSK modulation proceeds, followed by transmission in form of frames to the receiver (radio).
LOW NOISE LEVEL
Conversion to the digital signal causes reducing disturbance and noise level. As a result the user obtains a clear sound. Demodulation in the receiver converts the signal into the analog form again. All the distortions are corrected to obtain the best possible audio quality.
STABLE TRNASMITTER OPERATION
The RMD 300 transmitter continues its operation even in case when the voltage does not reach 2,2V at the given moment (it is the recommended supply voltage). A temporary attenuation of signal transmission is possible, yet the signal is not going to be ceased. Apart from that, the transmitter is equipped with:
- External antenna o the Spike radiolink
- High-sensitivity microphone
- Automatic activation system (after inserting the battery)
- Remote control – optionally.
SOLID TRANSMITTER CONSTRUCTION
The components of PRK 045 SH receiver are protected with a solid metal casing. Additionally, the receiver allows to choose the channel of receiving, setting the desired sound level and displays the remaining power level of the device. It has the following input/outputs:
- Antenna
- Headphones
- Sound recorder output.
