Marantz AV 10 Series Control Spec

Summary

The Marantz AV 10 Series is a high-end A/V preamplifier/processor controllable via RS-232C serial and TCP/IP (Telnet on port 23). The protocol uses ASCII command strings terminated with carriage return (0x0D). Commands cover power, volume, input selection, surround modes, zone 2/3 control, tuner, network/USB playback, video output, tone control, and system settings. This protocol is shared with Denon AV receivers.

Notes

• The protocol document is titled "Denon AV Receiver Control Protocol" — Marantz and Denon share the same control protocol under their common parent company. The Marantz AV 10 Series uses this identical protocol.
• Command format is ASCII: COMMAND + PARAMETER + CR (0x0D). Command is always 2 characters; parameter is up to 25 characters.
• Query format: append ? as the parameter (e.g. PW?<CR>). Response should arrive within 200ms.
• Volume encoding uses a non-linear ASCII scheme: 00=---(MIN), 80=0dB, 98=+18dB. Half-dB steps use 3 characters (e.g. 805=+0.5dB).
• Channel volume encoding is linear: 38-62 with 50=0dB.
• When input source changes, surround mode and channel volume events are sent only if they differ from the previous source's values.
• EVENTS should be sent within 5 seconds of state change. RESPONSES to queries should be sent within 200ms.
• The device supports RS-232C (DB-9 female, DCE) and TCP/IP (Telnet port 23) simultaneously.

Known Gaps

- "source document title references Denon; Marantz-specific command differences (if any) are not documented"
- "firmware version compatibility not stated in source"
- "full list of PS (parameter setting) commands for Audyssey, room size,"
- "no explicit multi-step macros described in source"
- "no explicit safety interlock procedures documented in source"
- "source references Denon model numbers (X1100, S700, X4100) in parameter notes — unclear which features apply specifically to Marantz AV 10 Series"
- "no firmware version range specified for command compatibility"
- "Auro-3D commands marked as \"Auro-3D Upgrade only\" — unclear if AV 10 Series includes this natively"
- "HDRADIO, PANDORA, SIRIUSXM, SPOTIFY, LASTFM, FLICKR availability may vary by region"
