Model: M-12
The Master-D Onyx Professional AV Rack M-12 is a compact and practical equipment rack designed to organise audio, video, karaoke and other compatible rack-mount devices in one dedicated location. With a 12U rack capacity, it provides useful installation space while maintaining a manageable overall size.
Instead of placing amplifiers, audio processors, wireless microphone receivers and other equipment separately on tables or shelves, the M-12 keeps the main components together in a cleaner and more professional arrangement. This helps users operate the system more conveniently while making inspection, cable management and routine maintenance easier.
A complete AV or karaoke system may contain several individual devices. These can include a power amplifier, digital audio processor, mixer, wireless microphone receiver, media player, power management unit and other control equipment.
When these components are placed loosely around the room, the system can look cluttered and may become difficult to manage. The M-12 provides a central installation area where compatible equipment can be arranged in a clear and logical order.
Each component can be assigned its own position inside the rack, making the complete system easier to understand and operate—even for users who are not familiar with professional AV equipment.
The M-12 offers a capacity of 12 rack units, commonly written as 12U. “U” is a standard measurement used to describe the installation height of professional rack-mount equipment.
Different AV devices may require different amounts of rack space. A compact microphone receiver may occupy less space, while a larger amplifier may require several rack units. The 12U capacity allows users and installers to plan the internal arrangement according to the equipment included in the system.
Its capacity makes the M-12 particularly suitable for small to medium-sized AV systems that require proper organisation without using an unnecessarily large equipment cabinet.
The M-12 has external dimensions of approximately 56cm wide, 57cm high and 60cm deep. Its compact form makes it easier to position in home entertainment rooms, karaoke rooms, meeting spaces and commercial premises where available floor space may be limited.
The 60cm depth provides practical room for compatible AV components while keeping the rack relatively compact. However, equipment depth can vary, so users should confirm the dimensions and cable clearance requirements of every device before installation.
Professional AV equipment can be sensitive to accidental impact, excessive handling and poor placement. Installing the components inside a dedicated equipment rack helps create a more controlled and organised environment.
The M-12 keeps compatible devices together and reduces the need to move them frequently. This helps lower the possibility of equipment being knocked, disconnected or handled unnecessarily during normal use.
It also prevents devices from being stacked loosely on unsuitable furniture, which can make the system unstable and restrict access to important controls or connections.
AV systems usually require multiple power, audio, microphone and signal cables. Without a proper rack, these cables can quickly become tangled or spread across the installation area.
By arranging the main equipment inside the M-12, installers can create a clearer cable route between the different components. Cables can be grouped and labelled according to their functions, making future inspection, maintenance and troubleshooting more convenient.
A properly planned rack installation also gives the overall AV system a cleaner and more professional appearance.
Correct equipment arrangement is important when building an AV system. Frequently used devices can be installed in an accessible position, while amplifiers and other components can be arranged according to their space, connection and ventilation requirements.
The 12U format makes it easier to plan the position of each compatible component before installation. Space may also be reserved for future devices, blank rack panels or ventilation gaps where required.
For the best results, the internal arrangement should be planned by a professional installer according to the equipment’s weight, operating temperature and wiring requirements.
The M-12 features a professional black appearance that complements most audio, video and karaoke equipment. Its simple and understated design allows it to fit naturally into both residential and commercial interiors.
Rather than drawing attention away from the entertainment system, the rack creates a tidy presentation that keeps the equipment together as one complete installation.
The Master-D Onyx Professional AV Rack M-12 can be used in a wide range of indoor applications, including:
Keeping all essential equipment in one rack can make the system easier to use. Each component remains in a consistent position, allowing users to locate the required controls quickly.
This is particularly useful in shared environments such as meeting rooms, karaoke rooms and commercial venues. Staff or users do not need to search for separate devices placed in different areas of the room.
A neatly arranged rack can also make it easier to identify which device controls a particular part of the system.
When equipment and cables are properly organised, technicians can inspect the system more efficiently. Individual components can be identified without moving multiple loose devices, while labelled connections are easier to trace during servicing.
The rack also creates a more consistent installation. Once the equipment has been correctly mounted and connected, it can remain in position during regular operation.
The Master-D Onyx Professional AV Rack M-12 is an ideal choice for users who need professional equipment organisation in a compact format. Its 12U capacity provides practical installation space for compatible audio and video components, while its manageable external size makes it suitable for many residential and commercial environments.
Whether used for karaoke, meetings, entertainment or general audio applications, the M-12 helps create an AV system that is cleaner, easier to operate and more convenient to maintain.
