AM (Audio Monitor) multi-channel audio monitor is designed by
Suzhou Fortune technology Co., Ltd to catch up with digital reform
of radio broadcasting and transmission. It integrates audio
collection, analysis, display and alarm functions.
Features:
It adopts embedded system, industrial computer to improve data
process and display ability.
Standard VGA Output which can be connected with PC Monitor or LCD
TV to realize the 640*480 or even 800*600 HD Display. On the other
hand, by the convert equipment to obtain PAL Video Output which can
be connected with TV Monitor.
Selectable analog and digital (AES/EBU) input modules, at most
support 32 analog or 16 digital (AES/EBU) channels.
Definite Sampling and display audio amplitude, dB graduated scale
and peak level which accord with state standard. In addition, it
provides two displays of VU Meter and PPM with 60dB dynamic range
and analog +10db Gain switch as well as reference level adjusted in
the software.
Audio-loss, modulation and close-loop alarm function (AES signal
monitor in digital boards) and users can preset different alarm
parameters on each channel, including threshold, control time and
alarm period and can also terminal alarm by manual.
Human-based menu with radio station label
Log history record and view function including boot-up and shutdown
time, appearing and recovering time of abnormal situations which
can be sent to PC.
By RS485 or Ethernet connector, AM can build monitor network which
can be connected to main control system.
Update software to extend functions
