Performance and Sound Quality

The TD 4800 is renowned for its exceptional sound quality, delivering clear, accurate, and powerful audio across the entire frequency spectrum. Its high power output ensures that it can drive even the most demanding speaker systems with ease, making it suitable for large venues and high SPL applications.

Power and Headroom

With 2400W per channel at 4Ω and 1600W per channel at 8Ω, the TD 4800 provides ample power for a variety of applications. The high power output ensures that there is plenty of headroom, reducing the risk of clipping and distortion even at high volumes. This makes it ideal for live sound environments where maintaining audio clarity and consistency is crucial.

Frequency Response and Clarity

The amplifier’s frequency response of 20Hz to 20kHz ensures that it can accurately reproduce the full range of human hearing. The TD 4800 delivers tight, punchy bass, detailed mids, and clear, sparkling highs. The low total harmonic distortion (THD) of less than 0.05% guarantees that the audio remains clean and free from unwanted harmonics, even at high power levels.

Damping Factor

A high damping factor (> 500 at 8Ω) indicates the TD 4800’s ability to control speaker movement, particularly in the low frequencies. This results in tighter bass response and improved overall sound accuracy. The amplifier’s control over the speakers ensures that transients are reproduced accurately, adding to the clarity and impact of the audio.

Protection and Reliability

One of the standout features of the TD 4800 is its comprehensive protection circuitry, which enhances reliability and ensures safe operation under various conditions. The protection features include:

– Overload Protection: Prevents damage to the amplifier and connected speakers by limiting the output when excessive current draw is detected.

– Short Circuit Protection: Automatically shuts down the amplifier if a short circuit is detected, protecting both the amplifier and the speakers.

– DC Protection: Detects and blocks DC voltage from reaching the speakers, preventing potential damage.

– Thermal Protection: Monitors the internal temperature and activates the cooling fan as needed. If the temperature exceeds safe limits, the amplifier will shut down to prevent overheating.

– RF Protection: Shields the amplifier from radio frequency interference, ensuring clean audio output without unwanted noise.

These protection mechanisms ensure that the TD 4800 can operate reliably even in challenging conditions, making it a dependable choice for professional audio applications.

Applications

The versatility of the TD 4800 makes it suitable for a wide range of applications, including:

Live Sound Reinforcement The TD 4800 is ideal for live sound reinforcement, providing the power and clarity needed for concerts, festivals, and other live events. Its ability to drive large PA systems with high SPL ensures that every detail of the performance is heard clearly, even in large venues.

Studio and Recording: In studio environments, the TD 4800 excels in driving reference monitors, providing accurate and detailed sound reproduction. Its low noise floor and high SNR make it suitable for critical listening and mixing tasks, where precision is paramount.

Fixed Installations: For fixed installations in theaters, houses of worship, and conference centers, the TD 4800 offers reliability and consistent performance. Its robust build and comprehensive protection features ensure that it can handle continuous operation without issues.
