The following facilities are provided as standard: 1 a single pair of VU meters (PPM meters optional). These display the level of the source selected by the METER SELECT switches, and can be calibrated by means of two screwdriver presets on the Master Panel (see earlier in this chapter). The following facilities are only available on the optional meterbridge: 2 4-digit TIMER MODULE. This can be programmed by internal jumpers on the stereo modules to start automatically when the stereo channel is activated, or controlled manually by the local switches. 3 The CUE SPEAKER and associated LEVEL control monitor the output of the CUE bus 2 1 3 Master Module 4. 19 6WHUHR6RXUFH6HOHFW0RGXOH The Stereo Source Select module provides switching from 8 balanced stereo sources, which are presented on a 38-way male EDAC connector to two independent balanced stereo outputs on a 15-way male D-type connector. Switching is done via two independent banks of eight switches.

The onset of severe distortion in the signal path, usually caused by the peak signal voltage being limited by the circuit's power supply voltage. It is the ratio of the extent to which a differential amplifier will cancel noise, which is present on both inputs, compared to its ability to amplify the wanted signal. A ratio of two voltages or signal levels, expressed by the equation dB=20LOG10(V1/V2). Adding the suffix 'u' denotes that the signal is relative to 0. 775V RMS. Adding the suffix 'v' denotes that the signal is relative to 1V RMS. It describes the level of noise which would need to be fed into an ideal amplifier to produce the measured output noise. A device which allows a telephone line to be connected to a broadcast desk in such a way that the caller may hear the programme output without the caller's voice being re-introduced onto the phone line which would cause unwanted feedback.

End User means the person who first puts the equipment into regular operation. Dealer means the person other than Soundcraft (if any) from whom the End User purchased the Equipment, provided such a person is authorised for this purpose by Soundcraft or its accredited Distributor. 2 If within the period of twelve months from the date of delivery of the Equipment to the End User it shall prove defective by reason only of faulty materials and/or workmanship to such an extent that the effectiveness and/or usability thereof is materially affected the Equipment or the defective component should be returned to the Dealer or to Soundcraft and subject to the following conditions the Dealer or Soundcraft will repair or replace the defective components. Any Equipment or component returned will be at the risk of the End User whilst in transit (both to and from the Dealer or Soundcraft) and postage must be prepaid. This warranty shall only be available if: a) the Equipment has been properly installed in accordance with instructions contained in Soundcraft's manual; and b) the End User has notified Soundcraft or the Dealer within 14 days of the defect appearing; and c) no persons other than authorised representatives of Soundcraft or the Dealer have effected any replacement of parts maintenance adjustments or repairs to the Equipment; and d) the End User has used the Equipment only for such purposes as Soundcraft recommends, with only such operating supplies as meet Soundcraft's specifications and otherwise in all respects in accordance Soundcraft's recommendations. 5 Defects arising as a result of the following are not covered by this Warranty: faulty or negligent handling, chemical or electro-chemical or electrical influences, accidental damage, Acts of God, neglect, deficiency in electrical power, air-conditioning or humidity control. [. . . ] The +48V regulator is a TL783C high voltage device housed in a TO220 package. It can be removed by first withdrawing the PCB, desoldering the three legs and unscrewing the M3 fixing screw, taking care to retain the small insulating bush beneath the head of the screw. Again, an insulating SIL pad is used and this should be replaced if it appears to be damaged. The metal tab at the top of the package is at the output potential of the device, as is the centre lead.
