Ended up being simply wondering when it is feasible to hack an AVR without pre-outs to supply preamp sign become given to a outside amplifier. After some R& D came over the following 2-3 choices to take action:
1. Surgery- open the AVR , discover the alert course between preamp and amplifier board and solder a cable through the preamp FL, FR and ground down to an unused RCA port on the rear of the AVR. Nevertheless taking into consideration the cost of an lovoo AVR it is hard for most people to utilize this choice though it can be easily be achieved by FMs with some experience that is tinkering. The effect would be the just like having pre-outs to an otherwise AVR that is sealed.
2. Utilize an advanced level – Low degree converter: this really is something is employed in automobile sound to get in touch a outside amp to a factory fitted automobile amp without pre amp outs. The converter essentially converts the high wattage presenter sign to low wattage signal that can easily be properly given to a different amplifier. Nevertheless I’m not certain that this revolutionary product designed for vehicle sound are designed for a large wattage sign originating from an AVR intended for center/ FL/FR (do not mind the usage of technical terms such as for example wattage since I have do not participate in „that“ field)
3. Make use of a specialist converter such as Behringer DI 4000- for about INR 3,900 (for 1 channel) to about INR 9,000 (for 4 stations), this appears like an option that is viable. The only requirement will be compared to a XLR to RCA converter to feed the production into the RCA ins of a energy/ integrated amp.
Whenever we may use some of the 3 techniques above then there defintely won’t be a necessity to get high priced AVRs (aside from more networks). We are able to merely include energy amps and run the show.
There isn’t a lot of product in the above approach. If any one of you have got tried these methods or have actually commentary about what might work please let me know.

It sounds interesting to incorporate pre-outs to an AVR (if it is possible).. Guess, it could require an experienced individual to achieve that (or) a person who understands electronic devices perfectly. though we have never tried your idea,.
Best of luck, and keep us published on which you determine to do..

Surely well well worth an attempt if it is your extra receiver sitting idle. If you don’t, far better to get an older marantz nr series with pre outs and commence experiencing the movies faster.

Positively worth an attempt whether it’s your free receiver sitting idle. If you don’t, safer to get an older marantz nr series with pre outs and begin enjoying the movies faster.
The passive high to voltage that is low arrived yesterday. We connected it towards the front left and front right speaker outs of this Denon 2500H receiver. The outputs of this converter had been attached to the RCA ins (CD) regarding the Rotel RA 10 amplifier. The leading Left and Front Right Speakers were attached to the Rotel’s FL and FR terminals. We disconnected other speakers from the AVR to make certain that i possibly could do a little critical listening and comprehend distortions in noise if any.
I carefully fired up the AVR as well as the Rotel with both dials (volume) at Nil and played a Vinyl via a TT attached to the Denon AVR. First we increased the Denon amount slowly to see then turned up the Rotel to about 9 o clock if there were any temperature spikes anywhere (heat) and. I happened to be happily surprised to be greeted by sweet music. No distortion- humming or hiss of every kind. There was clearly a small increase in low end plus some glow during the end that is top. I happened to be astonished by the bass since I experienced never ever heard my bookshelves create such bass before. Nevertheless it was not fatiguing or overwhelming one other frequencies. I became hearing music extremely critically yesterday and checking conditions associated with the AVR, Rotel & most notably the passive converter. The Rotel ended up being somewhat hot all over heatsinks plus the Denon ended up being starting to warm up somewhat. we was hearing music for nearly 2 hours from Jagjit Singh to Bob Dylan to Bollywood songs streamed from Amazon music yesterday.
After 2 hours, the Rotel stayed hot not hot. The AVR had been warmer but i suppose it was as a result of continuous 2 hrs usage and the converter ended up being since cool as a cucumber.
Impressions regarding noise in basic:
1. Small uptick in low frequencies- which included definitely towards the experience. 2. silence that is complete hiss- hum 3. extremely wide soundstage- often going beyond your speaker width 4. Vocals were crystal clear- in fact in certainly one of the songs i really could feel Kumar Shanu operating away from breathing in the bottom end 5. Vocals seemed elevated through the remaining portion of the sound field and I suggest literally- focused but somewhat gaining in height- have no idea should this be good or bad but sounded good.
Cons: 1. AVR continues to be utilising the amp section (cant bypass this unless the AVR is opened by me and bypass the amp) 2. The sign goes through 2 preamps- the Denon along with the Rotel. This can continue unless we link energy amp.
I am going to continue to try this for a lengthier duration and then purchase another one when it comes to center channel
