    Max Operation Max features two completely independent stereo compressor effects (Comp 1 and Comp 2), and each Comp has its own stereo UA 610 tube preamplifier and EQ. Each Comp can be independently switched to one of the three available compressor effects.

    Important: When Comp 1 OR Comp 2 is on, Max knobs control the sound you hear. When BOTH Comp 1 and Comp 2 are on, knobs control the compressor that is set on the Comp Select switch. Default Settings Max is set to Serial mode by default, where both Comps can be enabled at the same time, and the output of Comp 1 is routed into the input of Comp 2.

  • Page 8 Adjusts reaction time of the compressor after the signal crosses the threshold. Unlike most compressors, you rotate this control clockwise for faster attack (as with the original hardware). Note: For DYNA and OPTA LA-2A compressor effects, the footswitch LED for the selected Comp blinks rapidly when Attack is rotated, indicating the knob has no effect.
  • Page 9 Ratio feature, for limiting beyond the vintage hardware and UAD plug-in versions. From the mind of UA founder Bill Putnam to your pedalboard, Max gives you the same FET compressor used on decades of legendary FET 1176 studio guitar sounds, whether you're looking to make your funk a little funkier, add soulful sustain, or inject subtle infusions of tone.

  • Page 16 Parallel Press the left or right footswitches to toggle Comp 1 and Comp 2 on/off. One or both compressors can be on at the same time. The input signal is split before feeding into each Comp separately, and the outputs of both Comps are mixed before the pedal output.

  • Page 19 You can configure low EQ, high EQ, and 1176 sidechain settings. These settings are dedicated to each Comp. Low EQ The low shelf EQ adjusts frequencies below 100 Hz. You can cut or boost the lows by 6 dB. Set Low EQ to Off for flat bass response. High EQ The high shelf EQ adjusts frequencies above 10 kHz.
  • Page 20 Sidechain Bass Filter The sidechain bass filter removes low-frequency content from the compressor’s control sidechain. This filter reduces FET 1176 compression and “pumping” on bass-heavy audio signals, without reducing the bass content of the audio signal itself. TO ENABLE EQ AND SIDECHAIN SETTINGS Under Compressor 1 or Compressor 2 Settings, tap the EQ setting you want to configure for each preamp.
