The ET450 induction loop amplifier is the largest of the easy T professional range of induction loop amplifiers. The ET450 loop amp will cover a square room 21m by 21m or a rectangular room 40m by 20m. The ET450 induction loop system has three inputs all of which can be microphones, or input 3 can be switched to line level for mixing desk or AV feeds. Selectable Phantom power is available for the microphone inputs. All the controls on the ET450 are screwdriver adjustable to prevent tampering. Each input has its’ own mix control, before passing to a compressor limiter.

The unit has three inputs all of which can be microphones, or input 3 can be switched to line level for mixing desk or AV feeds. Selectable Phantom power is available for the microphone inputs.

The controls on the Current Thinking ET450 Loop Amplifier are screwdriver adjustable to prevent tampering. The three audio inputs on the ET450 are on standard XLR Connections (in accordance with AES3).

The amplifiers have 3 inputs on XLR; 2 dedicated microphones and one microphone or line selectable using a rear panel switch. User selectable Phantom Powering is available for the microphone inputs, enabled via a rear panel switch. The inputs are individually mixed before passing to the compressor limiter, which prevents loop overload whilst compensating for varying microphone usage.

All controls are recessed to prevent unauthorised access. Indication is provided for compression level, output current, loop status and power supply. A loop current monitor socket is provided to allow headphones to be used to monitor the actual loop current. An audio output (post compressor) is provided for recording, with a slave audio in to allow cascading.

Inputs 1 & 2 are microphone level and input 3 is selectable between mic and line level using the blue push switch on the rear. Phantom is enabled to all microphone inputs using the red push switch on the rear.
