gentle, so that the compression effect is more subtle and musical. In Hard Knee mode, the curve is more severe, so that signals above the threshold are �squashed� more aggressively. This yields a more audible and pronounced compression effect. The Gain Make-Up control is positioned at the output of the compressor stage, and allows the signal level to be brought back to the same loudness as the uncompressed signal. 4.4 � SOURCE SELECT The Source switch is used to select whether the mic input or line input signal is the source processed by the unit - and the source not selected will automatically be muted. The instrument input will always feed into the main signal path irrespective of whether mic or line is selected, but the Source switch will at the same time select the gain of the instrument input. The Hi setting is suitable for most guitars and basses, while the Lo setting is designed for higher output sources like samplers and keyboards. Some active guitars and basses also have quite high outputs, so if distortion occurs on the Hi setting then switching to Lo will cure this. It is advisable to disconnect any sources from the instrument input when not in use to reduce noise on the main signal path. 4.5 � PHANTOM POWER When selected, the Phantom Power switch applies 48 volts to the microphone input on the rear of the Fat Man 2, enabling condenser microphones to be used with the unit. CAUTION: Never connect or disconnect a microphone whist phantom power (48V) is switched on, as a loud and potentially damaging transient sound may be produced in your loudspeakers. Before connecting a microphone (or switching phantom power on or off), ensure that the master volume control on your amplifier is turned to minimum. 4.6 � 90 Hz HIGH PASS FILTER The 90Hz filter is used to remove unwanted low frequency content from the source signal. Examples of this would be when a vocal is being very closed mic�d and the low frequency content becomes boosted (known as the �proximity effect�) or to remove rumble from foot movement or passing traffic that is being picked up by the microphone. The filter will remove any frequencies below 90Hz, leaving the rest of the signal spectrum unaffected. 4.7 � INPUT GAIN The Input Gain control sets the level of the signal to the input stage of the compressor and is variable between +16dB and +60dB for the mic input, and �20dB and +20dB for the line input. This allows a wide range of signals to be fed into the Fat Man 2, and also allows the tube stages to be driven to a variable
