them over the ends of the speaker and remove the two wooden
constants from the top of the subwoofer. Disengage the caster
brakes. With one person on either side carefully and slowly roll the
subwoofer off of the crates based, down the ramp and onto the
floor.
3. Install the Magico DSP Control Software from the supplied CD to
your PC or Apple computer
4. Hook up your QSub
You will need a 20amp C19 IEC power connector. Connect the
output(s) from the Preamp to the Ch. 1 XLR input connector (mono)
or both, Ch.1 and Ch. 2 XLR input connectors (stereo). Connect a
USB cable from your computer to the subwoofer. Make sure that the
subwoofer’s power switch is in the down (off) position. Plus in the
power cord, make sure that your source is on with a minimal volume
setting and your can switch your QSub ON. (You can a find a more in
depth description of all of the connections on the rear panel as
well as the capabilities when configured via ethernet connection to a
network later on in this manual)
!
5. Position your QSub(s)
We will start by measuring the QSub bass frequency response.
We will try to optimize the QSub location so we will have smooth
frequency response up to 100Hz while trying to minimize the dips in
the frequency response. Follow the instructions of your
measurement software to take SPL measurements of the subwoofer
alone from a microphone placed at ear height in the listening
position.
Start by placing your QSub between your main speakers. if this is not
possible, try to place it near one of the corners behind your main
speakers. Measure it at the first location. Begin by making
incremental movements (6 inches at the time) both in relation to the
side and back wall until you get the smoothest response from the
subwoofer in a reasonable position in the listening environment.
Try to compare your measurements using overlays:
You can overlay them all under the “All SPL” tab. Now deselect
them all. You can do this by right clicking over the legend area. You
can choose which to overlay, making it easier to analyze the results.
