  • Page 99: Appendix C Application Notes

    Appendix C: Application Notes This appendix provides application notes as a guide to help you with VeniceF console operation. With its flexible routing and functionality, the VeniceF was designed with real-world sound engineers in mind, working in the real world. So, for engineers that haven’t got a great deal of experience in live sound engineering, the following subsections may provide a few helpful guidelines.

  • Page 100: The Effect Of Eq

    Appendix C: Application Notes channels will receive the same signal at the same time so, typically, when 16 channels are summed together a gain of around 5dB to 8dB will be seen. It is important to leave some headroom in the summing amplifiers so that they do not overload, should the sum exceed the maximum level.

  • Page 101: Unity Gain

    Unity Gain Unity Gain Unity gain is a gain of 1, that is, no gain or attenuation is applied to a signal. If a signal entered a mono line level input of the VeniceF at 0dBu and the gain was set to +10dB (an internal 10dB attenuation sets the net gain to 0dB), then the signal was routed to each output at 0dB, the channel fader was set to 0dB and each output fader was set to 0dB, the output should be 0dBu (or unity).

  • Page 102: Routing

    Appendix C: Application Notes There are a number of solutions to this problem: • Reduce the amplifier’s input attenuators to a level where the amplifier and console clip at the same point. For example, the input sensitivity is 0dBu, setting the input attenuator on the amplifier to -21dB would mean that the console would clip at the same time as the amplifier.

  • Page 103: Mon Mode

    Routing The submix is now set up. The group level can be used to control the overall level of the channels (retaining their relative levels), mute the submix output or solo the submix signal. Note: Muting the submix is not the same as muting the channels. Aux sends and other group sends will remain active.

  • Page 109: Appendix E Best Grounding Practice

    Appendix E: Best Grounding Practice This appendix gives details of the best grounding practices for the VeniceF console in order to get the optimum performance out of it. Safety first The VeniceF is classified as a class 1 device and as such there is a safety requirement for the power cable to provide an earth connection to the console.

  • Page 112: Noise Solutions

    Appendix E: Best Grounding Practice Noise solutions The grounding on the VeniceF is very robust and often such ground loop induced noises are negligible, but to get the very best out of your console, and especially out of any less robust equipment within the overall system, some consideration should be given to good grounding practice as follows: •...

  • Page 114: Balanced Transformers

    Appendix E: Best Grounding Practice Balanced transformers Active electronic circuits achieve good results, but for ultimate noise rejection, transformers are needed. Transformers colour the sound especially at low and high frequencies due to core saturation and impedance rises. They are also expensive, so they are typically only used as external problem solvers when all else fails.

    Ground referenced connections Source Destination Screen Chassis Chassis Screen termination diagram showing screen broken at source Ground referenced connections Many unbalanced signals are passed between pieces of equipment where one of the devices is balanced and the other is not. By careful wiring using two-core cable with an overall screen, it is possible to convert this connection so that it operates in a similar way to a balanced system, with a ground reference that is not corrupted by ground loop currents in the shield.

    Appendix E: Best Grounding Practice connecting balanced external processing equipment to the insert points, the connection method described in this section should be adopted so as to benefit from the CMR of the external unit. For an example of how to wire a ground referenced insert, see Figure 2 on page 14. Unbalanced connections Ground loops with unbalanced signals are more difficult to deal with, but there are several good techniques available.

    XLR shells XLR shells XLR pin 1s should only be used to provide a ground connection for cable screens. The shell (body) of cable XLRs also need to be connected to ground so they provide a screen for the terminals, but they should not be wired internally to the pin 1 terminal. Their ground should be prevented from contact with the panel XLR connector body.

    Appendix F: Service Information Equipment disposal When this equipment has come to the end of it useful life, its disposal may come under the DIRECTIVE 2002/96/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 27 January 2003 on waste electrical and electronic equipment (WEEE). Hazardous substances in WEEE contaminate water, soil and air and ultimately put at risk our environment and health.
