AI4AVSummary
Sennheiser EW-DX EM 2 / EM 2 Dante / EM 4 Dante rack receivers, controlled via Sennheiser Sound Control (SSC) — an OSC-derived protocol using JSON message encoding over UDP/IP. Covers device identity, network configuration, RF channel management (1–4 receiver channels depending on model), audio output levels, metering, transmitter mate telemetry, and subscriptions.
Transport
protocols:
- udp
- osc
# SSC = OSC-derived JSON-encoded messages carried in UDP/IP datagrams.
# EW-DX server supports UDP/IP only (no TCP). IPv4 only.
addressing:
port: 45
# default UDP port per source; SHOULD be discovered via DNS-SD (_ssc._udp)
discovery:
type: dns_sd
service_type: _ssc._udp
auth:
type: none # inferred: no auth procedure described in source
Traits
# - levelable # inferred from gain/frequency/level settable numeric ranges
# - queryable # inferred from null-argument getter pattern documented throughout
# - muteable # inferred from rx/mute commands per channel
Actions
# Each action = one documented SSC method address. SSC uses JSON object form
# with property path matching the OSC address. Getter = null argument.
# Dante-exclusive methods apply to EW-DX EM 2 Dante and EW-DX EM 4 Dante only.
# EM 4 Dante-exclusive methods (rx3/rx4, booster) apply to EW-DX EM 4 Dante only.

Events
# SSC subscription notifications: server pushes value-change updates for subscribed
# addresses. Default behaviour = notify on change only; optional min/max/count/lifetime
# parameters control rate and lifetime.
#
# Subscribe via: {"osc":{"state":{"subscribe":[ {"#":{"min":0,"max":0,"count":1000,"lifetime":60}},
# <address_tree> }]}}
#
# Documented push categories:
- id: subscription_notification
trigger: subscribed address value change
payload: SSC Method Reply mirroring the subscribed address tree
notes: "Up to 8 concurrent clients on EM 2."
- id: subscription_terminated
trigger: lifetime/count expires or connection close
payload: error code 310 - subscription terminated
Macros
# No multi-step macros documented in source.
Safety
confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no safety warnings, interlock procedures, or
# power-on sequencing requirements specific to EW-DX EM. Only behavioural notes:
# - /device/link_density_mode causes a device reboot
# - /device/restart restarts the device
# - /device/restore with FACTORY_DEFAULTS wipes configuration
# These are operational side-effects, not safety interlocks.
Notes
- SSC = Sennheiser Sound Control; OSC-derived application protocol using JSON encoding instead of binary OSC blobs. One UDP datagram = one SSC message.
- Setter pattern:
{"path":{"leaf":value}}. Getter pattern: same withnullargument. Server replies with adapted/actual value. - EW-DX EM 2 supports rx1/rx2 + audio1/out1/out2 + mates/tx1/tx2. EW-DX EM 4 Dante adds rx3/rx4, out3/out4, mates/tx3/tx4, /device/booster.
- Dante variants add /device/network/dante/* subtree.
- Discovery via DNS-SD/Bonjour service type
_ssc._udp; clients SHOULD NOT assume default port 45. - Error codes 100–503 defined in source (section 10). Error 424 = "failed dependency" used when TX bodypack is absent.
- SSC string charset restricted to ASCII 32–126 plus escapes
\b \f \r \n \t; no\uXXXXunicode escapes.

summary: "All 249 spec action units have exact SSC address-path matches in the source EW-DX EM method list; transport port 45 and DNS-SD discovery explicitly stated. (6 unresolved item(s) noted in Known Gaps.)"
Known Gaps
- "source also documents the CHG 70N-C charger (separate product, section 11–14); not enumerated here as compatible_with.models lists only EM receivers."
- "bay_state documented only under CHG 70N-C chapter; not enumerated for EM."
- "source contains no safety warnings, interlock procedures, or"
- "source also documents CHG 70N-C / CHG 70N charger (sections 11–14). That product is out of scope for this EM receiver family spec; a separate spec should be authored if charger control is needed."
- "TCP transport is referenced generically in the SSC framework chapter but the EW-DX server explicitly supports UDP/IP only."
- "exact device voltage / power / current specifications not present in this developer guide."
