Desiun Features of the A4

+RUBITM Power Supply (Rapid-Use Branched Impulse) Our new power supply eliminates “power sags” during low frequency reproduction by rapidly increasing the duty cycle, stabilizing the power supply and allow- ing it to deliver the power required when reproducing low frequencies. Also, greater reserve gate power is now stored for low voltage conditions that occur during extreme conditions.

+STACTTM (Stabilized Apex Current lopology) Reduces power supply stress by 50%. Use of inverted channels usually degrades the stereo image due to phase reversal of even order harmonic distortion that oc- curs between the inverted channels. In the STACT design inversion is done at the power amplifier drive stage. Since the fully symmetrical power amplifier produces no even harmonic distortion itself and all preamp cir- cuitry (which does produce even harmonics) is run completely in phase, no even harmonic distortion phase reversal occurs.

+TridentTM Protection Three types of protection for RUBICON amplifiers:

1.Output protection against short circuits or improper loads.

2.Ground fault detection shuts down the amplifier when a significant (5 volt or greater) voltage fluctuation occurs between audio ground and bat- tery ground.

3.Thermal protection will shut the amplifier down in extreme thermal conditions.

+Hawkins Bass Control Provides focused subwoofer boost and routes wasted subsonic power to the audible bandwidth. The A4 contains the fixed Hawkins Bass Control which allows you to boost bass 6dB at 45Hz. A built-in subsonic filter at 45Hz helps protect the speakers.

+Harmonic Bass AlignmentTM The 2nd and 3rd order harmonic peaks are critically aligned to fundamental peaks at low frequencies. This pro- duces tighter, more accurate bass reproduction.

+Drive Delay II Muting TM Amplifier section now powers up 2 - 3 seconds after power supply, eliminating turn on pops. Turn off process is reversed. Amplifier section turns off first, followed by power supply.

+Dynamically Optimized Power Grid TM Power grid is now evenly dis- tributed between primary and secondary power supplies, providing greater dynamics and improved RF filtering.

+ChassisinkTM All transistors are sandwiched between the circuit board and the heatsink to provide cool efficient amplifier operation in a smaller package.

+Continuously Variable Lowpass Crossover Networks 12dB/oct low pass crossover variable from 50 to 220Hz.

+Built-in Staggered S.I.P. Crossover Networks Built-in high pass elec- tronic crossover is designed to send high pass information to the ampli- fier with a 12dB/oct slope.

+Flexible Input Level Control 200mV to 5V input sensitivity. Stereo level control allows user to optimize system level control.

+Symmetrical Discrete Balanced Class A Drive Boards Auto-adjusts for linear performance in low impedance loads.

Angina A4 specifications

Soundstream Technologies has made significant strides in the audio technology space with their latest innovation, the Angina A4. This high-fidelity sound system is designed for audiophiles who seek unparalleled sound quality and features to enhance their listening experience.

One of the standout characteristics of the Angina A4 is its advanced digital signal processing (DSP) technology. This feature allows for real-time audio adjustments to ensure that the sound output is perfectly tailored to the user's preferences and the acoustics of the listening environment. The DSP optimizes the sound stage, providing a more immersive experience whether you’re enjoying music, movies, or gaming.

The Angina A4 is equipped with a state-of-the-art Bluetooth 5.0 module, ensuring a stable connection with minimal latency. This allows users to stream high-quality audio from their devices without compromising sound integrity. The inclusion of aptX HD codec support enhances this capability further, allowing for lossless audio streaming that preserves the nuances of the original recording.

In terms of design, the Angina A4 is sleek and modern, featuring premium materials that not only contribute to its aesthetic appeal but also enhance acoustic performance. The cabinet is crafted from dense wood, which minimizes resonance and provides a solid foundation for the speaker units. Coupled with specially designed bass ports, this feature ensures deep, powerful low frequencies without distortion.

The system also boasts multiple connectivity options, including traditional wired connections such as RCA and optical inputs. This versatility allows users to integrate the Angina A4 into a variety of audio setups, from home theaters to professional studios. Additionally, built-in Wi-Fi capability enables access to streaming services, making it a fully functional multimedia hub.

Another major advantage of the Angina A4 is its customizability. With adjustable EQ settings and various sound profiles, users can easily switch between different audio presets based on their preferences or the type of content they're consuming. This personalization aspect is increasingly important in today’s audio-centric world where user experience plays a crucial role.

In summary, Soundstream Technologies' Angina A4 is a remarkable combination of cutting-edge technology and thoughtful design. With features like advanced DSP, Bluetooth 5.0 connectivity, versatile input options, and customizable audio settings, it stands out as a premier choice for discerning listeners seeking both quality and flexibility in their audio experiences.
