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 with 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.

Applications:
The SMS-AMP Sound Masking System only
requires to be connected to 25-Volt speakers to
generate masking sound. All the sound
generators, equalizers, mixers and amplifiers
are included in one simple rackmount unit.

Smart Software
The Smart SMS Software performs auto-calibration (patent pending 2,471,674) and real-time
frequency analyses of the sound masking.
Note that the software can be used with many Smart SMS units connected together. |
- Automatic or manual adjustment of the masking spectrum for each channel
- Built-in frequency analyzer in 1/3 octave and narrow bands
- Real time display of masking spectrum in the room
- Rising time adjustment of sound masking (from 1 second to 6 months)
- Function for saving measurements and parameters for reports, follow-ups or modifications
- Internet access to system to change set up

Smart Speakers
 |
 |
- The Smart SMS System uses full-range hi-fi speakers in custom-made casings
- Each speaker is tested during production to ensure a consistent frequency response between units
- Each speaker comes with a flexible cable for easy attachment
- In modern offices without suspended ceilings or with particular installations, the speakers
are available in different colors or with custom-made attachments for an
additional charge
