Frequently Asked Questions about 1200.4 EVOPS

What are the performance features of the Soundigital 1200.4 EVOPS?

The Soundigital 1200.4 EVOPS features a maximum power output of 4 x 300 Watts RMS at 1 or 2 Ohms. It offers flexible operating modes with bridging options at 4 Ohms with 2 x 396 WRMS or 2 x 600 WRMS at 2 Ohms. The amplifier variants for 4 Ohms provide 4 x 198 WRMS at 4 Ohms and 4 x 300 WRMS at 2 Ohms. Additionally, it boasts an impressive efficiency of 84% or 82% depending on the resistance, complemented by a tuned frequency response of 5Hz to 22kHz, making it ideal for various audio applications.

What protection does the Soundigital 1200.4 EVOPS offer?

The Soundigital 1200.4 EVOPS is designed to be robust against external influences. It has a conformal coating and optimized internal electrical components that enhance its durability. With an IP 64 protection class, it offers protection against vibrations and corrosion, which is particularly advantageous for mobile use in vehicles or under demanding environmental conditions. This combination of high-quality materials and technical execution ensures that your amplifier operates reliably even under challenging conditions.

How do the operating parameters affect the function of the 1200.4 EVOPS?

The amplifier operates within a voltage range of 8V to 16V and has a current consumption of 49 A during normal music operation, which can reach up to 99 A at maximum load. A recommended fuse capacity of 60 A ensures safe operation. The damping factor of 200 supports control of the speaker movement, allowing for precise sound output. These parameters are crucial for delivering consistent and stable performance when reproducing audio signals, especially in varying voltage environments.

What frequency range options does the amplifier offer?

The Soundigital 1200.4 EVOPS features a flexible crossover. The high-pass filter (HPF) covers a range from 45Hz to 850Hz, while the low-pass filter (LPF) processes the same frequency range from 45Hz to 850Hz. These settings allow for fine-tuning of audio signals for specific speaker applications, making the amplifier particularly adaptable for diverse audio system configurations. This ability to precisely control frequencies significantly enhances sound quality and allows for optimal adjustment to the individual acoustic environment.

How important is the signal-to-noise ratio in the 1200.4 EVOPS?

The signal-to-noise ratio (SNR) of the Soundigital 1200.4 EVOPS is 88dB, which means it can reproduce a clear and noise-free audio signal. A high SNR is crucial for accurate music playback, as it essentially measures the ratio between the audio signal and any disturbing background noise. An SNR of 88dB makes this amplifier suitable for discerning sound enthusiasts who expect pure sound quality in their music playback. This aspect is particularly important when used under dynamic operating conditions to ensure the enjoyment of unadulterated sound details.

What technical improvements have been made to the audio quality of the Soundigital 1200.4 EVOPS?

The Soundigital 1200.4 EVOPS is equipped with technical improvements to optimize its audio quality. These include high-quality Tiffany Style RCA connectors that ensure a better connection, as well as gold tracing on the circuit boards, which provides corrosion resistance and improved signal transmission. The conformal coating of the circuit board increases protection against weather and environmental factors, while optimized electrical components enable efficient and low-loss signal processing. This combination results in excellent audio performance and a clearer, more detailed sound image.

What are the dimensions of the Soundigital 1200.4 EVOPS and how do they affect installation?

The Soundigital 1200.4 EVOPS has compact dimensions of 16.6 x 14.9 x 6.2 cm, allowing for easy integration into various vehicles. Due to its manageable size, it is ideal for installation in limited spaces such as under the seat or in the trunk. However, care should be taken to ensure adequate ventilation during placement to avoid overheating. This design allows flexibility in choosing the installation location and promotes discreet integration into the vehicle layout without significantly affecting the interior design.

How does the amplifier integrate into an audio system in terms of power consumption?

The Soundigital 1200.4 EVOPS has a power consumption of 49 A during music operation. Under maximum load, this value can rise to 99 A, which requires an adequate power supply with a suitable fuse of 60 A. This power management ensures continuous performance in electrical systems and prevents audio signal degradation due to power instabilities. These parameters are crucial so that even at high volumes, the amplifier can fully utilize its power potential without overheating or shutting down.

Can the Soundigital 1200.4 EVOPS be easily adjusted with the crossovers?

Yes, the Soundigital 1200.4 EVOPS offers flexible adjustment options through its crossovers. The high-pass and low-pass filters can be adjusted between 45Hz and 850Hz, allowing you to customize the sound output. This variability is ideal for supporting different speaker types and listening preferences. The easy adjustment of the crossovers enables both beginners and experienced audio enthusiasts to optimize the audio system to their needs. Effective frequency control also significantly improves overall audio quality.

What is the significance of the THD + N specification for this amplifier?

The Soundigital 1200.4 EVOPS has a THD + N value of 0.1%, which is remarkable for a powerful 4-channel amplifier. THD + N stands for Total Harmonic Distortion plus Noise and measures distortions and noise in the output signal. A low value like this indicates that the amplifier reproduces the original audio signal almost unchanged, preserving detail fidelity. This specification ensures high sound quality, which is especially important at high volumes or complex music arrangements, where tonal precision and clarity are crucial.
