6. Input Level
The MRmk3 studio monitors expect a line-level signal
at its input. Use this control to adjust the sensitivity of
the input section according to the signal strength at its
input.
• The MRmk3 studio monitors are designed to operate
with a +4 dBu signal when the input level control is in
the max position. In other words, wide open.
• Refer to the Quick Start section on page 5 for the
level-setting procedure.
7. Custom-Tuned Rear Port
The custom-tuned rear port uses the radiation from
the rear of the woofer cone to extend the low-frequency
response of the speaker. The size of the port is carefully
designed with respect to the volume of the cabinet
and the characteristics of the woofer to produce
low-frequency extension.

8. Running Man Logo LED
The Running Man logo illuminates when the power
switch [2] on the back of the MRmk3 studio monitor
is turned on and AC power is available at the mains
input [1].

4. Low Frequency Filter
This switch tailors the overall low-frequency response
by +2 dB or +4 dB at 100 Hz.
• For most applications, use the “0 (NORMAL)” setting.
This takes the equalization circuit out of the signal path.
• If a little extra low-frequency output is necessary, use
the +2 dB setting.
• If even more low-frequency output is necessary,
use the +4 dB setting. Remember how things work in
reverse, so boosting the deep bass content on playback
may actually decrease it in the final mix.
5. High Frequency Filter
This switch tailors the overall high-frequency
response by:
±2 dB at 3 kHz and above [MR5mk3]
±2 dB at 3.25 kHz and above [MR6mk3]
±2 dB at 3 kHz and above [MR8mk3]
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 the mixes consistently sound dull or dark when
you listen elsewhere, this usually indicates that the
monitors are too bright, relative to your normal hearing.
A bit less high-frequency energy usually fixes this, and
the mix may be forced in this direction by reducing the
high-frequency output of the monitors by using the –2 dB
position of the switch.
Conversely, if the 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.
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 to
mix at and use the meter to help keep mixing at that
level. Your ears will thank you, and your mixes will be
better for it.
