A-9150 Integrated Stereo Amplifier

THIS PRODUCT IS FOR ONLINE ORDER ONLY. A-9150 Integrated Stereo AmplifierTake Music Further with True FidelityBuilding on acclaim for the award-winning A-9010 Onkyo again raises the bar for musicality in the entry class with its A-9150 Integrated Stereo Amplifier. Unique technologies coalesce around a refined amplification system to deliver outstanding transient response superb dynamics lifelike soundstaging and nuanced articulation of your favorite analog or digital music. Key to this sense of realism is Discrete SpectraModule which boasts a slew rate of more than 500 V/µs for flat linearity up to megahertz bandwidth. Rediscover the vitality of analog with MM/MC phono input served by dedicated equalizers on a separate circuit board with custom head-amp operating in discrete configuration for MC signals. Listeners with big CD libraries will discover new life in the format with AKM's premium 768 kHz/32-bit DAC (AK4452) enhanced by DIDRC Filter an original circuit technology that cleanses signals of high-frequency noise. Backed by 70 years' experience in hi-fi design the A-9150 invites you inside the energy of every musical performance.HIGHLIGHTSRefined Power Amplification Circuitry with Discrete SpectraModuleDedicated MM/MC Circuit Board and High Quality Discrete Head AmpHigh Current Power SupplyNatural Music Reproduction with Hi-Grade DAC and DIDRC FilterRobust Flat ChassisQuality Audio TerminalsRefined Power AmplificationIn order to deliver a clear and comfortable audio image it's vital that sounds of different frequencies arrive at the listening position simultaneously. Power amplification circuits feature original topology that's carefully tuned for phase accuracy wide-spectrum signal reproduction and natural transient response. Fitted with hand-selected audio-grade parts the amplifier contributes to lifelike and involving sound quality. Nuanced Musicality Delivered with Discrete SpectraModuleDiscrete SpectraModule boasts a slew rate of over 500 V/µs significantly higher than competitive products that use a standard IC chip. High-voltage performance enables flat linearity into the megahertz range for full-bandwidth signal reproduction. This is important not only for natural transients expressing the nuances in music with freshness and vitality but also for accurate definition of instruments ranged around a larger and more realistic soundstage.Dedicated MM/MC Phono Circuit BoardThe A-9150 makes your records sound better than ever. A gold-plated phono input supports signals from either MM or MC cartridges fitted to your choice of turntable. Separate phono circuit board has dedicated equalizers served by a top-quality customized head amp which operates in discrete configuration for MC signals. Together with analog power amplification this high-grade phono input design expresses the depth and vitality of music on vinyl.Customized High-Current Transformer and Custom Audio-Grade CapacitorsCurrent has great influence on sound quality. High current is required for a better grip on the speaker transducers improving control and accuracy. A customized high-output transformer and two huge custom capacitors inside the A-9150 deliver current through discrete output-stage transistors that are kept cool by an aluminum heat sink. Speakers react instantly with throw-range precisely controlled for accurate articulation even through dynamic and complex musical passages.DIDRC Filter and Hi-Grade DAC for Natural SoundDistortion in the ultra-high-frequency spectrum can have a noticeable impact on the character of audible sound. Even the best D/A converters introduce some noise to the signal and that noise is amplified distorting the sound you hear. DIDRC Filter completely erases ultra-high-frequency noise. Performance is optimized for digital music with an undistorted frequency response extending far above the range of audibility. Combined with a premium 768 kHz/32-bit DAC you can enjoy a greater sense of realism from digital sources with none of the unnatural synthesized feeling sometimes produced by digital processing. Solid Build with High-grade TerminalsA peek under the hood tells you what to expect from the A-9150. Held in place by a flat chassis that tames resonance the digital audio board is isolated from the analog circuitry. L/R channels are symmetrical to equalize signal path-lengths and minimize stereo playback errors. Coaxial digital inputs phono input speaker posts and RCA line inputs are gold-plated and of excellent quality. Finished with an aluminum front panel and volume control the A-9150 presents as a component built to last.ADVANCED FEATURES60 W/Ch (4 ÃŽ© 20 HzË€ 20 kHz 0.08% THD 2 Channels Driven IEC)Discrete SpectraModule Produces High Instantaneous Voltage for Immersive Soundstaging Improved Instrument Separation and Lively Transient ResponseDIDRC Filter Prevents Ultra-high-frequency Distortion Affecting Audible SoundHigh Current Power Supply Transformer and Two Hi-Grade Customized CapacitorsHigh-Current Low-Impedance Drive for Enhanced Speaker ControlOptimum Gain Volume Control Circuitry Isolates Signal from Noise Floor to Prevent Distortion at Lower VolumeSymmetrical L/R Channel Layout with Equal Signal-path Lengths to Minimize Stereo Playback ErrorsIsolated Processing Pre-amplification and Power Amplification Circuitry Reduces Electrical Interference on Audio SignalLarge Extruded Aluminum Heat SinkAKM (AK4452) 768 kHz/32-bit Digital-to-Analog ConverterDirect Mode for Reproduction Faithful to Original SourceFront-panel A/B Speaker Drive SelectorINPUTS AND CONNECTIONS4 Gold-plated Analog RCA Audio Inputs (Rear)2 Optical Digital Inputs (192 kHz/24-bit Capable)2 Gold-plated Coaxial Digital Audio Inputs (192 kHz/24-bit Capable)2 Pairs of Gold-plated Speaker Posts (A+B)Gold-plated Phono Input (MM/MC) to Suit Any Turntable6.3 mm Headphone JackGold-plated Main InputGold-plated Pre OutRI (Remote Interactive) Remote Control InputADDITIONAL FEATURESTone Controls (Bass/Treble/Balance)Aluminum Front Panel and Aluminum Volume Control KnobRigid Steel Chassis to Reduce ResonanceStable Isolator Feet Minimize Vibration-borne InterferenceEfficient 0.2 W Power Consumption on StandbyFull-sized and Full-function RI Remote Control SPECIFICATIONSPower Output 60 W/Ch (4 ÃŽ© 20 HzË€ 20 kHz 0.08% THD 2 Channels Driven IEC)THD+N (Total Harmonic Distortion + Noise)0.08% (20 Hz20 kHz Rated Power)Input Sensitivity and Impedance200 mV/220 kÃŽ© (Line)4.0 mV/47 kÃŽ© (Phono MM)0.4 mV/120 ÃŽ© (Phono MC)Rated RCA Output Level and Impedance0.2 V/2.3 kÃŽ© (Line Out)Phono Overload (MM) 70 mV (1 kHz 0.5%)Phono Overload (MC) 7 mV (1 kHz 0.5%)Frequency Response 10 HzË€ 100 kHz / +1 dB -3 dB (Line 1 Direct)Tone Control ±10 dB 100 Hz (Bass)±10 dB 10 kHz (Treble)Signal-to-Noise Ratio 107 dB (Line 1 IHF-A)Signal-to-Noise Ratio 82 dB (Phono MM IHF-A)Signal-to-Noise Ratio 73 dB (Phono MC IHF-A)Speaker Impedance 4 ÃŽ©16 ÃŽ©Headphone Output Impedance390 ÃŽ©GeneralPower Supply AC 220230 V~ 50/60 HzNo Sound Power Consumption35 WPower Consumption 160 WStandby Power Consumption0.2 WDimensions (W x H x D) 435 x 139 x 331 mmWeight 9.2 kgCARTONDimensions (W x H x D) 572 x 264 x 419 mmWeight 11.5 kgSupplied AccessoriesInstruction manual AC power cord Remote controllerAAA (R03) batteries x 2
