Dear FMs,
Was just wondering if it is possible to hack an AVR without pre-outs to provide preamp signal to be fed to an external amplifier. After some R& D came across the following 2-3 options to get it done:
1. Surgery- open the AVR , find the signal path between preamp and amplifier board and solder a wire from the preamp FL, FR and ground out to an unused RCA port on the back of the AVR. However considering the price of an AVR it is difficult for most of us to use this option although it can be easily be done by FMs with some tinkering experience. The result will be the same as having pre-outs to an otherwise sealed AVR.
2. Use a High Level - Low Level converter: this is something which is used in car audio to connect an external amp to a factory fitted car amp without pre amp outs.
The converter basically converts the high wattage speaker signal to low wattage signal which can be safely fed to another amplifier. However I am not sure if this device meant for car audio can handle a large wattage signal coming from an AVR meant for center/ FL/FR (don't mind the use of technical words such as wattage since I don't belong to "that" field)
3. Use a professional converter such as Behringer DI 4000- for about INR 3,900 (for 1 channel) to about INR 9,000 (for 4 channels), this seems like a viable option. The only requirement will be that of a XLR to RCA converter to feed the output to the RCA ins of a power/ integrated amp.
If we can use any of the 3 methods above then there won't be a need to buy expensive AVRs (except for more channels). We can simply add power amps and run the show.
There is not much of material on the above approach. If any of you have tried these methods or have comments on what could work please let me know.
Thanks !
