User manual ROLLS MX410

[. . . ] The MX410 Phantom Power utilizes a fixed DC voltage which is resistively applied to pin-2 and pin-3 of an XLR input connector relative to pin-1 (there is no voltage difference between the signal on pins 2 and 3; a dynamic microphone may or may not operate normally in the presence of phantom power). It is generally a good practice to turn off phantom powering when not using a condenser microphone, as it can capacitively couple noise into the mic inputs with poor mic cables. Also, be sure to turn off phantom powering when using ribbon microphones since an improperly wired cable can permanently damage the microphone.

PLEASE MAKE SURE THAT THE REAR MIC/LINE SWITCH IS IN THE CORRECT POSITION FOR YOUR INTENDED USE. [. . . ] This way the MX410 output is attenuated down, and will be more compatible with an input looking for a microphone level signal. POWERING To power the MX410 and get it ready for operation: 1. Insert - 2, 9-Volt, alkaline batteries into the battery compartments. Or, connect external DC power (the Rolls PS27) 12 VDC to the MX410 DC Input connector. Press in the POWER button. INPUT CHANNEL SETUP To set up a gain level for an input channel: 1. Connect a signal source (microphone) to a channel input connector. If you're using a condenser microphone, activate the Phantom Power by depressing the phan switch. Set the LEVEL Control at the 12 O'clock position (again - just a starting point). Set the channel L C R switch for the desired signal position in the stereo field. Engage the side panel "low cut" switch if needed. Verify there is signal present on the output meter(s). INDIVIDUAL CHANNEL LEVEL CONTROLS The Level is the primary channel volume control. Level can be set to a nominal level (around 12 O'clock) providing the maximum amount of variance and headroom. L C R SWITCHES (Left - Center - Right) The Stereo orientation switches routes an input channels signal between the Left, Right and both outputs. METERING The MX410 features two calibrated, LED meters. Meter ballistics correspond closely to how the human ear perceives loudness and provides a good visual indication of how loud a signal will be. OUTPUT CONNECTION To connect to the MX410 main Outputs: 1. Connect an XLR cable to the LEFT and RIGHT Outputs of the MX410. Set the output level switch to either LINE (switch in), or MIC (switch out). Verify that the next device in the signal chain is receiving signal from the MX410. HEADPHONE MONITORING 1. Connect stereo headphones to the HEADPHONE output on the front panel. NOTE: THESE MUST BE STEREO HEADPHONES OR EARPHONES - USING MONO PHONES WILL DAMAGE THE MX410. Verify signal in the phones by slowly bringing up the PHONES level control.
