The 4-Channel Audio Interface Adapter from Louroe Electronics is a 4-zone interface unit that can connect up to 4 Louroe microphones to a DVR or any other recording device with line level inputs. This interface adapter features an RCA and a 3.5mm (mini jack) stereo output. This dual output functionality facilitates flexibility of connectivity, and enables you to send the audio signals from the microphones to devices with RCA or 3.5mm inputs. The interface adapter's audio level control potentiometer allows you to vary the audio gain, as per your requirements, to prevent overdriving or underdriving of the audio signals. The included audio test switch notifies the end user that audio signals are being delivered to the audio recording device. With an LED bulb, the test switch indicates whenever an audio signal is detected.
