Mackie Recording Equipment MR5mk2 User Manual

MR5mk2

The MR5mk2 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 MR5mk2 is designed to operate with a +4 dBu sig-

nal 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. 

This 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 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.

This is where the signal is connected to the monitor 

and adjustments are made to the frequency response 
of the speakers to match the monitor’s location and the 
room’s environment. 

There are three types of input connectors: XLR,    

1/4-inch, and RCA. Since all three of them are  

 

connected together electrically, do not connect more 
than one signal at a time to the input jacks.

•  The XLR connector and 1/4-inch TRS (tip-ring-sleeve) 

connector accept a balanced signal while the RCA   
connector 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 may 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):
