In 4-channel operation, the amplifier delivers 160W x 4 at 4Ω and 250W x 4 at 2Ω. The 3-channel operation combines two channels with 160W at 4Ω and one channel with 500W at 4Ω or 250W x 2 at 2Ω plus 500W x 1 at 4Ω. In 2-channel mode, 500W x 2 at 4Ω is possible. This versatility allows for adjustments to different audio system requirements in vehicles.

What advantages does the IP55 aluminum housing of the SPL Show SP 4.900 offer?

The IP55 aluminum housing of the SPL Show SP 4.900 from Hertz provides high protection against dust and water. This makes the amplifier particularly robust and durable, even under challenging operating conditions. The resilient housing allows for operation without additional cooling from fans, which simplifies installation and minimizes noise. Additionally, the power cables, inputs, and outputs are sealed, protecting them from oxidation. This combination of protection and convenience ensures stable performance of the amplifier over long periods, even in harsh environments.

What is the efficiency of the SPL Show SP 4.900 amplifier?

The SPL Show SP 4.900 amplifier from Hertz achieves an impressive efficiency of 85%. This means that a large portion of the supplied energy is converted into output power, which is efficient and minimizes heat generation. The efficient use of energy helps ensure that the amplifier requires less power and conserves the vehicle's battery. Especially in power-intensive audio systems, high efficiency is crucial for maximizing sound quality and minimizing energy losses, which speaks to the amplifier's performance.

How is the calibration of the SPL Show SP 4.900 amplifier performed?

Calibrating the SPL Show SP 4.900 from Hertz is easy thanks to the centrally arranged crossover filters and controls. The amplifier offers adjustable crossovers for precise sound adjustment. The crossovers include Hi-Pass and Lo-Pass filters from 50 Hz to 5 kHz at 12 dB/Octave. These filters allow settings that tailor the performance to the specific arrangement of the speakers. Additionally, the Bass Boost at 45 Hz provides another way to adjust the sound according to personal preferences, making the amplifier suitable for individual sound profiles.

What is the signal-to-noise ratio of the SPL Show SP 4.900?

The SPL Show SP 4.900 achieves an excellent signal-to-noise ratio (SNR) of 105 dBA, A-weighted at 1 V input. This high SNR indicates that the amplifier is capable of transmitting clear audio signals with minimal noise, which is crucial for a precise and pure listening experience. Especially when playing music at high volumes, a high SNR is important to minimize distortion and maximize sound quality. The signal-to-noise ratio is an important parameter that underscores the technical superiority of the amplifier.

What are the dimensions of the SPL Show SP 4.900?

The dimensions of the SPL Show SP 4.900 are compact, measuring 211.6 mm in length, 130 mm in width, and 49 mm in height. These ultra-compact measurements allow for easy installation in vehicles, even in limited space. Weighing 2.15 kg further facilitates mounting. Due to its small size and light weight, this amplifier fits excellently into various vehicle applications. This compactness, combined with the robust aluminum casing, makes the amplifier flexible and user-friendly for many installation scenarios.

What are the operating requirements of the SPL Show SP 4.900 regarding power supply?

The SPL Show SP 4.900 requires a nominal voltage of 11 to 15 VDC, making it suitable for operation in most vehicle power systems. The pulse operating voltage ranges from 6 to 16 VDC. The idle current is 1.1A and in the off state, it is 0.03 mA. The maximum current draw at minimum load impedance (maximum musical power) is 50A. These requirements are important to note to ensure the maximum performance and efficiency of the amplifier and to avoid overloading the vehicle system.

What load impedance can the SPL Show SP 4.900 handle?

The SPL Show SP 4.900 is flexible regarding the minimum load impedance it can handle. In 4-channel operation, the minimum load impedance is 2Ω. In 3-channel operation, you can configure 2Ω + 2Ω + 4Ω, and in 2-channel mode, it can handle a load of 4Ω. This flexibility is advantageous for installation in many different speaker systems, as it allows for adaptation to various speaker configurations. The ability to handle low impedances contributes to the overall performance of the amplifier and increases its versatility in use.

How does the bass boost function of the SPL Show SP 4.900 affect sound quality?

The bass boost function of the SPL Show SP 4.900 is adjustable at 45 Hz and allows for an increase in the range of 0 to 8 dB. This function enhances the low frequencies and provides the option to adjust the bass according to individual preferences. This is particularly useful when you listen to music genres that require strong bass reproduction. Through the adaptability of the bass boost, you can find the balance between other sound frequencies and the bass, resulting in the amplifier providing a rich and dynamic sound profile. It highlights the versatility of the device.

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.
