Here is my question
I have a new construction in which i am running the final wires for the ht system
My Home Theater system consists of the following
Center Channel: Magnepan MMG-C (5 ohm speaker)
Front Left and Right Speakers are Speakercraft Time 3 Speakers
Rear L & R are Speakercraft AIM8 Three
Velodyne dd-10 Subwoofer
Emotiva upa-7 amplifier
emotiva umc-1 receiver (which i just ordered and have not yet received)
most of the wiring and installation has been done, in regards to the speakers and hdmi cables
Here is my dilemas:
Velodyne says you can use the XLR input or preferred is the
"Establish the line-level connection (optional). Connect to a pre-amplifier’s main outputs and
returning them to your amplifier inputs. When installed in this fashion, your satellite speakers
will be crossed over at 80Hz, which removes the lower bass from your amplifier and
speakers, enabling them to do a better job reproducing high frequencies. By utilizing this
method, you will have a bi-amplified system, gaining improved power and headroom for
your system"
Emotiva states that their preferred method is the Sub out using the XLR connector (balanced output, or the sub out rca jack on the 7.1 outputs 2nd best)
and fyi, the the cable run from the processor to the sub is about 20-25 feet, so my understanding it is best to use xlr?
the magnepan manual says the following
PROCESSOR SETTINGS
Set your receiver or processor on "small" speaker for the center channel, and "large" or
"full range" for the left/right speakers. (This does not apply if the MC1 or MMG W are
used as front left/right speakers.) Set the MMG C crossover point at 100Hz. Try higher
crossover points to achieve natural reproduction of male voice. Depending upon your
room conditions and the center channel placement, a different crossover point from
100Hz may be needed.
Even though you will probably be using a subwoofer, set your receiver or processor for
"no subwoofer." This may seem strange, but it is necessary for the proper integration
of the center channel bass. To drive your subwoofer, use a pre-amp output from the
front left/right of the processor or receiver. (It may be necessary to use Y adapters.)
How (and why) this setup works-normally, when "small" center speaker is specified,
the center channel bass is routed to the subwoofer. In reality, this doesn't work very
well, especially for Magneplanars. There is usually a frequency "hole" in the response
or the sonic integration is poor. When "no subwoofer" is specified, the processor
automatically routes the center channel bass to the front left/right "full range"
Magneplanars (because there is no alternative). The front left/right Magneplanars
provide the bass for the center channel speaker; and the integration is seamless,
having the same characteristics as the MMG C.
Since the signal from the front left/right pre-amp outputs is "full range," the subwoofer
receives all the bass information. The .1 channel (effects) is not needed. Adjust the
subwoofer crossover point so it does not overlap with the "full range" front left/right
Magneplanars.
and the speakercraft three in the rear allow you to adjust the ohm's from 8, 6 or 4)
How should i connect to the subwoofer ? using the XLR?
coax? rca? Should i use the sub out or feed the full range into the velodyne? do i return the signal back to the umc-1 at 80hz?
and the magnepans. i know they are power hungry and how do i set them up!
do i run the full range signal to them, ?
do they need to be bi-amped. is there a way to get more power to that channel compared to the others?
i have different configurations and i'm not sure what to do! help!
help! was i foolish for getting the magnepans?
i also didn't want to leave out wiring in the walls. i want to make sure that i have to run xlr or coax or whatever, that it is done now before we drywall!
