Please make sure that the line voltage in your area meets the requirements. • Do not use the PK-5A on the same power circuit with any device that will generate line noise (such as an electric motor or variable lighting system). • It is normal for this unit to become hot while being operated. • If the unit is not to be used for a long period of time, unplug the external AC adaptor from the outlet. • Disconnect the AC adaptor immediately in the event of an electrical storm. • Before setting up the PK-5A with other MIDI devices, switch it off along with all other units. • Be sure to connect the MIDI cables securely. If the MIDI cable is disconnected while the instrument is being played, various problems may occur (e.g. a note may continue to sound). • Static electricity may cause the built-in computer to malfunction. Should this occur, simply reset the PK-5A by turning the power off and then, after a few seconds, back on. • The PK-5A might not operate correctly if turned on immediately after being turned off. If this happens, simply turn it off and after a few seconds later, turn it on again. • Operating the PK-5A near a neon light, fluorescent lamp, TV or CRT display may cause noise interference. If so, change the position of the instrument. • To avoid risk of electric shock, do not perform any servicing. Refer all servicing to qualified service personnel. r 4 [4][4] 3. The care of your PK-5A To ensure the best use and full enjoyment of your PK-5A, please read this guide carefully and thoroughly. Location Avoid using the PK-5A in excessive heat or humidity conditions or where it may be affected by direct sunlight or dust. Also avoid places subject to strong vibrations. Cabinet care Use a soft dry cloth for dusting. To remove fingerprints or dulling film, use a soft cloth slightly dampened with water and a little mild detergent. Immediately wipe dry with a soft cloth. Do not use solvents such as paint thinners. 4. Connection [1] MIDI Sockets (IN/OUT/THRU) To connect with household AC current, use only [2] DC IN socket the specified optional AC adapter (BOSS ACA series). [3] POWER ON/OFF switch 5. Operation After inserting the six batteries into the holder, press the [POWER] switch [3] to switch on the PK-5A. (1) To use the PK-5A with an AC adapter Note: Check whether the line voltage in your area meets the requirements. (optional), connect the adapter to the DC IN socket [2], located on the rear panel of the (2) Connect the adapter to a wall outlet. instrument. (3) Press the [POWER] switch [3] to switch on the PK-5A. [4] MONO mode Press the MONO selector [4] to enable the PK-5A’s monophonic mode. In that case, only one note at a time can be played. The PK-5A was designed for use with Roland’s arranger-type keyboards. By default, the MONO section therefore transmits on MIDI channel “2”, which corresponds to the “Manual Bass” (M.Bass) channel. When in MONO mode [4], the following features of the FUNCTION section are available: [9] OCT Nine different octaves can be selected via the pedals [0]~[8] (where [0] corresponds to the lowest octave and [8] to the highest). When you press the OCT selector [9], the corresponding indicator lights to inform you that the OCTAVE function is active. You can now change octaves by pressing one of the pedals [0]~[8]. All indicators briefly light to confirm your selection. [9] SELECT When you press the SELECT selector [9], the corresponding indicator lights to indicate that the SELECT mode has been activated. In that case, the following parameters can be selected. • VELOCITY (pedal [9]) If this parameter is on, your playing dynamics are translated into MIDI velocity values (0~ 127). If you switch it off, the PK-5A transmits all notes with the velocity value “64”. To switch off the VELOCITY parameter, press the SELECT selector [9] and pedal [9]. (Repeat this to switch the velocity sensitivity back on again.) All indicators briefly light to confirm your selection. • HOLD (pedal [A]) When HOLD is on, the note pressed on the pedalboard continues to sound. It is now very easy to play tied bass notes, as it is not necessary to continue to hold a pedal to obtain a suspended note. To activate the HOLD function, press the MONO selector [4]. To switch off the HOLD parameter, press the SELECT selector [9] and pedal [A] once more. All indicators briefly light to confirm your selection. r r • RETRIGGER (pedal [B]) When this parameter is on, some special effects can be obtained. When in MONO mode, the pedalboard is monophonic: if you press two pedals simultaneously, only the last note played will sound. When that note is released, the previous note will sound, so a pleasant alternating effect can be obtained. To switch off the RETRIGGER parameter, press the SELECT selector [9], then pedal [B]. All indicators briefly light to confirm your selection. • OCTAVER (pedal [C]) When this parameter is on, a note is added to each note you play. The added note is one octave above the note you played.
