The Weber attenuator is outlined as an digital machine designed to cut back a sign’s amplitude and energy with minimal or no distortion to that sign’s waveform. As compared with different attenuators such because the Final Attenuator and the digital attenuator, this type of attenuator makes use of rheostats. The rheostats are use to regulate attenuation and to distribute energy to the speaker motor or different load. The 2 sorts of this type of attenuator are the speaker motor mannequin and the resistive or resistor-based mannequin. The speaker motor mannequin makes use of an precise speaker motor to generate a reactive load on the amplifier. The resistive mannequin of Weber attenuator creates a purely resistive load on the amplifier utilizing energy resistors.
One benefit of the speaker motor mannequin over the resistive mannequin is that it offers a extra interactive, pure sound. This Weber energy attenuator additionally has much less impression on the tone as in comparison with the resistor-based mannequin. There are a number of sorts of speaker motor-based attenuators. They’re the Mobility Analog System Simulator (MASS), MiniMASS, MicroMASS, MASS 150, Energy Faucet, MASS Lite and Stereo MASS. The MASS sort makes use of a speaker motor in order that the load will give a practical interplay between the output circuit of the amplifier and the attenuator. The MASS unit accommodates a line out reference to entrance panel controls for mids, bass, quantity and treble. These management panels are helpful for shoppers who plan to run easy direct out indicators. Shoppers within the wet-dry strategy additionally discover these management panels efficient. The MicroMASS and the MASS Lite fashions include two energy degree controls. One management is utilized for the bass-mid frequencies and the opposite one is for the higher mids-treble frequencies. In the meantime, attenuation is constantly adjustable from zero to over -50 db within the MiniMASS mannequin. The MASS 150 unit options additional output jack, MASS bypass, line out and vary swap. The Stereo MASS doesn’t comprise a line out but it surely has treble compensation in-built. The Energy Faucet unit options treble compensation, vary swap, and a -20 db fastened line out.
The resistive mannequin of Weber attenuator contains the Low Energy Load Dump, Excessive Energy Load Dump, Mega Dump and Headphone Faucet. As in comparison with the motor speaker-based MASS, the Low Energy Load Dump unit is smoother and never as interactive. Its attenuation is constantly adjustable from zero to over -50 db. The Excessive Energy Load Dump mannequin with 200 watt energy makes use of energy resistors and capacitors. This mannequin makes use of 11 steps of output management on a rotary swap. The Headphone Faucet unit is known as a 50 watt dummy load which consists of a headphone output jack. Lastly, the Mega Dump mannequin includes system bypass, vary swap, adjustable line out, and 0, 3, and 6 db treble boosts.
Based on product evaluation and producer’s declare, this attenuator is usually hand-built. This ensures prospects that they’re shopping for merchandise of highest high quality. Among the equipment accessible for Weber attenuator embrace 1 ft RCA cellphone plug to ¼ cellphone plug, 59 Bassman Attenuator Harness, Rackmount Wings for the Mega Dump and MASS 200 models, and attenuator harness for Peavey amplifiers.
