Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The Onkyo TX-RZ50 is rated at 120 watts RMS into 8-ohms (2 channels driven).
Here are the main highlights of its performance specs:
- 120 watts into 8-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)

Need more power?
Onkyo TX-RZ50 is rated at 120 watts into 8 ohms, which puts it in our 91 to 120 watts band. The next band up is 121 to 180 watts, which is worth about 1.5dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room. Plenty of systems are better served by the 61 to 90 watts band and better speakers.
When pairing the Onkyo TX-RZ50 with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
