Mackie MR8 Benutzerhandbuch

MR8

The MR8 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 MR8 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.

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.

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):
