LEARNING OUTCOMES • Understand • Identify • Learn 2
SESSION OVERVIEW 4 core components of a sound system How each component functions Advice & tips 2
FOLLOWING ALONG Number at the lower right of the screen corresponds to the page in your booklet. 2
HOW COMPONENTS CREATE SOUND A signal is sent from here INPUT DEVICE MIXER Receives signal & manipulates it AMPLIFIER Magnifies & drives the signal SPEAKER Converts signal to audio waves 3
INPUT DEVICE MIXER AMPLIFIER SPEAKER 4
INPUT DEVICES: MICROPHONES • Not all are the same • Shape • Size • On/off switch • Pick up area • Sound quality • You get what you pay for 4
OTHER INPUT DEVICES • Guitar • Keyboard/Electric Piano • CD Player • DVD Player • Portable Media Player • Laptop Computer 5
GETTING THE SIGNAL TO THE BOARD • XLR • Quarter Inch (6.3 mm) • RCA • Mini (3.5 mm) XLR 6
CABLE ADAPTERS • Mini to RCA • Mini to Quarter Inch • RCA to XLR 6
DIRECT BOX • Adapter for connecting instruments to the mixing board without using a microphone. • Converts signal from high-impedance to low-impedance. i.e. Convert Quarter Inch to XLR 6
SNAKE • “Extension cord” for multiple mic cables • Keeps mic cables organized • Keeps mixer at Front of House (FOH) • Box goes on stage. • Plug XLR cable from mic into the box. • Other end of XLR plugs into mixer. • Also has “returns” to send signal from mixer to stage (stage monitors). 6

DIFFERENT TYPES OF MIXERS • Line Mixer • DJ Mixer • PA Mixer • Standard Mixer • Large Format Mixer Standard Mixer 8
SNAPSHOT OF A CHANNEL • Gain/Trim • High (or Low) Pass Filter • Equalizer • Aux • Pan • PFL Button • Mute Button • Fader 11
SIMILARITIES OF CHANNELS • Gain (a.k.a. Trim) • Equalizer • Aux • Pan/Balance • Fader 12
DIFFERENCES OF CHANNELS • High Pass Filter (or Low Pass Filter) • Mute Button • Pad Button • PFL Button • Channel Indicator Light • Limit Indicator Light • Bus (Subgroup) Selector • Phantom Power by Channel 12
MASTERING THE EQ HIGH HIGH-MID LOW-MID LOW Start at midpoint (12:00) and adjust slowly! LOW MID HIGH 12
PRACTICING WHAT YOU HAVE LEARNED 1. Turn on channel 1. 2. Turn down the volume on channel 2. 3. Put more of channel’s 3 sound in the right speaker. 4. Channel 4 is on. Turn it off. 5. Add more high frequency to channel 5. 6. Give channel 6 more bass. 14

WHAT EXACTLY DOES ANAMPLIFIER DO? BOOSTS SIGNAL & SENDS IT TO SPEAKER 15
2 MOST IMPORTANT FEATURES FOUND ON AN AMPLIFIER • Control knobs • Signal limit indicator light 15
AMPLIFIER SELECTION 2x CONTINUOUS OUTPUT (CONTINUOUS POWER HANDLING. SOMETIMES REFERRED TO AS RMS.) 15
WHY 2x AMPLIFER TO SPEAKER RATIO 1,500 watts Peak Speaker Wattage Output 1,000 watts Amplifier Peak Wattage Output (2x RMS) 500 watts Continuous Speaker Wattage Output (RMS) 0 watts Sound Signal 15
CHALLENGE WITH2x AMPLIFIER POTENTIAL FOR SPEAKER DAMAGE 15
MOST IMPORTANT ADVICEFOR SELECTING AN AMPLIFIER ASK AN EXPERT 15

2 COMMON SPEAKER TYPES • 2 Way Full-Range Speaker • Tweeter • Woofer • Subwoofer (No Tweeter or Mid) 16
WHAT TO EXPECT TO HEARWITH A TWO-WAY FULL RANGE SPEAKER Tweeter Woofer Highs Mids & Lows 16
CONNECTING AMPLIFIER TO SPEAKERS • Quarter Inch • Speak-On 16
OTHER SPEAKERS ON STAGE • Monitor (Wedge) • Guitar Amp • IEM 17
CONTROLLING MONITOR VOLUME AUX KNOBS 17
TWO TYPES OF SPEAKERS PASSIVE VS. POWERED (ACTIVE) ALTHOUGH MORE EXPENSIVE, POWERED SPEAKERS ELIMINATE THE NEED FOR A SEPARATE AMPLIFIER. THE POWERED SPEAKER ALSO MATCHES THE APPROPRIATE AMPLIFIER TO SPEAKER RATIO TO MAXIMIZE SOUND QUALITY. POWERED SPEAKERS CONNECT TO MIXER WITH XLR CABLE, NOT SPEAKER CABLE. 18

CONSOLIDATED EQUIPMENT OPTIONS INPUT DEVICE MIXER Powered Speaker w/ Mixer a.k.a. Self-Contained PA system Powered Mixer AMPLIFIER Powered Speaker SPEAKER 19
THE BEST OPTION FOR NOVICES Powered Speaker Matches the appropriate amplifier with the speaker, AND allows you to have a separate mixing board to match the size of your event. Also eliminates the need to keep an inventory of speaker cables. 19
