Porter & Davies BC2RM Tactile Monitoring System
The Porter & Davies BC2RM is a professional rack-mountable tactile monitoring system designed to provide drummers and musicians with physical low-end feedback. By utilizing a patented throne top with an integrated tactile generator, it allows performers to feel the weight and impact of their instrument without relying solely on high-volume auditory monitoring.

Overview
The Porter & Davies BC2RM represents a specialised evolution of the standard BC2 system, specifically adapted for professional touring rigs and studio installations. As a tactile monitoring solution, it translates low-frequency signals—typically from a kick drum or bass guitar—into physical vibrations. This allows the user to experience the 'thump' and timing of their performance internally, rather than through external air pressure or loud monitor wedges.
The system is comprised of two primary components: a 19-inch rack-mountable engine unit and a patented Porter & Davies throne top. The 'RM' designation signifies its rack-mount compatibility, offering the same internal technology as the portable BC2 unit but in a form factor that integrates seamlessly into standard equipment racks.
Key Features and Hardware
The heart of the system is the internal tactile generator housed within the saddle-style throne top. Unlike traditional 'shakers' which are often bolted to the exterior of a seat, the Porter & Davies generator is built into the cushioning to provide maximum conduction and response speed.
Features of the BC2RM include: * Rack-Mountable Engine: A robust unit designed to fit into a standard rack, protecting the electronics during transport. * Patented Throne Top: A purple saddle-style seat featuring high-quality foam and the integrated transducer. * Connectivity: The package includes all necessary specialist cabling to link the engine to the throne and power the system. * Precision Control: The engine allows the user to adjust the intensity of the tactile feedback to suit the specific environment, whether it be a quiet studio session or a loud stage.

Sound Character and Performance
While the BC2RM does not produce audible sound in the traditional sense, it significantly alters the user's perception of their instrument's character. It provides a bone-conduction experience that is described as transparent and instantaneous. There is no latency between the strike of a drum and the sensation felt through the throne. This physical feedback enables drummers to play with greater confidence and dynamic control, as they can 'hear' their kick drum through their body even when the stage volume is high or when using isolating in-ear monitors (IEMs).
Target User and Comparison
The BC2RM is primarily aimed at professional drummers who use rack-based setups for their monitoring and playback. It is also highly effective for bass players and keyboardists who perform seated. Compared to the standard BC2, which comes in a flight-case style 'briefcase' engine, the BC2RM is better suited for fixed installations or touring professionals with dedicated rack real estate.
When compared to traditional sub-low monitoring (subs and wedges), the BC2RM offers a silent alternative that reduces stage volume and ear fatigue. While accessories like the Tama Accu-Strike beater or Evans MS3 heads can change the acoustic attack of a drum, the BC2RM addresses the physical connection the drummer has with their instrument's low-end frequencies.

Frequently asked questions
- What is the main difference between the BC2 and the BC2RM?
- The primary difference is the engine housing. The BC2RM is designed to be mounted in a standard 19-inch equipment rack, whereas the standard BC2 is built into a self-contained flight case.
- Does the system come with the throne base/tripod?
- The package includes the patented Porter & Davies throne top and the engine, but users typically need to provide their own compatible throne base (tripod) unless specified.
- Is the saddle top available in other colours?
- This specific model features a Purple finish, though Porter & Davies produces various configurations across their product line.
- Can the BC2RM be used with electronic drums?
- Yes, it is highly effective with electronic kits as it restores the physical sensation of a kick drum that is often missing when playing pads.
- What cables are included in the package?
- The system includes all necessary cables to connect the rack engine to the throne top and the power cable for the main unit.
- How does the tactile generator differ from a standard bass shaker?
- The Porter & Davies generator is a patented, high-speed unit integrated directly into the throne's upholstery for superior conduction and zero latency, unlike many bolt-on shakers.
- Can I use this for instruments other than drums?
- Absolutely. Bass players and keyboardists often use the system to feel their low-end frequencies while performing seated.
- Does the system require an external amplifier?
- No, the BC2RM engine contains its own dedicated power amplification specifically tuned for the tactile generator in the throne.
- What is the benefit of the saddle-style top?
- The saddle shape is designed for ergonomic comfort and freedom of leg movement, which is preferred by many professional drummers for long performances.
- Is the system voltage-switchable for international touring?
- Porter & Davies engines are typically built to high professional standards for touring, but users should check the specific voltage requirements on the rear panel for different regions.
- Does it work well with In-Ear Monitors (IEMs)?
- Yes, it is considered a perfect companion for IEMs, as it provides the physical 'thump' that earplugs and headphones naturally remove.
- How much rack space does the engine unit occupy?
- The BC2RM engine unit is designed to occupy 2U of space in a standard 19-inch equipment rack.
