REAR PANEL DESCRIPTION
. INPUT LEVEL
The MR5 expects 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 MR5 is 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.
. HIGH FREQUENCY FILTER
The HIGH FREQ switch tailors the overall high-
frequency response by ±2 dB at 5 kHz and above. 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.
This is where you connect your signal to the monitor,
and make adjustments to the frequency response of
the speakers to match the monitor’s location and your
room’s environment.
1. SIGNAL INPUTS
There are three types of input connectors: XLR (bal-
anced), 1/4-inch (balanced), and RCA (unbalanced).
Since all three of them are connected together electri-
cally, do not connect more than one signal at a time to
the input jacks.
• The XLR connector and 1/4-inch TRS (tip-sleeve-ring)
connector accept a balanced signal while the RCA con-
nector accepts an unbalanced signal. A balanced signal
provides better noise rejection and is the preferred
method, especially if using a cable longer than 20 feet
(6 meters).
• The 1/4-inch TRS jack can also accept an unbalanced
signal from a 1/4-inch TS (tip-sleeve) plug.
The connectors are wired as follows (per the AES/IEC
standard):
XLR TRS RCA
Hot (+) Pin 2 Tip Tip
Cold (–) Pin 3 Ring —
Shield (Ground) Pin 1 Shield Shield
See Appendix B: Connectors, for more information on
these connectors.
