Power and Amplification

The A-3624D delivers 240 watts of output power, making it suitable for medium to large spaces that require robust sound reinforcement. The amplifier is designed for continuous, reliable operation, supporting both low-impedance (4 to 16 ohms) and high-impedance (100V line) speaker systems. This flexibility ensures that the unit can be integrated into existing setups or new installations with ease.

Digital Signal Processing (DSP)

One of the standout features of the TOA A-3624D is its use of digital signal processing (DSP), which ensures high-quality sound output with minimal distortion. The DSP allows for fine-tuning of audio signals, ensuring optimal sound clarity even in complex acoustic environments. Built-in functions such as equalization (EQ), bass and treble controls, and loudness adjustments help in tailoring the audio output to suit different sound system configurations and room acoustics.

The automatic gain control (AGC) feature maintains consistent volume levels, preventing sudden audio peaks or dips, which is particularly useful for announcements or background music in dynamic environments.

Multiple Inputs and Flexibility

The A-3624D offers a range of input options, providing great versatility for various audio sources. It includes:

• 3 balanced mic/line inputs (XLR/Euroblock terminals), suitable for microphones or external devices.
• 2 auxiliary inputs, allowing connection to external audio sources like music players, smartphones, or other devices.
• 1 telephone input for integration with telephone paging systems.
• Remote volume control terminals to manage volume levels from a distance, ideal for setups where the amplifier is located in a separate room from the user.

Each input channel has its own volume control and tone adjustment capabilities, enabling fine-tuning of individual audio sources to achieve a balanced mix.

Priority Control and Paging Functions

The A-3624D features priority control, which is essential for public address systems where certain inputs (like microphones or emergency announcements) must override other audio signals. This ensures that important messages are heard clearly, even if background music or other audio is playing.

There is also a chime function for paging, which plays a pre-set chime tone before an announcement, signaling that an announcement is about to begin.

Outputs

In addition to speaker outputs, the A-3624D has a range of other outputs, making it a central hub for more complex audio systems:

• Speaker outputs: Supports both low-impedance (4 to 16 ohms) and high-impedance (70V/100V) systems.
• Preamp output: Allows the connection of an external power amplifier for additional sound reinforcement if needed.
• Recording output: Lets users connect recording devices to capture live audio for playback or analysis.

User-Friendly Design

The front panel of the amplifier is designed for intuitive control, featuring individual volume knobs for each input, along with master volume control. This makes it easy to adjust levels on the fly without needing advanced technical knowledge. There are also LED indicators for power, signal presence, and protection, helping users monitor the system status at a glance.

Protection Features

To ensure durability and consistent operation, the A-3624D comes equipped with several protection mechanisms:

• Overload protection: Prevents damage caused by excessive loads or short circuits.
• Thermal protection: Ensures the amplifier doesn’t overheat during prolonged use, which is particularly important in large installations or environments where the system is in use for extended periods.
• DC output protection: Safeguards connected speakers and other components from damage caused by direct current surges.

Energy Efficiency

The A-3624D is designed with energy efficiency in mind, utilizing Class-D amplifier technology, which reduces power consumption and heat output. This makes it more efficient compared to older analog amplifiers and allows for longer, more reliable operation without the need for large cooling systems.

Expandability and Integration

The amplifier can be integrated into a variety of sound systems. It is compatible with TOA’s other components and products, allowing for system expansion or the addition of more specialized functionality as needed. Whether installed in a small room or part of a large building-wide PA system, the A-3624D provides the flexibility and scalability required for different use cases.

The TOA A-3624D 240-watt digital mixer amplifier is a versatile and robust solution for public address and sound reinforcement systems. With its powerful output, flexible input and output options, digital signal processing capabilities, and user-friendly design, it is well-suited for a wide range of commercial and professional applications. Whether for background music, paging, or emergency announcements, the A-3624D ensures high-quality sound delivery with reliability and ease of use.
