    The term User Song is used  to refer to songs recorded 
    using the instrument itself; Import Songs are those 
    created on another device. User Songs are kept in a 
    folder named USER FILES on a USB flash drive; 
    Import Songs are stored outside this folder. For this 
    reason, User Songs will be handled as Import Songs if 
    the name of the folder is  changed or they are moved 
    outside the folder using a computer. 
    When organizing files on a USB flash drive using a 
    computer or the like, be su re to place Import Songs 
    only in the first, second, or third hierarchical folder 
    level. Your digital piano will  not be able to select or 
    play songs from a lower level.  Checking the write protected status
    Before you use a USB flash drive, you should ensure 
    that it is not write protected. Your digital piano will 
    not be able to access data on a write-protected USB 
    flash drive.

    Performing Li ve
    Your digital piano features a number of convenient functions for use when setting it up on stage in order to per-
    form live. In order to provide a practical description of th e connections and settings required in this type of situa-
    tion, we will focus on the followi ng two typical modes of use. 
    • Performing on-stage as part of a band
    • Singing and playing on your own
    The following description covers performances 
    together with other musicians on-stage at a live music 
    club, performing arts venue, or the like. 
    Stage setup and signal flow
    The sound from your digital piano will be sent to a PA 
    mixer in order that its volume can be balanced with 
    that of the other instruments. From there, the mixed 
    sound is amplified and sent to the front-of-house 
    speakers so that the audience can hear it. Monitor 
    speakers will be placed on the floor in front of the 
    musicians so that they can  more clearly hear their own 
    sound and that of the other instruments.  
    Connect your foot switch or pedal. 
    When plugged into the [SUSTAIN PEDAL] jack, the 
    bundled foot switch can be used to turn on and off sus-
    tain. (See page 11.)
    
    Connect the instrument’s output to the PA mixer. 
    In order to be heard, your instrument will need to be con-
    nected to the PA mixer’s inputs. Normally, this connec-
    tion is made via a DI box (direct box) located on-stage. 
    As described in the note on the left, you should ensure 
    that your digital piano is turned off and check with the 
    PA operator before connecting to a DI box. When you get 
    his or her OK, connect the [L/L+R] and [R] AUX OUT 
    jacks on the instrument’s rear panel to the DI box inputs 
    using standard mono audio cables (sold separately). 
    If DI boxes are not being used, connect the [L/L+R] and 
    [R] AUX OUT jacks on the instrument’s rear panel to the 
    Performing on-stage as part of a band
    Please read the following before setting up. 
    • Ensure that the instrument is turned off before making any 
    connections. In addition, you should always check with the 
    PA operator and wait for his or her OK before connecting or 
    disconnecting cables. Connection or disconnection when 
    the operator is not ready can damage the PA system. 
    • Do not turn on your digital piano as soon as you have made  all of the required connections. You should always set the 
    [MASTER VOLUME] slider to the MIN position and get the 
    OK of the PA operator before turning on or off the instru-
    ment. Turning your digital piano on or off when the operator 
    is not ready can damage the PA system.

    Sound setup
    Once all of the instruments an d microphones have been con-
    nected, the PA operator will as k each musician in turn to 
    play his or her instrument. Yo u should get ready as follows. 
    Turn on your digital piano. 
    As described in the note on  the previous page, first set 
    the [MASTER VOLUME] slider to the MIN position 
    and then check with the PA  operator whether you can 
    turn on the instrument. Wh en you get the OK, press 
    the [ ] Standby/On switch to turn it on. 
     Check your settings. 
    Once turned on, ensure that yo ur digital piano is set up

    need to  use these speakers if yo u can hear yo ur own so und 
    from an on-stage monitor speaker. (See page 44.)
     Determine the best digital-piano volumes. 
    When asked by the PA oper ator to output a sound, 
    play the digital piano as you would when performing 
    and determine the best se ttings for the following. 
    ume when yo u are playing accompaniment
     ume when yo u are playing lou dest, such as d uring a key-
    b oard solo
     ume of each Voice to  be  used
    Roughly speaking, the [MASTER VOLUME] slider 
    should be set between 5 and 7 for playing accompani-
    ment and to 8 or 9 when you need to play louder. If set 
    too high, your sound may become distorted; if too 
    low, any background noise will be more noticeable. 
    When the volume needs to be  finely adjusted for dif-
    ferent Voices or raised in order to play a solo, you 
    should do this yourself  using the [MASTER VOL-
    UME] slider. Similarly, you should use the [EQ] slid-
    ers to keep the tone well balanced. 
     Balance the overall sound of the band. 
    After the volumes of the various instruments have 
    been set, the PA operator will have everyone play 
    together in order to balan ce the overall sound of the 
    band. At this time, you sh ould listen to the nearest 
    monitor speaker and ensure  that you can hear every-
    thing you need to in order to play well. If, for exam-
    ple, you cannot hear your own sound, the singer, or 
    another instrument well enough, ask the PA operator 
    to raise the corresponding le vel in your monitor’s mix. 
     Lock the control panel to prevent mistakes. 
    Your digital piano’s Panel Lock function allows you to 
    temporarily disable control-panel buttons to prevent 
    them being operated unintentionally while perform-
    ing. To activate this function, press the [EFFECT] and 
    [SOUND BOOST] buttons together. 
    Note that the following will continue to operate nor-
    mally when the control panel is locked.

    • If only one of the mixer’s channels is available for use with your digital piano, 
    connect the [L/L+R] AUX OUT jack to the corresponding input jack using a stan-
    dard mono audio cable. In this configurati on, your left and right signals will be 
    mixed and output from the instrument in mono.

    P-255 Owner’s Man ual39
     We recommend setting the [EQ] sliders to their central posi-
    tions and adj usting the o verall tone u sing the key board ampli-
    fier. This approach pro vides the maxim um adj usta ble range 
    sho uld yo u need to change the tone d uring yo ur performance. 
    
    We recommend that yo u turn the So und Boost f unction on. 
    This f unction  boosts the presence of your instr ument so that 
    the entire a udience can clearly hear not only notes played  very 
    lo ud,  but also those played soft. 
    You can choose from three dif-
    ferent types of sou nd boost. (See page 18.)
     Check your settings. 
    Once turned on, ensure that yo ur digital piano is set up 
    as follows.

    (page 44)
     Lock the control panel to prevent mistakes. 
    Your digital piano’s Panel Lock function allows you to 
    temporarily disable control-panel buttons to prevent 
    them being operated unin tentionally while perform-
    ing. To activate this function, press the [EFFECT] and 
    [SOUND BOOST] buttons together. Note that the fol-
    lowing will continue to op erate normally when the 
    control panel is locked.

    Performing
    When playing live, relax and try to listen to the overall 
    sound of your performance so that you can make 
    small adjustments if necessary. For example, you 
    could use the [MASTER VOLUME] slider to keep the 
    vocal and digital-piano volumes well balanced. 
    This completes the set up process. Yo u sho uld 
    now  be ready to play li ve.
