Rotel Releases a New Audiophile Pre/Pro (RSP-1582)

Following several years of detailed development, Rotel Electronics has unveiled a new sharp looking preamplifier and surround processor. The 7.1 channel pre/pro is loaded with high-end touches, but carries a relatively modest high-end MSRP of $3,499. Today we’re previewing the RSP-1582 and highlighting a few of its more significant features.



The front panel of Rotel's new RSP-1582 features a nifty 7-inch TFT screen.


Enthusiasts look to pre/pro units for one result: the highest quality of sound reproduction. According to Rotel, that’s exactly what they hope the RSP-1582 delivers. The company says that its engineers “painstakingly” evaluated every circuit design in the unit to streamline performance and eliminate interference.

The heart of the RSP-1582 is comprised of six 24-bit/192-kHz Wolfson Microelectronics WM8740 digital-to-analog converters (DACs). Four of the WM8740 DACs are dedicated to front sound stage (LCR) and subwoofer channels, with the remaining two handling rear and surround channel duties. Rotel also integrated a Texas Instruments PCM1804 analog-to-digital converter (ADC). Users can select a bypass function that eliminates the DSP section, creating a pure analog signal path.

The RSP-1582 uses a Texas Insturments Aureus TMS320DA808 chip to decode multichannel soundtracks. The unit ships with support for Dolby TrueHD and DTS-HD Master Audio codecs. Currently, it does not offer Dolby Atmos or DTS:X decoding. According to Twice, Rotel says a future upgrade will enable Atmos functionality.

On the video side, the RSP-1582 houses a Silicon Image Sil9573 2K/4K HDMI Transceiver to allow 4K video pass-through. It also has two HDMI 4K pass-through outputs (one of which is ARC/CEC enabled). It’s worthy to note that the RSP-1582 does not currently carry HDCP 2.2 protection, which means it won’t be able to manage HDCP 2.2 protected 4K content. This isn’t an issue now, but could become an issue as streaming 4K content becomes more prevalent.



A gorgeous maze of connection options on the backside of the RSP-1582.


A total of eight rear and one front 4K HDMI inputs were included for nearly limitless source connectivity. Users will also have access to three optical, three coaxial, and one PC-USB digital input, in addition to a phono stage, XLR balanced, and six stereo analog inputs. Analog pre-outputs include balanced XLR, unbalanced RCA, and twin subwoofer connections. A front-panel USB input supports charging connected Apple devices and can be used for firmware updates.

The RSP-1582 comes in either a black or silver finish. It's front panel features a slick looking 7-inch color TFT display. Rotel says it will ship sometime during March or April of 2015.

Just stinks right now buying new pre/pro gear with all the HDMI spec changes and whatnot. I took the suffer now route until things stabilize.

Re: Rotel Releases a New Audiophile Pre/Pro (RSP-1582)

Usually there are give and take buying years...but this is a pretty significant one. The good news is that firmware updates are possible. The biggest question is: which items on your want list can be addressed by firmware upgrades?

Not sure of the feasibility of this...but it would be nice to have a manufacturer produce a HDCP 2.2 external decoder...perhaps a standalone unit...or maybe a dongle of some kind. Not sure if the industry would like low cost decoders floating around, but it would help to eliminate that issue.

This is definitely a good year to wait it out IMO. Lots of really nice equipment and exciting technologies coming into the market but too many unknowns that are likely to be answered in the next 6-12 months. Take a breather, tweak your acoustics, upgrade your sub, but let us be the guinea pigs that test the waters with the new electronics. I don't know how plausible it would be to get our hands on a Rotel unit. Very very nicely made gear though from my experience.

Peter, aside from Atmos/DTS:X and HDCP 2.2, do you have any other tech omissions that makes you weary on the new gear hitting the market?

Generally speaking I would add UHD/4k (plus any related potential changes to Blu-ray) and the various new (or new-ish) flat panel display technologies. IMO a nice 7.1 system with a Blu-ray player and good quality 1080p display can produce a really incredible home theater experience. Anything beyond that serves to improve or, shall we say, "enhance" that experience but will likely only appeal to a small percentage of consumers. I personally don't find any of the new tech to be gimmicky, but I also don't feel like any of it is a must-have. The tricky part now is that in some cases the software and hardware are developing at different rates, and many of these new features require updates or additions to one or both. Neither of which is cheap. I look at it more like the mobile phone industry now. Either be happy with what you have, or if you must upgrade, know that there will almost certainly be a new and improved version available within a year or so.

Agreed. Considering I just purchased my gear and got my system going and KNOWING about all this stuff in the air particularly this year with all the changing going on I decided to stick to a budget system. BUT, after watching Fury last night I can tell you that the 1080P and 5.1 is truly a great experience and I already know if it impresses me then 95% of the people coming over to view will be just as impressed.

Sure... 4k/atmos/etc will all add a nice touch but will be a costly investment for 10% better performance.

I should have thrown UHD/hdmi 2.0 in there...

I agree with you...a well calibrated HD 7.1 system should go a long way. That said, I am completely intrigued by HDR tech in displays...less intrigued about more pixels. Atmos/DTS:X are high on my upgrade list, but I'm thinking your suggestion of waiting it out might be a good one. Seems like some obvious holes still exist.

Excellent comment! I will test the HDMI 2.0 and HDCP 2.2 waters with a new Nvidia GTX 960 video card...$200 tops - that's not a lot to spend

Re: Rotel Releases a New Audiophile Pre/Pro (RSP-1582)

It seems strange that a high end, high priced AV equipment would not have the latest decoders etc. All of the missing items are available on currently shipping products. I wonder how much "painstaking" care went into the design?
