ZLOC4.4
The ZLOC4.4 is designed to enhance your vehicle's audio system. Many vehicles come with integrated amplifiers, but the original OEM setup often falls short on performance.
The ZLOC4.4 bridges the gap between OEM systems and aftermarket audio components. It addresses the limitations of factory-installed audio by bypassing OEM resistance and eliminating unwanted system noise, enabling improved audio performance without altering your vehicle's factory settings.
The ZLOC4.4 operates via four high-level inputs, switchable between 2CH and 4CH input modes, which capture speaker signals from your OEM head unit or amplifier and feed them to four low-level outputs. This is the core function of the ZLOC4.4, allowing you to expand your existing audio setup.
A notable feature of the ZLOC4.4 is its built-in CLIP indicator. This monitors input and output signals continuously for any sign of distortion, giving you a clear indication when signal levels need adjusting.
The ZLOC4.4 also removes the need to replace your factory head unit, eliminating the restrictions that can otherwise limit audio upgrades. It integrates aftermarket components into your OEM setup cleanly, improving overall sound quality and bass performance.
The ZLOC4.4 is a cost-effective way to improve your audio system's performance within an OEM integration setup. It works well alongside amplifiers such as the Phoenix Gold ZDA4.8 4-Channel DSP Amplifier for a complete system upgrade.
Bass CUBE
The Phoenix Gold Bass CUBE is built directly into the ZLOC4.4. It lets you fine-tune the bass level by selecting a centre frequency between 20Hz and 110Hz, adjusting output between -9dB and +9dB, with a variable Q value.

Frequently Asked Questions
Q: Will an amplifier work with my factory head unit?
A: Yes, in most cases. If your head unit has no RCA outputs you will need a line output converter to feed the amplifier a clean signal. CEN stocks line output converters and can advise the right one for your vehicle.
Q: What does the ZLOC4.4 do?
A: It converts 4 channels of speaker-level signal from a factory head unit or amplifier into 4 low-level outputs, so you can add aftermarket amplifiers while keeping the factory system.
Q: Does the ZLOC4.4 have bass control?
A: Yes. The built-in Bass CUBE lets you choose a centre frequency between 20Hz and 110Hz and set the level between -9dB and +9dB, with a variable Q value.
Q: How does the ZLOC4.4 switch on?
A: Turn-on can be triggered by REM, DC offset or audio signal, and it has both REM in and REM out connections.
Q: Can CEN fit the ZLOC4.4?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
