Mackie HRS150 Manuale Utente

4

We realize that you can’t
wait to hook up your new
Mackie Designs HRS150
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 HRS150 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
HRS150 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 HRS150, 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 

CROSS-

OVER controls set to the center position (80 Hz).

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 HRS150 (XLR or RCA).

2. Connect the 

LEFT and RIGHT OUT 

jacks on the HRS150 (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.

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 HRS150

(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 HRS150 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 HRS150.
