What are the power specifications of the SN A 1.8 at different impedances?

The SN A 1.8 Amplifier from SUB19 offers impressive power specifications. At an impedance of 1 Ω, it delivers up to 2000 W RMS with a total harmonic distortion (THD+N) of 5% and 1800 W at 1% THD+N. At 2 Ω, you get 1350 W at 5% THD+N and 1160 W at 1% THD+N. Finally, the amplifier provides 780 W at 5% THD+N and 660 W at 1% THD+N for an impedance of 4 Ω. This shows that the SN A 1.8 covers different power strengths and can adapt depending on sound requirements, making it an ideal choice for various use cases.

What frequency response options does the SN A 1.8 Amplifier offer?

The SUB19 SN A 1.8 is known for its excellent frequency coverage. It offers a frequency response range between 18 Hz and 175 Hz at -1 dB and an extended range of 13 Hz to 225 Hz at -3 dB. This allows you to reproduce low frequencies with remarkable precision and clarity. The amplifier is excellent for demanding bass applications and is particularly beneficial if you prefer music styles that require strong, deep bass. The frequency ranges of the SN A 1.8 are ideal for reproducing and emphasizing low-frequency music passages through high-quality Subwoofers.

How does the bass boost of the SN A 1.8 work?

The SN A 1.8 from SUB19 is equipped with an adjustable bass boost that can be set between 30 Hz and 80 Hz. The gain ranges from 0 dB to 12 dB, allowing you to adjust the bass to your preferences. The fine-tuning of the quality factor enables precise control to further personalize the frequency response and bass adjustment. This allows you to optimally adapt low-frequency sounds to your environment and preferred listening habits, which is especially advantageous if you value intense and rich bass. This feature offers maximum flexibility for ultimate bass enjoyment.

What filters does the SN A 1.8 offer?

The SUB19 SN A 1.8 Amplifier features precisely adjustable filter technologies. The low-pass filter can be freely selected from 35 Hz to 225 Hz with a slope of 24 dB/octave, allowing you to efficiently eliminate unwanted high frequencies. Additionally, the high-pass filter is adjustable from 14 Hz to 60 Hz, also with a slope of 24 dB/octave, to control low frequencies and optimize sound. These filters enable fine-tuning of audio performance, so your speakers and your Subwoofer can operate in their optimal frequency ranges. These specific filter settings support the excellent sound quality of the device.

How large is the SN A 1.8 and how does it fit in common vehicles?

The SN A 1.8 from SUB19 has dimensions of 228 mm in width, 53 mm in height, and 393 mm in length. These compact measurements allow for easy integration of the 1-channel Amplifier into a variety of vehicle models, regardless of brand or model, as long as the available space is sufficient for these specifications. The core requirement is to check the exact installation conditions, both in terms of available engine bay or trunk capacity, as well as regarding ventilation to avoid thermal stress, ensuring the longevity and optimal performance of the Amplifier and ensuring trouble-free operation.

What efficiency does the SN A 1.8 offer at THD+N = 1 %?

At an impedance of 4 Ω, the SUB19 SN A 1.8 offers a remarkable efficiency of 89.6 % under the condition that the total harmonic distortion plus noise (THD+N) is at 1 %. Such high efficiency means that the Amplifier converts energy very effectively, which not only maximizes performance under optimal conditions but also minimizes heat loss. This feature is essential for users who want to operate their Amplifier for long periods without significant energy losses. The high efficiency thus significantly contributes to sustainable and powerful audio playback.

What input sensitivity does the SN A 1.8 support?

The SUB19 SN A 1.8 Amplifier can process signal inputs in a range from 0.2 V to 5 V. This means that the device is compatible with a variety of audio devices, as it can operate with both high-level and low-level signal sources. The wide input sensitivity range allows for seamless integration into different car audio systems, regardless of their output values, to ensure optimal sound quality. This way, you can easily incorporate the amplifier into existing systems without having to make extensive changes to the signal source.

Why is the clipping indicator important on the SN A 1.8?

The clipping indicator of the SN A 1.8 from SUB19 is a significant feature as it helps the user identify and avoid distortions in the output. Once the input signal exceeds the maximum processable level, the clipping LED lights up. This ensures that the user has the opportunity to reduce the level in time to minimize the distortions that can occur from overdriving. Combined with the switchable clip limiter, this system provides clean and clear sound without audible distortions. This feature is particularly useful when high volume levels are involved.

What operating voltage range does the SN A 1.8 cover?

The SN A 1.8 Amplifier from SUB19 supports an operating voltage range of 8.6 V to 16.2 V. This voltage flexibility allows for use in vehicles with different electrical systems, whether vehicles with 12 V onboard network configurations or those that may have varying voltage fluctuations. This wide range ensures that the amplifier remains stable even during voltage drops that may occur during operation. Thus, it is ensured that there is no loss of sound or power drops even with fluctuating onboard voltage in the vehicle. This voltage adaptability is essential for use in varying environments and conditions.

What is the signal-to-noise ratio (SNR) of the SN A 1.8?

The SN A 1.8 from SUB19 has a signal-to-noise ratio (SNR) of over 75 dB. A high SNR is crucial to ensure that the useful signal is transmitted without interference from background noise, which guarantees clear and detailed audio output. This is particularly important in acoustic applications where high sound quality is a priority. Especially with detailed music or subtle sound nuances, the listener benefits from this high SNR, as only minimal interauditory disturbances occur, preserving the finesse and integrity of the audio representation.

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
