HF Trim Switch
This control allows you to boost or attenuate (reduce) your SM50 monitors' high-frequency
response above 3 kHz. This switch can be set in the following ways:
•
0 dB: This default setting leaves high-frequency signals unaffected (high-frequency
sounds are neither boosted nor attenuated).
•
+2 dB: This setting boosts signals above 3 kHz by 2 dB.
•
-2 dB: This setting attenuates signals above 3 kHz by 2 dB.
To configure the HF Trim switch, begin by mixing a few songs with this knob set to the default
0 dB position. If your mixes sound good in the studio and on other speakers (car stereos,
"multimedia" computer speakers, etc.), leave this switch in the default position.
If your mixes sound good in the studio but they sound "dull" and lack high-frequency "sparkle"
on other playback systems, set the switch to -2 dB.
Alternatively, if your mixes sound good in the studio but sound too "crispy" or "brittle" and
contain too much high-frequency content, set this switch to +2 dB.
Setting this switch to either +2 dB or -2 dB allows the SM50 monitors to compensate for a
mixing environment that is either too "live" (i.e., too much high-frequency reflection from the
walls and other surfaces) or too "dead" (i.e., not enough high frequency sound is being
reflected around the room).
MF Boost Switch
This control engages a mid-range boost from 1 kHz – 3 kHz with a 2 dB peak at 2 kHz. The
switch can be set in the following ways:
•
Out: This default setting allows incoming signals to bypass the midrange boost
circuitry (the midrange of a signal is not affected).
•
In: This setting engages the midrange boost circuitry and creates a 2dB peak at 2
kHz with a 1 kHz bandwidth (i.e., signals between 1.5 kHz – 2.5 kHz are boosted).
To configure the switch, leave the switch set to the Out position and mix a few songs. If you
notice your mixes sound good in the studio but the midrange tends to be too prominent (e.g.,
the vocals/guitars are too loud) on other speakers, set the knob to In. This will make the
midrange of your SM50 monitors slightly more pronounced in the studio and will result in more
balanced mixes since you will be less inclined to "push" the midrange of your mixes.
LF Cutoff Switch
This control allows you to engage a high-pass filter that removes low-frequency sounds from
the monitors. This switch can be set in the following ways:
•
Flat: This default setting allows your monitors to play their entire frequency
spectrum with no low-frequency filtering.
•
80 Hz: This setting engages a second-order (12 dB/octave) filter that rolls off
frequencies below 80 Hz.
•
100 Hz: This setting engages a second-order (12 dB/octave) filter that rolls off
frequencies below 100 Hz.
If you are using your SM50 monitors with a subwoofer that does not have a built-in crossover,
set this switch as close as possible to the low-pass cutoff frequency of your subwoofer. The
low-pass cutoff of the subwoofer should be listed in the "technical specifications" section of
the subwoofer's User Guide.
If your subwoofer has an internal crossover that sends high-frequency signals out to your main
monitors through a pair of outputs, leave the LF Cutoff Switch on your SM50 monitor set to
Flat.
Tip: Many subwoofers feature a low-pass cutoff frequency of 80 Hz. If you are not sure about
your subwoofer, use this setting as a starting point.
Tip: The Low Cutoff switch can can also be engaged if you wish to hear what your mixes
would sound like on speakers with smaller woofers (such as those found in most televisions).
