A Superb Series Offering Dedicated Audio Engineering with Versatile Music Playback
Without a doubt, digital technology is making some noise in the audio industry. But rest assured that any noise—particularly signal noise—
is noticeably absent from the A-933 integrated amplifier and C-733 CD player thanks to Onkyo’s commitment to promoting the cleanest signals
through its proprietary technologies like VL Digital, VLSC (Vector Linear Shaping Technology) and Direct Digital Path. The A-933’s dual toroidal
power transformers and thick bus plate support a large, stable flow of current and also work to reduce impedance. The C-733 CD player’s
impressive engineering enables a super signal-to-noise ratio ensuring supreme playback quality. Capping off this series is the T-433 FM/AM RDS
tuner, which uses RDS and Accuclock to deliver radio frequencies that will surprise you with their precision and clarity. Use these components
as they best meet your needs.
Exclusive VL (Vector Linear) Digital Technology and 
PWM (Pulse Width Modulation)
Onkyo’s VL (Vector Linear) Digital technology is used to reduce digital pulse noise
when analog input signals are converted to digital signals. By converting data
between sampling points, and then joining the discrete sampling points in real
time, it is possible to produce a smooth output wave form—a virtually noise-
less signal. Pulse Width Modulation (PWM) is an efficient method of amplifying
audio signals. With high frequency signals, the pulse is longer, which creates
the risk of phase inaccuracies created by pulse noise in the original signal.
Onkyo combines VL Digital technology with PWM to significantly reduce these
inaccuracies and ensure the transmission of a noiseless signal.
