13、thority: Research and Development Director, Klark Teknik Group (UK) Plc Attention! Where applicable, the attention of the specifier, purchaser, installer or user is drawn to special limitations of use which must be observed when these products are taken into service to maintain compliance with the a

14、bove directives. Details of these special measures and limitations to use are available on request and are available in product manuals. Thank You for using a Midas Verona mixing console. The Verona has been developed to meet the needs of demanding live sound engineers and meets the quality of build

15、 and performance that you would expect from a Midas. The Verona is an all purpose FOH, Monitor or FOH and Monitor Hybrid console that is quickly and easily configurable. Each mono input channel offers microphone and line inputs, direct output and insert points and four band sweep equaliser stage. In

16、 addition the Verona has a flexible buss structure allowing the engineer to mix in stereo or LCR. The Verona, also allows the user to route to any of 20 other busses (8 Auxiliary Busses, 8 Group Busses and 4 Matrix Busses) for even the most demanding application. All backed up, of course, by the sta

20、observed in order to maintain safety and electromagnetic compatibility performance. Power Connection The console should only be operated with the power supply connected to ground via the ground in the mains connector. Audio Connections The console should only be operated with high quality twisted-pa

21、ir audio cables. All connector shells should be of metal construction so that they provide a screen when connected to the console. All jack connector shells should be connected to the cable screen. All XLR plugs should have pin one (1) connected to the cable screen. Electric Fields If the console is

22、 operated in an electromagnetic field that is amplitude modulated by an audio frequency signal, the signal to noise ratio may be degraded. Degradation of up to 60dB may be experienced under extreme conditions (3V/m, 90% modulation). INSTALLATION Position The position of the console will vary from ve

23、nue to venue. However , when positioning the console for front of house usage it is worth placing the console in a position where the sound system used can be heard properly from the mix position. Try to avoid placing the console behind pillars or large objects , or mixing from a level above the spe

24、aker position (e.g. from a balcony). Also try to avoid placing the console near or on any power distribution units or power amplifiers. Power If using an external power supply, it should be located as far away from the console as the connecting cable will allow. The power supply should be set for th

25、e voltage supply available in your area and plugged into the mains outlet using the cable provided. ! THE POWER SUPPLY SHOULD NEVER BE OPERATED WITH THE MAINS EARTH DISCONNECTED Please note that the power supply contains LETHAL VOLTAGES greatly in excess of the mains voltage and that its rails can p

26、roduce extremely large currents which could burn out equipment and wiring if shorted. All testing and servicing should ONLY be carried out by a qualified engineer.

34、f frame, however functionality remains the same Rear Panel 48V Power - When depressed, the Verona will apply 48 volts phantom power to the microphone input. This is used to power condenser microphones, direct inject boxes and other devices that require phantom power. The red phantom LED will light t

35、o indicate that 48V phantom is in operation. -15dB Pad - The Pad switch provides 15dB attenuation to the input signal allowing for the connection of high output microphones and line level signals without overloading the channel input amplifier. Overloads are indicated on the in-channel meter by the

36、red LED at the top. Mic Gain - The mic gain is continuously variable from +15dB to +60dB (0dB to +45dB with the Pad enabled). The actual value of the gain required will depend upon the source and should ideally be set such that peaks in level on the input should not cause the input amplifier to over

37、load (occasional peaks of +12dB is okay, +18dB is too high). Mic - The mic phase switch, when depressed, causes a 180 degree phase change (with respect to the input signal) to occur in the input amplifier such that the channel signal will have opposite polarity to the input signal. The mic phase swi

38、tch is commonly needed where two microphones are used facing each other (for example when using a microphone on both the top and bottom of a snare drum). Ordinarily the two microphones would be out of phase causing cancellation when the console sums the two signals into the output. Reversing the pha

39、se of one signal causes the microphones to have the same phase and no cancellation. Ins - The ins switch enables the channel insert point by connecting the insert return to the channel signal path so that compressors, gates or other dynamic and signal processors or effects can be used. Hi-Pass - The

40、 high pass switch enables high pass filter on the microphone input. This is commonly used to remove handling noise, bass rumble through coupling with the stage or mains hum. High Pass Frequency - The cutoff frequency of the high pass filter is continuously variable from 20Hz to 400Hz. Operators Manu

41、al - Page 8 Channel Equalisation Each mono input channel of the Verona has a four (4) band sweep EQ allowing tonal control over the input signal. Treble (Gain) - The gain of the treble equaliser is continuously variable from -15dB to +15dB with a centre detent at 0dB. Treble (frequency) - The centre

42、 frequency of the treble equaliser is continuously variable from 2kHz to 20kHz. Hi-Mid (Gain) - The gain of the hi-mid equaliser is continuously variable from -15dB to +15dB with a centre detent at 0dB. Hi-Mid (frequency) - The centre frequency of the hi-mid equaliser is continuously variable from 4

43、00Hz to 8kHz. Lo-Mid (frequency) - The centre frequency of the lo-mid equaliser is continuously variable from 100Hz to 2kHz. Lo-Mid (Gain) - The gain of the lo-mid equaliser is continuously variable from -15dB to +15dB with a centre detent at 0dB. Bass (frequency) - The centre frequency of the bass

44、equaliser is continuously variable from 20Hz to 200Hz. Bass (Gain) - The gain of the bass equaliser is continuously variable from -15dB to +15dB with a centre detent at 0dB. EQ On - The Equaliser can be enabled by depressing the EQ On switch. Otherwise changes on the Equaliser controls have no effec

45、t. This can be used to compare the sound with and without EQ during sound check. EQ Off (aux pre) - If desired, the channel signal can be sent to the auxiliary outputs without equalisation. Depressing the EQ Off (Aux Pre) switch causes pre-fader auxiliary sends 1-6 to be sourced before the channel e

46、qualiser (Pre-EQ).
