Elements and Performance Criteria

1. Tune and balance audio equipment
   • Power up equipment and check to ensure it is in working order
   • Match interfaces between audio and destination in accordance with level, impedance, phase and frequency
   • Route signals to correct signal path
   • Operate faders to produce an audio level in accordance with production requirements
   • Operate audio controls in accordance with acoustic and dynamic requirements
   • Promptly identify faults and problems and take appropriate action to rectify or report to relevant personnel
   • Complete audio check, implement any required adjustments and document accurately in accordance with organisational requirements
2. Mix audio sources
   • Mix audio to produce the required audio level and tonal balance in accordance with production requirements
   • Monitor signal paths throughout the performance
   • Select effects in accordance with production requirements
   • Adjust equalisation for required tonal balance
   • Adjust relative fader levels in accordance with the musical context
   • Balance signal levels appropriately
   • Produce transitions between sound signals that are technically accurate and produce the required effect
   • Ensure that the level of the composite signal is within technical limits and the desired dynamic range
   • Maintain overall audio level in accordance with venue requirements and safe noise levels

Required Skills

Required skills

communicating skills sufficient to liaise with other stage technicians planning and organising skills tomanage and monitor the mix during performance numeracy skills sufficient to set gain structure problems solving skills in the context of identifying and responding to need for adjustments to mix during performance technology skills tooperate a mixing console

Required knowledge

console types and features both small and large FOH consoles analogue and digital and their mixing capabilities matrix and main outputs of consoles and their use typical mixing requirements for different types of performance eg theatre music concert techniques for adding submixers and properly patching into system overview of VCA masters and use of them overview of working with automation and working with snapshot automation and cue delivery overview of the use SMPTE andor MIDI to fire cues and automation dynamic automation factors sufficient to understand processing limitations and interface required for timed dynamic automation and crossfades overview of contemporary audio effectors and DSP effects overview of signal processing options and their applications including use of signal processing as a tool for troubleshooting and creative uses for effects and signal processing

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	The following evidence is critical to the judgement of competence in this unit ability to use the range of console features to mix audio which meets the requirements of a production knowledge of specific techniques for mixing audio in different environments
Context of and specific resources for assessment	The assessment context must provide for practical demonstration of skills through the mixing of audio for more that one live performanceproduction involvement of and interaction with a production team to reflect the collaborative nature of the production process use of industrycurrent equipment
Method of assessment	Assessment may incorporate a range of methods to assess performance and the application of essential underpinning knowledge and might include evaluation of the mix at a live event where the candidate is responsible for mixing audio case studies to assess ability to adapt mix to different production environments oral or written questioning to assess knowledge of mixing techniques and equipment features review of portfolios of evidence and third party workplace reports of onthejob performance by the candidate Assessment methods should closely reflect workplace demands and the needs of particular groups eg people with disabilities and people who may have literacy or numeracy difficulties such as speakers of languages other than English remote communities and those with interrupted schooling
Guidance information for assessment	Assessment of this unit requires access to industrycurrent audio mixing consoles venue in which audio can be mixed for a live event

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Equipment operated to mix audio must include:	a range of microphones amplifier equaliser loudspeakers mixing consoles signal processor (effects units)
Relevant personnel may include:	designer director performers stage manager other technical staff
Effects may include:	compression distortion echo gates limiters pitch band reverberation
