Classic JFET Limiter and Class-A Harmonic Distortion in a 2-Channel 19" Rack

The next evolution of the classic JFET limiter circuit known for its aggressive compression and harmonic distortion, the Level-Or Mk2 DUAL rack unit builds on the features of its 500-series counterpart. 

Added features include a stereo linked compressor sidechain, MIX control for blending wet/dry signals, and a unique CASCADE mode that expands the sonic palette. 

These new features and more are packaged into a rugged steel and aluminum 19" rack chassis with low-noise internal power supply.

DUAL Channel Operation

• S/C LINK mode links both channel's sidechains for stereo operation (in LEVEL mode). 
• IND mode configures both channels to operate independently.
• CASCADE mode routes the output of CH 1 to the input of CH 2. This allows for both channels to operate serially on a single mono source. 

MIX Control

• The MIX pot controls how much of the processed (wet) signal is blended with the original (dry).

Internal Power Supply

• A custom power supply provides a stable and quiet voltage source for the Level-Or circuit. Power is connected via a standard IEC cable. The power supply accepts universal input from 85-240VAC.   

FEATURES

• 1/4" Input Jack
• Instrument level Direct Inject input. 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. 
• INPUT Pot
• Controls input level into the JFET Limiter or Harmonic distortion generating transistor stages. 
• MIX Pot
• Controls blend of processed and dry signal allowing for parallel compression/distortion. Rotate fully clockwise for 100% processed signal. 
• OUTPUT Pot
• Controls output level.
• 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. 
• MODE Led
• Displays operating mode. 
• LEVEL - GREEN.
• BYP - OFF.
• CRUNCH - RED.
• GR/THD Leds (x3)
• Indicate amount of gain reduction or harmonic distortion, depending on MODE. 
• LINK Switch 
• The LINK toggle switch selects between 3 different modes.
• S/C LINK - With both channels in LEVEL mode, the side chains are linked to reduce stereo image shift during gain reduction.
• IND - Both channels fully independent. 
• CASCADE - The output of CH 1 is internally routed to the input of CH 2 allowing both channels of processing to be used on a mono signal path. 
• Universal Input, Linear Power Supply
• Industry standard IEC power connector, will operate from wide range of input voltages at 50-60Hz. 
• INPUT & OUTPUT XLR Connectors
• Line-level audio inputs and outputs on rear panel, gold plated pins. 
• GROUND LIFT Switch
• Toggle switch lifts the chassis ground connection (XLR PIN 1) on the input connectors, simplifying the elimination of ground loops.
