About This Listing

The SPL MS Master 1020 is a powerful mastering and mixdown tool which allows for independent processing of central ('mid') and ambient / differential elements ('side') of a stereo signal. Its on-board filter, Mid-channel balance control, FLOAT process & comprehensive monitoring and metering features make it stand out among M/S matrix units.
  • Fully analog L/R to M/S encoding & decoding interface with independently switchable insert paths.  
  • Elliptic filter in Side signal with stepped control – for clarity & vinyl cut compatibility.
  • Active control of M/S mix ratio = stereo width.
  • Switchable inserts for outboard gear in M & S channels (or L & R in LR mode).
  • ALPS "Big Blue" potentiometers & gold-coated mechanical relays.
  • Hard bypass: insert routing works even when the power is cut off.
  • Independent level controls for M & S – note that this function is not implemented in SPL's new Gemini MS processor.
  • Absolutely unique: Set the L-R balance position of the Mid channel without shifting the overall stereo image! 

  • Comprehensive monitoring section w/ independent insert & mute switches
  • VU-meter modes: M/S & L/R, PPM & -10dB switches.
  • FLOAT function for retaining mono compatibility at extreme settings, or for easier insert processor setting (during monitoring).

Application examples:
  • Stereo image enhancement of stems / sum during mixdown, corrections after mixdown, or in mastering / vinyl cutting applications.
  • Reverberation & ambience reduction without loss of brilliance or clarity. Independent processing of spatial, out of phase sounds without affecting central elements or transients, and vice versa.                                                      
  • Save $$: Use a mono / single channel compressor on the Mid signal, and leave the Side signal uncompressed for punch while retaining a natural ambience. (MS processing is 100% phase-neutral – no issues when inserting FX in one channel)
  • Use different EQs / settings on M & S channels to get warmth + clarity at the same time (for instance: Pultec-type passive EQ on M for low & high shelving enhancement, and a neutral parametric EQ for precision resonance notching on S).
  • Smash dynamics on Side elements without affecting center transients. Or grab those transients without getting the ambience punched. Saturate the ambience, keep percussive elements crystal clear... Unlimited possibilities.

Works perfectly. Cosmetics: Moderate marks from rack mounting and use. Comes with original box and power cable (EU plug). 115-230V switchable. Requires change of fuse for 115V operation (easy to replace through compartment on the back).
