4.2 Features
The
AUD2MP1
audio distributor has been designed to be integrated in radio
transmission systems with dual exciter, or in any case in all those applications
where there is need to divide the audio sources of different nature into two outputs
each. Different configurations are available depending on type and numbers of
signals to distribute.
It is totally passive and any power source does not require, this solution has been
adopted to provide maximum reliability and to not waste the redundancy offered
by the dual output, by using of power systems that may generate failures to both
channels.
The distributor has seven distinct sections: the first two suitable for analog audio
(L & R), four that can divide an unbalanced MPX/RDS/SCA1/SCA2 signal and the
last able to split the AES-EBU digital signal.
In detail, the
AUD2MP1
has a separate Left and Right analog audio inputs that
accept mono signals from DC to over 20 kHz, the signal is split and sent to two
balanced outputs (XLR) with a level loss of about 6dB.
The AES-EBU digital input is a balanced type (XLR) with a transformer and it has
an input impedance of 110 ohms .The signal of this input is split and sent to two
balanced outputs (XLR).
The MPX/RDS/SCA1/SCA2 unbalanced input (BNC) is able to split a MPX audio
signal on two unbalanced outputs (BNC), it accepts audio signals from DC to
100KHz.
