The Apex 555 USB Condenser Microphone with Active Monitoring delivers the performance and tone of a professional studio quality side address FET microphone with the convenience and simplicity of direct to digital USB 2.0 connection to any computer or laptop. An 1/8th-inch stereo headphone output jack with volume and source mix control integrated into the microphone chassis allows the Apex 555 to act as its own audio interface. The volume control sets the overall listening level in the headphones, while the mix control blends the computer audio (playback mix) and source (microphone input) to the headphone mix, making the Apex 555 a zero-latency all-in-one recording solution.
