Summary

The RSP-1576/RSP-1576MKII is a stereo preamp/processor supporting both RS-232 and TCP/IP ASCII control. Commands are terminated by !. No authentication required. IP control note: responses are slower when Front USB input is selected.

Variables

# UNRESOLVED: no discrete settable parameters beyond Actions; volume and trim
# handled via Actions with immediate feedback response.

Events

# UNRESOLVED: no unsolicited event descriptions in source; device sends
# responses only on command/query, no autonomous status broadcasts described.

Macros

# UNRESOLVED: no multi-step macro sequences described in source.

Safety

confirmation_required_for:
  - factory_default_on  # inferred: factory reset is destructive
interlocks: []
# UNRESOLVED: no safety interlock procedures stated in source.

Notes

  • Command terminator: ! on all commands. No carriage return or line feed.
  • RS-232: no flow control; packet loss possible if data sent too fast.
  • IP control: responses slower when Front USB input selected; RS-232 recommended for systems using Front USB.
  • Variable-length responses use byte count prefix before ! terminator.
