MCACC® Auto Room Tuning

Create the optimum acoustic environment with Pioneer’s MCACC (Multi-Channel Acoustic Calibration System), developed with the expertise of professional recording studios. With the custom microphone, the system automatically compensates for differences in speaker size, level and distance, and equalizes response. As an innovative solution for the phase lag between the subwoofer and the main channel speakers caused by the network filter, Phase Control compensates the delayed bass to improve sound synchronization.

Intuitive Control with New Pioneer Remote App (iOS/Android)*

Enjoy smooth control using your beloved device. With the free Pioneer Remote app, you can use your iPad/iPhone/iPod touch or Android smartphone for operating the AV receiver, or play back tunes stored on your device. You can also select internet radio stations, and play songs from your media server.

Item Condition

Item Condition

Pioneer Factory Refurbished

Buying a Pioneer Factory Refurbished product is a great way to get "as-new" products at a considerable savings. Every product has been thoroughly tested, repaired (if necessary), cleaned and otherwise renewed to original condition. Next it’s repackaged with accessories included. When you consider that a factory-renewed Pioneer product undergoes such close scrutiny for defects and workmanship, you might actually be buying something that is in many ways better than new. And for your piece of mind and protection, your purchase is covered by a full 1 year parts and labor warranty valid at any authorized Pioner repair center (you can look-up locations online here or call 844-679-5350)

Pioneer, like all electronics manufactures, receives products returned for various reasons. In 2011 consumers returned 17 billion dollars in electronics globally, of which less than 5% were found to be defective! Once a product has been opened it must be resold as refurbished and can’t be resold as new again. The history and reason why a product was returned is not provided to us, thus we can’t provide any additional details regarding its past. All products are processed by Pioneer certified technicians, where they are fully tested, repaired (only if necessary), and retested again to ensure the highest quality control. Each unit must pass a complete battery of test before it can be titled a "Pioneer Factory Refurbished" product.

Minor signs of wear (light surface scuffs or minor scratches) may be present. We DO NOT sell products that are cosmetically damaged (cracked displays, broken knobs, heavy scratches, or physically abused). Unfortunately, we can’t provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.
