AUDIOPATCH

1 · Introduction

AUDIOPATCH is a browser-based planning app for signal routing in live productions. The app maps the complete signal flow from stage to console input — including split, multicore allocation, digital snake routing and IEM/RF frequency planning.

Who is this for?

3-Layer Model

2 · Quick Start

2. New Project — Click the AUDIOPATCH logo → "+ New Project"
3. Choose Template — „Band 48 CH" for a typical touring rider
4. Configure Hardware — ⚙ Setup → select console and stageboxes
5. Inputs patchen — Stage Inputs are automatically populated from the stagebox
6. Assign Looms — „🔗 Auto Loom Patch" distributes channels across multicore cables
7. Export PDF — ⬇ Export → PDF for the crew

3 · Navigation & UI

Sidebar (Left)

Tab Bar (Top)

Since v1, AUDIOPATCH uses custom SVG pictograms instead of emojis for tabs:

Position Page (Main View)

Each position has a split view:

Sub-Tabs

• All — Shows all channels across all stageboxes (for interface positions: all digital patch connections stacked)
• [Stagebox Name] — Only channels of this stagebox
• [Slot/Connection] — e.g. "MADI 128ch ↔ MON" or "Dante 64ch" — digital connection tabs
• Local — Local analog and AES channels of the console

4 · Project Management

Create New Project

1. Click the AUDIOPATCH logo in the sidebar
2. "+ New Project" → enter name
3. Choose Template:
   • Empty — Empty project
   • Band 24 CH — Standard band, 24 split channels
   • Band 48 CH — Full setup with playback, UHF, timecode
   • Festival — Like 48 CH + additional MON2 position

Project Details

In the Projects drawer at bottom: Name, Artist, Venue, Date. All fields appear in the PDF header.

Duplicate Project

Right-click a project → "Duplicate". Creates a full copy with a new name. Perfect for tours: same setup, new venue.

5 · Hardware Setup

Open the Setup drawer (⚙) → Hardware Setup.

Choose Console

Each position has its own console. The dropdown shows: Manufacturer → Model (In/Out + AES)

Supported manufacturers: Allen & Heath, Avid, Behringer, DiGiCo, Lawo, Midas, Soundcraft, SSL, Waves, Yamaha — totalling 82 consoles in the database.

The console determines:

• Number of Local Analog In/Out (built-in at the surface)
• Number of Local AES In/Out (built-in AES connectors)
• Expansion Slots (MY, DMI, D21m — depending on manufacturer)

Configure Stageboxes

1. Click "+ Add Stagebox"
2. Select model (filtered by console compatibility)
3. For modular stageboxes (e.g. DiGiCo SD-Rack): configure I/O cards
4. For MixRacks (e.g. A&H DM64): assign I/O slots (Dante, MADI, gigaACE)

Set Split Master

The Split Master defines the shared stage input list and has preamp authority (Gain Master). Typically: MON is Split/Gain Master — the monitor engineer controls the preamps, as consistent levels are needed for IEM. FOH works as slave with trim compensation.

6 · Stage Inputs & Patching

Adding Channels

• With stagebox: Channels are automatically created from the stagebox size
• Without stagebox: Manually via "+ Add" or "📋 Import List"

Import List (Copy & Paste)

1. Click „📋 Import List"
2. Paste channel list (one line per channel)
3. Format: Name or Name <Tab> Mic <Tab> Info
4. Mode: Overwrite / Append / Fill empty only

Input Table Columns

Context Menu (Right-click)

• Duplicate — Creates a copy below the channel
• Swap — Exchange two channels (Shift+Click on second channel)
• Clear — Clear channel name and mic
• Delete — Remove channel

Stereo Pairs

1. Shift+Click on two adjacent channels
2. Right-click → "Declare as stereo pair"
3. 🔗 Symbol appears between rows
4. Auto Loom Patch keeps stereo pairs in the same loom
5. IEM Planning: Stereo pairs in outputs are „Auto-Generieren" automatically recognized as stereo IEM channel in the IEM/RF tab

7 · Outputs & Monitor-Sends

8 · Local I/O & AES

Each console has local connectors on the surface/rack, managed separately:

• Local Analog In — Physical inputs on the console (e.g. FOH stage mic, talkback)
• Local Analog Out — Physical outputs (e.g. shoutbox, DiOut TC, matrix)
• Local AES I/O — AES/EBU connections with direction (In/Out), signal and loom

9 · Loom System

Loom Types

Colors (Resistor Color Code)

Auto Loom Patch

„🔗 Auto Loom Patch" distributes channels automatically according to configurable rules:

• Group by stage position — Drums in one loom, keys in another
• Keep stereo pairs together — L/R end up in the same loom
• Keep existing assignments — Only empty channels are filled
• Fill from top — Fills looms from CH 1 upward

Rules configurable under ⚙ Setup → App Setup → Auto-Loom Rules.

Loom Fill-Down

Click the colored dot at the bottom right of the loom cell, then drag downward → fills following channels with ascending loom channels. AES channels are skipped.

10 · Split Configuration

The split defines how stage signals are distributed to multiple positions.

Split Types

Gainsharing

For digital splits, a gainsharing mode is set per connection in Hardware Setup:

• Off — Each position has independent preamps (default for transformer/active splits)
• Gain Tracking — The Gain Master controls the preamps, slave positions automatically compensate via trim

The Gain Master is configured per connection. In typical touring setups, MON is the Gain Master to ensure consistent IEM levels.

Slave Position (v1)

Special rules apply to slave positions:

• Read-Only Stage Inputs — Name, Mic, Position and Info fields are not editable. Data is automatically synced from the Split Master.
• Split-Channel Dropdown — Shows available master channels with signal names (e.g. "Split 01 — Kick In" instead of just „1"). Makes assignment significantly easier.
• AES Restriction — AES/EBU inputs on stageboxes cannot be assigned to an analog split, as this is physically not possible.

11 · Patch Overview

The Patch tab shows all positions side by side: Split matrix, loom assignment, channel status and conflicts at a glance.

Avantis CSV Export

For Allen & Heath Avantis: Direct CSV export in Avantis Director format. Import via File → Import CSV in the Director software.

12 · Digital Patch & Connections

Digital connections between positions (MADI, Dante, gigaACE, Optocore, AES50 etc.) are configured via Digital Patch tabs. Each connection has its own sub-tab with protocol and channel count.

Structure

Each digital patch tab shows two columns:

TX Auto-Patch

The ↑ TX Auto-Patch button automatically fills TX labels from the stage input list:

1. Stage inputs are sorted by loom letter and loom channel
2. TX channels 1–N are filled sequentially with signal names
3. TX source is automatically set to the corresponding stage input

TX Source Dropdown

Each TX channel has a dropdown to link to a stage input. The dropdown shows:

• Empty entry — No source assigned
• Stage inputs — e.g. "SI 01: Kick In" — automatically sets the TX label

RX Receive

The right column shows the incoming signals from the partner position. This data is automatically synchronized — e.g. if MON defines TX labels, they appear on FOH as RX Receive.

Clear All

Clears both directions (TX and RX) of the digital connection. Secured by confirmation dialog. Also undoable.

RGB / RX Buttons

13 · Recording / Interface Positions

Interface positions (e.g. REC, Broadcast) are positions without physical stageboxes. They receive their signals exclusively via digital connections (MADI, Dante).

Special Features

• No stagebox tabs — Instead the tab bar shows the slot connections (e.g. "MADI 128ch ↔ MON", "Dante/AES67 64ch")
• Default Tab — The first slot tab opens by default (instead of "All")
• „Alle" Tab — Shows all digital patch connections stacked, with own header, TX Auto-Patch and Clear All per connection
• Scrollbar for multiple connections — Max. 500px height per table, scrollable on overflow

Typical Setup

14 · Loom Planner

The Loom tab shows all multicore assignments sorted by loom letter:

• Each loom as a separate table with channel assignment
• Inputs AND Outputs in one overview
• Basis for the physical assignment plan (Sub-D/EtherCon connectors)
• Automatically generated from loom assignments

15 · IEM / RF Planner

IEM Channels

Per IEM channel configured:

UHF Microphones

Auto-Generate

„Auto-Generieren" automatically creates IEM channels from monitor outputs. Stereo output pairs are recognized and combined as stereo IEM.

16 · Pack List

The Pack List tab automatically generates an equipment list:

• Consoles and stageboxes per position
• Cable quantities (multicore, Sub-D, EtherCon)
• Microphones and DI boxes from stage inputs
• IEM transmitters and receivers
• UHF receivers

17 · Export & Import
