Speaker System Features
Inputs and Outputs Notes
Digital-to-Analog Converters: The HT-R340 receiver is equipped with
192kHz/24-bit DACs to decode and play high-resolution recordings.
iPod Compatible: The DS-A2 Remote
Interactive Dock for iPod (item number 580DSA2) provides 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 iPod's battery.
This receiver has a built-in crossover for the subwoofer output. This setting is
also used for any other speakers set 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-R340 has 3 assignable digital inputs (2 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 II, and DTS
processing, it also has a 5.1 multi-channel analog input for use with external
multi-channel decoders (DVD-Audio, SACD, etc).
Occasionally the audio and video signals are not properly synchronized,
typically when using a progressive scanning DVD player. You can correct this by
delaying the audio; options are 0 (no delay), 20, or 40 milliseconds.
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 main room is reduced to a 2.1 channel system
(front speakers and subwoofer).
Speaker Levels: Along with
adjustments for the front, center, and surround speaker levels,
the left and right 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
HT-R340 receiver has a 32-bit Analog Devices DSP and 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 Pro Logic II (Movie, Music, and
- DTS Neo:6 (Cinema and Music)
- 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 the Dolby Digital and DTS modes, plus the Dolby Pro
Logic II Movie and DTS Neo:6 Cinema 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.
Dolby Pro Logic II Music Mode: While
listening in the Dolby Pro Logic II 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).
OptiResponse Equalizer: When
using the HT-R340 with the included speakers, by turning on the OptiResponse
equalizer (OR EQ), you can enjoy a powerful sound with movies or music.
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
When playback is started on a component connected via the Remote Interactive
(RI) jack, the receiver automatically selects that component as the input
Input Display: The name
displayed for most inputs is fixed (DVD, CD, etc), but the Tape and Video 3
input displays can be changed. Tape can be changed to MD, CDR, or HDD and Video
3 can be changed to HDD. These settings also effect the Remote Interactive
(wired remote) codes output to other connected components.
Only one of the input labels can be changed to HDD.
Display Dimmer: The
display illumination has three brightness level settings.
The RC-646S remote is programmed to operate this unit and other Onkyo
components; including a cassette deck, DVD player, CD player, Mini-Disc
player/recorder, and CD recorder. When combined with the DS-A2 iPod dock the
remote offers basic control of your compatible iPod as well.
The speaker terminals are spring
terminals, they will accept pin connectors and bare wire up to 14 gauge.
Speaker System Features
