 U76 This models a well-known vintage compressor/limiter used in a wide range of situations. Parameter INPUT OUTPUT Range -96.0 to 0.0 dB -96.0 to 0.0 dB ATTACK 5.50 to 0.10 ms RELEASE 1100.0 to 56.4 ms RATIO METER ALL, 4, 8, 12, 20 OFF, +4, +8, GR Description Input level Output level Attack time of the compressor. Turning this all the way to the right produces the fastest attack. Release time of the compressor. Turning this all the way to the right produces the fastest release. Switches the compression ratio. Pressing ALL produces the strongest effect. Switches the meter display  Opt-2A This processor emulates a well-known vintage model of vacuum tube opto compressor. Parameter GAIN PEAK REDUCTION RATIO METER SELECT Range -56.0 dB to 40.0 dB -48.0 dB to 48.0 dB 2.00 to 10.00 OUTPUT+10, GAIN REDUCTION, OUTPUT+4 Description Output level Amount of gain reduction Compression ratio Switches the meter display  EQ-1A This processor emulates a vintage EQ that's considered a classic example of a passive EQ. Parameter Range LOW FREQUENCY 20, 30, 60, 100 Hz (LOW) BOOST 0.0 to 10.0 (LOW) ATTEN 0.0 to 10.0 HIGH FREQUENCY 3k, 4k, 5k, 8k, 10k, 12k, 16k Hz (HIGH) BOOST 0.0 to 10.0 (HIGH) BAND WIDTH 0.0 to 10.0 (HIGH) ATTEN SEL 5k, 10k, 20k Hz (HIGH) ATTEN 0.0 to 10.0 IN OFF, ON Description Frequency range of the low range filter Boost amount of the low range filter Attenuation amount of the low range filter Frequency range of the high range filter Boost amount of the high range filter Band width of the high range filter Frequency range attenuated by the high range filter Attenuation amount of the high range filter Turns the processor on/off. If this is off, the filter section will be bypassed, but the signal will pass through the input/output transformers and the amp circuit.  Dynamic EQ This is a newly developed equalizer that dynamically changes the EQ gain in response to the input signal, controlling the amount of EQ cut or boost in a way similar to a compressor or expander. Parameter BAND ON/OFF SIDECHAIN CUE SIDECHAIN LISTEN FILTER TYPE FREQUENCY Q THRESHOLD RATIO MODE ATTACK/RELEASE Range OFF, ON OFF, ON OFF, ON Low Shelf, Bell, Hi Shelf 20.0 to 20.0k Hz 15.0 to 0.50 -80.0 to 10.0 dB ∞ : 1 to 1 : 1.50 BELOW, ABOVE FAST, SLOW, AUTO Description Turns the corresponding band on/off If this is on, the sidechain signal that controls the dynamics will be sent to the CUE bus for monitoring. If this is on, the sidechain signal that is linked to the dynamics will be output to the bus (such as the STEREO bus or a MIX/ MATRIX bus) to which the inserted channel is being sent. Switches the type of equalizer and sidechain filter Frequency controlled by the equalizer and sidechain filter Q of the equalizer and sidechain filter Threshold value at which processing begins to apply Sets the boost/cut ratio relative to the input signal Specifies whether the processor will operate when the sidechain signal exceeds the threshold setting (ABOVE) or when it falls below the threshold setting (BELOW) Attack time/release time for when compression or boost is applied  Automixer Parameters Parameter Group Override ChMode ChModePreset Range a, b, c OFF/ON man, auto, mute man, auto, mute Weight -200 to 30 MeterType MasterOverride MasterMute gain, input, output OFF/ON OFF/ON Gain 0 to 127 InputLevel 0 to 127 OutputLevel PostWeightingFilter 0 to 127 0 to 127 Description Channel control field group Turns on/off overriding of the channel control field Channel control field mode (man/auto/mute) Preset setting of the channel control field Relative sensitivity among input channels in the channel control field Meter type of the master field Turns on/off overriding of the master field Turns on/off the mute setting of the master field Automixer gain displayed for each channel when the meter button of the master field is set to "gain" Input level displayed for each channel when the meter button of the master field is set to "input" Output level displayed for each channel when the meter button of the master field is set to "output" Level indicator of the channel control field 21 Data List
