Frequently Asked Questions about SPL Show SP 1.900

How much power does the Hertz SPL Show SP 1.900 provide at different resistances?

The Hertz SPL Show SP 1.900 Mono Amplifier offers a rated power of 1000 W at 1 Ω resistance, making it extremely powerful. At a resistance of 2 Ω, the power remains constant at 1000 W. Interestingly, the power decreases to 600 W when the amplifier is connected to a resistance of 4 Ω. The total rated power at a supply voltage of 14.4 VDC and a distortion of 1% is also 1000 W. These power specifications are remarkable for an amplifier of this compact size and provide flexibility when tuning with various speaker setups.

What size is the SPL Show SP 1.900 and how does it affect installation?

The Hertz SPL Show SP 1.900 has an ultra-compact size of only 211.6 x 130 x 49 mm. This compact design allows for easy installation even in tight spaces, which is particularly advantageous in modern vehicles. However, the small size requires thoughtful integration into the existing audio setup. You should ensure that there is adequate ventilation to maintain operating temperatures in the range of 0 °C to 55 °C. Installation can be facilitated by the IP55 protection class, as it provides additional protection against dust and water.

What filter options does the Hertz Amplifier SPL Show SP 1.900 offer?

The Hertz SPL Show SP 1.900 offers an impressive variety of filter options to optimally adjust the sound. These include a low-pass filter with an adjustable frequency of 50 to 250 Hz at 24 dB/oct. Additionally, there is a bass boost at 45 Hz that can be set between 0 and 8 dB to enhance the bass according to individual preferences. The phase can be precisely adjusted between 0 and 180°. Another noteworthy filter is the subsonic filter at 25 Hz, also with 24 dB/oct., which can filter out unwanted lower frequencies.

What is the efficiency of the SPL Show SP 1.900?

The Hertz SPL Show SP 1.900 Amplifier features its Advanced D-Class (ADC) output stage, achieving a remarkable efficiency of up to 87%. This high efficiency means that the amplifier generates less heat and thus has a lower energy balance. This is especially important if you want to operate the amplifier in a vehicle, as it reduces the electrical load on the vehicle and guarantees more stable performance. Such a high efficiency in an amplifier of its class is a significant advantage over other models.

What is the minimum possible load impedance for the Hertz SP 1.900?

The Hertz SPL Show SP 1.900 Amplifier allows for a minimum load impedance of 1 Ω. This opens up the possibility of achieving extremely high output power, particularly resulting in high performance and volume. The ability to operate with such a low impedance allows you to combine the amplifier with multiple subwoofers that are connected in parallel. With a load impedance of 1 Ω, you can fully utilize the maximum capacity of 1000 W, making it ideal for demanding car audio systems designed for intense bass reproduction.

What supply voltage does the SPL Show SP 1.900 require?

The SPL Show SP 1.900 Amplifier from Hertz requires a nominal supply voltage in the range of 11 to 15 VDC. At the same time, it is designed for pulse operation with a voltage of 6 to 16 VDC, which means it remains stable even with voltage fluctuations in your vehicle's power supply. The idle current is 1.1 A, while the idle current in the off state is only 0.03 mA, making it very energy-efficient. These voltage ranges are typical for automotive applications and ensure reliable power delivery, even under adverse conditions.

How is the remote activation of the SP 1.900 Amplifier done?

The remote activation of the SPL Show SP 1.900 is done via the SPK from DC-OUTPUT BTL speakers in the range of 3.5 to 7 VDC. This type of remote activation is particularly useful for conveniently controlling the amplifier without needing direct access to the control devices. It allows you to automatically turn on the amplifier when the car's audio system is activated. Furthermore, the remote input for activation requires a voltage of about 6 to 15 VDC with a current consumption of 9 mA, thus maintaining manageable energy requirements.

What protection mechanisms does the Hertz SPL Show SP 1.900 have?

The Hertz SPL Show SP 1.900 Amplifier is equipped with an IP55 protection rating, which guarantees significant resistance against dust and water. This makes it ideal for use in vehicles, where such conditions are common. The robust design ensures that the amplifier remains reliable even under harsh conditions. If you live in an area with high humidity or many off-road activities, this protection offers additional security that your amplifier will not be affected by external environmental influences. Additionally, the protection rating allows for more flexibility in placement within the car.

What is the signal-to-noise ratio of the SP 1.900?

The Hertz SPL Show SP 1.900 features a signal-to-noise ratio of 95 dBA (A-weighted at 1 V input). This ensures clear and low-noise audio playback, which is especially important when you want to listen to music at high volume. A high signal-to-noise ratio means that distracting background noise is minimized, allowing for music playback in pure, unadulterated quality. Whether in the highs, mids, or lows, the SP 1.900 ensures that audio playback remains clean and crisp, enhancing your overall sound experience.

Can the Hertz Amplifier SP 1.900 be used with different speakers?

The Hertz Amplifier SP 1.900 offers you high flexibility in speaker selection through its preamp and speaker sensitivity. The preamp sensitivity ranges from 0.6 to 6 VRMS, while the speaker sensitivity covers a range from 2.2 to 22 VRMS. This wide sensitivity range allows the amplifier to be matched with a variety of speaker types and configurations, making it ideal for demanding car audio installations. It can thus be integrated with both OEM systems and high-quality aftermarket speakers to meet different sound requirements.
