DriveControl‑P: the IP control panel that simplifies multi-zone audio management

In installations based on LEM Commercial D‑Drive ampli-DSPs, day-to-day system management - volume adjustment, source selection, zone control, scene recall - normally takes place through the DSP hardware and its Webcon interface. Although this hardware-software combination offers great flexibility to installers, it is often complex for end users, who have to interact with technical menus, DSP parameters and routing logic not designed for them. The result is an installation perceived as difficult to manage, requiring training, support and recurring interventions after handover.

DriveControl‑P was created to solve this problem: it moves the essential operations from the D‑Drive processor and its Webcon software to a simple, immediate and always accessible wall panel. The most used functions - volume, mute, sources, zones, scenes - are made available directly on the wall, through physical controls and a clear, customizable OLED display. In this way the end user can control the system without opening complex software, while the installer can configure the panel via browser, adapting it to the real needs of the project.

The result is an intuitive and reliable control point that dramatically reduces the need for post-installation support and improves the user experience in any commercial or corporate setting.

Why does DriveControl‑P simplify audio system management?

As mentioned, DriveControl‑P is a control panel designed to make the day-to-day operation of audio systems based on the D‑Drive series more immediate. Its purpose is not to replace the processor/amplifier, but to decentralize the functions that users use every day.

The value of the device lies in its ability to abstract the complexity of the system: instead of showing technical parameters, routing, matrices or DSP settings, the panel exposes only the functions that the end user really needs. This approach reduces errors and simplifies the experience because it limits access to critical configurations.

DriveControl‑P is also fully adaptable to the scenario: the installer can decide which controls to make available, how to organize them and which limits to apply. In this way the panel does not impose a workflow, but adapts to the needs of the project - whether it is a single room, a multi-zone environment or a complex system with scenes and priorities.

What controls does it offer and how is it used?

The panel integrates four function buttons, an ENTER rotary potentiometer, a MUTE key and an ESC key. The 2'' high-contrast OLED display - featuring a native graphic resolution of 128 × 64 pixels - shows only the useful information: zone name, active source, volume level, available scenes and system status. Navigation is intuitive: turning the selector lets you scroll through items and parameters, while pressing it confirms the action. The function buttons can be programmed to recall sources, presets, scenes or specific commands, adapting perfectly to the installation scenario.

One of the most important aspects is that the interface is not fixed: the installer decides which functions to expose and how to organize them. It is possible to create custom menus, limit access to sensitive parameters, define maximum volume levels, assign names to zones and set tailored navigation logic. In this way the panel can be configured for extremely simple use - for example three scenes and a volume control - or to manage multiple zones, sources and presets in more complex environments.

DriveControl‑P requires no technical expertise from the user: every command is immediate, every piece of information is clear and every function is easily accessible. The panel thus becomes the operational control point of the system, reducing complexity and ensuring a stable and predictable user experience.

Integration with D‑Drive processors and system logic

DriveControl‑P is designed to operate as the control terminal of the entire LEM Commercial ecosystem based on the D‑Drive series. The panel communicates via IP network and integrates directly with the processor, sharing the same management interface and the same operating logic. This means that all the functions exposed on the panel - volumes, sources, zones, scenes, presets - correspond exactly to the parameters configured in the DSP, ensuring consistency between what the installer sets and what the end user uses.

Direct control of the audio system

DriveControl-P can control:

• Volume levels and mute (with very precise master attenuation from -60 to 0 dB)
  
  
• Source selection (local analog on Phoenix terminals, AES3 digital or network AoIP streams)
  
  
• Zone routing
  
  
• Presets and scenes
  
  
• DSP functions made available by the installer

The panel does not show the technical parameters of the processor, but only what has been authorized, avoiding unwanted access to critical configurations.

Integration with third-party devices

One of the strongest points of the system is the panel's ability to control external devices via TCP/UDP protocols by sending customized hexadecimal ASCII command strings on the standard 10/100BASE-TX LAN network port. In particular:

• Video projectors
  
  
• LED displays
  
  
• Telephones and PTZ systems for videoconferencing
  
  
• Lighting systems and DALI/DMX home automation controllers
  
  
• HVAC
  
  
• Power management and power sequencers
  
  
• Centralized control systems

DriveControl-P can recall combined actions, such as lowering the projector, adjusting the lights and setting the volume with a single scene command. This turns the panel from a simple audio controller into a control point for the entire space, integrating audio, video and environment into a single operating interface.

Multi-panel management

A single D‑Drive processor can manage up to 8 Drive Control‑P panels simultaneously, all synchronized and with the same configuration. This feature is essential for multi-zone environments or complex rooms, where it is useful to have distributed control points - for example entrance, podium, control room, operator zone.

Ecosystem consistency

Drive Control‑P also shares the same Web management interface of the entire LEM Commercial system

Installation and power supply

The panel is designed to integrate easily into any commercial or corporate environment thanks to its standard 86 × 86 mm format (with a thickness of only 33 mm), compatible with the common flush-mount boxes used in Italian and European electrical systems (including three-module boxes such as the 503 type used horizontally or vertically and square 502 type boxes/technical cabinets). This choice allows it to be installed like a normal wall-mounted device, without requiring proprietary accessories or special structural work.

Connection to the network is via a single RJ45 Ethernet port, which can provide both IP communication with the DDrive processor and power via PoE technology compliant with the universal IEEE 802.3af and 802.3at standards. This mode greatly simplifies installation, reduces the required cabling and allows the panel to be powered directly from the network switch, ensuring operational continuity even in distributed installations. The electrical consumption of the hardware at full load is extremely low, limited to a value below 5 W.

When PoE is not available, Drive Control-P can be powered via an external auxiliary 12 VDC adapter, offering flexibility in contexts where the data network cannot provide power or where an independent control point is required. The dual mode allows the panel to be used both in new installations and in retrofit projects, adapting to existing infrastructures without invasive modifications.

The installation is therefore simple, clean and reliable: a standard wall-mounted device, a network cable, PoE or 12 VDC power and browser-based configuration. The result is an immediate, integrated and always available control point, perfectly aligned with the needs of professional installations.

Advanced functions and browser-based configuration

DriveControl‑P is a fully customizable interface that allows the installer to precisely define which functions to expose to the end user and how to organize the system logic.

Interface customization

The installer can shape the panel according to the real scenario, defining:

• Menu structure
  
  
• Names of zones and sources
  
  
• Functions assigned to buttons
  
  
• Volume limits and protections
  
  
• Maximum and minimum levels for each zone (preventing the user from overdriving the power amplifiers)
  
  
• Available scenes and related actions
  
  
• Page layout and navigation logic

Scene management

Scenes are one of the most powerful elements of the system. DriveControl‑P can recall scenes that combine:

• Audio levels
  
  
• Routing
  
  
• Mute and priority
  
  
• Sources
  
  
• DSP presets
  
  
• TCP/UDP commands to external devices

A single scene can therefore configure the entire environment: audio, video, lighting, HVAC, displays, projectors. The panel thus becomes a control point for the space, not just for audio.

Integration with third-party devices (TCP/UDP)

Browser-based configuration allows TCP/UDP commands to external devices to be assigned to buttons or scenes.

This makes it possible to create complete workflows: a single command can lower the projector, switch on the lights, set the volume and recall the correct source.

User and permission management

The system allows different access levels to be defined through an encrypted system protected by a 4-digit numeric password: administrator, installer, advanced user, basic user.

Each role can have limited or extended functions, ensuring security and operational stability.

Themes, languages and graphic customization

DriveControl‑P supports graphic themes, multiple languages, logo upload, background upload, display appearance customization.

These options allow the panel to be adapted to the client's visual identity or the architectural context.

Backup and firmware updates

The Web platform allows:

• Complete configuration backup
  
  
• Quick restore
  
  
• Panel firmware updates
  
  
• Synchronization with the D‑Drive processor

This guarantees operational continuity and makes maintenance easier over time.

Fields of use

• Conference rooms and meeting rooms: immediate use for speakers and guests, with clear controls for volume, sources, scenes and external devices, without accessing the processor software
  
  
• Classrooms and training environments: simple interface for teachers and operators, ideal in contexts with high turnover or where quick and protected control of essential functions is required
  
  
• Corporate spaces and offices: consistent audio management in reception areas, open spaces and meeting rooms, with volume limits, predefined sources and scenes configured for daily use
  
  
• Hotels, resorts and hospitality facilities: perfect for event rooms, banquet rooms and meeting rooms, where a single command can recall scenes that combine audio, lights, video and environmental devices
  
  
• Commercial audio systems: shops, showrooms, restaurants and bars can control zones, levels and sources immediately, reducing operational complexity for staff
  
  
• Multi-zone installations: the possibility of distributing up to eight panels per processor, with control points in entrances, podiums, control rooms or adjacent rooms, always maintaining the same operating logic

Conclusions

DriveControl‑P represents a concrete evolution in the way users interact with professional audio systems. By bringing day-to-day operations to the wall, the panel eliminates the need to access the processor software and reduces the operational complexity that often generates errors, support requests and unexpected costs. Its strength lies not only in the physical controls, but in its ability to adapt to the project: menus, names, functions and limits are defined by the installer, allowing simple interfaces for non-technical users or more detailed panels for complex environments, without having to resort to rigid templates or custom development.

The ability to control third-party devices via TCP/UDP further expands its role: a single command can manage audio, lights, video, HVAC and environmental devices, turning the panel into the control point for the entire space and not just the audio system. Native integration with the LEM Commercial ecosystem, management of up to eight panels per processor and sharing of the same Web platform used for DSP, amplification and distribution ensure consistency, stability and operational continuity over time.

Ultimately, DriveControl‑P is much more than an accessory: it is the terminal that determines the perception of the entire system. It is what the user touches every day, what makes the installation simple, reliable and immediate, and what allows the integrator to deliver a project that continues to work without requiring constant intervention.
