Pioneer SC-1523-K (USA version)

Overview

Pioneer SC-1523-K was introduced in 2013. It is equipped with 9 channel amplifier and is capable of 9.1 maximum channel processing.

We evaluated the Receiver and gave 85 overall score out of 100. Our ranking system is based on the amplifier specifications, audio and video features, connectivity, multizone capabilities, radio and many other details.

Amplifier score is based on power ratings, minimum impedance load, power supply, transformer type, total harmonic distortion, damping factor, signal to noise ratio and other small details. Audio score depends on the number of channels, front wide channel support, maximum channel processing, support of audio formats, DAC specifications, room calibration algorithm... Video score is based on HDR, Dolby Vision and video signal passthrough and upscaling, analog to HDMI upconversion. Connectivity score is defined from all wired and wireless inputs and outputs, internet and bluetooth connections, HEOS, SONOS and others. Multizone score depends on the number of zones with their outputs. Radio score is evaluated form digital radio support and analog tuner with its frequency range, signal to noise ratio, harmonic distortion...

Amplifier

Pioneer SC-1523-K has 9 channel Class D³ amplifier and delivers 135 W (8 Ω, 1 kHz, 2 channel driven) and also has a stable performance at 4 Ω load. This receiver even supports front wide channels which is found only in a very few high-end receivers these days.

Video Features

The Receiver has 4K passthrough up to 30p and 4K upscaling up to 30p.

Class D³ Amplifier

Pioneer Class D³ amplifiers contain advanced integrated circuitry technology creating unmatched power without sacrificing sound quality or performance. Class D³ amplifiers use a Direct Signal Path Design to provide the shortest audio signal path possible. By eliminating EMI filters, feedback loops, and current limiters of previous designs, Class D³ reduces ringing distortion and noise, especially in the high frequency audio band.

The power consumption of the Digital Class D³ Amplifier is significantly lower than traditional A/B amplifiers - letting you save energy and generate less heat without compromising performance. The Digital Class D³ Amplifier uses a simple structure employing a straight signal path, resulting in improved sound quality requiring less energy than competitive models yet producing more simultaneous power output. This direct signal path means no EMI filters, feedback loops or current limiting - a true engineering art. Unlike traditional designs, these amps deliver the strength to handle multiple low-impedance speakers without dramatic power loss. The efficiency of Class D³ means cooler operation while drawing just a fraction of the power consumed by conventional amplifiers, enhancing and extending component life and reliability.

THX™ Certification

Pioneer SC-1523-K is THX™ certified which offers optimal performance, superior quality and seamless integration. THX works with partners from the ground up, so that certified products deliver professional quality audio-visual experiences right out of the box. They only certify the very best products with uncompromised quality, performance and consistency. They ensure that THX certified devices play well with lower performing devices and components. THX listening modes make the receiver to have one speaker set up for movies, music and games. They are tested for power output, bass management, signal-to-noise ratio and feature RE-EQ, timbre matching, boundary gain compensation and THX Loudness Plus. The current model has Select™2 Plus class performance. This means that it is ideally suited for a room where the screen-to-seat viewing distance is approximately 3 to 4 meters, and the room size is approximately 56 cubic meters.

Advanced Sound Retriever

Compressed music enhancement in Pioneer SC-1523-K is done by Pioneer’s Advanced Sound Retriever. Hear the detail, warmth and clarity, the way the artist intended it, from all of your highly compressed MP3 and WMA files stored on USB, Smartphone and portable media players. By restoring data that tend to get lost in the digital compression process, Pioneers Advanced Sound Retriever Technology enhances audio reproduction all the way upto 20 Khz frequencies.

Room Correction

Pioneer SC-1523-K comes with Advanced MCACC room correction system and includes the calibration microphone.

Connectivity

Pioneer SC-1523-K can be connected to internet using ethernet cable or wirelessly via optional AS-WL300 adapter (sold separately). It can also connect to bluetooth devices via optional AS-BT100 or AS-BT200 adapters (sold separately). The Receiver supports AirPlay. It has 9 HDMI inputs and HDCP 2.2 copy protection. There are 11.2 channel analog pre-outs for external amplification.

Front panel has HDMI, USB and Composite Video inputs.
