Thermal Protect

All amplifiers produce heat. The HR824 MK2 is de-

signed to be efficient both electrically and thermally. 

•  If for some reason the heatsinks get too hot, a thermal 

switch activates, placing the HR824 MK2 into Standby 
mode (indicated when the power ring [10] turns off).

•  Should this happen, make sure that airflow to the rear 

of the cabinet is not restricted.

•  When the heatsinks cool down to a safe temperature, 

the switch resets and normal operation resumes.

Integrated Magnetic Shielding

The HR824 MK2 Studio Monitor contains drivers 

with large magnet structures. The drivers’ magnets are 
shielded to help prevent the magnetic field from radiat-
ing out into the environment and playing havoc with 
computer monitors or TV screens. Unshielded speakers 
can cause distortion in both the shape and color of the 
picture if placed too close to a CRT (cathode ray tube). 
If you have a particularly sensitive computer monitor or 
TV screen, it may be necessary to move the speakers a 
few inches away.

Input Signal Wiring

You should use high-quality, shielded cable to connect 

the signal source to the SIGNAL INPUT jack [1] on the 
HR824 MK2. 

•  Foil shielded cables, such as Belden 8451, 8761, or 9501 

are commonly used for studio wiring.

•  Microphone cables work well.
•  The better the shield, the better the immunity from 

externally induced noise (like EMI and RFI). Route the 
cable away from AC power cords and outlets. These are 
common sources for hum in an audio signal. Wall warts 
and line lumps are especially insidious hum inducers!

  You can purchase quality cables from your Mackie 

dealer. 

•  In certain home theater applications, it may be nec-

essary to connect the speaker outputs from a stereo 
receiver to the inputs of the HR824 MK2s, if the receiver 
doesn’t have preamp outputs or other line-level output 
connections.

CAUTION:

 Do not attempt to con-

nect a speaker output directly to the 
input of the HR824 MK2! Speaker 
levels are much higher than line lev-
els and can damage the input circuitry 
in the HR824 MK2.

You can, however, insert a speaker-level to line-level 

signal attenuator between the receiver’s speaker output 
and the HR824 MK2’s input. Your Mackie dealer may be 
able to help you find one, or you can build your own.

CARE AND CLEANING

Remove the protective plastic film that encases the 

cabinet.

Note:

 You may leave the protective 

plastic film on the cabinet if you 
wish, or you can remove all but the 
side that will be in contact with the 
surface it is sitting on to protect the 

finish. Also, you should save the protective plastic film 
to reapply to the cabinet in case you need to move it to 
another location (or return for servicing).

The piano-black finish on the HR824 MK2 cabinets is 

exceedingly beautiful, yet extremely delicate. Clean the 
outside of the cabinet with an optical grade non-scratch 
cloth, such as you would use to clean eyeglasses, CDs, or 
DVDs.
