METER SELECT

The Meter select switch allows the user to monitor either Gain Reduction or the Output level of the unit. When the 
switch is engaged and illuminated, the output of the particular channel you are monitoring is visible in the 
corresponding VU Meter. 

POWER SWITCH

The Power Switch glows a soft amber color when an IEC power lead is connected to the unit. This indicates that 
the unit is connected to the AC main supply and the ELOP+ is in STANDBY mode. Engaging the power switch takes 
the ELOP+ out of standby mode and into warm-up mode. The power switch will illuminate to a brighter amber and 
the backlit VU meters will start to flash. This warm-up process last 30 seconds after which the MUTE relays will lift 
and the VU meters will stop flashing.

LINK / STEREO FUNCTION

When the LINK function switch is engaged and illuminated the ELOP+ applies the same amount of gain reduction to 
both the left and right channels. This is done to prevent image shifting that can occur if each channel is 
compressed individually. It becomes noticeable when a loud element that is panned to either edge of the stereo 
field raises the level of the program to the compressor's threshold, causing its image to shift toward the center of 
the stereo field.

We suggest that when in LINK mode both channels have their controls set the same. It requires the user to use both 
sides, so that the limiters react equally based on whichever side has the loudest peak. 

When in LINK mode there is no “Left Channel Master”. Each control still works independently of each other.
STEREO is used on stereo tracks so if either channel is called to limit. This prevents image shifts and an instrument 
should stay where you panned them.

You should generally stay in STEREO mode if using the unit to limit or compress two different mono tracks, such as 
vocal in one channel and guitar in the other. 

Note that when in LINK mode, the mode of operation for the ELOP+ for either a LIMITER or COMPRESSOR must be 
set the same for both channels. Switch (6), Diagram 1. If one channel is set to LIMIT and the other set to COMPRESS 
this will stop the unit functioning correctly in LINK mode.
