Crossover EUDAC AUDIO CT-48

Crossover EUDAC AUDIO CT-48 is a high-end digital audio crossover processor (Digital Crossover Controller), applying advanced 32-bit DSP technology and high-performance 24-bit AD/DA converter.

With the ability to accurately separate signals and reproduce sharp sound, CT-48 becomes a powerful assistant for professional stage sound systems, karaoke and hall systems that require high sound detail.

32-bit DSP Technology – The Heart of the CT-48 Crossover

At the heart of the CT-48 is a 32-bit DSP – a technology that enables complex audio processing algorithms such as crossover, equalization, limiting and timing with extremely low latency.

Comes with a 24-bit AD/DA signal converter, providing smooth analog-to-digital conversion without losing the original signal quality. The 96kHz sampling frequency ensures the ability to handle high-resolution audio sources, meeting the needs of both live performances and professional recording.

Powerful customization with 128 preset modes

One of the CT-48's standout strengths is its ability to support 128 independent preset modes. Each mode can store the entire configuration state of the device, including cutoff frequency, slope, delay, and signal limiting parameters.

This is especially useful in situations where configurations need to be changed quickly between different shows or spaces. Switching presets requires just one simple operation, reducing setup time and increasing flexibility for the technician.

Flexible control interface – convenient USB & RS232

Equipped with a USB port on the front and an RS232 port on the rear, the CT-48 allows users to connect to computer control software for detailed fine-tuning of all technical parameters. The intuitive interface allows monitoring of input-output signal levels, adjusting cut-off frequencies, balancing channels, and saving configurations.

This is a big advantage over traditional analog crossovers that are only manually adjusted. Easy connection increases work efficiency, especially in professional performance environments that require high precision.

Security and User Control Features – Safety in Every System

In professional or public sound environments, preventing unauthorized interference is essential. The CT-48 incorporates a password protection function, allowing administrators to lock the entire device or individual items.

This prevents non-professional users or outside personnel from changing the carefully tuned configuration. This feature is especially useful when the device is permanently installed in halls, churches, and conference centers.

Clear signal level display – input and output LEDs

The front of the CT-48 is equipped with a series of LED lights indicating the input and output signal levels, allowing technicians to easily monitor the operation of each audio channel in real time. If the signal is deficient or overloaded, the light will flash a warning for the user to adjust immediately.

This reduces the risk of speaker damage and helps keep the sound in optimal condition. Compared to crossovers without indicator lights, this is a small but extremely useful improvement for practical operation.

Compare Crossover CT-48 with competitors in the same segment

Compared to analog lines such as Behringer CX2310 or DBX 223, EUDAC CT-48 is completely superior in terms of technology and features. While analog models only allow fixed crossovers and lack the ability to save presets, CT-48 supports precise crossovers with flexible adjustment of each frequency band, integrated 128 preset modes, software control and security features.

In addition, the CT-48's anti-interference ability and stability in complex environments are significantly higher, making the sound system operate more stably and smoothly, especially when performing in places with unstable voltage.

Benefits of integrating the CT-48 Crossover into your audio system

Using the CT-48 Crossover optimizes the frequency range for each speaker, ensuring that each speaker only operates within its ideal frequency range. This results in clear sound reproduction, reduced distortion, and extended equipment life.

In addition, CT-48 also reduces manual adjustment work, increasing the work efficiency of technicians thanks to presets. With effective anti-interference design and flexible mixing ability, the product helps the sound system operate synchronously, creating a smoother and more vivid sound field. This is the reason why CT-48 often appears in high-end sound systems today.

Common errors & solutions with CT-48

When using the CT-48, some common problems may include signal loss, distortion, or background noise. In case of signal loss, check the connection cables and make sure that the preset you are using does not have its output signal cut off. If the sound is distorted, it may be due to incorrect crossover point settings or the gain being pushed too high.

As for background noise, check the power source and avoid placing the device near wireless transmitters. Regular maintenance and firmware updates (if available) are the best ways to ensure the CT-48 is always operating properly.

Real reviews from users

Many professional users rate the CT-48 as the most valuable crossover in the price range of around 10 million VND. For high-end karaoke players, this device helps clean the sound, separate the bass - mid - treble range, support light singing and easily adjust the subwoofer.

Meanwhile, stage technicians appreciated the ability to save configurations and quickly switch between different systems. However, some new users said the software interface needed some time to get used to, and the user manual could be more detailed.

Nevertheless, satisfaction rates remain high, and Phuc Truong Audio's after-sales service is praised for its prompt and enthusiastic support.

FAQ

Which audio systems is the EUDAC CT-48 Crossover suitable for?

EUDAC AUDIO CT-48 is suitable for most professional sound systems such as: high-end karaoke systems, stage sound system, halls, bars, pubs, and even mini cinema rooms. Thanks to the ability to process 32-bit DSP digital signals, the CT-48 helps to accurately divide frequencies for each speaker group (sub, full, treble), thereby optimizing the performance of each device. Systems using separate subwoofers, multiple line speakers or requiring crossover point adjustment according to the performance space will maximize the value of this device.

Is the CT-48 easy to use for beginners?

Despite being a dedicated digital device, the CT-48 is still quite user-friendly, especially when used via PC control software. The intuitive interface, with graphical display of frequency bands, helps beginners easily visualize the frequency cutting process and system configuration. In addition, the preset feature allows you to save standard settings, just select them again when needed without having to adjust them from the beginning. However, to make the most of advanced features such as delay alignment, limiter or signal routing, you should still refer to detailed instructions from a sound technician or distributor.

Does the CT-48 Crossover need to be used with a power amplifier?

Yes, the CT-48 Crossover does not replace karaoke amplifier, but only plays the role of dividing the audio signal into different frequency bands. After dividing, the signal still needs to be amplified through a power amplifier before being sent to the speaker. CT-48 plays a central role in the signal processing chain: Mixer → Crossover CT-48 → Amplifier → Speaker. Connecting this chain correctly is a prerequisite to ensure the system operates efficiently and safely.

Does the CT-48 have a built-in microphone anti-feedback?

Is not. EUDAC AUDIO Crossover The CT-48 does not have feedback suppression because it does not process the microphone signal directly. This feature is usually integrated into a digital mixer or a standalone signal processor such as the DBX AFS. However, the CT-48's reasonable crossover and cutting out of unnecessary frequencies also indirectly helps reduce feedback resonance - especially when using a subwoofer or monitor speaker placed near the microphone.
