LEA 124N Control Spec

Summary

Network Connect Series professional amplifier (4-channel, low-Z/Hi-Z). TCP/IP control protocol on port 4321 using ASCII command strings terminated by newline. Supports GET / SET / SUBSCRIBE / UNSUBSCRIBE against a hierarchical URL-based object/element namespace covering channel inputs, crossover, EQ, limiters, output, levels, load monitor, device info, power supply, auto-standby, and signal generator.

Transport

protocols:
  - tcp
addressing:
  port: 4321
auth:
  type: none  # inferred: no auth procedure in source (doc states TCP works even if WebUI is password-protected)

Traits

- powerable       # inferred from output enable / channel-ready commands and auto-standby commands
- routable        # inferred from primary/secondary input source selection commands
- queryable       # inferred from GET commands returning state
- levelable       # inferred from fader, gain, EQ, and threshold control commands

Variables

# No additional settable scalar variables beyond what is captured in Actions.

Events

# SUBSCRIBE commands produce asynchronous notifications on the same TCP connection.
# Notification payload format mirrors the GET response: "<object/element> <value>\n".
# Examples:
#   /amp/channels/1/levels/level_db -52.78131103515625\n
#   /amp/channels/1/inputSelector/danteOnRamp "Post Crossover"\n

Macros

# UNRESOLVED: source does not define multi-step macro sequences

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains power-supply fault/thermal protection sensors but no explicit
# safety interlock procedures or confirmation requirements

Notes

Source document covers the LEA Connect Series protocol (Network Connect and Dante Connect). The LEA 124N is a 4-channel Network Connect Series amplifier with no Dante inputs. Per the source, Network Connect Series supports only Analog inputs (limited to the number of channels on the amplifier) and Dante elements are not applicable to a 124N.

• TCP port: 4321 (verified). All messages are newline (0x0a) delimited. Out-of-range numeric values are clamped silently. Illegal commands produce error: ... responses.
• Auth: source states TCP communication works even if the WebUI is password-protected; no auth handshake is documented.
• Firmware: source states "LEA Connect Firmware version 1.1.0.29 and higher" supports TCP; earlier versions only support WebSocket. Per-device firmware for the 124N itself is not stated.
• For Network Connect Series, Dante-related elements (Dante sources, danteOnRamp) are not applicable.
• Crossover high-pass filter URL is sometimes given with lowPassFilter in the source's HP filter type example — likely a doc typo; URL follows element name highPassFilter.
• /amp/deviceInfo/venueName example response in source shows a model ID value ("Connect Series Model 704D") — likely doc typo; URL is /amp/deviceInfo/modelID per the "Model ID" section.
• get /amp/powerSupply/fault example response shows the acLineWatts URL — likely doc typo; expected response is the fault boolean value.
• get /amp/channels/1/loadMonitor/measuredImpedance example response shows /amp/channels/1/level — likely doc typo; expected response is the impedance value.
• get /amp/channels/1/loadMonitor/status example response shows /amp/channels/1/level — likely doc typo.

summary: "All 98 spec actions matched verbatim to source URLs; transport parameters (TCP port 4321, no auth) verified. (4 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "spec applies to LEA Connect Series broadly (Network and Dante Connect); per-channel URL uses \"x\" and input uses \"#\" placeholders that depend on the specific amplifier model. 124N is a 4-channel Network Connect Series amplifier. Source does not enumerate channel counts or per-model availability for each element — see Notes."
- "source does not define multi-step macro sequences"
- "source contains power-supply fault/thermal protection sensors but no explicit"
- "source describes the protocol generically for all Connect Series models; device-specific channel count, available inputs/outputs, and per-model element availability for the 124N must be confirmed from LEA product documentation."
