YSS952 comes at an affordable price, yet integrates a high-performance programmable 32-bit floating point DSP.
A powered-up AudioEngineTM HD applies acoustics fine-tuning to the response of a specific chassis (Acoustic total-linear EQ). Natural sound which no peers ever achieve can be produced by applying various acoustic effects to this ideal response.

This places movie dialogs in the center while positioning the sound effects not merely to left and right but also in front and behind, enveloping the listener.
Harmonics enhancer ExtendedBoosting the sub-harmonic of bass components and reconstructing mid and treble components lost in audio compressions adds percep-tual depth.
SupportOffers of a sound-parameters creation tool etc. and consulting service by Yamaha acoustic technicians are provided.
Signal Processing FirmwareNumerous varieties are provided, such as those suitable for flat-screen televisions or karaoke applications.
KaraokeThe built-in voice cancellation effect allows casual karaoke enjoyment. Mic echo, reverb, and key control are possible.
Acoustic total-linear EQ is “total linear phase acoustics tuning technology” that compensates for the acoustic response of a specific chassis, not just in the frequency domain but also in the time domain.
