Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

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 performance/production

involvement of and interaction with a production team to reflect the collaborative nature of the production process

use of industry-current 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 on-the-job performance by the candidate.

Assessment methods should closely reflect workplace demands and the needs of particular groups (e.g. 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:

industry-current audio mixing consoles

venue in which audio can be mixed for a live event.

Required Skills and Knowledge

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, e.g. theatre, music concert

techniques for adding sub-mixers 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 and/or 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

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.

amplifier

equaliser

loudspeakers

mixing consoles

signal processor (effects units)

Relevant personnel may include:

designer

director
