Locomotive Audio Power-Mu 500 Series Stereo Compressor
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.
