Warranty and Warranty for Repair Service

All microphones provided by GRAS are constructed with a stainless steel protection grid and housing as well as a special stainless alloy diaphragm for unmatched durability and longevity.

All our high-precision (class 1) measurement microphones are delivered with a 5-year warranty against defective materials and workmanship. This also applies to the diaphragm. When you purchase a GRAS microphone you, therefore, not only purchase the market’s most durable measurement microphone, you also make an investment for the future.

Warranty

As a general rule, however, we only provide warranty against defective materials and workmanship caused in connection with manufacturing the product. Therefore, products not covered by the warranty are products for which the damage is the result of negligent use, incorrect power supply or incorrect connection to the equipment.

The 5-year warranty applies to special microphones and microphone sets like flush-mount microphone sets, probe microphones and sound intensity probes.  

Likewise, outdoor and environmental microphones, ground array kits and hemisphere kits as well as preamplifiers are covered by a 5-year warranty. For the outdoor microphones 41AM and 41CN, the 5-year warranty is, however, conditioned upon one yearly service. Otherwise, the warranty is 2 years. The 5-year warranty also applies to couplers, ear simulators as well as accessories.

All low-noise microphones are delivered with a 3-year warranty.

Array and QC microphones are covered by a 2-year warranty. This is also valid for KEMAR, acoustic test fixtures, calibration equipment as well as power modules. 

Cables and windscreens are covered by a 6-month warranty. For cables integrated in products such as preamplifiers, microphone sets, intensity probes and ear simulators, the 6-month warranty is also valid.
