  • Page 2 10358 Las Lunitas Avenue Tujunga, CA 91042 EMAIL: Info@auroraaudio.net Telephone: 323 428 9532 Web Site: http://www.auroraaudio.net Aurora Audio GTC2 V10 Dual Compressor Owner's Manual Table of contents :- 1. Introduction 2. Rear panel connections, audio and power connections 3. Front panel controls 4.
  • Page 3 1 = ground. In the center of the panel is a 1/4” T.R.S. Jack socket. This is the side chain linking connector to enable the GTC2 to link to other GTC2 compressors and link their side chains together for multi-channel compression.
  • Page 4 3. Front Panel Controls The drawing above shows the right hand channel, the left channel is similar. The six control potentiometers function as follows :- NB There is one further small detent at either end of the pot rotation. Threshold (Grey knob) :- A 17 detented potentiometer with a total range of 40dB, i.e from -10dBu to +30dBu.
  • Page 5 The seven illuminated switches are as follows :- NB. The first item is with the switch off, the second with the switch on. Bypass/In (Green switch) :- With the switch deselected, there is a hard (relay switched) connection between the input and output XLRs. This also applies when the unit is switched off/powered down and means that it could be left in a circuit path without disturbing continuity.
  • Page 6 When the Auto button is pressed the release time is dependent on the nature of the program material passing through the compressor. Generally the release times are longer but, if the material is short bursts of sound, the auto timing capacitor will have less stored energy and will produce shorter release times.
  • Page 7 Also the control of the stereo image is achieved pre the pan and gain potentiometers so it is essential that these also are in the same setting for both left and right channels. As they are both non-detented, it is easy to move them to the precise point where stereo balance is restored.
  • Page 8 0VU region (with the meter set to output level). The balance control allows for parallel compression by panning between non- compressed signals and fully compressed signals within the unit. If the GTC2 is compressing heavily the output level may be less than the input level and some gain increase will occur as the control is moved towards non-compressed.
