Additionally with the integrated switch mode power supply and high efficiency controlled output sections any measurements used for testing must be referenced to the appropriate ground or alternative reference point. The Crown Xti amplifiers are universally built upon a design integrated into one uniform circuit board assembly which necessitates different troubleshooting methods to isolate problems. We are equipped and experienced in dealing with these technologies including the rework of surface mount components and the proper repair procedures, calibrations and performance verifications to be made on these newer technologies.Ī look at the extensive SMT technology on XTi circuit boards Because of the complexity many times it can be complicated or intimidating for many technicians to tackle these amplifiers.

We have extensive experience in troubleshooting and repairing all types of amplifiers including the high efficiency and lightweight designs using switch mode power supplies and extensive control circuits to monitor amplifier operation. Many of these problems can be avoided with proper operation and maintenance but there may also be times that a failure means a repair is needed, While their reliability is certainly good, as with all things electronic there will be some failures ranging from simple connection issues to output section or power supply failures that are more complicated to troubleshoot and fix. The same technology is used in the CDi and DSi series of install specific power amplifiers. These are exceptionally good amplifiers in the lightweight and efficient category of power amplifiers while also being affordable and reliable. Crown XTi and XTi2 series amplifiers have been some of the most prolific and widely used power amplifiers in the sound equipment market for many years.
