    INTRODUCTION THANK YOU!... for choosing the Manley Laboratories Stereo Variable Mu Limiter Compressor. This unit has ® been our best selling product for many years. It is one of the very few compressors that has be- come a real standard in Mastering studios and contributed to most hit records over the last decade and probably the next.

    FRONT PANEL ADJUSTMENTS Initial basic settings for line level use: -Begin with POWER ON, BYPASS, SEP and COMPRESS -Set all controls at 12:00 ( or THRESHOLD at min) (for calibration feed in a 1Khz oscillator at 0 VU and confirm the return from the unit is actually 0 VU. Switch from BYPASS to IN and adjust the individual OUTPUTs to also return 0 VU.) -Switch from BYPASS to IN and adjust the INPUT LEVEL to get 3 to 6 dB of gainreduction on the meter with either COMPRESS or LIMIT.

  • Page 10: Operation Notes

    OPERATION NOTES The “MANLEY STEREO VARIABLE MU LIMITER - COMPRESSOR” is designed for multiple purposes. The unit can be used stereo or as 2 individual channels of limiting or compression. It can be used as a balanced line amp capable of 24 dB! of gain and as a pre-amp for low level signals. . With higher input gain settings the unit can be used to create gentle tube distortion if desired.

    NOTES ON MASTERING MODIFICATIONS The Mastering Version of the Variable MU Limiter Compressor uses expensive Greyhill rotary switches with gold contacts where conductive plastic pots were used. The steps are determined with a large number of 1% precision metal film 1/2 watt resistors. The best conductive plastic pots only have 10% or 20% tolerance. The ten fold improvement in precision helps a great deal in left-right matching.

    (which may not have been issues for the tube’s original intended use). Manley decided in June of 1996 to begin using a type 5670 dual triode which were similar, importantly sharing the same pin-out as the 6386 and available in sufficient quantities to allow for testing and matching.

    SPECIFICATIONS - MANLEY input & output transformers with nickel laminations in mu-metal cases with flat fre- quency response from 20Hz-25kHz - BALANCED INPUTS & OUTPUTS (600 Ohms) - Fully differential ALL-TUBE circuitry using one each 5670, 5751, 7044 or 5687, & 12AL5 per channel (T-BAR mod replaced 5670’s with 2 pairs of 6BA6’s)

  • Page 15: Technical Notes

    TECHNICAL NOTES TUBE LIFE As with all tubes, their quality degrades with age. This is due to cathode emission, a natural process found in all tubes. We recommend that you have your unit checked every 4-5 years, depending on usage, usually the limiter will require re- tubing after this time has elapsed.
  • Page 16 *NOTE: As of 03/2012, units are shipping with hole plugs covering the ADJUST trimmers to discourage inadvertent un-calibrating of the triode-to-triode balance. ADJUSTMENT PROCEDURE: Turn the unit’s power on, and allow a minimum 45 minute warmup before attempting calibration. If new tubes have been installed, final calibration should be done after a minimum of 8 hours burn-in time in order to stabilize the tubes.

    (just kidding). You MUST complete ONE of the above methods to validate your warranty and registration. Thank you, again, for choosing Manley gear and reading all the way through The Owner’s Manual. (We really mean that sincerely, the bit about thanking you for choosing our gear.
