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 somewhat. If
your client insists on mixing LOUD, this may be
a workable strategy.
HIGH FREQ
HIGH FREQ
0
(NORMAL)
– 2dB + 2dB
The HIGH FREQ switch tailors the overall
high-frequency response by
±
2 dB 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.
LOW FREQ
LOW FREQ
37Hz 80Hz 47Hz
LOW CUT (NORMAL)
The LOW FREQ switch inserts a steep low-
frequency rolloff into the response curve.
• For many applications, the low-frequency
output of the HR824 may impair your ability
to make mix judgements.
• For most applications, use the 47Hz setting.
• If you want or need the extra low-frequency
capability, by all means use the 37Hz
(NORMAL) position.
• The LOW FREQ switch affects the low-
frequency content 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 destina-
tion of your mix, or perhaps just to see how
your mix sounds on a clock radio.
Removing the low-frequency content also
allows you to raise the overall output level
