Your dARTS powered subwoofer(s) are specifically designed to blend well with the dARTS main
speakers, and to perform well with either music or movies, augmenting the deep bass which is such
an integral part of our emotional involvement with our entertainment choices. Although very deep
bass is essentially non-directional, the higher bass frequencies and the initial attacks of each note
are often shared by the main speakers. Thus, subwoofers usually blend best when they are relatively
close to the front channels. The Audyssey Laboratories MultEQ XT room calibration software WILL
account for sub placement (as it does for all speakers) while measuring your room and designing the
correction curves, but the closer you can come to ideal placement, the better will be the results.
System Wiring and Connection
The dARTS subwoofer comes with an external 700-watt power amplifier. To connect the subwoofer,
run a shielded audio interconnect from the “SUB OUT next to input 8” on the SX7000 amplifier to the
“LINE INPUT” jack on the A2 subwoofer amp. Connect the speaker outputs on the A2 amp to the
speaker input terminals on the subwoofer. If you have more then one subwoofer use a Y connector
on the SX7000’s Subout jack.
The heart of the dARTS system is the SX7000 digital amplifier/controller. It consists of a 16-chan
-
nel power amplifier (up to 250 w/ch), the setup firmware used by Induction Dynamics to individually
match your speakers to each other (frequency response, crossover, time alignment), and space for
the room correction program your installer will run to calibrate the system to your room. Each of your
speakers will connect to the SX7000 with either two or three pairs of speaker wire. Your surround
processor or receiver’s preamp outputs will also be connected to the SX7000. If desired, your installer
can connect a 12 V DC trigger to the amplifier’s “POWER CONTROL IN” jack using the included trig
-
ger adapter. This will run from your surround processor or your automated control system to turn the
amplifier on and off. There is also a “POWER CONTROL OUT” jack available to pass on the control
voltage to another component in your theater system. The following tables show how each channel’s
wiring is connected to the amplifier/controller’s input and output terminals:
