1 Introduction
This chapter introduces the X-DA4125 High Efficiency Power Amplifier features and functions. The
X-DA4125 High Efficiency Power Amplifier is referred to as “DA” throughout the remainder of this
manual.
The DA amplifies audio signal power it receives from audio input devices to maintain clarity and
volume when broadcast over many speakers.
Features
The DA includes the following features:
•A CLASS-D power amplifier with high efficiency and energy conservation
•Contains four independent channels
•The rated output power of each channel is 125W
•Each channel has 100V or 70V of output
•Supports balanced or unbalanced audio input
•Heat radiation through forced air-cooling mode
•Able to automatically limit output voltage
Functions
The DA includes the following main functions:
•Main and Backup Power Supplies
•Power Supply Protection
•Error! Reference source not found.
•Overload and Short Circuit Protection
•Fault Detection and Fault Logs
•Self-Test Function
Main and Backup Power Supplies
The DA includes main and backup power supplies. Typically the main power supply is used, and
only if a fault occurs is the backup power supply used. If a main power supply failure or fault occurs,
the DA front panel POWER and AC1 FAULT indicator lights turn on. In this case the DA also
signals a fault, causing the backup power supply to take over from the main power supply. Once
the main power supply has recovered from the fault, the DA reverts to using it again.
Power Supply Protection
If a power supply fault occurs, the DA automatically disconnects the main power supply.

4
Overheating Protection
When the DA internal temperature reaches 45°C, the cooling fan turns on. At temperatures below
40°C, the fan turns off.
If the temperature surpasses 75°C, the power supply is disconnected and a fault is signaled to
prevent overheating. When the temperature returns to safe levels under 70°C, the DA resumes
functioning.
Each output channel is protected against such overheating and can signal a fault if temperatures
become too high.
Overload and Short Circuit Protection
When the DA power supply detects a circuit overload or if a short circuit occurs, the DA
automatically disconnects the power. The DA remains protected and signals a fault until the
problem is fixed.
The DA is capable of detecting faults for each individual channel.
Fault Detection and Fault Logs
The main power supply of the DA can detect power failures and overheating to protect it from short
circuits and circuit overloads. When the DA detects a failure, a fault is signaled until the problem is
fixed.
The current state of the DA is shown on the front panel, and if a fault is signaled it is displayed.
Self-Test Function
The front panel user interface controls can be used to test the state of the DA. During this test all of
the interface lights turn on to show that the test is being performed. The self-test function will not
affect any other DA functions. Once the test has finished, the interface lights revert to display their
original working states.
Applications
The DA can be applied according to the needs of users. Below are two typical applications.
For the X-618 System
The DA can be part of the X-618 Public Address and Voice Alarm System, as shown below in
Figure 1.

5
Figure 1 The DA as part of the X-618 system
The procedures of the DA as part of the X-618 Public Address and Voice Alarm system are shown
below:
1. The DCS sends an audio signal to the DA. The DA then amplifies the signal.
2. The DA sends an amplified 70V or 100V audio signal back to the DCS, which in turn
distributes the signal to each speaker circuit zone.
3. The DCS sends a 22 KHz signal to the DA, which monitors the system for faults.
