User manual SCORPA SY 250

[. . . ] 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. The defective unit is to be returned carriage prepaid to SCORPA or its authorised agent with proof of purchase. Check with your SCORPA agent for any additional warranty which may apply. This product complies with the European Electromagnetic Compatibility directives 89/336/EEC & 92/31/EEC and the European Low Voltage Directives 73/23/EEC & 93/68/EEC. This product has been tested to EN55103 Parts 1 & 2 1996 for use in Environments E1, E2, E3, and E4 to demonstrate compliance with the protection requirements in the European EMC directive 89/336/EEC. [. . . ] Fully anticlockwise all the signal routes to L and none to R, and fully clockwise the reverse is true. This ensures equal power as the sound is panned from one side through the centre to the other side. It also has a mechanical detent to help you find its default centre position quickly. PK! The PFL switch LED also provides a channel signal peak indication. The indicator lights brightly when the pre-fade signal reaches +16dBu. This means that it lights 5dB before clipping to give you the chance to reduce the signal before you hear any distortion. Indicator flashes turn back the channel gain control until it stops. Using PAN If you are working with a stereo PA system use PAN to set the position of each signal in the mix. In live sound mixing it is best to set pan centre or close to centre for most signals so that all listeners hear a similar balance regardless of their position in the room. Sounds such as kick drum, bass and lead vocal would usually be set centre. Ambient or backing sources may be panned slightly to spread the image. Stereo sources such as backing tracks, keyboards and sound effects may be panned fully or use the stereo channels instead. If you are working with a mono PA system simply set all pan controls centre. FADER A 100mm smooth travel fader adjusts the signal level feeding the main LR mix, AUX and FX sends. 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 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. In its up position it is flush with the panel and mixes the ST1(3) signal with ST2(4) to feed the stereo channel. [. . . ] Plug into the SPDIF coax input on equipment such as recorders, digital audio processors and computer sound cards. Bypassing the input ADC devices on such equipment can reduce audio quality degradation, especially if they use low grade devices. Connecting SPDIF Use 75 ohm coaxial cable. Do not use standard RCA to RCA audio cables. Do not plug SPDIF signals into analogue connections. While it is unlikely to cause physical damage it can result in unpleasant audible noise. AB SLAVE OUT TRS line outputs for connecting to external line level equipment such as booster amplifiers. [. . . ]
