Product Details
The APM-215 monitor’s high-quality audio and low distortion are attained using a two-way speaker system with a wide volume control range with balance adjustment. Front-panel, direct-input mode switching allows the selection of stereo monitoring for up to 10 different channels. Two 10-segment, color LED bargraph meters are provided, as well as a phase indication LED. A front-panel headphone jack mutes the speaker output for isolated listening requirements.
Shielding permits use adjacent to waveform or picture monitors without magnetic interference, making the APM-215 ideally suited for use in remote vans, editing suites, VTR monitor bridges or any system that requires high-quality, professional aural monitoring of stereo audio signals.
