User manual RANE ML 1

[. . . ] To talk to the digital audio world, connect to your choice of AES3, SPDIF or TOSLINK digital audio outputs. Observe that the POWER LED on the front panel illuminates. Now you may turn on any power amps and make final adjustments with the GAIN controls. WEAR PARTS: This product contains no wear parts. Manual- Operation Details ML 1 1 2 1 2 MIC / LINE PREAMP INPUT OUTPUT POWER Analog Connections The ML 1 has two balanced analog Inputs, two balanced analog Outputs. XLR and euroblock connectors are both provided for your convenience. [. . . ] This configures the input of the ML 1 as a high-performance line stage that happily accepts the hot +24 dBu signals from professional audio sources. When using non-pro -10 dBV audio sources, set the GAIN control to +12 dB line gain by rotating it to the 2:00 position. When you're hooking up a consumer CD player with a single- ended output (for example) and you really need an extra 6 dB of gain (for a total of 18 dB of front-end gain), set the GAIN control just past the 3:00 position. Analog Output Stage Analog output is real easy. All gain in the ML 1 is adjusted at the Inputs just as it should be. It's OK to use all of the analog Outputs at the same time and to use the analog and the digital outputs together. Digital Outputs The ML1 has one AES3 Digital Output, one SPDIF Digital Output and one Optical Digital Output (also called TOSLINK). AES3 is a popular 2-channel (stereo) digital audio interface commonly found on professional digital audio equipment. Each channel of the AES3 digital stream is treated independently within the ML 1. Use the AES3 Output to: · Feed audio to an RPM 88/44/22/26z to create a 2-channel digital "bus" between devices. · Connect directly to the AES3 input of a digital mixer. · Connect directly to the AES3 input of a DAT machine for recording. The SPDIF coaxial and optical digital outputs allow the ML 1 to interface with a wide variety of commercial and semipro equipment. Just verify that the device connected to the ML 1's SPDIF digital outputs can accept 24-bit audio at a 48 kHz rate. All three digital outputs are always active and can be used simultaneously.

First, a red LED illuminates so that there is little doubt that phantom power is on. Second phantom power is turned on only for inputs that have the mic/line switch in the "MIC" position. Microphones can be plugged into the XLR connectors or the euroblock connectors and both connectors have phantom power available. Microphones receive a full 48 volts of Phantom Power from the ML 1. [. . . ] Output LEDs There is a bi-color green/red output LED for each channel on both the front and back of the ML 1. These LEDs light up green when there is a digital output signal present. They will be green most of the time as the digital output should always be active. The LEDs light up red instantaneously if the output waveform clips. [. . . ]
