The SR107 is used in sound system applications for the purposes of feedback control in live performances, playback equalization (correcting for equipment response and/or room acoustics in prerecorded performances), and improvement in the sound quality of live performances. Equipment response correction includes the elimination of such problems as transducer incompatibility, overload at low frequencies (rumble), tape hiss and disc surface noise. The SR107 is a balanced input and output line level device, designed primarily for installation between the audio console or mixer and the power amplifier of the sound system. DESCRIPTION The SR107 has ten octave band, minimum phase, combining type filters centered on ISO? preferred frequencies from 31 Hz to 16 kHz. Each filter is adjustable for approximately 15 dB of boost or attenuation. The equalized output is adjustable over a 2 1 5 dB range, and overall gain of up to 20 dB may be introduced to compensate for low input signals. A peak-responding overload lightemitting diode (LED) is provided on the front panel. The SR107 contains both professional three-pin and phone jack input and output connectors, and a phone jack auxiliary output. The SR107 is designed for maximum simplicity of operation and maintenance. All components are of the highest quality and are operated well within their respective ratings to assure maximum reliability under normal use conditions. The SR107 and SR107-2E are identical except that the SR107 operates from 108-132 Vac, 50/60 Hz and the SR107-2E operates from either 105-125 or 210-250 Vac, 50/60 Hz (switch-selectable). The SR107-2E is supplied with a detachable ac line cord (without power plug). The SR107 (only) is listed by Underwriters' Laboratories, Inc., and is listed by Canadian Standards Association as certified. All SR107 units are supplied with four rack-mounting screws for mounting in standard 19-inch (483 mm) audio equipment racks or in optional Shure A30A or A105A Carrying Cases. An optional protective cover, Shure Model A107A, is also available.
