Executive Overview

One of the great features you can't deny about separates is that if you like your amplifier you can always change out your pre/pro for the latest technology. Audio company Rotel is leveraging this idea so that consumers can get the latest surround sound processing without buying a whole new receiver. Last week at CEDIA, San Diego, Rotel introduced the RSP-1576 Surround Sound Processor.  The RSP-1576 is a multi-channel preamplifier that is capable of decoding all popular audio formats and comes with 2 DSPs and an array of 6 Wolfson 24/192k audiophile grade DACs. The processor supports configuration options from 5.1 to a complete Dolby Atmos or DTS:X 7.1.4 home theater. There are 12 channels of RCA audio outputs for a fully customized installation.

Rotel is known for quality home audio and theater solutions at an accessible price point, and this new surround sound processor follows suit. The RSP-1576 has been expertly designed and engineered for music and movie lovers alike to offer maximum performance and flexibility.

The new processor includes HDMI 2.0a 4K/UHD 60Hz HDR video, Audio Return Channel, aptX CD quality Bluetooth wireless streaming and dual Texas Instruments DSPs supporting Dolby Atmos and DTS:X.


The architecture of the RSP-1576 includes individual audio and video processing circuits with careful attention to signal routing. The sonic circuits were tuned by Rotel’s acoustic engineering team to further ensure the processor accurately reproduces audio from the dynamics of blockbuster movies to the subtle nuances buried deep within an orchestral concerto. The array of source inputs include coaxial (3), optical (3), PC-USB (24/192k), iPod, aptX Bluetooth, XLR Balanced, RCA Analog and Moving Magnet phono stage input for vinyl enthusiasts.

Custom installers will appreciate the full array of customization options including RS232 and IP control, IR remote receiver input, IR remote repeater outputs, 10 band parametric EQ for room equalization and software updates available via the front USB or over the Internet. The setup menu is available on both the HDMI output and on the integrated VFD display, providing easy access to all configuration options.

Note: We are glad to see the inclusion of PEQ as some companies still employ GEQ (Graphic Equalizers) which are far less effective at tuning out problematic room modes. PEQ allows for adjustable frequency and bandwidth whereas GEQ which has limited usefulness.

 What we think

With over 50 years of experience in the audio industry, Rotel has the know how and ingenuity to handle the processing needed for today’s surround sound applications. We would like to have seen Auro-3D included in this processor, but the inclusion of top notch DACs and individual tuning by Rotel’s expert engineers should guarantee a processor worthy of your upscale home theater. The RSP-1576 is currently shipping at a suggested retail price of $2,399
