10、radiation e.g. high power cabling, video monitors and radio transmitters may cause degradation of the audio quality due to induced voltages in the chassis and connection leads. Site the console away from such sources. For the same reason it is advisable to site the power supply away from the console

11、. Electronic components are susceptible to conditions of excessive heat or extreme cold so take care not to use your console under such conditions. Before powering up the console make sure that the power supply voltage selection matches the local mains supply. Never connect or disconnect the power c

12、able without switching off the power supply. Similarly switch off the console before removing or servicing modules. Do not attempt to wipe clean the console with a cleaning liquid. Most surfaces can be simply cleaned with a soft dry brush. Should the chassis or channel ident strips need cleaning use

13、 only water or isopropyl alcohol. Solvent based products should not be used as they may damage these parts. Use a wax based crayon to write on the scribble strips. The use of adhesive backed tapes may damage the screen printing on the modules. TRANSPORT It is recommend that you retain all the packin

14、g from your console should you ever need to return it for service or move the console to other premises. If the console has to be moved regularly then we suggest that you purchase a foam lined flight case, available from your distributor if you cannot purchase one locally. Only use the power supply

15、and cables provide. Your warranty is invalidated if other supplies or cables are used. If you experience any problem with the local mains, or during thunder storms, switch off the power supply and unplug it from the mains supply. SAFETY PRECAUTIONS 6CS12M OPERATION MANUAL CS12M QUICKSTART For this y

16、ou should have the following items available. nMicrophone and cable. nPower amplifier with mains cord and signal cable. nLoudspeaker with connecting cable. nHeadphones. nCS12M console with power supply. First of all make sure that the power supply is suitable for connection to your local supply and

17、then connect the console to the power supply. Connect your loudspeaker(s) to the amplifier and set the volume control(s) to a low level. Connect the microphone into channel 1 and the power amplifier into Monitor Send 1 Output. Switch ON the console BEFORE switching on the power amplifier. Check that

18、 the leds on the master module illuminate for the +/- 18V and +48V power rails. If phantom power is required for your microphone then ensure that the +48V ON led is illuminated. If not use a blunt non conducting instrument such as a pencil or pen to push the switch which is located under the panel.

19、Press the +48V switch on the input module if phantom power is required, for a condenser mic or DI box. INPUT GAIN Select hi gain on channel 1 by having the GAIN switch in the UP position. Turn up the INPUT GAIN control on channel 1 until the signal present led is on but not so high that the peak led

21、ch is neither pressed or illuminated. Turn the control for monitor send 1 to around number 7. Push up the fader on output module 1 to the 0dB point. Look for signal on the group output meter by speaking into the microphone. The level should be around +6dB with occassional flashing of the red leds. T

22、he BUS PEAK leds should not flash. If the level is too low then re-adjust the input gain control on the input module. Ideally the input fader should remain close to the 0dB point with the SIGNAL PRESENT led ON. The PEAK led should not be indicating other than very occassionally. If the input level i

23、s too high then reduce the gain with the INPUT GAIN control. If the power amplifier and loudspeaker are connected to this output you will then hear yourself from the loudspeaker (beware of feedback). 12 1212 CS12M QUICKSTART 8CS12M OPERATION MANUAL Do not attempt to plug microphones into these conne

It will show the pre fader signal from the input module. This can only be changed by adjustment of the INPUT GAIN control. Cancel th

The 48V ON switch

39、on the master module must be ON for phantom power to operate. Optional balancing transformers may be fitted to the Mic/Line Inputs. GAIN RANGE The gain control is a wide range rotary potentiometer which is active on both Mic and Line Inputs. With Mic selected the gain can be adjusted from 15dB to 65

40、dB. For Line inputs, the adjustment is from -10dB to +20dB. HI/LO GAIN Pressing this inserts an attenuator into the input circuit and alters the range of gain adjustment available. This should be pressed when high level or line level signals are connected to the channel through the line input jack.

41、Note that if a jack is not inserted into the line input socket then the XLR connector may be used as the line input. The TRS jack could also be used as a microphone input although this is not recommended and phantom power will not be available. ? REV Pressing this reverses the phase (or more correct

42、ly the polarity) of the left input signal. If a sound source is picked up by more than one microphone and there is a phase or polarity difference between the microphones then the signal may be completely or partially cancelled leading to a very thin sound. Phase or polarity reversal can be used to c

43、orrect the situation. In some instances the cancellation induced by using polarity reversal can be used constructively to eliminate spill from one microphone to another although care is required when trying this. On the stereo input the ? reverse switch can be used to compensate for opposing microph
