Removing the low-frequency content also allows
you to raise the overall output level somewhat. Low-
frequency information requires the largest amount of
an amplifier’s output, so restricting the low-frequency
content allows raising the mid-frequency level some-
what. If your client insists on mixing LOUD, this may be
a workable strategy.

The HIGH FREQ FILTER switch tailors the overall
high-frequency response by ±2 dB beginning at 10kHz.
Leave this switch in the 0 (NORMAL) position unless:
• You want to subtly brighten or darken the sound of the
speakers.
• Perhaps you have hearing loss caused by too many
nights in front of a double Marshall stack.
• You just like to mix on the bright side or dull side.
If your mixes consistently sound dull or dark when
you listen elsewhere, this usually indicates that your
monitors are too bright, relative to your normal hearing.
A bit less high-frequency energy usually fixes this, and
you can force the mix in this direction by reducing the
high-frequency output of the monitors by using the –2 dB
position of the switch.

The LOW FREQ FILTER switch inserts a low-frequency
rolloff into the response curve.
• For some applications, the low-frequency output of the
HR824 MK2 may impair your ability to make mix judge-
ments.
• For THX applications, use the 80Hz setting.
• For non-THX applications where a sub-woofer isn’t en-
hancing low-frequency output use the 37Hz (NORMAL)
position.
• The LOW FREQ switch affects the low-frequency con-
tent of your mix. Remember how things work in reverse,
so removing the deep bass content on playback may
actually increase it in the final mix.
• You can use the LOW FREQ switch’s 80Hz position to
simulate a smaller loudspeaker, especially one with
limited low-frequency capability (like a certain popular
2-way nearfield monitor). You may need to do this if a
small speaker is the eventual destination of your mix,
or perhaps just to see how your mix sounds on a clock
radio.
