About the Onkyo TX-8255
The Onkyo TX-8255 was made for audio enthusiasts who want great stereo sound but don't need all the bells and whistles of a home theater model. It's perfect for that cozy den or bedroom where you can relax and just listen to music. And Onkyo's rock-solid construction and careful attention to detail ensure that your sound stays pure, powerful, and dynamic at all times.
Exceptional build quality
At the heart of the '8255's impressive performance is Onkyo's renowned low-impedance amplifier design. Its oversized, shielded transformer provides maximum power capacity and stability while minimizing hum. An efficient heavy-duty extruded aluminum heat sink ensures cooler operation and longer life from your receiver. Plus the rigid, reinforced chassis and aluminum front panel fight performance-robbing vibration. These thoughtful design touches enable the receiver to drive your speakers with ease, for stellar sound you'll enjoy for years to come.
Versatile, convenient, and iPod® compatible
The '8255 provides plenty of inputs for all of your audio gear. You can connect up to six components, including a turntable. The built-in AM/FM tuner features 40 presets for all your favorite radio stations, plus direct access tuning to quickly jump to a specific frequency. Two sets of main speaker outputs let you connect an additional pair of speakers. Plus, you can add Onkyo's optional control dock to enjoy listening to tunes on your iPod® through your stereo system. You can even use the receiver's handy remote to control your iPod while it's docked.

Features
WRAT (Wide Range Amplifier Technology): This technology uses low-negative-feedback circuit topology for accurate signal reproduction, improved dynamic signal-to-noise ratio, and better delivery of power peaks.
Speaker Outputs: There are binding post connectors for the A and B speaker outputs. The binding posts are not 5-way because a plastic collar prevents their use with spade lugs.
Headphone Output: This receiver has a standard 1/4" headphone output on the front panel. The A and B speaker outputs are not automatically muted when you plug in headphones; they must be turned off using the buttons above the headphone jack.
Tuner Presets: Up to 40 AM or FM radio presets can be programmed; each can be assigned a customized name, up to 8 alphanumeric characters.
Tape 2 Monitor Loop: The stereo receiver's Tape 2 input is equipped with a monitor loop for connecting an external EQ.
Sleep Function: From the remote, you can set the unit to automatically turn off after as much as 90 minutes or as little as 10 minutes; choices are presented in 10-minute increments.
Display Dimmer: The display can be adjusted to one of three brightness levels.
Remote Control
Remote Control: The remote controls this unit and compatible Onkyo cassette players and CD players.
IR Input/Output: A commercially available IR receiver can be connected to the IR In jack, allowing you to control the receiver while you're in another room, or when the receiver is out of sight. An optional IR emitter can be connected to the IR Out jack to pass IR commands to other components.
RI Remote Control Jack: The 1/8" RI remote control jack allows you to connect this receiver to compatible Onkyo components.

Just What I wanted. Pulls in FM stations well. Has plenty of "old fashioned" inputs for what I use. It is hard to find something that isn't meant for home theater these days with the extra cost and complexity. It was refreshing to find "Just the basics; well done". Straight forward controls too.
