I have the PM6006 but the scrooges at Marantz haven't provided a sub out with it either.
Won't that require me to modulate the volume manually every single time i increase decrease the volume?
Method 2?
I didn't realise sending a line level signal taxed the amplifier. Does it mean that the REL T9i (active sub) that i have connected to my amp through line level is draining power. If so, is it a negligible amount or is it affecting the power draw of my speakers?
The Pm5005 is also like the 6006.no dedicated sub out. Hence the 'jugaad'
I think when u connect line level, the volume level amplitude is controlled by the amp. So to my mind, a seperate controller may not be required.
If u look at the circuit design, the amp module shares the output between speakers. So when I have 1 set of speakers connected, it gets full draw from the amp. When I connect 2 sets of speakers, the amp output is split between the 2 pairs since there is only 1 amp for both speaker A and speaker B. As for your query, since u have the 'active' REL sub, as u rightly mentioned, the power draw is negligible. Had the sub been a passive one, the single amp module would have to do double duty of powering speakers and sub. In your set up, the amplification is done within the amp of the sub, so no worries there.
In my case, being a small room, I have the volume set for the sub and speakers do most of the work. The sub only fills in the very low end at a moderate volume. In my room, room modes get activated so having the speaker close to the wall gives deep audible rumbly bass. For the feel in the gut, the sub comes in. Specifically in my room, if the sub wasn't controlled, it gets very boomy (read upset wife and complaining neighbours)
