Parlé Presenter Lift: Installation and Pre-Commissioning

Applicable hardware and software

This article applies to the following Biamp hardware and software:

• Microphones: Parlé TCM-X, Parlé TCM-XA, Parlé TTM-X

• PoE Amps: AMP-450P, AMP-450BP

• Processors: TesiraFORTE X (and Voltera D and DM products in special cases)

• Software: Tesira Software 5.4 or newer, Presentation Space Designer

Prerequisites for this PPL step

• A completed Presentation Space Designer report from the design phase.

• A project-specific initial Tesira file with the core PPL blocks, as outlined in the design article.

• All required Biamp hardware on-site.

• A calibrated SPL meter capable of A-weighted measurements.

• A tool for measuring RT60 (reverberation time).

• A reliable laser tape measure.

• A thorough understanding of the Parlé Presenter Lift: System Overview article.

 

 

Physical Placement

• Install Microphones per Design Layout - Install the Parlé TCM-X, TCM-XA, or TTM-X microphone(s) exactly as specified in the Presentation Space Designer layout. For best performance, this is often directly above the front edge of the defined presentation area.
• Verify Physical Placement - If the system design utilizes multiple Parlé microphones, use the Locate Devices to identify and correct the installation to match the design placement.

• Note: This is also an ideal time to update the device host names to help identify their location in the space (e.g. TCM-X-Instructor Desk).

 

Physical Orientation

• Establish Physical Orientation - The microphone must be oriented correctly relative to the room. The small Biamp logo on the microphone indicates the 0° azimuth. This logo should be pointed toward "room south" or typically facing away from the main presentation screen or front wall.
• Verify Orientation from Software - Use the Orient Mics option in the Parlé block control dialog. This will display a red and green LED on the physical microphone array that aligns with the default red and green zones shown in the software.
  • Green = Biamp Logo = 0° azimuth = Faces "room south"
  • Red = 180° azimuth = Faces "room north/screen"

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

            

 

 

 

 

 

 

 

 

 

 

Physical Placement

• Install Loudspeakers - Install loudspeakers according to the design plan.
• Update the Design with Measured Locations - Since Presentation Space Designer becomes part of the commissioning process, mounting locations of each loudspeaker should be measured from the front wall and left wall of the room, and updated in the web tool.
• Adjust Placement in the Tool - As the user moves the loudspeaker in the web tool, the distance from each respective wall is shown in real time. Move the loudspeaker to match the measured dimensions in the actual room.

• Verify Coverage and Microphone Spacing - Ensure that coverage is focused tightly on the audience seating areas while keeping a 6 ft. offset from the nearest microphones.
• Verify Speaker-to-Amplifier Wiring - If the system design utilizes multiple Parlé amplifiers or AMP-450 PoE amps, use the Locate Devices to identify and correct the installation to match the design placement. This is convenient as it will play channel-specific audio tracks to help identify which loudspeaker is wired to which amplifier channel.

• Note: This is also an ideal time to update the device host names to help identify their location in the space (ie. TCM-XA-Instructor Desk, AMP-450BP-Row-1).

Verify Wiring

• Verify Channel Assignments - Double-check that each loudspeaker zone is wired to the correct amplifier channel as defined in the system design. This may have already been accomplished with the Verify Speaker-to-Amplifier Wiring step in the above section.
• Note: An error here (e.g., swapping the wiring for the front and back rows) will make proper gain shading impossible.
