Product Overview
What makes the ML 104 Audio Splitter
The ML 104 Audio Splitter features one RCA audio input and four RCA output channels, enabling a single audio source to feed multiple audio systems at the same time. The layout is clearly labelled, making connections simple and efficient for engineers and AV installers alike.
Each output channel is designed to deliver consistent and balanced audio signals, ensuring uniform sound across all connected devices. The integrated gain control and stable signal handling allow the splitter to maintain audio quality even when all four outputs are in simultaneous use.
The device is housed in a durable metal enclosure that provides reliable protection for long-term deployment. A front-mounted power indicator provides clear operational status at a glance. The compact form factor allows easy placement on desks, AV racks, or equipment cabinets without occupying excessive space.
Setup requires no complex configuration. Connect the audio source to the RCA input port, connect up to four output devices, and the unit is operational. It integrates readily into existing audio systems including amplifiers, speakers, mixers, and AV control setups.

Installation
Simple connection. Immediate operation.
The ML 104 Audio Splitter requires no configuration or software. It connects directly to standard RCA audio equipment and is operational as soon as the input and output devices are attached.
01
Connect the Audio Source
Connect the main audio source to the single RCA input port on the ML 104 Audio. The input is compatible with standard audio devices including media players, mixers, and amplifiers. The clearly labelled input port allows for simple and centralized signal connection.
02
Connect Output Devices
Connect up to four audio output devices to the four RCA output ports. Each port is clearly marked and arranged for easy identification, making setup quick and organised. Outputs can connect to speakers, amplifiers, or other audio systems in different zones.
03
Adjust Gain Control
Use the front-mounted gain control knob to set the appropriate input signal level for your installation. Adjust until consistent volume is achieved across all outputs. This step is particularly important in setups using longer cable runs or multiple output devices simultaneously.
04
Verify Operational Status
Once connected and powered, the front-panel power indicator will confirm that the unit is operational. No drivers or software are required. The splitter is ready for continuous use immediately after installation and can be integrated into existing AV rack or desktop setups.
Where the ML 104 Audio Splitter performs
Designed for environments requiring consistent, synchronised audio distribution across multiple zones from a single source.
Retail and Commercial Spaces
Distribute background music across multiple zones within stores and showrooms from a single audio source. The ML 104 ensures uniform sound levels throughout the commercial space without requiring multiple independent sources.
Hospitality Environments
Ensure consistent audio playback across restaurants, hotels, and cafes. The splitter allows a centralised audio system to serve dining areas, lobbies, and service zones simultaneously with balanced output from a single feed.
Control Rooms
Share audio signals across multiple monitoring systems within control room environments. Operators at different positions can receive the same audio feed without any compromise to signal quality or level consistency.
AV Installations
Suitable for professional AV setups that require multiple audio outputs from a single source. The ML 104 Audio integrates easily into AV racks and centralised distribution systems used in corporate and institutional environments.
Education and Presentation Rooms
Distribute audio from a single presentation or media source to multiple speaker zones within lecture halls, training rooms, or multi-screen setups. This ensures clear and consistent audio for all participants in the space.
Broadcast and Studio Monitoring
Feed audio from a single broadcast or studio source to multiple monitoring points. The stable signal performance and low-noise output of the ML 104 make it appropriate for use in professional audio and broadcast monitoring chains.
