Stop Fighting the Audio Panel. Start Hearing The Alerts.
Installing modern safety tech shouldn't require a $5,000 "center stack" surgery. Holy Micro’s new Stack-Pass MixAmp is designed to bypass the complexities of existing audio panels, saving you thousands in installation costs while guaranteeing you never miss a critical alert.
The Problem: The "Audio Bottleneck"
Most pilots face three major hurdles when adding new gear:
1. No Room: Existing audio panels are often "maxed out" with no open ports.
2. Audio Drowning: Critical alerts get muted or overpowered by busy ATC or CTAF chatter.
3. High Risk/Cost: Opening a decades-old center stack is a "can of worms" Most technicians are hesitant to touch them, and specialized avionics shops charge premium rates just for the labor.
The Solution: The Holy Micro Independent Audio Path
Our FAA-approved aviation-grade Voice Range speaker—complete with a mixer-amp-driver board provides a dedicated, high-resolution audio environment for your Absolute AoA and SkyVoice products without ever touching your existing audio panel.
• Zero Stack Interference: No need to disturb your GPS, Transponder, or Radio wiring. If your A&P can run a power wire, they can install this system. Your primary COM and NAV audio remain untouched, giving you high-fidelity auxiliary audio without compromising your primary lifeline.
• 3-Channel Smart Mixing: Connect up to three audio sources, two wired and one Bluetooth audio. Hear your Absolute AoA tones and SkyVoice announcements mixed perfectly in real-time—a feature no other product on the market offers. Once secured behind the panel, you can easily manage pairing, mixing, and volume remotely using any smart device or the Holy Micro HMI.
• Guaranteed Audibility: Our high-grade aviation speaker is designed to penetrate even the most advanced noise-canceling headsets. Experience crystal-clear audio layering without the "mud."
• Massive Cost Savings: By simplifying the install to a basic electrical task, you save thousands in specialized avionics labor and avoid significant shop delays.
• Versatile Integration: Prefer your headset? Use the board as a "pre-mixer" to combine three signals into one single un-muted input on your existing audio panel.
The Bottom Line: You get the lifesaving safety of Absolute AoA and SkyVoice Alert with a "no-surprises" installation. It’s cleaner, louder, and significantly more affordable.
Items included: One 4inch Square aviation grade, DO-160 compliant, Flame Retardant 5 watts , 8 ohm, 90 dB SPL Voice Range speaker and one mixer & amplifier driver board with volume control.
