Transformers Inter-M The OT Series output transformer units convert the 4 output of a low-impedance amplifier to 70/100V high-impedance

The OT Series output transformer units convert the 4ž output of a low-impedance amplifier to 70/100V high-impedance levels. Outfitted with four outputs providing as many as four independent mono channels or two separate sets of stereo channels, each OT Series model (OT-4240, OT-4480, and OT-4960) offers a quick, simple way to add 70/100V line transformer capabilities to a low-impedance amplifier. Although these output transformer units were originally designed to be used with the Quad Series power amplifiers, they may be used with any other professional low-impedance amp. The Quad Series power amplifiers each offer four channels of amplification, as well as features such as fan cooling, fail-safe protective circuitry, an operable range extending from 20 kHz to 50 kHz, balanced inputs, and a signal-to-noise ratio of 105 dB.

Digital Snake Products


The AN-16/i input module, the AN-16/o output module, and the A-16SB system bridge are designed to work together to create a powerful digital-audio snake, capable of digitally transferring high-quality 24-bit audio over Cat-5 cables. The proprietary A-Net Protocol ensures that there is less than 1 ms of latency from analog input to analog output. The A-16SB, AN-16/i, and AN-16/o are compatible with the company’s existing product line, which includes the modular A-16 personal monitor mixing system. The digital snake is a flexible modular system that allows you to build unidirectional or bidirectional configurations to suit most audio distribution needs.
