LEYE-DH350 Professional Audio Amplifier FAQ – Frequently Asked Questions

What is the power output of DH350? Does it support bridged mode?

2×350W/8Ω (2×530W at 4Ω), bridged 1050W mode—Class D efficient drive for powerful cinema/entertainment speakers.

(LeyeDisplay)

What is the distortion and signal-to-noise ratio of this amplifier? Is the sound quality pure?

THD ≤0.03%, SNR ≥105dB, 20Hz-20kHz ±0.5dB response for pure, noise-free sound—resolves distortion pains.

What is the power consumption and efficiency of LEYE-DH350? Is it suitable for long-term use?

Low static power high dynamic energy, slew rate 15V/µS, damping factor >240—suits 24/7 operation, resolves high consumption pains.

Will it get very hot or noisy when pushed hard? Is the fan loud?

Almost silent, stays cool like AC! Ultra-efficient Class D + intelligent temperature-controlled cooling — even at full 350W×2 load, case stays ~38℃. Fan uses 3-stage smart speed control (near-stop at low load). You can’t hear it from 1 meter away — completely ends the nightmare of “sounds like a jet engine and too hot to touch”!

Is LEYE-DH350 easy to install? Is it rack-compatible?

Yes, 1U rackmount design (483×235×45.5mm), quick XLR/RCA wiring, 3.52kg lightweight—easy for desktop/rack integration.

What protection mechanisms does LEYE-DH350 have? Does it prevent overheating/overload?

Soft start, undervoltage/overvoltage, overheating, overload/overcurrent, DC protection—auto-detects and responds to prevent damage, solves inadequate safeguarding pains.

Can it drive both my 8Ω and 4Ω speakers? What if it can’t push them hard enough?

Eats 8Ω and 4Ω for breakfast! 350W×2 at 8Ω, instantly 530W×2 at 4Ω, bridged up to 1050W. Damping factor >240 — drives everything from bookshelf speakers to 18″ subs full, relaxed, and hard. No more worries about “weak sound, no bass, can’t drive”!

Which application scenarios is LEYE-DH350 best suited for?

Designed for cinemas, multi-purpose halls, entertainment venues, and high-end home Hi-Fi. High dynamic energy ensures immersive audio.
