Dynamic Audio Amplification: Rated at 100 watts (8 Ohms, 20
Hz-20 kHz, 0.08% THD, 2 Channels Driven, FTC), the TX-8270 is Onkyo's best
stereo receiver for driving speakers. This amp system generates high current
with a massive transformer and audio-grade capacitors. Circuitry features
discrete output transistors for low distortion and effortless driving power.
High current assures accurate control, restoring energy and vitality to your
music. Non-phase-shift circuitry, meanwhile, focuses the audio image and
reproduces a wide frequency bandwidth to maximize Hi-Res Audio and vinyl
- Massive Hi-Current EI Transformer: The Massive Hi-Current EI
Transformer delivers large amounts of power necessary for reproducing the
wide dynamics of movie soundtracks and the detail and clarity of your music.
- Non-Phase-Shift Amp Design: The receiver employs a
Non-Phase-Shift amp design which prevents phase shift by pushing the
roll-off point higher than the listening-level frequency. This creates a
well-focuses and realistic audio image.
- Optimum Gain Volume Circuitry: Optimum Gain Volume
Circuitry adjusts the gain so that less than half the amount of attenuation
is needed, ensuring the signal never comes close to the noise floor. This
protects the signal against noise, resulting in a dramatically clearer
384kHz/32-Bit Hi-Grade DAC: The Onkyo TX-8270 utilizes one
premium-quality AK4438 digital-to-analog converter from AKM ideally suited to
DSD 5.6 MHz and PCM signals up to 192 kHz/24-bit.
Vector Linear Shaping Circuitry (VLSC): Onkyo developed
Vector Linear Shaping Circuitry (VLSC) to reassemble the signal in its original
form following processing. Unlike conventional filters, VLSC removes pulse noise
generated in D/A conversion, allowing the sound wave to be reproduced with
extremely high fidelity for a smooth analog signal. The signal's data is
converted between sampling points and joined with analog vectors in real time to
produce a smooth output wave form. The result is a virtually noiseless, smooth,
analog signal that brings out even the most subtle of nuances in music sources.
