The ELOP+ Electro-optical Vacuum Tube Limiter/Compressor from Manley Labs supports 3:1 compression ratio that makes this compressor suitable for 2-buss applications. It features a vacuum-tube line amplifier and white-follower output stage. The compressor is housed in a build-efficient chassis behind a precision-CNC-milled faceplate. It also features a high-voltage switching power supply designed for Manley Labs' vacuum-tube audio circuits.

10:1 limiter and 3:1 compressor ratios
All-tube audio path uses 5751 and 6922 dual triodes
Balanced Manley IRON transformer-coupled XLR inputs
XLR impedance-balanced outputs
BYPASS switches and AUTOMUTE with warm-up delay
Large illuminated VU meters read gain reduction or output levels
STEREO LINK
Sidechain high-pass filter
Universal internal power supply
