Smooth, sleek and singularly capable

How can you simultaneously look streamlined, minimalist, and be amazingly capable? Ask Onkyo. They've clearly done it with their P-3000R stereo preamplifier. Well-outfitted to welcome all your digital and analog audio sources, this sleek preamp features careful attention to the details. Digital and analog signals travel separate paths through the component, and are powered by separate transformers that cater to the different characteristics the signals exhibit.

From A to D

First, the analog side of the equation. A large toroidal transformer powers the analog circuitry, which features 4 line-level inputs and a moving-magnet phono input. On the output side, dual preamp outputs can be set to bi-amp mode so that you can feed low- and high-frequency signals to separate amplifiers.

The P-3000R stands ready for a wide variety of digital sources, as well. Its asynchronous USB input allows you to feed computer music files to the two TI Burr-Brown DACs (1 for each channel), bypassing your computer's sound card for exceptional sound quality. The DACs accept high-resolution files up to 192 kHz/32-bit resolution from your PC (you'll need some dedicated software, downloadable from Onkyo's website).

A balanced digital XLR input provides reliable, low-noise connection from compatible high-end and pro gear. And of course, there are two optical and two coaxial digital inputs for easy interconnection with HDTVs, Apple® TVs, game consoles, and more, and there's even a digital optical output — for even more system design flexibility. Because of all the attention paid to your digital signals, all those sources will sound their best when converted and presented to a power amp downstream.

The Onkyo P-3000R Stereo Preamplifier

The Onkyo P-3000R features build quality you can hear

Build quality you can hear

Separate panel construction and strut-mounted circuit boards help to defeat distortion-inducing vibration. Gold-plated brass RCA jacks show you they're dead serious about their build quality. Attention to detail ends up being something you can hear, as inadequate/incomplete connections are one of the most common causes of signal degradation.

Your music — without compromises

Finally, Onkyo features a technology called DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry), which reduces the component's susceptibility to ultra-high frequency interference from digital devices that can create perceivable noise in your overall signal output. The final result of this drive for perfection? The music you love, clean, robust, and dynamic — without a hint of compromise.

Product Highlights:

  • separate TI Burr-Brown digital-to-analog converters (DACs) for right and left channels process digital signals for minimal jitter

Features

Preamplifier: The Onkyo P-3000R is a two-channel pre-amplifier which handles both analog and digital sources. Add Onkyo's M-500R Stereo Amplifier (580M5000R, sold separately) for an exceptional HiFi 2ch audio system.

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.

Separate Digital/Analog Circuitry & 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. 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, it employs a high-quality EI transformer.

New Circuit Board Construction w/ Internal Struts to Reduce Vibration: 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 TI Burr-Brown DACs for L/R Channels: High-quality TI Burr-Brown DACs work to optimize analog audio performance. The P-3000R pre-amp employs dual 32-bit PCM1795 DACs, which support sampling rates of up to 192kHz, 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

DIDRC (Dynamic Intermodulation Distortion 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. 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 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, truer audio.

PLL (Phase Locked Loop) Ultra-Low Jitter 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.

Controls

Tone Control: The P-3000R pre-amplifier provides Bass (50Hz), Treble (20kHz), and Balance control.

Direct Mode: When the Direct mode is activated, the tone controls are bypassed and the front-panel display is turned off, so you can enjoy a higher fidelity sound.

Sampling Rate Conversion: You can convert the sampling rate of the digital audio input signal.

  • FS x2: Outputs the input sampling rate by converting it to x2.
  • FS x4: Outputs the input sampling rate by converting it to x 4.
  • Bypass (default): Outputs the input sampling rate at the original sampling rate.
Note: If the sampling rate is greater than 192/176.4kHz, the sampling rate conversion will not be applied.

Remote Control: In addition to its front-panel control, the P-3000R comes with an IR remote control for wireless operation of the preamplifier. The remote is also pre-programmed to operate an Onkyo compact disc player (such as the C-700R, sold separately).

LCD: The Onkyo preamplifier features a front-panel LCD which indicates source and menu status. The LCD offers an adjustable dimmer (Normal, Dim or Off).

Auto Standby: The preamplifier will automatically enter Standby mode if there is not operation for 30 minutes with no audio signal input.

Connections

Left & Right Pre-Outs: The Onkyo P-3000R is equipped with two pair of RCA preamp-outputs (labeled 1 & 2) to connect an external power amplifier. Use Pre-Outs 1 for normal connection to a single external power amp, or both Pre-Outs 1 & 2 for a bi-amp connection to two separate external amplifiers.

CD/Line1/Line2 Inputs: The Onkyo P-3000R offers three sets of stereo RCA inputs labeled CD, Line 1, or Line 2.

Tape Input/Output: The Tape Input/Output consists of stereo RCA inputs and stereo RCA outputs. These jacks allow you to connect a tape recorder, CD-burner, or Equalizer.

Balanced XLR AES/EBU Input: This is a professional digital audio interface. Balanced XLR AES/EBU cables are used for better noise immunity and longer cable runs. The maximum sampling rate for a 2ch PCM input is 192kHz/24-bit.

Optical Inputs/Output: Optical digital connections allow you to enjoy 2ch PCM digital sound. The maximum sampling rate for 2ch PCM input is 96kHz/24-bit. Two inputs and one output jacks are provided.

Coaxial Inputs: The two coaxial digital inputs allow you to enjoy 2ch PCM digital sound. The maximum sampling rate for a 2ch PCM input is 192kHz/24-bit.

USB Port for PC Audio: Using the USB (type-B) port on the rear-panel of the P-3000R, you can connect your Windows PC or Mac computer and play back 192kHz/32-bit HD audio files. Playback of PC audio requires dedicated software that can be downloaded from Onkyo's website.

Phono Input: The Onkyo preamplifier is fitted with a Phono input and ground terminal for connection of a turntable (MM).

Headphone Output: When headphones are plugged into the full-size 1/4" jack on the front panel, the left & right pre-outs are automatically muted.

Remote Inputs/Outputs: The P-3000R contains RI Control and 12V trigger remote connections.

  • RI Remote Control Jack: The 1/8" RI remote control jack allows you to connect this preamplifier to other compatible Onkyo components.
  • 12 Volt Trigger Output: The 12V trigger  output can be used to turn on a 12V trigger-capable component automatically when it is selected as the input source.
