Piano-3

POWER
After safely connecting the supplied power supply firstly to the piano and then the mains, turn on the piano by pressing the POWER switch. The display will light up.
AUTO POWER OFF
The unit will Auto Power Off after 30 minutes of no operation, except when playing demo songs.
SETTING THE VOLUME
It is advised to set the [MASTER VOLUME] to “MIN” when powering on the piano, and then adjust the volume to your desired level when playing.

CONNECTIONS

USING HEADPHONES
The SDP-3 has a 1/4” output jack (PHONES) for connecting standard stereo headphones. The output volume level is controlled using the main master volume wheel. The internal speaker system is automatically muted when a pair of headphones is plugged into the PHONES jack.

**USING AN EXTERNAL SOUND SYSTEM

Gear4music-SDP-3-Digital-Stage-
Piano-5 **

The LINE OUT (R) and (L)(MONO) phono sockets can be used to connect the piano to an external sound system, such as a keyboard amplifier, inter-face, or mixer. When using one cable (for mono output), insert your cable into the (L)(MONO) out-put. Connecting two cables sends separate left and right audio signals down each cable, giving you stereo output.
AUX INPUT
The Aux Input 3.5mm jack allows you to mix an external sound source (such as a smartphone or MP3 player) with the piano’s internal sounds, for playback through the piano’s in-built speakers or headphone output. The volume of the Aux Input is controlled by the external sound source.

MIDI OUTPUT
Use this output to transfer MIDI data, including note and touch velocity, via a 5-pin MIDI cable (not included).
USING USB MIDI
The SDP-3 allows the transfer of MIDI via USB from the piano to an audio interface or “host.” Use the audio interface to control the MIDI signal.
SUSTAIN PEDAL
The foot pedal included with your digital piano can be connected to the SUSTAIN input and, when held down, allows the sound of the notes played to decay slowly, or “sustain.” A piano-style foot pedal may also be used. The sustain input will auto-detect the polarity of the sustain pedal used. Ensure the piano is turned off before connecting the pedal, otherwise it may not be recognised by the piano correctly. To change the polarity of the pedal, hold the foot pedal down during power up.

USING DC POWER INPUT
The power input is used to connect the piano to mains power. Only use the included power supply unit (PSU).

USING BATTERY POWER
Ensure all batteries are inserted correctly, as indi-cated by the +/- polarity markings. Replace all the batteries at the same time. Do not combine old and new batteries and do not mix battery types, as this can cause overheating, fire, or battery fluid leakage. Remove the batteries from the instrument if it is not to be used for a long period of time.

DEMO SONGS

The SDP-3 features 16 demo songs, each demonstrating a different voice.To select a demo song, press the [METRONOME] and [TEMPO] buttons simultaneously. The first demo song will feature the Piano 1 voice. The metronome and tempo buttons will flash. During playback, another demo song may be chosen by pressing a different voice select button. Alternatively, use the data control wheel to select different demo songs.To stop the demo song. Press the [METRONOME] and [TEMPO] buttons together again. To replay the current song from the beginning, press the flashing voice select button.

SELECTING A VOICE

The piano has 16 different built-in voices. These digitally sampled musical instrument sounds may be selected one at a time or layered to produce two voices at once. To select a main voice, press the appropriate voice select button on the right side of the front panel. This will select the voice name above the button. Pressing the [BANK] button allows you to then select the second set of voice names below the voice buttons. The data control wheel can also be used to select the different voices

LAYER MODE

To add a second voice on the left-hand section of the piano to the voice currently selected, press the [SPLIT] button and use the data control wheel to select the desired left-hand voice. The point at which the piano is split can also be adjusted by holding down the [SPLIT] button for 2 seconds and then playing the desired split point key. Please refer to the Function Menu for how to adjust the volume, octave, and pan settings of the split voices. To exit the split mode, press the [SPLIT] button again.
