Locomotive Audio Power-Mu 500 Series Stereo Compressor

The perfect companion for your stereo bus

The Locomotive Audio Power-Mu delivers smooth tube compression on stereo sources. With its stepped knobs, you get precision control and easy recall, saving you valuable time in your mixing sessions. While it shines at gentle gain reduction, it can also be pushed into deeper gain reduction for a rich, harmonic presence. This full-featured 500 series compressor provides ample control, making it a versatile tool for any audio professional.

TRANSFORMERS

Custom interstage transformers allow for smooth compression without harsh artifacts

AC & DC THRESHOLD

These threshold controls work together to set compression onset, knee and ratio, giving abundant control over tube drive

TUBES

Each channel uses a NOS dual triode for true vari-mu compression and tube harmonics

SIDECHAIN LOW CUT

Cut low frequencies from the sidechain in order to prevent unwanted compression

STEPPED CONTROL

The stepped 21-position knobs on the Power-Mu allow for performances to be recalled with precision

HARDWIRE BYPASS

This switch allows the user to toggle between original and affected signals

STEREO LINK

Force the same gain reduction on the left and right channel to stabilize the center image

POWER SWITCH

Save tube life and 500 series chassis power by turning off the power when not in use

The Power-Mu Experience

Full control of gain staging, harmonics, compression threshold, and ratio are at the heart of the Power-Mu experience. Input and output controls allow you to decide how much audio level you would like to send through the unit. The AC and DC threshold controls determine when compression kicks in, and what kind of compression knee is obtained. Lower DC threshold settings will have a softer onset of compression, while higher DC threshold settings will have a harder knee with limiting characteristics.
