Your First Week With SNAIL POWER: 5 Common Questions
2026-11-13 · Company News
Service requests in the first week after installation fall into two kinds: settings that were never aligned, and real faults. The former accounts for about half — the subwoofer never paired, the surround never decoded, the microphone gain opened too far, the app on a different subnet, the left and right levels never calibrated. All five of these you can check yourself first.
Key points
- No sound from the subwoofer: look at the power light, the pairing light and the input source first.
- No surround output: walk the test tone through each speaker, and you will know whether the missing one is the source or the chain.
- Microphone howling is positive feedback; distance and lower gain will hold most of it down.
- The app will not connect: reboot the router first, then check whether the phone is on the same band.
- Left and right uneven: measure the distances before you touch the levels; break-in cannot explain an offset.
1. The subwoofer has no sound: nine times out of ten it is these three things
Symptom. Dialogue and ambience are all there, but the low end is missing; the sub's light is on and the cabinet does not move.
Cause. According to after-sales follow-ups, about 90% of these service requests come down to three things. Pairing never completed: the sub and the main unit run over a dedicated 5.8G channel, and after a move, a socket change or a power cut they have to be paired again — until they are, it is just a powered box. Power not switched on: if the outlet, the power strip or the rear-panel power button is off, the light will not come on, and some models sit in auto standby and never wake. Wrong input source: the home theater AV receiver is parked on the TV input while the player is plugged into the optical port.
30-second self-check. ① Is the power light on; ② a slowly flashing pairing light means pairing in progress, solid means connected, dark means the process never started; ③ is the input source the same one, and has the sub's volume been turned all the way down.
When after-sales service is required. The light is on, pairing is solid, the input source is correct, and the sub still makes no sound; it still will not power up on another outlet or with another cable; there is a ticking inside the sub, the light turns red, the cabinet gets hot. For the last three, do not power it up again to test.
The cost: pairing means someone crouching at the sub pressing a button and then walking back to the sofa to listen, a dozen minutes each time; in a living-room cinema the sub usually sits behind the cabinet in a corner, with the cable tight, so it often takes two people.
2. No surround: locate it with the test tone first
Symptom. The three front speakers play and the two at the back are silent; or the back ones play but smear into one mass.
Cause. Three possibilities. The source is not 5.1: old films, documentaries, and some streaming titles labelled 5.1 are really stereo upmixed. The player's output is wrong: set to PCM stereo with bitstream passthrough off, and multichannel is downmixed to two channels. The AV receiver's decoding has not been switched: fed a two-channel signal it falls back to Stereo or upmixing on its own, and the rear surrounds seem to be doing something when in fact they are only getting a share of the front channels.
30-second self-check. Call up the AV receiver's test tone (pink noise) and walk it L→C→R→SL→SR: if every one plays, the chain is fine and the problem is in the source or the decoding; if one is silent when its turn comes, check that speaker's pairing, wiring and level.
When after-sales service is required. The test tone reaches a speaker that is completely silent, while pairing is solid and that channel's level is not zero; or that cabinet has breakup or a continuous hum.
The cost: section-by-section troubleshooting takes 20–40 minutes, and you still have to try another source. Upmixing can manufacture surround, but the image drifts; some old films are only stereo and no setting will pull a rear surround out of them — that is the ceiling of the content.
3. Karaoke microphone howling: positive feedback, not a fault
Symptom. The moment you open your mouth there is a long "eeee"; move the microphone away and it stops, bring it close and it starts again.
Cause. Howling is positive feedback: the microphone picks up sound, it is amplified, it comes out of the speaker, it is picked up again — and once the gain at some frequency in that loop exceeds 1 it self-oscillates. Three things are easy to get wrong: the microphone too close to the speaker, a meter or so away and still pointed at the tweeter; the gain opened too far, microphone and main volume pushed up together; a phase problem — two microphones open at once and close together, the two paths summing so that some frequency sings more easily.
30-second self-check. Take the microphone 1.5–2m from the speaker and stand 30–45° off to the side, not on the speaker's front axis; cut the microphone gain only, and once it stops howling leave 3dB of margin in hand; use the two microphones alternately.
When after-sales service is required. It still howls with the gain pressed very low; it still howls after changing the microphone, the position and the speaker; only one particular cabinet howls — that one's driver, wiring or mounting angle needs a person to look at it.
The cost: bring the gain down and the vocal thins out and the dynamics get squashed, which makes singing hard work; high SPL plus a microphone in a small room is a physical conflict, and adjustment can only soften it.
4. The app will not connect: first check whether you are on the same subnet
Symptom. The app shows "device not found", or spins indefinitely; sometimes it connects, and tapping play does nothing.
Cause. Not being on the same WiFi is the most common: a router with band steering puts the phone on 5G while the device stays on 2.4G, the two sides are separated and cannot see each other; the guest network has AP isolation on by default, and the same applies. Next, the device is not powered: main unit off, network cable not plugged in. Third, the app version is old.
30-second self-check. Is the phone on the same WiFi as the device; is the device's power light solid; has the app been updated. If all that is fine, reboot the router: power off for 30 seconds, power back on, wait two minutes, forget the network on the phone and reconnect.
When after-sales service is required. Same subnet, latest app, router rebooted, and it still cannot be found; the device is discovered but does not respond to control; another phone gives the same result.
The cost: going into the router's admin page to split the two bands and turn off AP isolation is a hurdle for a good many people; rebooting the router cuts the internet for the whole household, so you have to pick a time.
5. One side louder than the other: measure distance first, then adjust level
Symptom. At the sweet spot the left sounds louder and the vocal leans to one side; or one cabinet sounds dull and the other bright.
Cause. Placement asymmetry: the differences in distance from the left and right speakers to the ears, to the side walls and to the rear wall, and for in-ceiling units the difference in cut-out positions. Room reflections: glass, tile and bare wall on one side against a fabric sofa, heavy curtains and a bookshelf on the other; reflected sound between 200Hz–2kHz can sum by several dB. Driver not broken in: new surrounds are stiff and the sound changes over the first 20–50 hours, usually on the order of 1–2dB — not enough to explain an obvious offset.
30-second self-check. Measure with a tape from each speaker to the sweet spot; if they differ by more than 10cm, set the distance in the AV receiver first; then play the test tone and read each speaker to the same number with an SPL meter or a phone; finally play pink noise and find the point where the image comes back to center.
When after-sales service is required. Still more than 3dB off after distances and levels are aligned; one cabinet has breakup, noise or obvious distortion; the same cabinet is still quiet when moved — that is the driver or the crossover.
The cost: calibration needs an SPL meter or a phone, 20 minutes; an asymmetric room cannot be fixed, and once the levels are pulled even another seat goes off; forcing 3dB up eats power headroom, and loud passages distort first.
6. When to call someone in: installation, warranty, service requests, and the shutdown red lines
What installation and setup include. An on-site visit to measure ceiling height and the void above the ceiling, find the joists, fix the sofa's center axis, confirm the power locations; cut the openings, hang the cabinets, run the wiring; set the subwoofer position, crossover point, phase and each channel's SPL; and finally sign off against the acceptance sheet. The hole positions, depths, power and access panels that home theater design tends to miss are all on that sheet.
Warranty coverage. Per the warranty card: the unit, the drivers and the amplifier module are listed separately with their own terms; non-human damage is covered. Water ingress, drops, unauthorized disassembly, and drivers burned by overload are not. For in-ceiling cabinets, removal, reinstallation and restoring the ceiling are included if the card says so; if not, they are billed separately.
Where to file a service request. The official service hotline, the WeChat official account, and the store you bought from or an authorized dealer — any of the three can open a case; when you file it, give the model, the symptom, and the checks you have already done.
When you must shut down immediately. A burning smell, smoke, a continuous abnormal noise inside the unit (not something in the music — a ticking, humming or metallic sound from the cabinet or the amplifier), a case that is hot to the touch, an indicator light repeatedly reporting protection. There is only one action: pull the plug, do not just press standby on the remote; do not power up for a second try; photograph the scene, record a clip of the sound, then file the service request.
The cost: an on-site visit is not free — travel, scheduling and a second visit all count, and the further out the city the longer the wait. Half of these five matters are settings rather than quality, and checking them yourself saves money and the days spent waiting for the technician. But self-checks are no substitute for professional setup — subwoofer position, crossover, SPL: with ears and a phone you get to "audible", not to "right".
Who shouldn't buy it: anyone who wants to install it and never touch it again — the first week needs adjustment, and you will need to understand what happens when the router changes. A living room of only eight or nine square meters where the TV does most of the work: five in-ceiling speakers plus a sub gives limited return. Anyone with very sensitive neighbours downstairs who will not do vibration isolation: a floating floor will do more than new equipment. Anyone whose budget stops at ¥10,000: from ¥17,200 is the equipment price, excluding the ceiling and the setup.
SNAIL POWER was founded in Milan in 1995; its China entity is Shenzhen New Zeyu Audio Technology Co., Ltd., with its Asia-Pacific headquarters in Shenzhen. The 5.1 system comprises five CW90 speakers, one W10 subwoofer and one MS-1; once installed you cannot see that a cinema has gone in — which is the result an invisible cinema speaker system is after.
