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 equip-
ment. Remember that the
monitors have a mirroring
effect on the mix; if the monitors make some-
thing 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 lis-
tening, 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 re-
member that the resulting mix only sounds
good when you play it at least that loud. How-
ever 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 HR624s to your preferred
mode of operation, and use the front panel
mute
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 (12 watts).
• Flip the switch to the
ON
position and the
power amplifiers are live and operate
normally. (The front panel mute
switch
must also be OUT.)
• 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 –74 dBu (minimum)
activates the auto-on function. A silent
period greater than eight minutes activates
the auto-off function. The green power
LED on the front panel reflects the state of
the amplifiers.
