A sophisticated Universal Switching Power Supply with Power Factor Correction ensures exceptionally smooth operation with a huge regulated power output. An additional shielded line filter, magnetically and electrically shielded supply cover and out of phase operation of the second amplifier channel add significant performance improvements and allows for approved mains use in almost all countries worldwide.

To achieve identical characteristics both inverting and non-inverting, we chose a “no compromise” instrumentation amplifier for input interfacing duties vs more traditional single op amp solutions. A version with JT-10KB-DPC input transformers replacing the active circuitry is also available by special order for high noise environments

The amplifiers provide protection from over temperature, over current, excessive H.F., D.C., over/under supply voltage, and a clip-limiter.  The current limiter will allow peak currents of 30A with audio signals without taking action, while the clip-limiter will begin to reduce the audio input signal until the output current is lowered. If the clip-limiter is not capable of limiting the output current enough, the amplifier will disable to protect itself. A multifunction display that changes the colour of our logo quickly indicates “protect”, “operate”, and “clip-limiting” of the amplifier. A discrete ring on the power switch indicates the standby condition.

The input can switched via a back panel toggle between unbalanced (RCA) and balanced (XLR) operation with effective isolation between the two inputs. This feature can be used to select between two discrete inputs or as a mute/operate switch with one source. Remote operation of an amplifier is accessible via two internally paralleled 3.5mm connectors using anywhere from 4 to 20Vdc as a trigger. A user programmable microprocessor and a field serviceable analogue module allow for simple and cost effective future expansion or modification.  Proposed modules include speaker compensation boards, electronic crossovers, wireless signal input, etc…\
