Front panel operation and Remote Control Functions 

 

The mPRE is very simple to operate from the remote control or front panel. A 

power button with an illuminated ring light is located on the lower right portion of 
the front panel. When the mPRE is plugged in and the rear power switch is in the 
“on” position the ring light will be green when in standby. To turn the unit on, press 
the power button on the front and the ring light will then change to blue.  

There are 6 input select buttons on the front located on either side of the 

volume knob. To change inputs simply press desired input button or use the remote 
control to scroll through the inputs. The mute feature can be activated by using the 
remote control and can be pressed at any time to silence the analog outputs or the 
headphone output. The volume knob has a position indicator and with one turn, the 
mPRE can be adjusted from minimum to maximum output.  

 

The LED brightness level can be adjusted by using the following procedure: 
 

1.

 

Ensure the unit is in standby by pushing the power button located 
on the front panel. (Standby is indicated by a green illuminated ring 
light) 

2.

 

First press and hold the AUX 2 input button in, and then power the 
unit on from standby by pressing the power button.  

3.

 

Once the unit is on you can release the AUX 2 button. Press the AUX 
2 button to toggle through the brightness settings which will be 
previewed by the LED that is lit. 

4.

 

When you have found the setting that you prefer turn the unit off 
using the power button on the front to apply it. 

 

Special note: Aux 2/HT bypass and Variable/Fixed Out are selected by a 2 position 
switch. We will define “in position” as when the switch is pressed in and the 
button is nearly flush with the back of the unit. The “out position” will be defined 
as when the switch is in the extended position and not flush with the back of the 
unit 

 

Aux 2/Home Theater Bypass 

 

          The mPRE can be easily integrated into your Home Theater system 

when using the selectable HT bypass. The switch to activate HT bypass is located on 
the left side of the rear panel indicated by #14 on the back panel diagram (pg. 8). 
When the switch is in the “out position”, Aux 2 is a standard analog input. When the 
2 position switch is in the “in position” Aux 2 becomes the HT bypass input. If this is 
your desired function of the Aux 2 input it can be left in this position. When HT 
bypass is in use, the signal from your processor (or equivalent device) will pass
