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 (2014-07-16)3PLAY ACOUSTIC5548

Remember to set the microphone type and level correctly, as describedin the Play Acoustic Quick Start Guide.Play Acoustic – Reference manual (2014-07-16)via 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.AUX 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.GND switchThis is a ground lift switch. If you experience humwhile using Play Acoustic, try pressing the GNDswitch to reduce or remove the hum.GUITAR DI (R) and VOICE(L) output connectorsHeadphones connectorThese are the main output connectors of yourPlay Acoustic. By default, mono vocals are sentConnect your headphones to the Phones connector.10
BasicsPEDAL connectorUse 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.USB connectorConnect to your computer with the included cable.

BasicsGain settingsHow the Input LEDLevel Meter Worksinput 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!The LED on the top of your Play Acoustic is usedfor both vocal and guitar level metering.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.If 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.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 thenuse the or buttons to move to Page 1.

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.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.Preset NameThe name of the currently selected preset.

What does this mean?Form 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.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.The DOWN and UP footswitches allow you tonavigate through presets.TALK modeWhen you press and hold the HIT / Hold for TALKfootswitch, Play Acoustic enters TALK mode.

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-3If 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.where 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”.Tap tempoTo access Tap Tempo, press and hold the UPand HIT footswitches simultaneously.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

AT, an Acoustic Transmissometer Albert J. Williams 3rd Woods Hole Oceanographic Institution MS#12, 98 Water St. Woods Hole, MA 02543 USA Abstract-The combination of attenuation measurement with acoustic travel-time current measurement along a common path has produced a new acoustic sensor of suspended particles, the Acoustic Transmissometer (AT).
As a result of this physical nature of acoustic waves, the composition of the material through which an acoustic wave travels will impact its speed and the energy that is lost due to absorption as the wave propagates through the mate-rial. When a propagating acoustic wave encounters a sudden change in the acoustic impedance (product of sound speed
