Speaker System Features
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: The HT-R540 receiver is equipped with
192kHz/24-bit DACs for all channels to decode and play high-resolution recordings.
XM Satellite Ready: You can listen to XM
Satellite Radio by connecting an optional XM antenna designed for XM ready home
receivers. A 50' extension cable is available (item # 220CNPEX50) if the
antenna's cable is not long enough. XM Satellite Radio offers over 150
commercial-free channels of music, news, sports, comedy, talk, and entertainment
to choose from--all in digital quality. During XM playback, you can display the
channel number and name, category, artist name, and song title on the front
panel. Note: A subscription is required in order to receive XM Satellite
iPod Compatible: The DS-A1 or DS-A2 Remote
Interactive Dock for iPod (item #'s 580DSA1 and 580DSA2) provide an interface
between an iPod digital media player and Onkyo receiver. Once the iPod is docked
you can control basic functions such as volume control, play, stop, and skip via
the Onkyo system's RI-compatible wireless remote control. The dock also charges
the battery in the iPod, and allows you to view digital photos and video on an
Onkyo home theater system.
This receiver has a built-in crossover for the subwoofer output. This setting is
also used when you set your other speakers to Small. The frequencies that you can choose
from are 40, 50, 60, 80, 100, 120, 150, and 200 Hz.
Double Bass: With the double
bass feature you can boost the bass output by feeding the low frequency signals
from the left and right channels (when front speakers set to large) to both the
front speakers and to the subwoofer.
Assignable Digital Inputs: The
HT-R540 has 4 assignable digital inputs (3 optical, 1 coaxial) allowing you to
tell the unit which input source is connected to which digital input jack.
Although this unit features built-in Dolby Digital, Dolby Pro Logic IIx, and DTS
processing, it also has a 7.1 multi-channel analog input for use with external
multi-channel decoders (DVD-Audio, SACD, etc).
B Speaker Outputs: The B speaker outputs
can be used to power speakers in a different room, creating a second zone. When
the B speakers are turned on, the amplifier for the surround back speakers is
used to power them, so the connected surround back speakers are disabled and the
main room becomes a 5.1 channel system. The B speakers can only play sources
connected using analog cables.
Speaker Levels: Along with
adjustments for the front, center, surround and surround back speaker levels,
the B channel (2nd front) outputs can be adjusted from -12dB to +12dB relative
to the A channels. This essentially gives you independent volume control for the
A and B speaker outputs.
Listening Modes: This
receiver incorporates a wide variety of listening modes to bring you maximum
enjoyment from your audio and video software. The listening modes include:
- Surround Modes:
- Dolby Digital
- Dolby Digital EX
- Dolby Pro Logic IIx (Movie,
Music, and Game)
- Dolby Pro Logic II (Movie,
Music, and Game)
- Dolby Digital + Pro Logic IIx (Movie and
- Dolby Digital + Neo:6
- DTS-ES (Discrete and Matrix)
- DTS 96/24
- DTS Neo:6 (Cinema and Music)
- DTS + Dolby EX
- DTS + Pro Logic IIx (Movie and
- DTS + Neo:6
- Neural Surround
- DSP Modes:
- Mono Movie
- TV Logic
- All Channel Stereo
- Full Mono
Direct Mode: This mode delivers
pure sound with minimal sound quality adjustment and filtration. The sound
recorded for the right and left front channels is output to the right and left
front speakers and subwoofer only, not to the center or surround speakers.
Circuitry: This circuitry provides a subtle
high-frequency roll off for proper playback of soundtracks in the home. It provides the means to easily remove excess treble response from
soundtracks that were originally equalized to sound best in a large theater.
This function works with all the Dolby Digital and DTS modes, plus the Dolby Pro
Logic II and IIx movie modes.
Late Night: The Late
Night feature limits the dynamic range of Dolby Digital recordings making 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. The settings are:
Off, Low, and High.
Note: This feature only
works with Dolby Digital Encoded software and the amount of effect
will vary based on the individual soundtrack.
OptiResponse Equalizer: When
using the HT-R540 with the speakers included in the HTP-430 Home Theater Speaker
Package, by turning on the OptiResponse equalizer, you can enjoy a powerful
sound with movies or music.
Dolby Pro Logic II & IIx Music Modes: While
listening in the Dolby Pro Logic II or IIx Music format, there are three further
enhancements you can enjoy (available with 2 channel sources only):
- 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
- 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 DTS 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).
Neural Surround: Neural Surround has been
adopted by XM Satellite Radio for digital radio broadcasts of XM HD Surround
recordings and live events in surround sound. Neural Surround employs
psychoacoustic frequency domain processing which allows delivery of a more
detailed sound stage with superior channel separation and localization of audio
elements. Playback is selectable between 5.1 and 7.1 channels.
Sleep Timer: From
the remote, you can set the unit to automatically turn off after a preset amount
of time. The sleep timer can be adjusted from 10 minutes to 90 minutes in
Input Display: The name
displayed for most inputs is fixed (DVD, Video1, etc), but the Tape and Video2 input
displays can be
changed. Tape can be changed to MD, CDR, or HDD. Video2 can be changed to HDD.
Display Dimmer: The
display illumination has three brightness level settings.
Wireless Remote:The RC-649M remote is programmed to operate this unit and other Onkyo
equipment. The remote also includes the codes to control other brand DVD players
and recorders, CD players and recorders, MD recorders, TVs, VCRs, Satellite and
cable boxes, PVRs (Personal Video Recorders), TV/DVD combos, TV/VCR combos,
Satellite/PVR combos, and cable box/PVR combos.
The speaker terminals for the front left, front right, center, surround left,
surround right, surround back left, and surround back right are binding posts. A
plastic collar prevents using spade terminals, but bare wire, pin connecters,
banana plugs and dual banana plugs will work. The B channel outputs are spring

Subwoofer: The 230 watt powered subwoofer features a 10" front-firing woofer in a
bass reflex enclosure. The subwoofer has a single RCA line input for use with the
supplied cable. The subwoofer automatically turns on when an input signal is
received, and returns to standby mode when no signal has been input for about 5
minutes. An LED indicator on the front panel glows red when in standby mode and
green when in operation. The volume control is on the rear panel.
The front speakers each use a 1" balanced dome tweeter and two 5"
cone woofers in a bass reflex enclosure. Each speaker has a set of
spring clip terminals for use with the supplied speaker wire. Each enclosure has
a removable black cloth grille. The speaker's sensitivity is 86 dB (1 watt/1
meter), the crossover point is 4.5 kHz, and they are magnetically shielded.
