5.1ch AV Receiver: The Onkyo TX-SR313 features a 5-channel
amplifier rated at 65 watts (into 8-ohms, at 20Hz-20kHz, with 0.7% THD, driving 2
channels) and a mono subwoofer preamp output.
WRAT (Wide Range Amplifier Technology): WRAT is based around
a low negative-feedback circuit topology that works to reduce signal noise and
distortion across the frequency range. A "closed ground-loop circuit" design is
employed, in which each circuit has a separate link to the power supply. This
helps to cancel individual circuit noise and keep the ground potential free of
distortion. High Instantaneous Current Capability (HICC) enables WRAT amplifiers
to immediately cancel the speakers' reflex energy and instantaneously send out
the next signal. The same high current better manages speaker impedance
fluctuations, which can negatively affect performance.
H.C.P.S. (High Current Power Supply): Under the
anti-resonant cover of any Onkyo receiver, you'll instantly notice the High
Current Power Supply (H.C.P.S.) transformer. With its huge, isolated power
supply design and high-capacity filter capacitors, it delivers the large amounts
of power necessary for reproducing the wide dynamics of movie soundtracks and
the detail and clarity of your music.
Optimum Gain Volume Circuitry: Optimum Gain Volume Control 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 sound
Burr-Brown DACs (Digital-to-Analog Converters): This receiver is
equipped with 192kHz/24-bit Burr-Brown DACs to decode and playback
high-resolution recordings with less jitter and clearer sound.
32-Bit Processing DSP: The Onkyo TX-SR313 is equipped with a powerful
and highly accurate 32-bit processing DSP (Digital Signal Processor) for better
surround sound reproduction.
Listening Modes: This receiver incorporates a wide variety of listening modes to bring you
maximum enjoyment from your audio and video software. You can assign a default
listening mode to each input source so that listening mode will be selected
automatically when you select the corresponding input source. The following
audio formats are supported by the receiver's Listening Mode - Mono, Stereo,
5.1-channel, and 7.1-channel.
| Stereo ||Sound
is output by the front left and right speakers and subwoofer. |
| Mono ||Use
this mode when watching an old movie with a mono soundtrack. |
| Direct Modes |
| Direct || In this mode, audio from the input source is output
without surround-sound processing. This mode delivers pure sound
with minimum sound quality adjustment and filtration. |
| Dolby Pro Logic |
| Dolby Pro Logic II ||Dolby
Pro Logic II transforms high-quality stereo sound into 5.1-channel
surround sound. Thanks to its full-range performance, you will hear
all the detail and subtleties of a compelling five-channel Dolby
surround sound mix from a stereo signal. You can select between PLII
Movie, Music, and Game modes. |
| Dolby Digital |
| Dolby Digital ||Dolby
Digital has been selected as the default format for DVD video,
standard 2 channel audio playback and HDTV Digital broadcasting.
Dolby Digital features two independent surround channels giving same
full range as the three front channels. Plus it adds a Low Frequency
Effect channel LFE. Dolby Digital accomplishes this by using a
technique called compression. |
| Dolby Digital Plus || Dolby Digital Plus is based on core Dolby Digital
technologies. Dolby Digital Plus is an advanced
surround sound audio codec
designed specifically for evolving media. Dolby Digital Plus brings
cinematic sound to Blu-ray,
broadcast, online, game, and mobile phone entertainment (up to
| Dolby Digital TrueHD ||Dolby
TrueHD produces audio that is identical to and every bit as
spectacular as the master recording. It lets you experience the full
potential of Blu-ray Disc (up to 7.1ch), and is even ready for
future HD delivery formats. |
| DTS |
| DTS ||DTS
(Digital Theater Systems) uses the same concept as Dolby Digital,
but implements a lower compression rate. This leads to more dynamic
range, improved channel separation, and more subtle nuances. |
| DTS-HD || High Resolution Audio || DTS-HD Audio delivers sound quality that matches the
clear and vivid images of high-definition video. Blu-ray and HD-DVD
discs deliver five times the video resolution of standard DVD and
produce images with stunning realism. But that's only half of the
story. You need incredible sound to complete the high definition
experience and DTS-HD Audio provides the highest quality
multi-channel (7.1ch) sound possible. Movies come alive with sound
as lifelike as the picture, and music becomes as real as a live
| Master Audio |
| DTS 96/24 || DTS 96/24
offers a higher quality level of multi-channel audio (up to 5.1
channels) for standard DVDs. The "96" refers to a 96kHz sampling
rate (compared to the typical 48kHz sampling rate.) The "24" refers
to 24-bit depth, compared to 16-bit depth used for CD sound, which
means there is more audio information present. |
| DTS Express ||DTS
uses a system called DTS Express to deliver Secondary or Sub Audio
to your player. The DTS Express audio is mixed with the Primary
Audio, giving you an intensely great interactive surround
| DTS Neo: 6 ||DTS
Neo:6 takes 2-channel (stereo) audio and completely transforms it
into up to six full-bandwidth matrix channels of surround sound.
Your home theater system will produce six and five separate
channels, respectively, to match your speaker layout. DTS Neo:6 can
also generate a center surround channel from 5.1 material. |
| Onkyo Original DSP Modes |
| Orchestra ||For classical or operatic music.
| Unplugged ||For acoustic instruments, vocals,
and jazz. |
| Studio-Mix ||Suitable for rock or pop. |
| TV Logic ||Adds realistic acoustics to TV
| Game ||The receiver offers four different
Gaming modes - RPG, Action, Rock, and Sports. |
| All Channel Stereo ||Stereo sound from all speakers.
Ideal for background music. |
| Full Mono ||All speakers output the same sound
in mono. |
| Theater Dimensional ||Theater-Dimensional circuitry takes
the complexity out of conventional surround-sound setups and lets
you experience the excitement of surround sound from as few as two
ordinary speakers. Theater-Dimensional's unique multi-speaker modes
let you place up to five speakers conveniently by the TV, for the
most realistic virtual-surround sound possible. |
| Other Listening Modes |
| DSD || Audio signals are stored as single-bit values at a
high-frequency sampling rate of 2.8224 MHz, while noise shaping and
oversampling are used to reduce distortion - providing a better
audio quality with a dynamic range of up to 128 db. |
| Multichannel ||This
mode is used with PCM multichannel sources. |
Note: Dolby Digital
and DTS listening modes can only be selected if your audio source is
connected to the AV receiver via a digital audio connection (HDMI,
optical or coaxial). Even though the AV receiver will decode 7.1channel
surround sound (via HDMI), it will only output 5.1ch surround, because it lacks
Surround Back channel speaker outputs.
Dolby Pro Logic II Music Settings: While listening in the
Dolby Pro Logic II Music format, there are three further enhancements you can
- Panorama: Broadens the front
stereo image to the surround speakers to provide a
wraparound effect, especially effective when there
is limited output from the surround channels, panorama
can be turned on/off in the menu.
- Dimension: Allows you to move
the sound field forward or backward.
- Center Width: Allows you to
adjust the width of the center channel.
Center Image: In the Neo:6 Music mode, the Center Image
feature adjusts the output of the left and right channels relative to the center
channel, allowing you to make the center channel more or less dominant as needed.
This improves the image of the center channel, especially when the listener is
off-center. Adjustment varies from 5 (nothing subtracted from the L/R channels)
to 0 (L/R channel output is cut in half).
Listening Angle: While listening in the Theater Dimensional mode you
can adjust the listening angle to either Wide (if listening angle is 40-degrees)
or Narrow (if listening angle is 20-degrees).
Speaker Setup: The Onkyo AV receiver allows you to manually setup your
system's speaker configuration.
- Speaker Size: You can set Large or
Small for your front speakers; Large, Small or None for
your surround and center speakers; and Yes or No for subwoofer.
- Speaker Distance: The front speaker distance can be set from 1
to 30' in 1' increments. The center and subwoofer
settings can be up to 5' more or 5' less than the
distance you set for the front speakers (30' max). The
settings for the surround left and right speakers are each
individually adjustable, and they may be adjusted up to 5'
more or 15' less than the distance you set for the
front speakers (30' max).
- Adjustable Crossover: This receiver has a built-in high-pass
crossover for any of the speakers set to Small. This setting is available when
the subwoofer is set to Yes. The frequencies that you can choose from are 40, 50,
60, 80, 100, 120, 150, and 200 Hz. Frequencies lower than the set crossover point
are output by the subwoofer.
- Speaker Levels: You can manually
adjust the level of individual speakers between -12dB
and +12dB; -15dB to +12dB for the subwoofer.
Bass & Treble: You can independently adjust the Bass (50Hz)
and Treble (20kHz) of the TX-SR313 from -10 to +10 dB.
Double Bass: This setting boosts the bass output by feeding
bass sound from the front left, right, and center channels to the subwoofer.
CinemaFilter: Using the CinemaFilter you soften overly bright movie
soundtracks. Movie soundtracks are typically mixed for a large theater (relative to your
home theater) with lots of soft seats and thick curtains on the walls. Home theater
settings often lack these high frequency absorbing wall treatments, making the soundtrack
sound too bright. CinemaFilter accounts for this and for many movies sounds more natural
Music Optimizer: The Music Optimizer function enhances the sound
quality of compressed music files. The Music Optimizer function only works with PCM
digital audio input signals with a sampling rate below 48kHz and analog input signals.
Late Night Feature: The Late Night feature limits the dynamic
range of Dolby Digital recordings. Limiting the dynamic range makes it easier to
find a volume that ensures the quiet sounds are not too quiet and the loud sounds
are not too loud for night time listening. This allows you to comfortably listen
to without the need to constantly adjust the volume to keep from waking family/neighbors.
The choices are: Off, Low, and High.
Note: This feature only works
with Dolby Digital Encoded software and the depth
of the feature will vary based on the individual
ARC (Audio Return Channel): This feature allows audio to be
sent from your compatible high-definition TV to your receiver through the same HDMI cable
already being used to send audio and video to your television. This eliminates the
need for extra cables connected to your television.
Assignable Digital Inputs: The Onkyo receiver is equipped with
two optical digital inputs and one coaxial digital input. All three digital inputs
are assignable. You can choose auto decoding , PCM, or DTS for the digital audio
inputs. Auto will decode the signal in its original form (Dolby Digital, DTS,
PCM, etc), PCM decodes the signal to 2-channel, while DTS decodes only DTS
Spring-Clip Speaker Terminals: There are color-coded
spring-clip terminals for all speaker connections - Front A, Front B, Center,
Note: Speaker B can be used to listen to 2-channel stereo playback
in other room. When Speaker B is on, your main speakers are limited to
Headphones: When headphones are plugged into the full-size
1/4" jack on the front panel, all the speakers are automatically muted.
AM/FM Tuner: With the built-in tuner you can enjoy AM and FM radio
station. You can store your favorite stations as presets for quick selection.
You can store a combination of up to 40 of your favorite FM/AM radio stations as
HDMI (v1.4): The TX-SR313 has four assignable HDMI v1.4
inputs and one HDMI v1.4 output for connecting Blu-ray/DVD players,
Game Consoles, and other video components to your TV. The receiver's HDMI
circuitry allows the receiver to output an HDMI audio signal from its speaker
outputs, headphone out, and HDMI out so you don't have to run and additional
analog or digital cable. The HDMI inputs can accept and switch 480i, 480p, 720p, 1080i, and 1080p video signals to
a high-definition TV. The HDMI inputs will support uncompressed standard or
high definition digital video along with the following audio signals; 2-channel
linear PCM, Multichannel linear PCM (up to 7.1ch), and Bitstream (Dolby
Digital/DTS, etc). Each HDMI input is
3D-Compatible: The TX-SR313's HDMI v.1.4 connections will accept 3D
video from your 3D-ready Blu-ray player and output the video signal in 3D to
your 3D-ready HDTV.
x.v.Color: The AV receiver supports x.v.Color, offering a
wider color range than the current broadcast standard. For the x.v.Color feature
to be useful, the entire video production chain must be compatible
Deep Color: The Onkyo receiver also supports Deep Color
which allows the color depth of video signals passing through HDMI to be raised.
The number of colors that could be expressed by 1 pixel was 24 bits (16,777,216
colors) with a standard HDMI jack. However, the number of colors which can be
expressed by 1 pixel is 36 bits with a Deep Color enabled HDMI jack. Since the
gradation of the depth of a color can be expressed more finely with more bits,
continuous color changes can be more smoothly expressed. For the Deep Color
feature to be useful, the entire video production chain must be compatible
Note: x.v.Color and Deep Color technology are supported
only when source product, HDMI cable, media and HDTV all support those
HDMI Through: When enabling the HDMI Through function,
regardless of whether the AV receiver is "on" or in "standby" both audio and
video streams from an HDMI input will be output to your television, via the
receiver HDMI monitor output. You can select between 3 HDMI Through functions
- Auto: Detects the signal and automatically selects the
- Source: Selects the input source (BD/DVD, VCR/DVR, CBL/SAT,
Game, PC, Aux, TV/CD) for which the HDMI Through function in enabled.
- Last: The HDMI Through function is activated on the
input source selected at the time of setting the AV receiver to the
Auto Lip Sync: The Lip Sync function can automatically
synchronize HDMI audio and video that has gotten out of sync due to the
complex digital video processing being performed by your HDMI-compatible TV.
With HDMI Lip Sync, the audio delay required to synchronize the audio and
video is calculated and applied automatically by the AV receiver.
A/V Sync Control: Occasionally, you may need to manually
adjust the audio/video signals that are not
properly synchronized manually. Typically when using a progressive scanning DVD player. You
can correct this by delaying the audio; options are 0 (no delay) to 400 milliseconds,
in 20 millisecond steps.
Component Video: There are 2 component video inputs and 1 component video output. The
component video inputs and outputs have a bandwidth of 5Hz to 100MHz.
Front-Panel AV Input: The Onkyo TX-SR313 is equipped with a
front-panel audio/video input which consists of a composite video terminal and
stereo audio RCA jacks.
