IntroductionDiagramsOn the following pages, you will see some connection diagrams. We have set things up to giveyou clear and concise representations of whatgoes where.There are a few things we would like you to keepin mind as you look at the diagrams:1. Inputs to Play Acoustic will be to the left of theback panel image.2. Outputs from Play Acoustic will be to the rightof the back panel image.3. There are two boxes on the bottom of eachdiagram.– The Play Acoustic box shows “what youhear” from your Play Acoustic headphoneoutput.– The P.A. box shows “what you hear” fromthe P.A. speakers.4. We don’t account for other inputs/instrumentswhen showing “what you hear” from the P.A.,so you won’t see pictures of drums etc.5. In a lot of cases, “what you hear” will be thesame for both Play Acoustic headphone output and P.A. – but it can also be different.Play Acoustic – Reference manual (2014-05-09)3PLAY ACOUSTIC5548

BasicsInputs and outputsStereo audio input and output via USB is alsosupported at 16 bit resolution with 44.1 or 48 kHzsample rate.GUITAR DI (R) and VOICE(L) output connectorsConnect the included power supply. Always usea TC-Helicon power supply (12 V, 400 mA).Using any other power supply may damage theunit and will void your warranty.Incoming USB audio signals are not passed tothe USB output, allowing you to sing/play alongwith tracks from your DAW while recording back„just the vocals and guitar“.These are the main output connectors of yourPlay Acoustic. By default, mono vocals are sentvia the Voice (L) connector, and a mono guitarsignal is sent via the Guitar DI (R) jack. This configuration can be changed in the Setup/Outputmenu.USB connectorPhones connectorPEDAL connectorConnect to your computer with the included cable. Use the VoiceSupport software to managepresets and update the product’s internal software (firmware).Connect your headphones to the Phones connector.You can download VoiceSupport here:tc-helicon.com/products/voicesupportThis is a ground lift switch. If you experience humwhile using Play Acoustic, try pressing the GNDswitch to reduce or remove the hum.Use a TRS cable to connect a Switch-3 (optional)to the PEDAL connector. If you use the Switch-3,you have direct access to looping and other effect control. See the Switch-3 menu section fordetails on assigning controls to each Switch-3button.Power socketPlay Acoustic – Reference manual (2014-05-09)GND switch10
BasicsAUX connectorUse a 1/8” cable to connect any music sourceyou want to use to your Play Acoustic (especiallythat 8-Track from your 1974 Comet). When an input is detected here and no guitar is plugged in,Play Acoustic will use the music signal to figureout key and scale information.GUITAR IN connectorIf you see the LED light red – indicating clipping –, it is helpful to play/sing individually to seewhich input may be getting too much level.Keep in mind that the combined level of twoinputs can clip, even when the individual inputs do not. If this happens for you, it’s best tosimply turn down each input slightly until the LEDno longer lights red when you sing and play simultaneously.use the or buttons to move to Page 1. Pressthe “soft” button next to the “Guitar IN” box anduse the Control knob to adjust your level.Reading the LCD DisplayConnect your guitar to this input.MIC connectorWell – this is where the magic happens!Plug your dynamic, condenser, MP-75, or e835fx microphone in here. Remember to set the microphone type and level correctly, as describedin the Play Acoustic Quick Start Guide.How the Input LEDLevel Meter WorksThe LED on the top of your Play Acoustic is usedfor both vocal and guitar level metering.Setting Microphone GainOnce you have connected your microphone andselected the microphone type (Dynamic, Condenser, MP-75, e835 FX), use the Mic Gain knobon the side of your Play Acoustic to set the inputlevel for your microphone.The Play Acoustic displayAs you increase the level, pay close attention tothe LED on top of Play Acoustic. You want theinput to light the LED green. It’s OK if the LEDsometimes lights yellow – but it should neverturn red. If it does turn red, reduce the level. Redmeans that a) the input is overloading and b)you’ve got powerful lungs!Preset NameThe name of the currently selected preset. In thescreen shot above, it is “High Harmony“. ThePresets concept is explained in “What are presets?”.Preset NumberThe unique preset number – i.e., the number ofthe slot where the preset is stored. In the screenshot above, it is 1.When setting the level for your microphoneor guitar, make sure that you sing or playseparately. If you are setting your vocal level,don’t play your guitar – and vice versa.The meter will show a combined level for bothguitar and vocals when you sing and play.Play Acoustic – Reference manual (2014-05-09)The LCD display of your Play Acoustic displaysthe following information:Setting the guitar levelThe control for your guitar input is on Page 1of the Setup menu. You can access the Setupmenu by pressing the SETUP button and then“FAV” indicatorThe “FAV” indicator is shown in the upper rightcorner of the display if the current preset hasbeen tagged as a Favorite.11
Basics“NP” indicatorThe “NP” indicator is shown in the lower rightcorner of the display when chord informationchanges have been detected by Play Acoustic.Genre indicatorIf you have set the Genre selector to any othervalue than “All”, the currently selected genre isshown in the upper left corner of the display. Inthe screen shot above, it is “Harmony“.You may see the “NP” indicator switch on and offsomewhat erratically as it processes incomingmusical information. This is normal.What is NaturalPlay?NaturalPlay is the voodoo we do inside PlayAcoustic to figure out which key your music is in.If you plug your guitar into the GUITAR IN connector, NaturalPlay will look there first for key/scale info. Next, it will look at the Aux input andlisten to the RoomSense microphones.Once Play Acoustic “hears” key/scale information from one of these inputs, it will set the key/scale on the fly. “NP” is only shown when achange in key/scale is detected – so don’t panicif you don’t see it all the time.“LOOP” indicatorThe “LOOP” indicator is shown in the lower rightcorner of the display when a loop is running, butyou are currently not on the Loop mode screen.“GTR BOOST” indicatorThe “GTR BOOST” indicator is shown in the lower left corner of the display when guitar boost isactive.Play Acoustic – Reference manual (2014-05-09)12
BasicsSwitches and operationTALK modeWhen you press and hold the HIT / Hold for TALKfootswitch, Play Acoustic enters TALK mode.In TALK mode, all vocal effects are bypassed,and the microphone input is passed directly tothe output.Up and Down footswitchesForm here on, we will refer – to the footswitch with the down-pointing triangle as the DOWN footswitch and– to the footswitch with the up-pointing triangleas the UP footswitch.The DOWN and UP footswitches allow you tonavigate through presets.HIT / Hold for TALK footswitchTALK/Tuner modeIf you have a guitar plugged into the GUITAR IN,you will enter TALK/Tuner mode, activating theguitar tuner built into Play Acoustic. The guitaroutput is muted to allow tuning, but the dry voiceis still passed to the output, allowing you to tuneyour instrument and still entertain the crowd withwitty banter.During normal operation, this footswitch acts asa HIT button. What does this mean?When you activate HIT by tapping the footswitch,a new effect (or several effects) will be addedto the current sound. This feature is perfect forspicing up a section of a song with a particulareffect, e.g. Harmony.– Press a footswitch once to switch to the previous or next preset slot.– Press and hold a footswitch to quickly movethrough presets.Play Acoustic – Reference manual (2014-05-09)13
BasicsActivating Loop modeTo enter Loop mode, press and hold the DOWNand UP footswitches simultaneously.For more information on the Looper, see “TheLooper”.You may exit Loop mode while a loop is still playing. That means you can choose a new vocalsound – and then re-enter Loop mode to add anew overdub to the loop.Loop Undo/RedoTo undo a loop overdub, press and hold theDOWN footswitch.To restore the overdub (Redo), press and holdthe DOWN footswitch again. Restoring a loopoverdub this way is only possible if you have notrecorded another overdub after using Undo.Looping with a Switch-3The Loop mode screenIn Loop mode, the DOWN footswitch controlsthe following functions:– PLAY– REC (Record)– OverdubHolding the DOWN footswitch will undo yourmost recently recorded Overdub.If you connect a TC-Helicon Switch-3 (optional) to the PEDAL connector of your Play Acoustic,you can use it to control all Loop features.The benefit of using a Switch-3 is the addition ofthe dedicated Undo button.When a Switch-3 is connected, Play Acoustic’sUP and DOWN footswitches are assigned to SetKey/Scale.For more information, see “Switch-3 page”.In Loop mode, the UP footswitch controls thefollowing functions:– STOP– ERA (HOLD to erase)Using DOWN and UP forsetting key and scaleActivating Loop mode by pressing the DOWNand UP footswitches simultaneously is the default mode. There is also an alternative modewhere pressing the DOWN and UP footswitchessimultaneously will allow you to set key/scale.You can set this mode on System page 5 under“UP/DN Function”.When you have activated this alternative mode,pressing the UP and DOWN footswitches simultaneously will allow you to set Key and Scale using these two footswitches.If you don’t know which Key and Scale a particular song is in, try using the last chord of the songfor the Key and Major 2 for the Scale. It’s oftencorrect, especially in popular music.For more information, see “TC-Helicon scalesreference chart”.

Play is learning. Remember that imaginative play or pretend play is thinking play. Pretend play is thinking play because children need to think of what to play, use an object or objects as play props (using the object as a symbol in play is higher level thinking), incorporate a character in the play (like a teddy or doll),
Play types: Play types can be described as the different behaviours we can see when children are playing and there have been numerous attempts to categorise different types of play. Play theorist Bob Hughes describes each play type (social play, rough and tumble play, deep play, role play etc.) as 'both distinctly and
