Situated at Constitutional Hill in Johannesburg is a world-class music recording studio designed with high end acoustics and recording system in a heritage site.

MMPS was approached by Nandos to design, build and commission a recording facility that would rate as one of the best in South Africa. Constitution Hill was chosen as the home for the studio complex. The design and supply included all aspects of the recording studio including the acoustic works, the mechanical and electrical works as well as the recording system. MMPS utilised their internal engineers and experienced project managers with their network of specialised engineers, suppliers and contractors to design, build and manage the entire project for start to finish.

Being a heritage site brought along a number of challenges as no alterations to the building were allowed. Further challenges included the fact that the chosen areas were situated in the Ramparts – domed rooms with 900mm concrete walls.

After the initial designs our interior designer did a full set of high quality 3D renders for approval by the client before we did the detail designs. These renders were used by the Client to determine their “Look and Feel” finishes. These finishes for the acoustic treatment were designed by the interior team to reflect an authentic South African aesthetic.

Entering the facility, one feels as if you were entering a century old building, rustic original finishes with concrete floors, concrete white washed walls and domed soffits until you reach the studio area that stuns you with a high-end, state of the art recording facility.

The original rooms were complex acoustic environments with domed concrete ceilings and hard walls and floors. In addition the Heritage Board stipulated that – no alterations to the building would be allowed, we had to come up with a design that not only gave excellent isolation, but also created an acoustic environment that was free from echoes and standing waves while ensuring a studio that was not too dead.

The acoustic treatment in the Studios, Control Room, Voice Booth, Green Rooms and Rehearsal Room included a combination of absorption panels, custom wall and ceiling diffusers, bass traps and acoustic clouds.

To keep the heritage site intact, we designed steel frames to sit on the floor, taking the shape of the rooms and then fixing the acoustic walls and acoustics, windows and doors to these frames. The floors are suspended engineered timber floors that sit on rubber cradles.

Glass reveal panels in the acoustic treatment and in the floors are lined with hidden LED lights that highlight historical elements of the original building.

One of the major challenges on the design of the studios was the air-con design. Due to the fact that we could not cut holes into or alter the building, we had to place the air handling units in the studio area and in the sound lock for the control room. The ducting and the attenuators were built into the walls of the studio. In the control room the supply attenuator and duct form part of the couch behind the sound engineer. Even with the strict heritage requirements we achieved noise figures of <NC25.

The recording system, based on the ProTools S6 mixer, a S6 M40 32-5D, with 32 faders and 4 display modules is one of the biggest recording mixers in South Africa.

The control room monitoring is a 5.1 Genelec Speaker system. The monitoring set-up in the control room was done on the ProTools MTRX Speaker Processing Card – this, in conjunction with the acoustic design ensured a flat frequency response from the sound engineer’s listening position.

As there was a limit on cable ways, all wiring between the areas are fibre links on a Dante back-bone. Recordings can take place from the Studio, the Voice Booth, the Green Room and the Rehearsal Room.
