Standard Audio Level-or Mk2 500 Series Limiter  From Standard

Harmonic distortion, extreme compression, explosive creativity. 

With a core circuit inspired by the Level-Loc PA Limiter from the 1960's, the Level-Or Mk2 500 series compressor/distortion processor captures the gritty vibe and aggressive nature of the original JFET Limiter while providing modern updates and features expected by the modern record maker. In addition to a lower noise floor and dual Level & Crunch operating modes, additional features have been added like true-bypass, adjustable RC timing, and a DI instrument input.

FEATURES

• MODE Switch
• The MODE toggle switch selects between 3 different operating modes.
• LEVEL - Level mode, JFET limiter enabled. High ratio, feedback compression circuit.
• BYP - Bypass mode, true relay bypass enabled. 
• CRUNCH - Crunch mode, harmonic distortion enabled. Multiple discrete, Class-A transistor stages generate harmonic distortion. 
• SPEED Switch 
• The SPEED toggle switch function depends on operating mode.
• LEVEL - Speed switch controls JFET limiter release time: FAST/MED/SLOW.
• CRUNCH - Speed switch controls output Low Pass Filter frequency. Ideal for taming higher order harmonics generated by distorting transistor stages. FAST - filter disabled. MED - 15kHz LPF. SLOW - 8kHz LFP. 
• INPUT Pot
• Controls input level into the JFET Limiter or Harmonic distortion generating transistor stages. 
• MODE Led
• Displays operating mode and indicates amount of gain reduction or distortion. 
• LEVEL - GREEN, brightness indicates amount of gain reduction. 
• BYP - OFF.
• CRUNCH - RED, brightness indicates amount of Harmonic Distortion.
• OUTPUT Pot
• Controls output level.
• 1/4" Input Jack
• Instrument level Direct Inject input (can be configured for line level input with PCB jumpers). 1/4" plug is automatically detected and DI enabled. In BYPASS mode, DI passes clean, unaffected signal to output with gain control via OUTPUT pot. 
• 500 Series Format
• Compatible with the API 500-series format standard - tried and tested in hundreds of racks around the world.
