Experience 4K hi-def imagery

All THX Certified amplifiers are capable of playing at THX Reference Level volume when used with THX Certified loudspeakers. THX Reference Level is the exact sound level at which audio content is recorded in the post-production studio (85 dB plus 20 dB of dynamic headroom = 105 dB SPL). Listening at THX Reference Level ensures content is being reproduced at the same volume and nuances originally heard in the studio by the content creators.
