QUICK START

We realize that you can’t wait to hook up your new Mackie Designs HRS120 High Resolution Powered Subwoofer and try it out.

Nevertheless, please take the time to read this page NOW, and the rest can wait until you’re good and ready.

The HRS120 has its own built-in power am- plifier. You should turn the INPUT SENSITIVITY control on the back of the cabinet down (fully counterclockwise) before turning on the HRS120 for the first time. Also be sure to set the power switch on the rear panel off (down). This will prevent you from accidentally connecting a hot signal source to the subwoofer and getting a rude surprise.

There are a number of other settings you can make on the back of the HRS120, and you can read about them later on in this manual so you really know what they do. For now, just leave all the switches out, and the CROSSOVER controls set to the center position (80Hz).

For stereo applications:

1.Connect the left and right line-level signal

from your mixer, preamp, or other signal source to the LEFT and RIGHT IN jacks on the HRS120 (XLR or RCA).

2.Connect the LEFT and RIGHT OUT jacks on the HRS120 (XLR or RCA) to the inputs of the left and right main powered speakers (or to the inputs of the amplifiers powering the left and right main speakers).

3.Connect the supplied AC power cord to the IEC socket on the back of the subwoofer. Plug the other end into an AC outlet properly configured with the correct voltage for your particular model.

For surround sound applications:

1.Connect the LFE (Low-Frequency Effects) or subwoofer line-level signal from your

mixer, preamp, or other signal source to the LEFT (MONO) IN jack on the HRS120 (XLR or RCA).

2.Set the FILTER BYPASS switch to the FULL RANGE position (pushed in).

3.Connect the supplied AC power cord to the IEC socket on the back of the subwoofer. Plug the other end into an AC outlet properly configured with the correct voltage for your particular model.

For stereo and surround sound applications:

4.Set the POWER switch on the rear panel to the ON position. The red POWER LED will turn on.

5.Turn on the power to the other components in the system.

6.Start your signal source (tape deck, CD, DAW, or whatever), but leave the master volume control on your mixer or preamp down.

7.Adjust the master volume on your mixer or preamp to a comfortably loud listening level.

8.Slowly turn up the INPUT SENSITIVITY control on the back of the HRS120 to its fully clockwise position (NORMAL), or until you achieve a balance between the subwoofer and the other speakers in the system.

9.Enjoy the authoritative, commanding lows of the HRS120.
