Ground Zero GZIA 4.120 Amplifier
The Ground Zero GZIA 4.120 is a 4-channel amplifier for high-quality audio performance. It utilizes Class A/B technology to deliver clear and powerful sound. This amplifier is suitable for enhancing car audio systems with reliable power output.
High-Quality Class A/B Amplifier
The GZIA 4.120 employs Class A/B technology, balancing efficiency and audio fidelity. This design ensures minimal distortion, providing listeners with clear and accurate sound reproduction. The amplifier's stable power supply supports consistent performance across various audio setups. Its black anodized heatsink aids in effective heat dissipation, maintaining optimal operating temperatures. This construction enhances the amplifier's durability and longevity.
Versatile 4-Channel Configuration
Equipped with four channels, the GZIA 4.120 offers flexibility in audio system design. It delivers 4x 70 Watts RMS at 4 ohms and 4x 120 Watts RMS at 2 ohms, accommodating different speaker configurations. The amplifier can operate in bridged mode, providing 2x 240 Watts RMS at 4 ohms for higher power needs. This versatility makes it suitable for driving multiple speakers or subwoofers. The large terminals facilitate secure and efficient connections.
Integrated Active Crossover and Bass Boost
The GZIA 4.120 features a variable active crossover, allowing users to adjust frequency settings for optimal speaker performance. The high-pass filter ranges from 40 Hz to 3000 Hz, while the low-pass filter covers 30 Hz to 250 Hz, with a 12 dB/octave slope. Additionally, the amplifier includes a bass boost function to enhance low-frequency output. These features enable customization of the audio output to match listener preferences. The adjustable input sensitivity (200 mV – 6 V) ensures compatibility with various head units.
High-Level Input with Auto-On Function
The amplifier features an auto-on function on its high-level input, simplifying integration with factory head units that lack dedicated preamp outputs. This feature detects incoming audio signals and powers on the amplifier automatically, eliminating the need for a separate remote turn-on wire. This design facilitates easier installation on a broader range of vehicles. The auto-on function enhances user convenience by streamlining the setup process. This integration capability makes the GZIA 4.120 versatile for various car audio installations.

| General Specifications | |
Frequency Response Frequency Response in a car amplifier refers to the range of audio frequencies it can amplify, typically measured in Hz. For example, a response of 20Hz to 20kHz indicates the amp can handle deep bass to high treble, covering the full audible spectrum.
|
|
S/N Ratio S/N Ratio (Signal-to-Noise Ratio): A measure of an amplifier's ability to amplify audio signals relative to background noise. A higher S/N ratio indicates clearer sound, as more of the output is dedicated to the signal rather than noise.
|
|
THD+N @ Rated Power THD+N (Total Harmonic Distortion plus Noise): A measurement of the total distortion and noise introduced by an amplifier. Lower values indicate cleaner audio reproduction, as less distortion and noise affect the output signal.
|
|
Input Voltage Range Input Voltage Range: The range of voltage levels an amplifier can accept from the audio source. It determines compatibility with various head units or signal processors, ensuring optimal signal strength without distortion or clipping.
|
|
Low Pass Filter Low Pass Filter: A feature that allows only frequencies below a specified cutoff point to pass through to the subwoofer, blocking higher frequencies to ensure cleaner bass output.
|
|
Crossover Slope Crossover Slope: The rate at which frequencies are attenuated beyond the crossover point, measured in dB per octave. Steeper slopes (e.g., 24 dB/octave) provide more precise separation between frequency ranges, improving sound clarity.
|
|
Fuse Rating Fuse Rating: The maximum current an amplifier can handle before its fuse blows, protecting the unit from damage. It indicates the amp’s power capacity and helps ensure safe operation within the electrical system.
