Conversely, if your mixes are consistently too bright,
then adding some additional high-frequency energy in
the monitors satisfies your ears, and the resultant mix
has less HF content.
The timbre of your monitors affects
the way that your mixes play on other
equipment. Remember that the
monitors have a mirroring effect on
the mix; if the monitors make
something too loud in the mix it usually results in not
enough of that thing on tape.
Start with the response modification switches in the
factory recommended settings (see Quick Start
Section). After prolonged listening, if you notice a trend
in your mixes, perhaps making some small adjustments
as suggested here will help.
It’s a real rush to mix really loud. But remember that
the resulting mix only sounds good when you play it at
least that loud. However strange it may sound, mixes
made at lower levels sound even better when played
loud; perhaps even a bit bigger than life.
Get that sound level meter out. Decide what level
you’re going to mix at and use the meter to help keep
your mixing at that level. Your ears will thank you, and
your mixes will be better for it.

This 3-position switch turns the amplifiers on or off, or
sets them to automatic mode. Use this switch to set the
HR824 MK2s to your preferred mode of operation, and
use the front panel power
[9] switch for convenience.
• In the STANDBY position, the power amplifiers are in
Standby mode and produce no sound. Low-level circuitry
is still active, but the power consumption of the
circuitry is minimal (8 watts).
• Flip the switch to the ON position and the power
amplifiers are live and operate normally. (The front
panel power [9] switch must also be IN.)
• When it’s in the AUTO ON position, the amplifiers turn
on and off depending on the presence or absence of an
input signal. An input signal level of –45 dBu
(minimum) activates the auto-on function. A silent
period greater than eight minutes activates the
auto-off function. The power ring [10] on the front
panel reflects the state of the amplifiers.
