1 Introduction
This chapter introduces the KB-DA1500 High Efficiency Power Amplifier features and
functions. The KB-DA1500 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
The rated output power is 500W
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:
Power Supply Protection
Temperature Regulation
Overload and Short Circuit Protection
Fault Detection and Fault Logs
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.

3 Installation
This chapter describes how to install the DA hardware in step-by-step instructions.
Preparing for Installation
Make sure the following are prepared prior to DA installation:
Tools
Materials
Cables and Wires
Package Inspection
Tools
For the installation of the DA, prepare the following tools:
Anti-static wrist strap
Anti-static gloves
Cutting pliers
Wire cutters
Electrical cable crimping pliers
Materials
For the installation of the DA, prepare the following materials:
Insulation tape
Wire buckles
Wire labels
Cables and Wires
For the installation of the DA, prepare the following cables:
Backup power cable
The backup power cable and main power cable are required to have matching
specifications.

9
Audio output cable
The cable should be unshielded.
Notice:
The use of a high-grade, high transmission capacity speaker cable is strongly
recommended.
The longer the cable, the thicker it should be to retain transmitted audio quality.
Select the appropriate audio cable according to the installation situation and
environment.
Package Inspection
Check the packaging and make sure all items specified on the Packing list are intact
(see Chapter 5). If an item is missing, please contact the appropriate vendor.
Connecting the Cables
These cables include the grounding cable, main and backup power cables, audio input
cable and audio output cable.
Notice:
When connecting cables, make sure the DA power switch is turned off.
Plug the cables into the correct ports and tighten the cable terminal screws.
Power and data wires must be separated and not be wrapped in the same
cable’s insulation.
Keeping the power and data cables separate helps to avoid signal interference.
Grounding Cable
The grounding cable connects to the DA grounding cable port.

10
Notice:
Do not connect the grounding output cable with the grounding input cable as
this action causes a short circuit to occur.
Audio Input Cable
user can select the input method according to the equipment storage environment.
Use RJ45 Port:
The See Table 3 for the pin descriptions.
Note:
Do not use the RJ45 port and terminal blocks at same time.
Instead, plug the CAT5 cable into the RJ45 port.
Use Terminal blocks:
Notice:
If the audio input cable is supplied by the installation personnel, the cable
must be shielded.
DA has a balanced input connection. A balanced connection is recommended to
reduce AC power interference, especially when using a long cable. For short cables
that have an unbalanced connection, the signal impedance should be less than 600
ohms.
The following steps describe connecting a balanced input connection:
1. Strip 7 mm of the input cable and connect it to the input terminal, and then tighten
the screws to secure the wires, as shown in Figure 10. See Figure 1 for port
descriptions.

2. Connect the input terminals to their corresponding input ports, as shown in 0 2.

Output Cable
1. Strip 7 mm of insulation off the output cable, and connect it to the output terminal,
as shown in 03.

Completing Installation and Commissioning
Once the DA hardware and cables are installed, complete the following commissioning
procedures:
1. Set the audio volume to a minimum level.
