HR624 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.

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.

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.

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.
