SERVICE MANUAL

CODE: 270245

Warnings

with the same signal name inscribed.

Address

ATTENTION

Observe

precautions when handling electrostatic sensitive devices.

Notice

Service must be carried out by qualified personnel only. Any tampering carried out by unqualified personnel during the guarantee period

will forfeit the right to guarantee.

For a correct operation of the instrument, after having switched off, be careful to wait at least 3 seconds before switching on again.

To improve the device's specifications, the schematic diagrams may be subject to change without prior notice.

All components marked by this symbol have special safety characteristics, when replacing any of these components use only

manufacturer's specified parts.

The (µ) micro symbol of capacitance value is substituted by U.

The (

Ω

) omega symbol of resistance value is substituted by E.

The electrolytic capacitors are 25Vdc rated voltage unless otherwise specified.

All resistors are 1/8W unless otherwise specified.

All switches shown in the "OFF" position. All DC voltages measured to ground with a voltmeter 20KOhm/V.

Fig.1

Unscrew the 9 fixing screws (A) and move the front panel towards you and lift it up .

Fig.2

To remove the keyboard unscrew the 10 fixing screws (B) underneath it.

Fig.3

To remove the keyboard lift it up some centimeters from the left end only, shift it to the left how it is suf-

ficient to free the right side and extract it entirely. Note: The attraction of the speaker magnetic core can cause
some difficulty.

Fig.4

BE CAREFUL:

disconnect the keyboard cable (C) without forcing it when you remove the keyboard, to

connect the keyboard out of the chassis is needed a longest cable (GM ordering code 840532).

pRP6 TEST PROCEDURE

This procedure are not intended to repair a fault but only to check the proper instrument operations after a repairing
execution. The procedures that follow must be executed in the order specified.

Instrument and Tools

Dual trace oscilloscope (Note: the Oscilloscope must be earth insulated).

Sinusoidal signal generator.

Digital Multimeter.

N.1 Midi cable.

N.1 Stereo jack plug.

N.2 Mono jack plug.

Setup

Insert the mono jacks into the LEFT and RIGHT OUTPUTS.

Check jumper positions: for pRP6 none must be shorted.

Supplies Check

Check with the Multimeter the following voltages on "Cpu & Sound Generator Board":

Switch off
CN7 pin1-4 = +3.6Vdc (+VBAT for memory backup)

Switch on
CN7 pin1-4 = +4.8Vdc (+VBAT for battery recharging)
CN7 pin1-5 = +5Vdc (+5VB for analog DAC supply)
CN8 pin2-4 = +5Vdc (+5V for digital supply)

Memory and System Reset

To Re-set the instrument press the two SOUND/DATA buttons while holding pressed the GRAND PIANO button.
The Led turns off and after some seconds lights on again. This operation clear all data in memory.

Speakers Check

Press and hold C6 note key and then GRAND PIANO and SOUND/DATA UP buttons: playing a note (OBOE preset)
it must be heard from right speaker.

Press and hold D6 note key and then GRAND PIANO and SOUND/DATA UP buttons: playing a note (OBOE preset)
it must be heard from left speaker.

Right & Left Output Levels Check

Check the levels as follow:

Set the VOLUME at max.

Connect the probes of the oscilloscope between the pins of the speakers, set them at 1ms/div. 5V/div.

Press and hold E6 note key then GRAND PIANO and SOUND/DATA UP button: Play the C5 note (OBOE preset) with
the maximum dynamic, the note must be heard from each speaker without distortions or oscillations, the level
displayed on the oscilloscope screen must be 17.5±1Vpp.

Connect the two probe tips of the oscilloscope to the tip and ring contacts of the stereo jack plug plugged into
PHONES and a ground clip to the sleeve of the same jack plug, set it at 1ms/div. 1V/div.

Play the C5 note with the maximum dynamic, the level displayed on the oscilloscope screen must be 4.2±0.1Vpp.

Connect the first trace of the oscilloscope to the tip and sleeve contacts of the mono jack plugged into RIGHT
OUTPUT, set it at 1ms/div. 0.5V/div.

Connect the other trace of the oscilloscope to the tip and sleeve contacts of the stereo jack plugged into LEFT
OUTPUT, set it at 1ms/div. 0.5V/div.

Play the C5 note with the maximum dynamic, the level displayed on the oscilloscope screen must be 1.6±0.2Vpp.

Right & Left Inputs Levels Check

Check the levels as follow:

Set the sinusoidal generator at 1KHz 400mVpp.

Connect the generator to the RIGHT INPUT.

Set the oscilloscope at 2ms/div. 0.2V/div.

A sinusoidal signal of 1±0.1Vpp must be showed on the scope screen.

Also check the LEFT INPUT.

Pedals Check

Plug the switch pedals into the DAMPER JACK socket, press down the pedal and then press a note key: the
instrument plays the note, release the note key and the sound holds on, release the pedal and the sound shuts
off.

Plug the switch pedals into the PEDAL JACK socket, press a note key while pressing the pedal the sound is more
soft.

Midi In/Out Check

Set the Local Off pressing and holding F7 note key and then SOUND/DATA DOWN button.

Playing some notes you do not hear sound, connect the midi cable between MIDI IN and OUT sockets, play again
and now the instrument sound.

Restore the Local On pressing and holding F7 note key and then SOUND/DATA UP button.

Reliability Check

Before reassembling the instrument and before return it to the user, it is a goal verify its reliability:
Leaving it switched on and operating with greatest caution, carefully shake the boards and connections using an
insulated tool to find faulty contacts, bad solderings and so on, at the same time verify the instrument working.
Start the Demo pressing SOUND/DATA DOWN and SOUND/DATA UP simultaneously, leave it switched on for a long
time verifing its functionality occasionnally.
