01 Safety
- Read this manual completely before installing or operating the SSOUNDS A14X.
- This equipment is intended for use by trained professionals. It is not a consumer product.
- Sustained high sound pressure levels cause permanent hearing damage. Protect yourself and the audience, and observe local noise-at-work limits.
- Disconnect mains power before making or breaking any connection, and before removing any panel.
- Do not defeat the protective earth. Ensure the supply is correctly rated and protected.
- Do not operate the unit if the enclosure, grille, connectors or rigging hardware are damaged. Withdraw it from service and have it inspected.
- Keep the unit dry unless it is rated otherwise. Do not restrict ventilation.
02 Unpacking and inspection
Inspect the shipping carton before opening. If there is visible damage, photograph it and notify the carrier and support@s-soundspro.com before proceeding. Retain the packaging: it is the only approved way to return the product under warranty.
- Check the enclosure, grille and finish for transit damage.
- Check every connector for bent or displaced contacts.
- Confirm the model and serial number against your delivery documentation.
03 Product overview
4-channel touring amplifier for line arrays, 4 × 2,000 W @ 4 Ω, analog input.
| Net weight | 6.5 kg / 14 lb |
|---|
04 Connections
Make all connections with the unit powered down. Confirm the mains supply matches the rating below before connecting it, and never defeat the protective earth.
| Inputs / outputs | 4 × XLR in · 4 × NL4 speakON out |
|---|---|
| Input sensitivity | 0 dBu / 6 dBu selectable |
| Nominal impedance | 2 Ω (all channels driven) |
| Mains supply | 100–240 V switch-mode with PFC |
05 Amplifier configuration
| Channels | 4 × Class-D |
|---|---|
| Power @ 8 Ω | 4 × 1,000 W |
| Power @ 4 Ω | 4 × 2,000 W |
| Minimum load impedance | 2 Ω (all channels driven) |
| Bridged @ 8 Ω | 2 × 4,000 W |
| Total output | 8,000 W |
- Load the SSOUNDS preset for the loudspeaker being driven before connecting it. Running a cabinet without its preset removes driver protection.
- Check the load per channel against the ratings above; do not take any channel below its rated minimum impedance.
- Set gain structure so the unit's limiters, not the console, define the system ceiling.
06 Rack installation and cooling
| Format | 19″ 1U rack |
|---|---|
| Weight | 6.5 kg / 14 lb |
| Cooling | Forced-air front-to-rear, variable-speed fans under continuous temperature monitoring |
| Protection | Over-current · thermal · DC · short-circuit |
- Support the unit on rack rails or a shelf. Front rack ears alone will not carry it in transit.
- Cooling is forced-air front-to-rear, variable-speed fans under continuous temperature monitoring. Keep the intake and exhaust clear and do not reverse the airflow path within the rack.
- Do not blank the airflow path between units, and do not rack against a sealed rear door without forced ventilation.
- Allow the unit to reach ambient temperature before powering up after cold transit; condensation inside mains electronics is a hazard.
- Confirm the supply matches 100–240 V switch-mode with PFC and that the circuit is rated for the full rack load before energising.
07 Operating limits
Published maxima are specified under the conditions stated on the data sheet and are not a continuous operating target. Sustained operation into limiting shortens driver life. If the system is limiting to reach the required level, the system is too small for the venue. Add elements rather than drive harder.
08 Care, maintenance and inspection
- Clean the enclosure with a dry or slightly damp cloth. Do not use solvents.
- Vacuum the grille from the outside; do not push debris through it.
- Keep connectors clean and dry; cap unused multipin connectors in transit.
- Store in transit protection, off the floor, in a dry space.
| Before every deployment | Visual check of enclosure, grille, connectors |
|---|---|
| Every 12 months | Detailed inspection by a competent person |
| After any impact or fall | Withdraw from service and inspect before reuse |
09 Troubleshooting
| No output from one section | Check amplifier channel, preset assignment and the multipin pin map; swap the loom to isolate. |
|---|---|
| Distortion at moderate level | Check for a driven-into-limit amplifier channel, a wrong preset, or a damaged driver. Stop and investigate. |
| Level lower than expected | Confirm the correct preset, check for a polarity error between cabinets, and verify the load per amplifier channel. |
| Intermittent output | Suspect the loom or connector before the cabinet. Re-terminate or replace and re-test. |
| Rattle or buzz | Check grille fixings, handles and hardware before assuming driver damage. |
If a fault persists, stop using the unit and contact support@s-soundspro.com with the model, serial number and a description of the fault.
Limited warranty: two (2) years
SSOUNDS products are warranted against defects in materials and workmanship for a period of two (2) years from the original date of purchase by the end user. Within that period SSOUNDS will, at its option, repair or replace the defective item with no charge for parts or labour. The item must be adequately packaged and dispatched, carriage pre-paid, to SSOUNDS or an SSOUNDS-authorised service centre, accompanied by proof of purchase and a returns reference issued in advance by SSOUNDS. Unauthorised repair, modification or removal of serial-number labelling voids this warranty.
This warranty does not cover
- Cosmetic wear, finish, grille cloth, paintwork and consumable parts.
- Damage caused by misuse, abuse, accident, neglect, or operation outside the published ratings on this sheet.
- Damage caused by transport or handling after delivery, or by inadequate packaging on return.
- Damage caused by mains or generator supply faults (over-voltage, under-voltage, phase imbalance, surge or incorrect earthing) or by lightning.
- Water, dust or corrosion ingress on products not carrying a published IP rating for the conditions of use.
- Damage resulting from amplification or processing outside the recommended configuration on this sheet, or from third-party presets.
- Products not purchased from SSOUNDS or an SSOUNDS-authorised distributor.
This warranty is in addition to, and does not affect, any statutory rights the purchaser may have under applicable consumer law. It is the sole warranty offered; no other warranty, express or implied, is given.
