-AVLELEC's SMG-1 provides a digital noise signal for soundmasking applications. -compact shelf mount chassis style -versatile outputs include a high impedance line and a balanced line that may be switched between line level and mic level. -plugs directly into existing Sound / Paging System to convert into a Soundmasking System or use stand-alone |
- AVLELEC SMGA-5 is a masking
generator with 5W amplifier. Compact 1RU device is ideal for small
stand-alone masking or masking with paging installations. It may also be
used to add masking capability to an existing paging system or zoned
area. The generator produces the pink noise signal for sound masking. The built-in amplifier (5W into 70V, 25V, or 8ohm) may be used for paging, music, or signaling sources. System controls include output level and an adjustable low pass filter, level adjustment for the auxiliary input signal, noise level, master level and individual tone controls for shaping bass, midrange, and treble frequencies. |
- AVLELEC SMGA20 provides the digital noise signal and
amplification (70V, 25V, or 8 ohm output) for sound masking
applications. Outputs include balanced line or mic level (Low-Z) and high impedance line (Hi-Z). Line output and auxiliary input can be configured to utilize an external equalizer. Unit also includes bass, mid, and treble tone controls.

AVLELEC Computer Model SMG-3001
DSP Sound Masking Generator w/ Event Scheduling The MG3001 represents the latest technology in digital signal processing (DSP) engines for sound masking generator/equalizers. This model features two built-in digital noise generators and two analog noise generators allowing the versatility of digital, analog, or mixed noise at either of its two outputs. Each noise source is separately adjustable–between 80dBu and 0dBu in 0.1dB steps. The SMG-3001 offers a variety of user selectable filter options including one-third octave, parametric high/low pass, and high/low shelving filters. Each filter offers precision .1dB level and 1 Hz frequency steps. All set-up and operating functions of the SMG-3001 are conducted from a PC using software provided for Windows 95/98/2000/XP/NT4. After defining and downloading the control functions through the PC, the settings will be stored within the unit in non-volatile memory (no battery required). The SMG-3001 model features 12 storage memories and 12 preset functions. The unit occupies one rack space unit (13/4") with a depth of 10" behind the front panel. It contains a built-in power supply capable of operating between 94-260 VAC at either 50 or 60 Hz. The MG3001 includes a clock circuit that allows for varying parameters at different times of day. The device will ramp up gradually so that workers do not notice a difference in the noise level. |

AVLELEC SMG-2500 DSP Sound Masking Generator w/Page Input AVLELEC SMG-2500 Sound Masking Processor is a digital pink-noise generator that includes a balanced line-level audio input and a 2-channel DSP processor, all in a single rack-space unit. An extended ‘non-apparent’ repeat time of noise (200 minutes) and output delay with distance/delay calculation, per channel helps insure the masking source will not be decoded in high security installations. The SMG-2500 includes two independent matrixes for channel-to-channel mixing and balanced input & outputs on plug-in barrier strip connectors. Noise & audio levels, plus two channels of combined 1/3-octave & parametric equalization, EQ, gain management & delay, are adjusted via computer software (Windows 95/98/2000/XP/NT4). Sixteen presets can also be recalled via contact-closures, RS-232, or other remote control options.There are no manual controls on front panel, to prevent tampering. All programming software & serial cable included. UL Listed. |
