Making Connections The DR-770 does not contain an amp or speakers. In order to produce sound, you must provide an amp or audio system, or use stereo headphones. Audio cables, MIDI cables, stereo headphones, and foot switches are not included. They can be NOTE purchased separately from your dealer.
Page 13
Connect your amp or audio system as shown in the diagram. Alternately, you could connect a set of stereo headphones. In order to take full advantage of the DR-770’s capabilities, we recommend that you play it in NOTE stereo.
Before turning on the power, check the following points. - Have connections with external devices been made correctly? - Has the volume of the DR-770 and the connected amp system been turned to the minimum position? Turn on the POWER switch located on the rear panel of the DR-770.
Restoring the Factory Settings (Factory Reset) If you have modified the settings of the DR-770 after purchasing it, it may not function exactly as described in this Quick Start manual. Should this be the case, please use the following Factory Reset procedure to restore the factory settings before you read the Quick Start manual.
