Visual Sound, Inc. Teleloop Amplifiers PL150, PL300, PL450

Phonic Ear, Inc. These tree amplifiers covers up to 800m2 (8656 feet2) and have three balanced inputs on XLR; two 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 while compensating for varying microphone usage.
