Special Design Features

Congratulations on your purchase of a Proceed BPA! While your new amplifier is straightforward in its use, it includes several design features which are responsible for its outstanding performance. A few of these are given below.

Consistent with the finest amplifiers, your Proceed BPA is a true “multiple monau- ral” design. Each audio channel has its own, dedicated power supply—including a separate 300VA toroidal transformer for each channel. This approach reduces crosstalk between audio channels for superior imaging and reproduction of acoustic space. The demands placed on one channel have virtually no effect on the performance of the other channel(s).

A critical factor in the ultimate performance of an amplifier is its “power supply impedance,” which can be loosely thought of as the freedom with which the au- dio circuitry has access to the power it needs, when it needs it. The design of your Proceed BPA has addressed this important characteristic in a comprehensive fashion. For example, the power supply capacitors (which act as “reservoirs” of power for the amplifier circuitry) are mounted directly to the printed circuit board, immediately adjacent to the output transistors (which require the greatest amount of current). The layout of the circuitry uses short, thick traces for high current paths. Internal current capability is further enhanced with high purity copper buss bars. This attention to detail yields an optimal environment in which the amplifier may operate to its maximum potential.

Each channel of your BPA is individually configurable to receive either balanced or single-ended inputs. This approach allows you to take full advantage of the greater immunity from noise, RFI, and EMI which balanced transmission of audio signals offers on any preamp-to-amplifier connection where it is supported. At the same time, any or all channels of the amplifier may be configured for single- ended inputs to maintain compatibility with the majority of preamplifiers avail- able today. The gain structure of the BPA adjusts automatically when you select different inputs to facilitate this “mix and match” approach.

Each channel of your Proceed BPA uses eight 150 watt power transistors. These transistors are all individually tested and sorted, and are used in matched sets to ensure that no one transistor bears a disproportionate part of the overall load. The combination of an “overbuilt” design specification and extraordinary attention to detail in manufacturing improves performance, reliability, and longevity.

Your Proceed amplifier will shut itself down if it senses either the presence of DC (direct current) at the output or an unsafe operating temperature. In either case, a power relay will cause the amplifier to be disconnected from the AC mains. In addition, the AC input to each transformer is fused to protect against excessive current conditions such as driving shorted outputs. Finally, inrush limit- ing prevents premature aging of power supply components during power-up, and switches off-line once the power supply has been charged.

BPA 3, BPA 2 specifications

Madrigal Imaging is at the forefront of innovative imaging technologies, particularly with its BPA 2 and BPA 3 systems, which are designed to enhance diagnostic capabilities in medical imaging. These systems are specifically engineered to meet the demands of modern medical practices while providing high-quality imaging results.

The BPA 2 is renowned for its speed and efficiency. One of its main features is the advanced digital signal processing technology that allows for clearer images in less time. This system employs a unique algorithm that enhances image acquisition, resulting in improved visibility of anatomical structures. The BPA 2 also supports a wide range of imaging modalities, including X-ray, MRI, and ultrasound, making it a versatile tool in any medical facility.

Another significant feature of the BPA 2 is its intuitive user interface, designed to streamline workflow for healthcare professionals. The user-friendly design minimizes the learning curve for new users and allows for quick adjustments to imaging parameters. This enhances productivity, enabling healthcare providers to focus more on patient care and less on navigating complex systems.

Moving to the BPA 3, this next-generation imaging system builds on the strengths of the BPA 2 and incorporates cutting-edge technologies. One of its key characteristics is the integration of Artificial Intelligence (AI) and machine learning algorithms that assist radiologists by automatically analyzing images and highlighting areas of concern. This not only aids in faster diagnosis but also helps in reducing human error.

Furthermore, the BPA 3 features an advanced image reconstruction technology that dramatically improves image quality. This system utilizes deep learning algorithms to produce high-resolution images with reduced noise, giving clinicians a clearer view of the patient’s condition. Additionally, BPA 3 is designed with an emphasis on patient comfort. Its ergonomic design and faster imaging times are intended to minimize radiation exposure and reduce patient anxiety during procedures.

Both the BPA 2 and BPA 3 are equipped with robust data management solutions, allowing for seamless integration with existing hospital information systems. This ensures that imaging data can be easily shared among healthcare providers, enhancing collaboration and improving patient outcomes.

Overall, Madrigal Imaging's BPA 2 and BPA 3 systems represent significant advancements in medical imaging technology, combining high-quality image capture with user-friendly interfaces and innovative features that prioritize both patient care and operational efficiency.
