Anybody tried this? The attraction would be to take advantage of the Room Perfect and sub-woofer integration capabilities of the 1120. The 1120 has line level outputs as well as speaker level ones. The line level outputs max out at 4Vrms, so not enough to drive an F4 to maximum output, but maybe enough for fairly sensitive speakers. The full amp does 60 wpc into 8 ohms ie more than 20v so more than enough for full output from the F4.
