INTRODUCTION: The USB Phono Plus is a high quality USB audio interface with a built-in phono preamp. It acts as an interface between your computer and a wide variety of analog and digital sources. The analog inputs are switchable between Phono and Line level signals and a Low Cut filter removes rumble and wind noise while leaving the audio pristine. The front Gain Trim control and Signal/Clip LED allow you to optimize the analog to digital converter for a wide range of input sources.
CONNECTIONS: The Preamp Phono/Line In connections are RCA-type jacks and are used to connect your turntable, tape, CD, MP3 player, or other analog stereo audio device to the USB Phono Plus. The Ground terminal connection on the rear is used to connect the separate ground wire from your turntable to reduce hum. (This connection is unnecessary for digital output turntables).
CONTROLS: The Input switch sets the gain and equalization of the analog preamp. If using a phono turntable, set the switch to Phono. Otherwise set the switch to Line for other types of audio sources. The Filter switch, when in the Low Cut position, adds a filter for removing turntable rumble or other low frequency noise. The Gain Trim control adjusts the overall analog preamp gain.
INSTALLATION: 1. Connect your turntable, tape player, CD player or other analog audio device cables to the RCA input connectors or connect your digital audio device to the S/PDIF or OPTO inputs on the USB Phono Plus. a. If you are using a turntable and it has a separate ground wire, attach it to the ground terminal on the USB Phono Plus. This will help to reduce hum. b. Select LINE or PHONO input for the analog source type.
USB COMPUTER SETTINGS: Once the USB connection is made and your computer is on, your computer will power the USB interfaces circuitry over the USB bus and the unit will automatically connect and try to set your computer “Default Audio Device” to be “USB Audio CODEC”. Usually the computer will do this automatically whenever a USB device is first connected, but it is sometimes necessary to make the selection manually.
