DIDRC (Dynamic Intermodulation Distortion
Reduction Circuitry)
Reduction Circuitry)
Since the advent of digital audio, signal-to-noise ratios have
improved dramatically. However, the S/N ratio reflects static noise
only, and takes no account of another type of noise that occurs as
the byproduct of sound reproduction—dynamic noise. To reduce
this type of noise, Onkyo has developed DIDRC technology for
use in our hi-fi components. Despite being beyond the normal
range of human hearing, frequencies above 100 kHz are
susceptible to clock pulse and other forms of distortion from
digital devices. Such distortion in the super-high-frequency range
can generate “beat interference”, which in turn affects the
character or atmosphere of the original sound. By improving
linearity and reducing distortion in the super-high-frequency range,
Onkyo’s new DIDRC technology effectively reduces perceptible
noise and delivers clearer-than-ever audio.

Separate Digital/Analog Circuitry and Transformers
To prevent unwanted interference, the P-3000R employs
physically separate circuitry for digital and analog processing.
What’s more, it also features separate transformers for digital and
analog circuitry.

Playback of Various Music Sources Including PC
Audio via USB
Audio via USB
The P-3000R pre-amp accepts analog sources such as records and
tapes, along with digital output from iPod via a digital media
transport such as Onkyo’s ND-S1. Using the USB device (C-Media
CM6631) on the rear panel of the P-3000R, you can also connect
your PC and play back 192 kHz/32-bit HD audio formats*.

PLL (Phase Locked Loop) Ultra-Low Jitter
Technology
Technology
Jitter is an unwanted side-effect of the digital-to-analog conversion
process caused by fluctuations in the time domain of a digital
signal. PLL ultra-low jitter technology reduces jitter by comparing
the input and output phases of the digital signal and creating an
accurate clock waveform. This enhances the precision of digital
signal processing and noticeably improves perceived audio quality.

Separate TI Burr-Brown DACs for L/R Channels
High-quality TI Burr-Brown DACs work to optimize analog audio
performance on Onkyo’s new hi-fi components. The P-3000R
pre-amp sports dual 32-bit PCM1795 DACs, which support
sampling rates of up to 192 kHz, display high resistance to clock
jitter, and handle a 123 dB dynamic range. Although these DACs
can process two-channel audio on a single chip, Onkyo employs
separate chips for each stereo channel, to ensure the most
accurate digital-to-analog conversion.

Bi-Amping Capability
The P-3000R pre-amp offers the audiophile possibilities of bi-
amping. Compatible speakers can be bi-amped for separate
powering of high and low frequencies. Using the bi-amping mode
on the P-3000R gives you greater control of the frequency
balance.

Audiophile-Quality Parts
The P-3000R incorporates a massive toroidal transformer for the
analog circuitry that reduces magnetic flux leakage, improves
efficiency, and keeps the power supply stable. For the digital
circuitry, meanwhile, it employs a high-quality EI transformer.
Gold-plated, machined solid brass, 19 mm-pitch terminals ensure a
clean connection and help prevent interference between thick,
high-quality cables. Meanwhile, Amphenol AES/EBU digital inputs
provide resistance to signal degradation and noise.

New Circuit Board Construction
Rather than being directly connected to the chassis base, the
circuit boards inside the P-3000R are cushioned by internal struts
and affixed to the front, side, and rear panels. This method of
construction prevents vibrations from the chassis from adversely
affecting the circuit boards.

Separate Panel Construction
The P-3000R features separate aluminum panels for the top, sides,
and front to reduce unwanted vibrations caused by internal
resonance. Compared to a one-piece chassis design, this
construction method offers greater rigidity and improved noise
reduction.
