The Iridium GZIA 135.4 is a 4-channel power amplifier that features Class AB technology. This technology provides high output power with excellent sound quality. Specifically, the amplifier delivers up to 4x 100 watts RMS at an impedance of 4 ohms, and even 4x 140 watts RMS at 2 ohms. If needed, you can also operate it in bridged mode to achieve up to 2x 280 watts RMS. The frequency response of 8 Hz to 28 kHz ensures that both low and high frequencies are covered.
The variable active crossover of the Iridium GZIA 135.4 from Ground Zero is an important feature that gives you the ability to control the frequencies precisely. This function allows you to adjust the amplifier exactly to your needs by variably shaping the transition between high, low, and mid frequencies depending on the speaker configuration. Additionally, there is a bass boost that allows you to enhance the bass reproduction, creating a powerful sound experience. With the active crossover, you specifically control which frequencies are sent to the speakers.
The stable power supply of the Iridium GZIA 135.4 is essential for its constant power output. A stable power supply ensures that the amplifier operates efficiently even at high volumes and can deliver output power without distortion. Especially at 2 ohms, where the amplifier delivers 4x 140 watts RMS, a reliable power supply is crucial. The stable energy supply prevents interruptions and maintains sound quality even during intense music use. Therefore, the power supply is an important guarantee for consistent performance.
The high-level input of the Iridium GZIA 135.4 is ideal, especially if you want to connect it to an original car radio without a preamp output. The auto-on feature allows the amplifier to automatically detect when a signal is present and turn on. This is particularly convenient, as you do not have to intervene manually. The high-level input also ensures easy installation without additional adapters, making integration into existing systems straightforward, even if the vehicle is still equipped with factory speakers.
The remote control for the Iridium GZIA 135.4 makes it easy to control the amplifier directly from your seat. With it, you can conveniently adjust important parameters such as volume, balance, fader, and other settings. However, the exact charging process of the remote control is not specified in the product description. Usually, a battery is required for power, which needs to be replaced when necessary. This feature is ideal for those who want to make sound control flexible without being physically close to the amplifier itself.
The Iridium GZIA 135.4 has compact dimensions of 168 x 49 x 278 mm, making it flexible for installation in different types of vehicles. When installing, you need to ensure that there is enough space for ventilation so that the heat sink can operate efficiently. The dimensions allow for discreet placement in the trunk or under a seat, but keep in mind the heat dissipation. It is also important to mount the connections in an easily accessible location to facilitate cable services and make any necessary adjustments.
The black anodized heat sink of the Iridium GZIA 135.4 is not only a design feature with the Ground Zero logo, but also crucial for the thermal performance of the amplifier. It ensures that the heat generated during operation is effectively dissipated, which increases the stability and lifespan of the amplifier. The anodization also protects against corrosion and gives the device an appealing, robust appearance. Especially during longer listening sessions, efficient cooling is important to protect the amplifier from overheating.
Generously sized connections significantly facilitate the installation and operation of the Iridium GZIA 135.4. They not only allow for easy connection with speaker cables of larger cross-sections but also provide secure hold and minimal resistance at the connection points. These connections significantly support signal stability and reduce losses. The easy access and clear markings greatly simplify the connection process, which is particularly advantageous when installations need to be carried out regularly or in confined spaces.
The extended frequency response of the Iridium GZIA 135.4, ranging from 8 Hz to 28 kHz, offers a wide acoustic spectrum that covers both deep bass and clear highs. This allows the amplifier to reproduce a detailed sound that is very close to the original tone. This bandwidth is particularly relevant for music enthusiasts who have high demands for sound fidelity. Low frequencies below 20 Hz are palpable, giving depth to the bass, while frequencies above 20 kHz ensure a brilliant and vibrant sound image.
The Iridium GZIA 135.4 from Ground Zero utilizes Class AB technology to provide an excellent combination of efficiency and sound quality. This technology reduces distortion and combines the advantages of Class A and Class B by amplifying audio signals with low distortion while maintaining a high efficiency. The result is an amplifier that delivers clear, uncolored audio signals while efficiently managing the supplied energy. This technology is essential for music lovers who have the highest demands on sound reproduction.
