LD Systems PRE 2 Overview

Ideal for smaller installations, the LD Systems PRE2 is a compact two-channel line and mic mixer that allows you to mix stereo audio from any media source with a microphone for announcements. The unit is incredibly easy to use with two simple volume control knobs, with signal presence and clip indicators.

The built-in audio ducking function automatically reduces the music level from the stereo line input when an announcement is being made. Connect a wired remote for simple master volume control. Dip switches let you configure it to work in stereo or mono mode. With its tine form factor and included mounting plates, the PRE2 can be installed discreetly behind screens or under tables. Alternatively, it fits into a quarter 19" rack, while an optional rack tray is available to slot up to four products alongside each other and build a system to your exact requirements, using minimal rack space.

  • 1× balanced stereo line input
  • 1× mic input with gain control and –20 dB pad switch
