all i want lang naman, since my AVR doesnt have a Sub In (Yamaha RXV-490) I dunno where to put it in this AVR..
all it has are Left/Right/Center/Surround Left/Surround Right. You can place 2 Front Left and Front Right because there is this speaker switch thingie. i hope you guys get it..
So what you need is a bass management system. You have a number of options. Unfortuantely, your prologic receiver does not sport preamp-output or main-in power input to allow you to use the options. These options essentally will insert an analog bass management module like the OUTLAW AUDO ICBM or the DBX 120A Subharmonic Synthesizer between the preamp and the power amps of your receiver. While you can use the tape record monitor L and R output, you would need an outboard stereo power amplifier.
Either options would most likely cost you about the same as getting a new HT receiver.
But if you have a sub that has L and R speaker level or high level inputs and satelite L and R speaker output. You can do this:
Connect the powered sub's low level L and R speaker input to your receiver's corresponding L and R front out and let the sub do the crossover selection. Then connect your L and R front speakers to the sub's L and R satellite speaker output. The sub effectively filters the lows out of the input signal and routes (low-passes) that to the sub's amp and speakers. Then it sends a high-passed signal to your main L and R speakers. Hope this helps.
