First Aid

All personnel engaged in equipment installation, operation and maintenance must be familiar with first aid procedures and routines.
3.1 Electric shock treatment
3.1.1 If the victim is unconscious
Follow the first aid procedures outlined below.

Lay the victim down on his/her back on a firm surface.
the neck and tilt the head backward to free the airway system (Figure 1).
If needed, open the victim’s mouth and check for breathing.
If there is no breathing, start artificial respiration without delay (Figure 2) as follows: tilt the head backward, pinch the nostrils, seal your mouth around the victim’s mouth and give four fast rescue breaths.
Check for the heartbeat (Figure 3); if there is no heartbeat, begin chest compressions immediately (Figure 4) placing your hands in the center of the victim’s chest (Figure 5).
One rescuer: give 2 quick rescue breaths after every 15 compressions.
Two rescuers: one rescue breath after every 5 compressions.

General Description

The AUD2MP1 is a passive 2-way audio distributor, Digital/MPX+RDS+SCA1+SCA2/ Analog stereo or mono, working in a wide range of levels.
The AUD2MP1 is designed to be contained in a 19” rack box of 1HE.
4.1 Unpacking
The package contains:

1 AUD2MP1
1 Quick Reference
1 CD Manual

The following accessories are also available from Your R.V.R. Dealer:

Accessories, spare parts, and cables

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 the type and number 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 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 an MPX audio signal on two unbalanced outputs (BNC), it accepts audio signals from DC to 100KHz.
The outputs of this section are calibrated to be connected to outputs with a typical impedance of 10KOhm.
The insertion loss of the two outputs is typical of 6dB. The distributor AUD2MP1 does not require any routine maintenance.
The AUD2MP1 audio distributor comes in different configurations summarized below:

Version V1: 2-Way passive audio splitter, digital(AES-EBU)/MPX/Analog(L&R) stereo or mono.
Version V2: 2-Way passive audio splitter, digital(AES-EBU)/MPX+RDS/ Analog(L&R) stereo or mono.
Version V3: 2-Way passive audio splitter, digital(AES-EBU)/MPX+RDS+SCA1/ Analog(L&R) stereo or mono.
Version V4: 2-Way passive audio splitter, digital(AES-EBU)/ MPX+RDS+SCA1+SCA2/Analog(L&R) stereo or mono.

Quick guide for installation and use

This section provides a step-by-step description of equipment installation and configuration procedure. Follow these procedures closely upon first power-on and each time any change is made to the general configuration, such as when a new transmission station is added or the equipment is replaced.
Once the desired configuration has been set up, no more settings are required for normal operation; at each power-up (even after an accidental shutdown), the equipment defaults to the parameters set during the initial configuration procedure.
The topics covered in this section are discussed at greater length in the next sections, with detailed descriptions of all hardware and firmware features and capabilities. Please see the relevant sections for additional details.
IMPORTANT: When configuring and testing the transmitter in which the equipment is integrated, be sure to have the Final Test Table supplied with the equipment ready at hand throughout the whole procedure; the Final Test Table lists all operating parameters as a set and tested at the factory.
5.1 Preparation
5.1.1 Preliminary checks
Unpack the audio device and immediately inspect it for transport damage. Ensure that all connectors are in perfect condition.
Connect all audio inputs required from the audio sources available.
Connect all audio outputs to the audio devices that need them.
