HR624 MK2

24 MK2

Feel free to experiment.

In many respects, every room is unique in terms of its 

acoustics.

Even after you’ve read about how to set the HR624 

MK2’s rear panel switches, try other settings to see if 
your particular room environment requires different 
adjustments.

And, even after you’ve placed your monitors where you 

think

 they’ll sound best, try moving them around. You 

might be pleasantly surprised.

Finally, keep an open mind about  

improving your room’s acoustics  

and bass-handling ability.

Nobody likes to buy a new set of monitor speakers 

and then be told that they should spend extra bucks on 
bass traps or a remodeling job. But the simple fact is, 
“standard” rooms, i.e., rectangular rooms in  
conventional business or residential structures, are 
rarely if ever conducive to optimal low bass  
reproduction without some modifications.

Luckily, there are plenty of options short of building 

a new control room, many of which are covered in this 
manual.

Additional Tidbits of Wisdom

•   When you shut down your equipment, turn off the 

HR624 MK2 studio monitors first to prevent thumps 
and other noises generated by any upstream equipment 
from coming out the speakers. When powering up, turn 
on the monitors last.

•   Save the shipping box! You may need it someday, and 

you don’t want to have to pay for another one.

•  Save your sales receipt in a safe place.
•  Also record all HR624 MK2 serial numbers in the space 

provided on the next page, along with where and when 
you bought them.

Placement

The HR624 MK2s were designed to be placed in a 

vertical position. If you find it necessary to place the 
speakers in a horizontal position (on their sides), place 
them so that the woofers are toward the inside; that is, 
so the woofers are closest to each other. This provides 
the best low-frequency summing and overall imaging.

The HR624 MK2s may also be wall-mounted using 

the mounting hardware located on the bottom of the 
cabinet. These are currently designed to be used with 
the OmniMount 60.0 WB (Wall-to-Bottom) wall-mount 
bracket, which provides a wide range of horizontal and 
vertical movement to meet your coverage requirements. 
However, many companies change specifications  
without notice. Please refer to the OmniMount website 
and contact their team for more details:

When the monitor is operated at high sound pressure 

levels, a fair bit of heat can be generated by the internal 
power amplifiers. These internal amplifiers are part of 
the rear panel electronics assembly. To ensure adequate 
ventilation, the rear of the monitor should be placed at 
least three inches away from the wall.

Note:

 The Mackie logo can be rotated 90º so 

that it is oriented correctly when placing the 
speakers on their sides. Gently pull out on 
the Mackie emblem, rotate it, and push it 
back into place.
