Review: Protek 4K X1 (The Compact 4K Multistream Pioneer)

While the newer X2 has taken the spotlight, the Protek 4K X1 remains a significant milestone in the evolution of compact 4K Enigma2 receivers. It was one of the first models to successfully pair the high-efficiency Hisilicon chipset with a ultra-slim chassis, proving that you don’t need a massive box to achieve 15,000 DMIPS performance.

For the enigma2.net hobbyist, the X1 is remembered as the “stealth” 4K machine—a device small enough to be tucked away, yet powerful enough to handle 10-bit HDR content and multistream satellite feeds with the same fluid zapping speed as its larger successors.

1. Core Hardware: The Original Hisilicon Powerhouse

The X1 pioneered the use of the Hisilicon Hi3798MV200 chip for the Protek brand, bringing a level of stability and thermal efficiency that was previously hard to find in sub-200mm receivers.

• Processor (15,000 DMIPS): The ARM Quad-Core CPU (4x 1.6GHz) ensures that even with a heavy OpenATV or OpenPLi image, the user interface remains snappy and responsive.

• Modern Memory: Despite its age, it utilizes 1GB of DDR4 RAM, which provides better bandwidth for 4K video streams compared to older DDR3 standards.

• Flash Storage: The 8GB eMMC 5.1 Flash is generous for a single-tuner box, offering plenty of space for multiple picon sets and specialized plugins like Jedi Maker Xtream.

3. Tuner Efficiency & Multistream Capabilities

The X1 is a specialist’s tool, specifically designed for satellite purists:

• S2 Multistream: The fixed DVB-S2 tuner is highly optimized for Multistream PLP feeds. It is exceptionally reliable for pulling in Italian (RAI/Mediaset) and French (TNT) packages on 5.0°W without requiring specialized drivers or manual PID entry.

• Reception Stability: DXers have noted that the X1’s tuner sensitivity is remarkably high for such a small unit, maintaining a stable lock on signals that often cause “tuner failed” errors on older MIPS-based hardware.

4. Design & Connectivity Highlights

The X1 features a slightly different layout than the later X2, which some users still prefer:

• Triple USB Array: With one USB 3.0 on the rear and two USB 2.0 ports on the side, the X1 offers more peripheral connectivity than many newer “Mini” models.

• Optical Audio: Unlike the X2 which moved toward AV-jack solutions, the X1 features a dedicated SPDIF Optical output, making it easier to integrate into high-end home theater setups using older Toslink cables.

• Dual WiFi Antennas: The X1 includes integrated 2.4G WLAN with two external antenna ports (antennas included), providing a more stable wireless connection for IPTV and streaming than internal-only solutions.

Final Verdict: The Reliable 4K Compact

The Protek 4K X1 is a testament to the “if it isn’t broken, don’t fix it” philosophy. While it lacks the dual-tuner or combo options of the X2, as a dedicated 4K satellite receiver, it is arguably more flexible due to its extra USB ports and optical audio out. For the enigma2.net user looking for a secondary room box or a high-performance travel receiver, the Protek 4K X1 remains a fast, stable, and highly capable choice.
