4— Panel Descriptions
2—REAC MODE Switch
This switch sets the S-4000H's REAC device behavior.
• M—This configures the S-4000H as a Master REAC device.
• S—This configures the S-4000H as a Slave REAC device.
• SP—This configures the S-4000H as a Split REAC device.
The REAC MODE switches must be set properly for the system to work. See Chapters 6 and 7 for
information on configuring the system and setting the REAC MODE switches.
3—MIDI Jacks
MIDI jacks are provided for the connection of MIDI devices.
• MIDI IN—Connect the MIDI output of an external MIDI device to this jack.
• MIDI OUT—Connect this jack to the MIDI input of an external MIDI device.
See Chapter 7 for information about transmitting MIDI data through REAC.
4—REMOTE Connector
This D-Sub 9-pin female connector is provided for remote control and signal monitoring of the S-4000
System from an external device supporting the RS-232C serial interface protocol. Normally, you'd
connect the S-4000R Remote Controller to this connector using the supplied DB-9 cable. If you're
using the S-4000 RCS on a computer, connect the computer's RS-232C port to this connector.
See Chapters 6 and 7 for information about remote control of the S-4000 System.
See Appendix B: Connector Information for a diagram of the REMOTE (RS-232C) connector.
5—System Status Indicators
• REAC—This indicator lights when REAC communication is established within the S-4000 System.
If REAC communication fails, this indicator will flash.
• CTRL—This indicator shows the communication status of RS-232C devices (such as the S-4000R)
connected to the S-4000 System. See Page 62 for more information.
6—MUTE ALL OUTPUTS Button
The MUTE ALL OUTPUTS button is a momentary switch used to temporarily mute the S-4000 System's
audio outputs. This allows for noise-free connection of audio input sources.
