User manual SCORPA LONG RIDE

[. . . ] The equipment has not been subject to misuse either intended or accidental, neglect, or alteration other than as described in the User Guide or Service Manual, or approved by SCORPA. Any necessary adjustment, alteration or repair has been carried out by SCORPA or its authorised agent. This warranty does not cover fader wear and tear. The defective unit is to be returned carriage prepaid to SCORPA or its authorised agent with proof of purchase. [. . . ] Normal operating position for dominant sounds is around the `0' mark, with the quieter backing sounds typically in the range `0' to `20'. The +10dB boost is there to give you a bit extra when you need it. If you find your normal setting is near maximum fader position or well below `0' then use PFL to check that the gain is correctly set. Press this switch to turn the channel signal off. The large red LED lights to warn that the channel is muted. Mute affects the channel pre and post-fade sends. This ensures that the feeds to the foldback monitors, effects, aux and house mix are turned off when the channel is muted. You can still use PFL to check the signal while the channel is muted. To avoid loud clicks or unexpected noises always mute the channel before plugging or unplugging microphones and other sources. MUTE The fader scale is graduated in dB (decibel) markings. It relates the fader output level to its input level. If the output is the same as the input then the gain is 0dB. That is why the fader is marked `0' at its normal operating position, the point at which all the channel signal is fed to the mix. For convenience, one uses RCA phono connectors, the other uses TRS jacks. The two inputs mix together to feed the channel strip, or ST1(3) can be routed direct to the LR mix instead, leaving ST2(4) to feed the channel. This provides a very flexible arrangement for mixing up to four stereo sources. ST1(3) INPUT RCA phono inputs for connecting line level stereo signals. These connectors are popular with consumer and semi-professional equipment such as tape deck, video camera, computer, CD and MiniDisc players. ST2(4) INPUT TRS jack inputs for connecting line level stereo signals. The inputs are unbalanced but can also accept balanced sources. The ring connection grounds the ­ve (cold) signal to unbalance a connected balanced source. Typical applications include stereo keyboards, voice modules, effects processors and sub mixers. -10 -20 -30 O O 0 5 10 Using the stereo channels These inputs are intended for local stereo sources. The unbalanced connections work fine with the higher voltage levels and low impedance associated with such equipment. If you need to connect equipment further than 10 metres away we recommend you use the mono channel balanced line inputs or DI boxes feeding the long cables to the mic inputs. This small switch is recessed to prevent accidental operation once it is set. [. . . ] Because of the input stage inversion it therefore cancels and is rejected leaving a clean audio signal. The balanced outputs can work with unbalanced equipment inputs by linking the XLR pin 3 (-) to pin 1 (ground). 30 PA User Guide Fitting the PA12 Rack Ears A pair of 19" rack ears is provided with the PA12. The ears replace the front and side trims so that the console can be mounted in a rack, plinth or case. Note that the PA12 can fit into a standard 19" rack. [. . . ]
