Marantz AV Receiver Control Spec

Summary

Marantz AV Receiver with RS-232 and TCP/IP (Telnet) control. The protocol uses ASCII command strings terminated by carriage return (0x0D). Covers power, volume, input selection, surround modes, zone 2/3 control, tuner, and online music/USB/Bluetooth playback. This spec is derived from the Denon/Marantz AV Receiver Control Protocol document, which shares the same command set across Marantz and Denon models.

Notes

• All commands use ASCII encoding terminated by carriage return (CR, 0x0D).
• Commands should be sent at 50ms or greater intervals.
• Maximum communication data length is 135 bytes.
• Volume encoding: 2-char for whole dB steps (80=0dB, 00=MIN/---dB), 3-char for 0.5dB steps (e.g. 805=+0.5dB, 795=-0.5dB).
• Channel volume range: 38-62 (50=0dB) per channel. Subwoofer: 00, 38-62.
• Events are sent within 5 seconds of a state change. Query responses within 200ms.
• When input source changes, channel volume and surround mode events are sent if they differ from the previous source.
• "Network Standby" must be set to "Always On" for IP control while in standby.
• The source document title is "Denon AV Receiver Control Protocol" but this same protocol applies to Marantz AV receivers.
• RS-232 connector is DB-9pin female (DCE type), pins 1(GND), 2(TxD), 3(RxD), 5(Common).
• TCP connection uses port 23 (Telnet), 10BASE-T/100BASE-TX via RJ-45.
