Aurora Audio GTC2 - Manual (Page 6)

NB. For the stereo link to function properly, both channels should have the same
control element selected (i.e opto/FET/combined) and the bypass and sidechains
should both be switched to the “on” position.
This can be easily ascertained by comparing the lighted buttons on one channel with the
other.
5. Specifications
Input Impedance = 10Kohm balanced and floating, transformer coupled.
Output Impedance = <75ohm balanced and floating, transformer coupled
Output drive capability = +26dBu into any load of 600 ohms and above
Frequency response = 20Hz to 20KHz ± 1dB
Total Harmonic Distortion = < 0.1% @ +20dBu O/P @ 1KHz
Noise = < -75dB filtered 20Hz to 20KHz
Side chain voltage = Typically between 0v minimum and +10v maximum
(Greater d.c. voltages provide greater compression.)
6. Tips for users :-
Ah, what to expect here?!!! I'm only the designer and feel sure sure that, with minimal
practice, you will be able to email me with tips on good settings for particular
instruments or vocals! I look on the unit as a tool with which I have provided more than
adequate variations for you to sculpt the sound you desire!
As a very general guide/starting point, I suggest the following :-
Threshold = minimum (fully counter clockwise)
Ratio = minimum (fully counter clockwise)
Attack = maximum (fully clockwise)
Release = minimum (fully counter clockwise)
Gain = 0dB (fully counter clockwise)
