Xtec EQ1
Inspired by the Pultec EQP-1a, this passive equalizer is a very powerful tool for 
sound enhancement.
GAIN allows compensation for level changes resulting from frequency 
adjustments. Toggle the IN switch to engage or disengage the eect. Select the 
low frequency with the LO FREQ knob, adjust the amount of enhancement with 
the LO BOOST, then adjust the attack with the LO ATT. The same adjustments are 
available for the high frequencies.
Xtec EQ5
This Pultec emulation is a classic analog passive equalizer that oers very 
warmand musical frequency sculpting. Simply select the center frequency for 
the 3bands, then adjust how much low and high you want to boost and how 
much midrange you want to cut.
Wave Designer
Wave Designer is a powerful tool for adjusting signal transients and dynamics, 
such as attack and sustain. Use it to make a snare drum really “crack” in the 
mix or level out volume inconsistencies of slap bass tracks. (Inspired by the 
SPLTransient Designer)
Adjusting the ATTACK knob can add punch or tame overly dynamic signals. 
Increasing the SUSTAIN knob acts in a similar way as a compressor, allowing the 
peaks to carry longer before decay. The eect can also be used to reduce the 
sustain for a more staccato sound. The GAIN knob compensates for level changes 
caused by the eect.
Precision Limiter
Stereo Precision Limiter allows you to set a precise volume limit, 
ensuringdistortion-free, optimal signal integrity. Use the Stereo Precision 
Limiter to boost quiet signals or preventing clipping while preserving the level 
of“hot”signals.
AUTOGAIN activates an additional long-term gain correction, allowing automatic 
gain scaling of varying input level ranges. STEREO LINK applies limiting to both 
channels equally when activated. INPUT GAIN provides up to 18 dB of gain to 
the input signal prior to limiting. OUTPUT GAIN sets the nal gain level of the 
processed signal. SQUEEZE adds compression to the signal to add punch and a 
slight distortion depending on the amount you dial in. ATTACK sets the attack 
time, ranging from 0.05 mS to 1 mS. RELEASE adjusts the release time from 
0.05mS to 1.04 seconds. KNEE adjusts the soft limiting threshold point from 
hardlimiting (0 dB) to maximum soft limiting (10 dB).
Combinator
The Combinator emulates famous broadcasting and mastering compressors, 
utilizing automatic parameter control that produces very eective yet 
“inaudible”results.
The MIX knob allows some of the source signal to pass through unaected. 
ATTACK and RELEASE have dedicated controls, and an Auto Release function can 
be engaged. Global X-OVER, RATIO, THRESH(old) and GAIN controls are available. 
Engage the Spectral Balance Control (SBC) to allow automatic gain balancing 
between the audio bands and its SPEED control to determine how aggressively 
the eect works. The meters can also display band reduction or the SBC gain 
balance, and can display peak outputs. The THRESH(old) and GAIN can be 
adjusted for each band independently.
Fair Compressor
This model of a Fairchild 670 delivers some of the nest colorations in compressor 
history. Two small trim VRs, BIAS and BALANCE, preset the control side chain 
action, a 6-step knob determines the timing, and the 2 large INPUT GAIN 
and THRESHOLD knobs adjust the levels. There are models available for dual, 
stereo-linked, or mid/side operation.
Leisure Compressor
This model of a popular tube-based optical compressor provides natural and 
eortlessly musical compression, inspired by the Teletronix LA-2A. Simply adjust 
the input GAIN and PEAK REDUCTION knob to dial in the amount of desired 
compression, then adjust the OUTPUT GAIN knob for the desired output level. 
The COMP setting will give a gentle compression ratio, whereas the LIMIT setting 
results in a higher ratio.
