twinQCS Dual Recording Channel - User's guide
The compressor should now be working and ears can take over the adjustments. The amount of compression in use can be seen from the VU meter; but your ears are always the best judge! THE MONO/STEREO COMPRESSORS. The compressors on the 'TwinQ' are an advanced version of the compressor on the VC1Q. The 5-way slope switch has been improved so that the effective compression ratios are from approximately 2 to 1 on position 1 up to a ratio of 15 to 1 on position 5. This high ratio makes the unit into a limiter. The attack characteristics have also been improved so that at minimum attack time, the compression will be fully effective after less than 0.5 milliseconds. The release system is the same as on the original Joemeek SC2 which has a compound release curve: After a single sudden transient signal, the compression releases extremely quickly. On a normal music signal the compression releases at a speed according to the release control. NOTE. When both attack and release are set to maximum speed (both fully anti-clockwise), the speed of the circuit action is very much quicker than is possible to show on conventional meter movements, so the meters cannot register the amount of transient compression accurately. STEREO OPERATION When the 'link' switch is depressed (yellow light on) and the compressors are both selected 'on', the left-hand compressor becomes the master in all respects: The compression control, the slope, the attack and the release act on both channels. The left-hand meter gives an indication of the amount of compression on both channels. NOTE. When operating in 'stereo' mode, if the right-hand meter is switched to read compression, it will only indicate correctly if the right-hand slope switch is selected to the same slope as the master left-hand switch. It is recommended that when working in stereo mode, the right-hand meter is left switched to reading the audio level at all times.
