Network & Tuner Functions
Symmetrical Designed Power Amplifier: The Onkyo CS-N755 is equipped
with a 13 watt x 2 channel amplifier. Its symmetrical and uniform layout
minimizes the chance of interference between left and right channels.
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.
3-Stage Inverted Darlington Circuitry: 3-Stage Inverted
Darlington Circuitry is a core Onkyo technology incorporating a low-NFB
(negative feedback) design that makes the sound more natural.
192kHz/24-Bit Audio DAC: The 192 kHz/24-bit audio DAC enables the best
possible reproduction of standard and high-definition audio formats.
VLSC (Vector Linear Shaping Circuitry): Conventional D/A
conversion methods reduce digital pulse noise at the conversion stage, but can't
remove it completely. Previously only found on higher-end components, VLSC
(Vector Linear Shaping Circuitry) employs a unique D/A conversion circuit to
overcome this problem. Data is converted between sampling points and these
points are joined with analog vectors in real-time to produce a smooth output
wave form. The result is a virtually noiseless, smooth analog signal based on
the digital source to bring out even the most subtle of nuances in your music,
movie soundtracks, and even MP3.
Advanced Music Optimizer: While compressed music files may sound fine
through the headphones of your portable digital player, the limitations of these
files can be exposed when played back through a quality home entertainment
system. This is because a significant amount of high-frequency bit information
is lost during the file-compression process. To counter this, Onkyo has designed
the Advanced Music Optimizer to compensate for lost bit information and improve
the quality of compressed audio signals. This results in a clearer and more
expansive sound. Also included in this technology is a loudness correction
feature that further improves the audio character of compressed files. The Music
Optimizer function only works with PCM digital audio signals with a sampling
rate below 48kHz and analog input signals.
Tone Control + Phase Matching Bass Boost: You can independently adjust
the Bass & Treble of the CS-N755 from -3 to +3 dB. Onkyo's Phase-Matching Bass
Boost technology effectively preserves midrange clarity, allowing vocals and
string instruments to sound natural while maintaining a smooth powerful bass
response at all volume levels.
Direct Mode: When the Direct Mode is activated, the tone controls are
bypassed, so you can enjoy the purest sound possible.
Analog + Digital Inputs: The Onkyo CS-N755 is fitted with both analog
and digital audio inputs. There are 2 stereo RCA and one minijack (3.5mm) analog
audio inputs. In addition, there is one optical and coaxial digital input.
Line Output: The CS-N755 is also fitted with an analog
stereo RCA output for connecting a recording device.
Binding Post Speaker Terminals: There are color-coded,
binding post terminals will accept bare-wire (up to 10AWG), pin-connectors, and
banana plugs (single/dual).
Subwoofer Preamp Output: There is a mono RCA jack for
connecting a powered subwoofer.
Headphone Jack: For private listening, the CS-N755 has a
front-panel 3.5mm minijack headphone output. When headphones are connected, the
unit's speakers are muted.
Two-Way Bookshelf Speakers: The CS-N755 comes with a pair of 2-way 4Ω
bookshelf loudspeakers. The speakers feature a 1" balanced, soft dome tweeter
and a 4" OMF (Onkyo Micro Fiber) woofer, loaded into a bass reflex enclosure
with a rear-firing port. The included black cloth grilles are detachable. The
speakers have binding post terminals that will accept bare wire (up to 10AWG),
pin-connectors, spade-connectors, and banana plugs (single only) and come
with two 6' lengths of speaker wire. Other speaker specifications include:
- Impedance: 4Ω
