Description
Axel Technology LYNX Digital Broadcast FM Tuner/monitoring.
Lynx is an evolved Broadcast Digital FM Tuner, designed for receiving, monitoring, visualize and listen the FM radio signals. The built in web interface allow to multiple users to visualize all the parameters and details of the incoming signal. The tuned frequency’s audio is available on the analog balanced output (XLR), on the digital output AES/EBU (XLR), on the headphone output and via streaming. At the same time. The quality and accuracy of the built-in tuner allow a very strict analysis of the tuned frequency, the modulation and the RDS data decoding. The Lynx’s display always show the tuned frequency and, cyclically, all the following parameters:
Receiving:
– RF Level incoming
– Multipath
– Carrier Offset
Deviation:
– MPX
– Audio
– Pilot and RDS
Decoding RDS:
– PS
– PI
– BLER
– TA
– TP
– MS
– DI
– PTY / PTYN
– AF Presence
– RT / RT
– TMC
The display allow you also to finetune and adjust all the setting of Lynx as:
– IP Ethernet port
– Digital and Analog level output
– Time and treshold alarm
– Headphone level
On the frontal panel the headphone output allow you to listen the tuned frequency. The led panel (STATU LED PANEL) show you in a clear way the receiving status:
– Tuned
– Stereo
– RDS
– 3 different alarms: Low RD, Low Audio and RDS Errors.
The built in web server allow to preview the following details:
