Frequently Asked Questions about Bravo HQ 800.4

What power does the Stetsom Bravo HQ 800.4 Amplifier provide at 12.6 V?

The Stetsom Bravo HQ 800.4 delivers an impressive power of 4 x 200 Watts RMS at 2 Ohm when operating at a voltage of 12.6 V, which is ideal for powerful car audio installations. If you use additional speakers with 4 Ohm resistance, the amplifier provides a power of 4 x 130 Watts RMS. Furthermore, the bridging mode allows for an even higher output power of 2 x 400 Watts RMS at 4 Ohm. This allows for versatile adjustments for different speaker configurations in your vehicle and ensures powerful sound experiences on every drive.

What power can the Bravo HQ 800.4 achieve at 14.4 V?

At a supply voltage of 14.4 V, the Stetsom Bravo HQ 800.4 shows its maximum performance with an output power of 4 x 250 Watts RMS at 2 Ohm, which provides significantly more power for fast, powerful sounds. At 4 Ohm resistance, the power is 4 x 170 Watts RMS, and this difference in voltage is often observed in more modern vehicles. This allows the amplifier to reach its full potential, making it particularly suitable for the strongest and most energetic audio deliveries in a car audio system.

What is the frequency range of the Stetsom Bravo HQ 800.4?

The Stetsom Bravo HQ 800.4 covers an impressive frequency range of 5 Hz to 22 kHz, allowing you to reproduce both deep bass and high frequencies clearly and in detail. This comprehensive range makes the amplifier compatible with a variety of different speaker types, from Subwoofer to Tweeter, enabling a custom fit to your preferred sound profile. A wide frequency response is crucial for audiophiles to experience all facets of music without loss or distortion.

What is the signal-to-noise ratio of the Bravo HQ 800.4?

The signal-to-noise ratio of the Stetsom Bravo HQ 800.4 is over 80 dB. This means that the amplifier is capable of reproducing audio signals with minimal background noise, which is particularly beneficial during quiet passages of your music. A higher signal-to-noise ratio ensures clear, precise playback and avoids disturbing background noise when you increase the volume or with differentiated sound profiles like classical music or jazz. You will be able to hear the fine details and nuances of the music more clearly.

What crossover functions does the Bravo HQ 800.4 offer?

The Bravo HQ 800.4 is equipped with flexible high pass and low pass crossover functions that provide a variable frequency range from 50 Hz to 2.3 kHz. These crossover settings allow you to precisely adjust the frequencies that are passed to your speakers, minimizing distortion and optimizing sound quality. In particular, bass can be accurately directed to the Subwoofer and higher frequencies to the Tweeter, ensuring a balanced sound reproduction in your car, regardless of the audio source or music genre you are playing.

How large is the Stetsom Bravo HQ 800.4 and what does that mean for installation?

The Stetsom Bravo HQ 800.4 has dimensions of 167 mm in width, 235.5 mm in length, and 58.5 mm in height.
