CONNECTIONS

• Setting Up and Applying Power
  The DX7 does not have an internal power amplifier, therefore either headphones or an external amplifier/speaker system are required.  A high-quality keyboard amplifier system is recommended.
  Hook up your DX7 as shown in the diagram below.
  
  
  
• Turn POWER ON
  The DX7 power switch is located to the right side of the rear panel (viewed from keyboard side).  Turn the power switch on only after all connections to other equipment (and to the AC supply) have been properly made.  The display panel will appear as in the illustration below immediately after power is switched on.
  After a few seconds, the same mode that was engaged before power was turned off is re-engaged.  For example, if the PLAY mode was previously engaged, the PLAY mode will be re-engaged and the previously selected voice will be ready for performance.  The same applies to the EDIT and FUNCTION modes.
