FAQ

Damping Materials Used in Our Monitors

Genelec products use various damping materials such as glass fiber wool, linen fiber wool, and polyester fiber based material (PES). The tables presented below provide a detailed listing of our monitor models and the type of damping material used in each model.

During operation, the air moving in and out of the monitor loudspeaker or subwoofer bass reflex openings does not emit significant amounts of fiber particle dust. The PES wool as material does not emit dust. The linen wool, and glass fiber wool can emit minimum amounts of dust during very high sound level operation. This fiber dust is not hazardous to health.

Input sensitivity can be controlled with a combination of a rotary controller and level range switches on the products. The sensitivity on SAM™ (Smart Active Monitoring) products can be set more precisely using the GLM (Genelec Loudspeaker Manager) software and a computer.

The nominal analogue input sensitivity in Genelec studio monitors is -6 dBu which produces 100 dB SPL audio output at 1 meter in an anechoic room.

The nominal digital input sensitivity is set so that a 0 dB FS digital input produces a theoretical 130 dB SPL sound level at 1 meter in an anechoic room.

The actual maximum SPL depends on the product capabilities and may be lower than 130 dB SPL.

Acoustic treatment

This is a very broad subject area covering room geometry, reverberation time, sound reflection and refraction, material properties, etc. However, we built a brief checklist to cover the most important features that a listening room should have. Once the room has been acoustically treated the studio monitors can be installed.

A Brief Checklist for Listening Room Setup
  • Ensure that the reverberation time is low and approximately constant with frequency.
  • Primary sources of reflection should be treated, so that reflected levels are at least 10 dB down from the direct sound pressure level at least during the first 15 ms after the arrival of the direct sound at the listening location.
  • The front wall should be hard and smooth if monitors are flush-mounted. The front wall can be absorptive if monitors are free-standing.
Setting Up Studio Monitors
  • Position the monitors according to the standard orientations (angles) from the listening position.
  • Position monitors at equal physical distance from the listening position, or use GLM AutoCal to electronically compensate for differences in monitor distances.
  • Position the monitors so that there are no cancellation effects from the side walls and the wall behind the monitor.
  • Turn the monitors towards the listening position horizontally and vertically.
  • Set the room compensation controls as suggested in the Operating Manual/Quick Setup Guide or use GLM AutoCal to compensate for the room acoustics in the case of SAM (Smart Active Monitoring) systems.
