Smart SMS Sound Masking System

Smart SMS Sound Masking System

SMS-AMP

The Soft dB's SMS-AMP is a DSP-based system that provides unique adjustment functions and ensures the generation of the
optimum masking sound regardless of the characteristics of the room.

Automatic Equalization Process: Adjusts automatically the masking spectrum for the specific architectural characteristics of

the building. The adjustment is quick and precise.

Active Adjustment of the Masking Sound Level: Continuously measures the ambient noise and automatically adjusts the

masking sound level accordingly. It maximizes the privacy in the treated space while preserving the occupants' comfort.

The SMS-AMP is available in 1, 2, 4 or 8 channel versions, and integrates the controller, the noise generators, the equalizers and the
25-Volt amplifiers. It combines sound masking, music diffusion and paging systems, all integrated in one convenient rackmount
package.

Features

Fully adjustable output channels, e.g. 1/3 octave equalizers (± 0,1 dB adjustment).
Auxilliary inputs for music or paging, 1/3 octave band equalizer on each output.
Up to 8 SMS-AMP units can be networked through a USB if more than 8 channels are needed.
Inputs for active sound level sensors.
Programmable phase-in timer (up to 2 months).
Volume control knob allows easy volume adjustments.
The DSP processor is controlled from a PC connected through a USB port.
Includes a UL and FCC certified 110-240VAC - 25 VDC external power supply.
Optional internal clock for calendar function allows time-based automatic adjustments.

Active Adjustment Features

Unique active adjustment system which controls the masking volume based on the level of disturbing noise of the room.
The disturbing noise is measured by sound level sensors installed in the ceiling. Up to 8 sensors per zone.
The masking sound level is adjusted automatically in real-time.
Rate of adjustment, high limit and low limit are programmable separately on each output.
Input mixer allows the combination of any active input with any output channel.

Automatic Equalization Process Features

Integrated 1/3-octave frequency analyzer, real-time measurement of the masking spectrum during the calibration.
Optional wireless connection between the computer and the SmartSMS allows to easily perform the equalization alone.
Automatic calculation of the masking sound ensure generation of the target masking sound in the room.
Different target masking sound spectrums can be applied to different zones.
A bank of target spectrums is available, spectrum editor function allows to create custom spectrums.
Equalization can be performed manually, if desired, with a 1/3-octave band equalizer.
