The APM-215 Stereo Audio Program Monitor offers excellent audio fidelity in a compact 1RU design. This device is engineered to easily integrate with advanced Harris® Videotek® test and measurement instruments (including the VTM Series™ multi-format monitors and TVM Series™ multi-format signal analyzers) via loop input interfaces and the included 37-pin audio adapter cable, making it an ideal multi-purpose monitoring solution.
Product Details
The high-quality audio and low distortion of the APM-215 monitor are achieved through a bi-directional speaker system along with a wide volume control range and balance adjustment. Input mode switching can be done directly from the front panel, allowing for stereo monitoring of up to 10 different channels. The APM-215 features two 10-segment color LED bar graph meters and phase indication LEDs, and the headphone jack on the front panel allows for muting the speaker output to meet isolation monitoring requirements. Its magnetic shielding capability enables the APM-215 to be used near waveform or image monitors without causing electromagnetic interference, making it highly suitable for live broadcast trucks, editing suites, VTR monitor racks, or any other systems requiring high-quality professional monitoring of stereo audio signals.
