The Product
The Electro-Voice Q99 is a solid and dependable power amplifier whose design is based upon the industry standard P Series, delivering 900W per channel into a 4Ω load and 1500W into a 2Ω load. It employs an efficient class H design, where the permanent voltage rail is designed to cover the average music signal, rather than supplying the voltage for maximum output power. If dynamic peaks require a higher output voltage, the voltage rail is switched to the maximum. This process saves up to 50% of the power consumption found in conventional amplifier designs.
Other features include a comprehensive protection system against overheating, overload, short circuits, HF and DC and a patented LPN filter with switchable frequency and phase response correction of connected loudspeakers. Audio inputs are balanced and presented on XLR connectors with loop-through outputs for daisy-chaining to other amplifiers and the audio outputs are on locking Speakon connectors. Mains power is supplied via a standard 3 pole IEC connector. Input level is controlled by front panel mounted rotary controls with a pair of 5 segment LED meters giving clear indication of levels, with additional signal limit, clip and power LED indicators. A main power rocker switch is also located on the front panel for ease of access.
The Manufacturer
Electro-Voice had very humble beginnings when in September 1927, Lou Burroughs and Al Kahn began a small business servicing radio receivers in South Bend, Indiana. As a consequence of the Great Depression, they soon found themselves insolvent owing $5,000. This provided enough of an incentive for them to move their business in the direction of audio products, and in June 1930, they incorporated their business under the name Electro-Voice. At the time both Burroughs and Kahn felt that microphone designs around were of poor quality and over priced so they purchased a lathe and a drill and started producing about one microphone a week. Not long after Burroughs left the business, leaving complete ownership to Kahn. By 1933, the previous business debts were completely paid off and Electro-Voice began hiring employees to help in the production of the new designs. In 1936, twenty people were hired and Lou Burroughs returned as chief engineer.
Throughout the 40s, 50's and 60's Electro-Voice continued to grow and innovate producing a variety of products such as phonograph pickup cartridges and the first automatic TV booster. Loudspeakers and microphones joined their portfolio and with the brand gaining popularity and respect in the music industry Electro-Voice was established as a household name. In 1998 EV merged with equipment manufacturer Telex Communications, then in June 2006, EV, along with all of Telex Communications, became part of Bosch Security Systems division. Today EV is highly respected and continues to manufacture widely used broadcast microphones as well as loudspeakers and various other professional audio equipment.
