lyngdorf 1.3.3

Library to control a Lyngdorf A/V processor

Lyngdorf Audio Control Library

Python library to control Lyngdorf A/V processors and integrated amplifiers over TCP/IP (port 84).

Supported Models

MP Series (Multichannel Processors)

• MP-40 - Entry-level processor (3 HDMI inputs, 12-channel decoding)
• MP-50 - Mid-level processor (8 HDMI inputs, 11.1 + 4 aux)
• MP-60 - Flagship processor (8 HDMI inputs, 16-channel decoding)

TDAI Series (Integrated Amplifiers)

• TDAI-1120 - Entry-level integrated amplifier
• TDAI-2170 - Older integrated amplifier model
• TDAI-3400 - Top-of-line networked integrated amplifier

All models support:

• Power control
• Volume/mute control
• Source selection
• RoomPerfect™ room correction
• Voicing selection
• Trim controls (bass, treble, center, height, LFE, surround)
• Zone B control (MP series)

Installation

From PyPI

pip install lyngdorf

From Source

git clone https://github.com/fishloa/lyngdorf.git
cd lyngdorf
poetry install

Quick Start

import asyncio
from lyngdorf import async_create_receiver, LyngdorfModel

async def main():
    # Auto-detect model (recommended)
    receiver = await async_create_receiver("192.168.1.100")

    # Or specify model explicitly
    receiver = await async_create_receiver("192.168.1.100", LyngdorfModel.MP_60)

    # Connect to the receiver
    await receiver.async_connect()

    # Control the receiver
    receiver.power_on(True)
    print(f"Volume: {receiver.volume} dB")
    receiver.volume = -22.5
    receiver.mute_enabled = False

    # Change source
    receiver.source = "HDMI 1"

    # RoomPerfect control
    receiver.room_perfect_position = "Focus 1"

    # Disconnect when done
    await receiver.async_disconnect()

asyncio.run(main())

Usage Examples

Power Control

receiver.power_on(True)   # Turn on
receiver.power_on(False)  # Turn off
print(receiver.power_on)  # Check power state

Volume Control

receiver.volume = -25.0   # Set volume in dB
receiver.volume_up()      # Increase volume
receiver.volume_down()    # Decrease volume
receiver.mute_enabled = True  # Mute

Source Selection

# List available sources
print(receiver.sources)

# Select source by name
receiver.source = "HDMI 1"

# Or by index
receiver.change_source(1)

RoomPerfect™ & Voicing

# List available positions
print(receiver.room_perfect_positions)

# Select position
receiver.room_perfect_position = "Focus 1"
receiver.room_perfect_position = "Global"
receiver.room_perfect_position = "Bypass"

# List available voicings
print(receiver.voicings)

# Select voicing
receiver.voicing = "Neutral"

Trim Controls (MP Series)

# Adjust trim levels (in dB)
receiver.trim_bass(1.5)      # +1.5 dB
receiver.trim_treble(-0.5)   # -0.5 dB
receiver.trim_centre(0.0)    # Reset to 0 dB
receiver.trim_height(2.0)
receiver.trim_lfe(-1.0)
receiver.trim_surround(0.5)

# Or use increment/decrement
receiver.trim_bass_up()
receiver.trim_bass_down()

Zone B Control (MP Series)

# Zone B power
receiver.zone_b_power_on(True)

# Zone B volume
receiver.zone_b_volume = -30.0
receiver.zone_b_volume_up()
receiver.zone_b_volume_down()

# Zone B source
receiver.change_zone_b_source(2)

Callbacks & Events

# Register for volume changes
def on_volume_change(param1, param2):
    print(f"Volume changed: {param1}")

receiver._api.register_callback("VOL", on_volume_change)

# Register for any change notification
def on_any_change():
    print("Receiver state changed")

receiver._api.register_notification_callback(on_any_change)

Protocol Documentation

All models communicate via TCP/IP on port 84 using ASCII commands:

• Commands start with ! and end with \r
• Format: !COMMAND(parameter)\r or !COMMAND?\r for queries
• Responses start with ! for status messages

Protocol details available in the /spec folder.
