Active (Tri-Amped) Design
The Sage Cinema Hybrid Line Source is designed to be tri-amplified. There are no
passive crossover components inside the speaker; instead, there are direct
connections from the amplifiers to their respective drivers.
When using an external active crossover like the Wisdom Audio SC-2/3, three sets of
speaker wires are required for each Sage Cinema Hybrid Line Source loudspeaker:
one pair for the woofer (low) section, a separate pair for the planar magnetic (mid)
section that handles the midrange, and a third pair for the high frequency module
(high).
We recommend using heavy-gauge speaker wire, the gauge will vary dependent on
your speaker run length. Please consult an authorized dealer to determine what
gauge would be best for your application.
For the purposes of this manual, we will assume that you have already connected the
SC-2/3 System Controller as per the instructions found in its manual. As such, you
should have signal coming from your source component(s) to a preamp/processor,
and then on to the SC-2/3; following the SC-2/3, the signal is split into low, mid, and
high sections, with the low section going to one Wisdom Audio SA Series amplifier
channel which will drive the woofer drivers, the mid section going to a second SA
series amplifier channel which will drive the planar magnetic panels, and the high
section going to a third SA Series amplifier channel, which will drive the high
frequency module.
•
Connect the outputs of your Wisdom Audio SA Series amplifier to the center
module input terminal binding posts, taking care to get both the channel
assignments and the polarity correct. Connect the positive (+) terminal on the
woofer amplifier to the positive (+) terminal for the Low Pass on the
loudspeaker; like- wise, connect the negative (
–
) terminal on the woofer
amplifier to the Low Pass terminal on the loudspeaker, respectively.
•
Repeat this process for the Mid and High Pass section on the center module.
•
The center module has fly leads to connect to either side of the center for each
line module that flank the center.
