IBM PS1500 owner manual Power Supply, Output, Pedals, Midi, Right/Mono, Left

Connections

•Disk (file handling operations to and from

RAM and disk).

The various Edit modes are explained in detail in the relevant chapters of the owner’s manual.

The group of three pedals is connected to the appropriate jack via the special cable that runs from the pedal group assembly. Check that the cable is properly connected to the PEDALS jack for the correct operation of the three pedals.

Connections

This section takes a brief look at the types of con- nections that can be achieved with your PS1500 using the rear-panel connectors.

The pedals, denoted P1 (Soft), P2 (Sostenuto), P3 (Damper) are preset to provide the following three functions:

Soft Soft Pedal (generates CC67);

Sostenuto Sostenuto (generates CC 66);

Damper Damper (generates CC64).

POWER SUPPLY

Insert the instrument’s power cord into a suitable grounded outlet.

OUTPUT

Right/Mono, Left

Right - Left Stereo outputs for amplified speak- ers, amplifiers or domestic hi-fi units.

▶WARNING - Before connecting the outputs, be sure that the volume of the external amplification devices is turned down. Connecting to the jacks causes noise which can damage an amplification device.

For stereo reproduction, use both LEFT and RIGHT jacks. For mono reproduction, use only the RIGHT/M jack.

To use the audio outputs only and exclude the instrument’s internal amplification, plug a set of headphones into the left HEADPHONES 1 jack.

PEDALS

The pedals are function assignable and can be independently programmed to react with the key- board tracks of a Preset.

All three pedals are of the switch action type.

MIDI

PS1500 is fitted with a standard MIDI interface consisting of In, Out and Thru ports for MIDI con- nections. Specific instructions for MIDI connec- tions are found in the relevant chapters further ahead. The following setups show some of the principal connections.

•To pilot another instrument with PS1500, connect the PS1500 MIDI OUT to the MIDI IN of the other instrument.

PS1500	EXPANDER
MIDI OUT	MIDI IN

•To pilot PS1500 by a master keyboard, connect the PS1500 MIDI IN to the MIDI OUT of the master keyboard. If the master key- board has to simulate the PS1500 keyboard, the master keyboard must transmit MIDI on
