Wohler AMP1A-SUM6 High Quality Analog Self-Powered Speaker System
Wohler AMP1A-SUM6 Compact, High Quality Analog Self-Powered Speaker System - 6 Channel, Summed
The AMP1A-SUM6 provides self-powered,full-fidelity stereo audio monitoring in the smallest rack space possible. The AMP1A-SUM6 offers 6 separate analog inputs which are then summed together: 3 to the left and 3 to the right, 6 separate volume controls allow the operator complete controlof the output.
This unit contains four high performancetransducers driven by three power amplifiers: one amplifier/driver combination handles midrange and high frequency information in stereo, while the second handles summed low frequency information below the 500 Hz crossover point.
The unique design provides optimally focused sound for operators in an Ultra Near Field (1 to 3 ft.) working environment and offers performance comparable to that of many separate monitor pairs, yet does so without the installation hassles, awkward speaker placements and "added-on" look. This provides for a higher SPL for the operator while reducing overall ambient sound and adjacent bay crosstalk.
Extended HF response reveals potential problems with audio whine or hiss and electronic rather than acoustic cancellation of bass frequencies provides positive audible detection of out-of-phase (reversed polarity) audio feeds.
A headphone jack is provided on the front panel, usage automatically mutes the speakers. Output limiter circuits are incorporated to protect the speakers, and extensive magnetic shielding allows placement immediately adjacent to video monitors with no color impurities.
The AMP1A-SUM6 is ideally suited for use in VTR bays, mobile production vehicles, teleconferencing installations, multimedia systems, satellite link and cable TV facilities, and on-air radio studios. Built and rigorouslytested in the USA, the AMP1A-SUM6 is backed by a strong warranty and a "Satisfaction Guaranteed" return policy.
