Hi all! Long-time casual lurker here & a mild enthusiast for low/mid-level audio gear. I recently acquired (locally) an interesting amp on FB marketplace (while browsing for used speakers LOL). It's an old but fully functioning NAD-906 3-channel amp (release year: 1992), each of the three independent stereo power amplifiers within the 906 has its own pair of inputs and outputs.
Base Specs:
* Continuous Average Power Output into 8 OHMS (Min. power per channel, 20 Hz - 20 kHz, both channels driven with no more than rated distortion) ==> 30 W (14.8 dBW)
* Rated Distortion (THD 20 Hz - 20 kHz) ==> 0.05%
* IHF dynamic power (maximum short term power per channel)
> 8 ohms ===> 48 W (16.8 dBW)
> 4 ohms ===> 65 W (18.0 dBW)
> 2 ohms ===> 85 W (19.3 dBW)
This is a very beefy amp, heavier than my new Yamaha A-S701. Currently, I got it hooked up in Bi-amp configuration, driving Mordaunt Short MS912 speakers. This setup is sounding really good by the way, just as good as the Yammy (I think)
Channel-1 pair is wired to the speaker's HF connectors, while Channel-2 pair goes to LF. Channel-3 is not in use, but I'm thinking of putting Channel 2 & 3 in bridge mode... then connecting it to the speaker's LF, that way the amp can supply more power to drive the woofers as needed. Essentially, HF would have 30 watts on tap, while LF 60 watts(?)
My question is: with the double amount of amplification power on tap for the woofers (versus the tweeters), does this mean the volume (as I listen to music) would be "louder" on the LF channel (woofers) and thus it would cause an imbalance to audio between HF & LF?
