PIX 220i and PIX 240i Video Recorder User Guiderates of 48 kHz. All digital signals connected to PIX are sampling rate converted to 48 kHz, includingsignals sent at 48 kHz.Input LinkingSetup Menu option: Audio Input LinkingInputs 1-2 can be linked together so that a gain adjustment to one channel will also affect the other(See “Input Level Control”, page 21). When inputs 1-2 are linked, the limiters are also linked. 48Vphantom power, analog low-cut, and analog polarity settings are set independently for each channel,even when inputs are linked.Linked inputs are useful when the PIX is receiving a left/right stereo signal on inputs 1 and 2. Examplesinclude stereo program from an external mixer, stereo program from a camera, and microphonesoriented in a stereo configuration.M/S MatrixingMid-side (MS) matrixing is a method for processing audio signal from a cardioid microphone and abidirectional microphone into a stereo signal. The cardioid microphone is the “mid” signal and connectsto input 1, and the bidirectional microphone is the “side” signal and connects to input 2. Thecardioid microphone is pointed at the sound source, and the bidirectional microphone is orientedsideways (positioned with its capsule as near as possible to the cardioid microphone’s capsule). thefollowing diagram shows the relative polar patterns of microphones in an M/S configuration.Audio InputsMid SignalSide SignalTo produce a stereo signal from an M/S configuration, the signal from both microphones must beprocessed. The PIX recorder can perform this processing on inputs 1 and 2 when Setup Menu optionAudio Input Linking is set to 1-2MS.Choosing Audio SourcesThe PIX recorders are capable of recording audio from the two analog audio inputs or digital sources(AES3 or video input). The Setup Menu option Audio Audio Input provides the following optionsfor audio sources:Audio SourceAnalog XLR 1: Analog Input XLR 12: Analog Input XLR 2AES (Digital) XLR 1-2ch 1: Channel 1, AES XLR A2: Channel 2, AES XLR AAES (Digital) XLR 1-4ch 1: Channel 1, AES XLR A2: Channel 2, AES XLR ATracks on Recorded Files and Video Outputs3: Channel 1, AES XLR B4: Channel 2, AES XLR B20v. 3.52 Features and specifications are subject to change.
