Safety, Warranty & Service

Safety and Compliance

Before connecting headphones or powered speakers, reduce the listening level and raise it gradually once everything is connected. High sound levels can cause permanent hearing damage.

Warning: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. There are no user-serviceable parts inside. Refer servicing to qualified service personnel.

iD4+ is normally bus powered through the USB-C COMPUTER connection. The USB-C ALT POWER port is power-only and can be used when the host computer cannot provide sufficient power on its own. The interface does not contain a user-accessible high-voltage mains supply.

Important safety instructions

1. Power iD4+ from a USB-C computer port capable of supplying 5 V / 3 A (15 W), or connect an external 5 V / 3 A USB-C power supply to ALT POWER using a USB-C to USB-C cable. ALT POWER supplies power only, not audio or control data.
2. Switch off connected powered speakers before connecting or disconnecting iD4+, changing audio connections or removing its power. Switch speakers on only after the interface has initialised.
3. Before connecting or disconnecting a microphone, turn off +48 V phantom power for that input and reduce the monitoring level. Enable +48 V only for microphones or other equipment designed to receive it.
4. Keep iD4+, its cables and any power adaptor away from rain, moisture and splashing water. Do not place drinks or other liquid-filled containers on or near the interface.
5. Place the interface on a stable, dry surface away from heaters, direct sunlight and other sources of excessive heat. Allow space around the unit to prevent heat build-up.
6. Route USB, audio and power cables so they cannot be tripped over, crushed or pulled. Do not use cables, plugs or power adaptors that are damaged or frayed.
7. Before cleaning, disconnect the COMPUTER and ALT POWER connections, if used. Wipe the enclosure with a soft, dry cloth. Do not spray cleaners, solvents or liquids onto the unit.
8. During thunderstorms or extended periods without use, disconnect both COMPUTER and ALT POWER if connected. Disconnecting only one connection may leave the interface powered.
9. Do not open the enclosure or attempt repairs or modifications. If the interface has been dropped, damaged, exposed to liquid or is operating abnormally, disconnect power and contact Audient Support or qualified service personnel.

The warranty covers manufacturing defects during the warranty period. It does not cover faults or damage caused by improper use, normal wear and tear, use with an unapproved device, removal of or tampering with the serial-number label, or unauthorised electronic, digital, software or mechanical modification.

The warranty is additional to your statutory rights in the country of purchase. For the complete and current terms, see audient.com/warranty.

If a fault is confirmed, provide proof of purchase when requested and follow the return instructions from the original dealer or the distributor responsible for the country of purchase.

Warranty service is provided on a return-to-base basis. The product is normally returned carriage paid to the original dealer. If the product was purchased outside your normal country of residence, it may need to be returned to the original point of purchase at your cost. Shipping for the repaired return is covered by the local dealer, distributor or service agent.

Out-of-warranty service
