Entry-Level Onkyo Receiver Gets Power Boost and ProLogic IIx Processing

04/21/04 - Onkyo has upgraded its budget 6.1-channel TX-SR502 A/V receiver with a power increase to 75 Watts per channel, and improved surround processing, including Dolby ProLogic IIx and DTS-96/24. The model includes a suite of high-end features, including 6.1 channel processing for Dolby Digital EX and DTS-ES, and HDTV capable component video switching. This Onkyo TX-SR502 is currently available, in both black and silver finishes.

With the addition of Dolby Laboratory's new ProLogic IIx processing, the Onkyo TX-SR502 takes the guesswork out of surround processing by automatically deriving full 6.1-channel audio from absolutely any stereo or multichannel source. The receiver employs high quality linear PCM 96 kHz/24-bit D/A converters and a sophisticated 32-bit DSP processor for ideal reproduction of soundtracks and multichannel audio.

The TX-SR502 also boasts 50 MHz component video switching, allowing the receiver to switch high definition video signals without degrading video quality. There are two component video inputs and one output, four A/V composite inputs and two outputs with alternate S-Video connections, plus front panel A/V composite and S-video inputs for convenient connection of portable devices. The receiver has four assignable digital audio inputs with one coaxial and three optical connectors, RCA line-level connections for a CD player and audio recorder, and a subwoofer preamplifier output. There are dual banana-plug-compatible multi-way speaker binding posts for all main channels with color-coding for simplified wiring, and front channel "B" terminals for a second set of stereo speakers.

The Onkyo TX-SR502 includes six internal power amplifier channels with high-current, low-impedance discrete output devices, to deliver a continuous power output of 75 Watts per channel into 8-Ohm loads. Onkyo's WRAT (Wide Range Amplifier Technology) gives the power stage a linear frequency response from 10 Hz to 100 kHz to ensure it’s up to the challenge of the most demanding audio sources, such as SACD and DVD-Audio.

The dot-matrix fluorescent front panel display makes setup and operation of the receiver easy and fast, including variable speaker configuration and distance settings for simple optimization of any speaker arrangement. With the new adjustable crossover on the subwoofer pre-out channel, the LFE channel signal can be cutoff at 60, 80, 100, 120 or 150 Hz, for seamless integration of any satellite and subwoofer combination.

The receiver's high quality AM/FM tuner section has 30 random presets, and FM automatic scan tuning. The included preprogrammed remote control makes system integration and control simple and convenient.
