Frequently Asked Questions about Opus I

What output power does the Quartorigo Opus I 2-Channel Amplifier offer?

The Opus I, a 2-Channel Amplifier from Quartorigo, provides an output power of 100 W x 2 in Stereo HD mode at 4 Ω. If you use it at 2 Ω, the power increases to 190 W x 2. In Mono HD operation, the device shows its power with 380 W x 1 at 4 Ω and an impressive 595 W x 1 at 2 Ω. These power values demonstrate the wide range of applications of the amplifier and allow for adaptation to different speaker systems, providing diverse possibilities in audio setups. Especially at high volumes, you can enjoy the full sound.

What frequencies does the Quartorigo Opus I Amplifier cover?

The frequency response of the Quartorigo Opus I ranges from 8 Hz to 50,000 Hz, covering the entire spectrum of human audible tones. This wide coverage ensures that both deep, booming bass and the finest, clear highs are reproduced accurately. Whether you are listening to classical music with subtle highs or electronic tracks with deep bass, this amplifier provides an immersive sound experience. Particularly noteworthy is its ability to handle very low frequencies, which contributes to a rich, full-bodied sound.

What is the input impedance of the Opus I Amplifier?

The input impedance of the Quartorigo Opus I is 48 kΩ. This high impedance reduces the risk of signal distortion and allows for the processing of input signals with a range of 0.4–8 V. One advantage of this value is the increased flexibility, as the amplifier works well with both low-level pre-outs and high-level signals. This means for you as a user that the source can vary without compromising sound quality. Another benefit is the ability to minimize noise and interference.

How strong is the signal-to-noise ratio of the Opus I Amplifier?

The signal-to-noise ratio of the Opus I Amplifier from Quartorigo is over 100 dB. Such a high value indicates how quiet background noises are compared to the actual signal. This means that you can listen to music in its purest form, without additional, unwanted noises. The higher the SNR value, the cleaner the signal compared to an amplifier with a lower ratio. This ensures that you receive clear and interference-free audio output, especially at low volumes.

What dimensions should I consider when installing the Opus I from Quartorigo?

When installing the Opus I, you should consider the dimensions of 433 x 238 x 54 mm. This size is crucial for placement in your vehicle's interior. In case of space constraints, it helps to check the measurements beforehand to ensure that the amplifier can be comfortably accommodated. This guarantees an easy, smooth installation process and optimal performance. Despite its compact size, the Opus I offers immense power, making it ideal for cars with limited space. Make sure that ventilation is not obstructed to avoid overheating.

What is the standby power consumption of the Quartorigo Opus I?

The standby power consumption of the Quartorigo Opus I is over 6 A. This value indicates how much power the amplifier requires in standby mode when it is not actively used. Although this consumption in standby mode is not insignificant, you should ensure to turn off the system completely during prolonged periods of non-use to avoid unnecessary electricity costs. This is especially important in vehicles to preserve the battery. Despite the high standby consumption, the amplifier impresses with its performance, justifying the energy expenditure.

How does the input sensitivity of the Opus I Amplifier affect the sound?

The input sensitivity of the Quartorigo Opus I ranges from 0.4 to 8 V, allowing for flexible adjustment to a variety of signal sources. This is crucial to ensure that the amplifier correctly and optimally amplifies the input signal. A low sensitivity requires stronger signals, while higher sensitivities respond more sensitively to weak signals. This flexibility allows you to use a variety of sources without compromising sound quality and contributes to optimizing overall performance, whether working with strong or weak signals.

How do I optimally install the Opus I amplifier in the car?

For optimal installation of the Opus I in the car, note the dimensions of 433 x 238 x 54 mm. Place it in a ventilated area to avoid overheating. The location should be dry and free from mechanical vibrations. Ensure that the power supply provides a minimum of 10V to ensure efficient operation. Also, ensure that access to the connection terminals is easily available for simple maintenance. Ultimately, proper wiring ensures maximum sound enjoyment, especially if you prefer high volumes.

What voltage is the Quartorigo Opus I designed for?

The Opus I from Quartorigo is designed for a power supply of 10 to 14.4 Vdc. This is crucial for operation in a vehicle context, as it is compatible with common battery systems. A constant voltage within this range ensures that the amplifier operates efficiently and the output power remains stable. What you should pay attention to with this base is to avoid fluctuations to ensure optimal system performance, providing you with a consistently high-quality sound experience.

What is the weight of the Quartorigo Opus I amplifier?

With a weight of 7.7 kg, the Quartorigo Opus I is a portable amplifier that promises stability and robustness. The weight plays a significant role in placement within the vehicle to avoid disturbing the balance and increasing safety. This weight also indicates a high-quality construction that enables the amplifier to operate without unwanted vibrations or movements even at high volumes. A custom installation ensures that the weight does not negatively impact driving behavior.

Es lohnt sich!

Ich habe sie an den Sounddigital 800.4 Evo6 angeschlossen. Und ich bin mehr als zufrieden. Mitteltöner laut und auch präzise. Hochtöner brennen nicht in den Ohren, die sind laut und geben das, was sie sollen. Gut angelegtes Geld.

Laut ... einfach nur laut

Also ich sag es mal so... wenn man ein Lautes Kompo System sucht, mit noch sehr guten Klangeigenschaften.
Naja der sollte das T3 von Rockford nehmen.
Ich hatte viele Systeme verbaut und bin dann wieder zurück zum T3 und habe nun 3 verbaut... schön laut und sehr feiner Klang.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.
