About the Reference 9 V3
The Reference 9 V3 is a Class D monoblock power amplifier, sold as an individual amplifier rather than a stereo pair. Its V3 amplifier circuit revised the feedback path and operating bandwidth compared with the earlier V2 version. It provides RCA single-ended and balanced XLR inputs, with selectable input connection. Published specifications list 175 watts RMS into 8 ohms and 335 watts RMS into 4 ohms. This is the standard V3 model, not the separately designated Reference 9 V3 Special Edition.
