DSW104 Digital Audio Intelligent Emergency Switch is designed as
new professional intelligent digital audio control equipment. It
features in strong monitor and control, high reliability and
internal automatic music system. The high quality makes it passed
the test from state administration of radio, film and television
and suitable for the use of radio station and main control system.
Features:
The first channel has the function of Bypass when power supply is
cut off
AES/EBU inputs accord with AES3 standard. (AES3-1992)
Priority of switching order and accident alarm can be set with
three trigger modes: AES signal loss, error code and audio signal
interrupting.
Error code indicator and AES signal loss alarm
Manual switch and lock function
Switching without noise
Analog stereo balanced output, maximum output level: +24dBu
Real-time level display on the LCD panel
Dimension: 19-inch, 1U
Specifications:
Sampling Rate: 32K44.1K48K
AES Input: 110balanced XLR-type connector0.2~5Vp-p
AES Output: 110balanced XLR-type connector
Functions:
Three AES/EBU digital audio input channels and one channel for
internal background music source. The system can select one of the
four channels as input signal. On the other hand, there are one
AES/EBU digital output channel, one channel for the same balanced
analog stereo output and one stereo channel for pre-listen and
monitor which leave out the D/A converter.
It can realize real-time monitor and display audio amplitude of
each channel, providing audio-loss” and contrast” monitor modes to
determine the accident. Both of the level threshold and time
threshold can be set by users and it can also be selected the
status from ON” OFF” and automatic switching”
Alarm and switching during alarm period can be set in order to turn
off the alarm and switching function in case of unexpected
operation before and after broadcasting. There are seven different
broadcast sheets every week with two periods each day.
Real-time monitor AES3 signals from each channel. If audio-loss, it
will automatically trigger alarm and immediately switch according
to the previous settings.
Priority of the four channels switching order can be set. If
accident happens, system will switch automatically according to the
order. The first channel is default bypass on the condition of
shutdown.
Manual and automatic switching mode. Users can select whether
switch to the high-priority channel when the signal comes back.
It will play the internal background music automatically when all
the external signals (main and spare signals) are interrupted.
Internal music system adopts solid IC memory and MUSICAM coding,
which can broadcast more than half an hour as well as circular
playing. In addition, the music can be downloaded by the USB
connection.
It provides synchronous and asynchronous mode to digital audio
output. Synchronization mode contains internal and external modes.
By headphone, users can pre-listen every input channel and monitor
broadcast signals.
By PC connection and remote control software users can monitor
several sets of DSW104 or ASW104 at the same time, switch between
them, correct time and set menus. In addition, with the remote
control software, DSW104 provides the functions of switching on
time and accident log record.
