Manley ELOP+

Acting like a brilliant volume control over vocals, bass, and tons of other sounds, the Manley ELOP+ is their redefined electro-optical compressor/limiter bringing with it clear and smooth dynamic wrangling. Inspired by the fan-favorite LA-2A, the ELOP+ brings two channels of Manley's optical dynamic control with all-tube amplification and output staging, made with their high-voltage design for extreme amounts of headroom. Starting out, the ELOP+ takes in a balanced XLR signal, applies Manley's famous IRON transformer, and then sends the signal on its way to the compression stage.

On the front panel, you have a very simple layout for controlling the actual compression and limiting applied: reduction and gain. Each channel applies individual controls for each, but putting the ELOP into Linked mode via the Link/Stereo button applies equal gain reduction across both channels! Whether you're using the ELOP+ as a compressor with a 3:1 ratio or a limiter with a 10:1 ratio, the dynamic control never darkens the sound and keeps the highs bright and alive. Each channel additionally has control for a 1-pole high pass filter at 80Hz to apply to the sidechain circuit for cleaned up ducking and dynamic control, and level-matching or mix referencing is easy with the per channel hardware bypass buttons.

Whether you run it in stereo, series mono, or dual mono, you'll be sure to get premium compression and limiting with a fantastic and full tube sound from Manley's ELOP+.
