Inputs and Outputs Notes
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.
Digital-to-Analog Converters: To decode and playback high-resolution
recordings, this receiver is equipped with 96kHz/24-bit DACs on all channels.
New Surround Modes: The Onkyo
TX-SR502 features Dolby Pro Logic IIx, a new surround mode from Dolby Laboratories,
plus two combined modes using existing Dolby and Digital Theater
Systems (DTS) surround modes:

mode can create 6.1-channel surround from two-channel material (except 96kHz
PCM). Dolby Pro Logic IIx has 3 modes: Movie, Music
and Game (for 2-channel sources only). The DPL IIx Music mode can create 6.1-channel surround from
5.1-channel audio material.
- DTS+Neo:6: This mode uses
the Neo:6 decoder to create 6.1-channel surround from DTS 5.1-channel
material. It can be used with CDs, DVDs, and LDs that bear the DTS or DTS
- DTS+Dolby EX: This
mode uses the Dolby EX decoder to create 6.1-channel surround from DTS
5.1-channel material. It can also be used with CDs, DVDs, and LDs that bear
the DTS or DTS 96/24 logo.

Basic Modes: This receiver has
two basic listening modes, Direct and Stereo, for use with 2-channel sources.
The Direct mode uses minimal signal processing to give you the purest sound
possible. The Stereo mode is processed as a stereo signal and output to the
front left and right speakers and the subwoofer.
This receiver has a built-in crossover for the speaker system. This setting is
available when you tell the receiver that there is a subwoofer being used, or
when you set your front speakers to "Small". Depending upon the size
of the drivers in the front speakers, you
can choose from the following cutoff frequencies: 60, 80, 100, 120 and 150Hz.
This function boosts the bass by feeding bass sounds from the front left and
right channels to the subwoofer. This works well with mono and 2-channel
sources, including 96kHz PCM.
Late Night (Dolby
Digital only): You can reduce the dynamic range of Dolby Digital
material so you can still hear quiet parts even when listening at low volume
levels. Loud passages, such as explosions, are subdued, so as not to disturb
This function can soften the harshness or brightness sometimes experienced
with movie soundtracks, which are typically mixed for reproduction in a
Sleep Function: From the
remote, you can set the unit to automatically turn off after a selected amount
of time. You can choose from between 10 and 90 minutes in 10-minute increments.
Display Dimmer: The
display illumination can be set to dim, dimmer, or normal brightness.
Multibrand Remote (RC-567M): The supplied wireless remote is an illuminated multibrand
remote. The remote is pre-programmed to operate Onkyo CD player or recorder, DVD, MD, and cassette
players connected via RI control cables. In addition, the remote is pre-programmed to operate other popular
brands of equipment, including DVD players, satellite receivers, cable boxes,
VCRs, and televisions.
and Outputs Notes
Assignable Digital Inputs: The
TX-SR502 features 3 optical (Toslink) and 1 coaxial digital inputs. There are no
digital outputs. Each input can be assigned to any input source except Phono and
Headphone Output: This receiver
has a standard 1/4" headphone output on the front panel.
Speaker Outputs: There are
color-coded binding post connectors for the left front A (white), right front A
(red), left front B (white), right front B (red), center (green), left surround
right surround (gray), and surround back (brown). The binding posts are not 5-way because a plastic collar prevents
their use with spade lugs. A sheet of color-coded speaker wire labels is
RI Remote Control Jack:
The 1/8" RI remote control jack allows you to connect this receiver to
compatible Onkyo components.
Input: The receiver is equipped with a 5.1 multi-channel input for
compatibility with 5.1-channel decoders. The input consists of left
front, right front, center, left surround, right surround, and subwoofer RCA inputs.
Component Video Switching: In
addition to composite and S-Video switching, this unit can switch between two
component video sources. There are 2 component video inputs and 1 component
video output; each input and output has jacks labeled "Y", "Pb"
and "Pr". This feature allows you to connect, and switch between, high
resolution video sources equipped with component video outputs. The component
video bandwidth is 50 MHz. Note: This receiver does not upconvert between
formats; video signals will be output in the same format as it was input.
